I want to refresh two variables named profittext and sumtext which will be refreshed and echoed in the following places every few seconds. I know AJAX is needed to do this but how do i actually make it work ? The only way i found out was to refresh the content of the whole file. is there any way to refresh specific variables? Any answers will be greatly appreciated . Thank you very very much.
<table>
if($profitandloss<$zero) {
$profitText = "<div style=\"color: red;\">$profitandloss</div>";
} elseif ($profitandloss>$zero) {
$profitText = "<div style=\"color: green;\">$profitandloss</div>";
}
// for profit and loss counting
$sum+= $profitandloss;
//
echo "<tr><td>" . $row['trade_id'] .
"</td><td>" . $row['selection'] .
"</td><td>" . $row['date'] .
"</td><td>" . $row['type'] .
"</td><td>" . $row['size'] .
"</td><td>" . $row['bidprice'] .
"</td><td>" . $row['offerprice'] .
"</td><td>" . $row['stoploss'] .
"</td><td>" . $row['takeprofit'] .
"</td><td>" . $profitText .
"</td><td><a href ='delete.php?id=".
$row['trade_id']."'>X</a>
</td></tr>";
$profitandloss=0;
if($sum<$zero) {
$sumText = "<div style=\"color: red;\">$sum</div>";
} elseif ($sum>$zero) {
$sumText = "<div style=\"color: green;\">$sum</div>";
}
}
echo "</table><br>";
?>
<!DOCTYPE html>
<html>
<table style="border:1px solid black;">
<tr>
<th style="border:1px solid black;">Profit/Loss</th>
</tr>
<tr>
<td style="border:1px solid black;"><?php echo $sumText ;?></td>
</tr>
</table>

I struggled with the concept of how to structure such code when I first started too. Although it's not specific to your particular variables, here's a quick example for how to update a var through AJAX with jQuery/PHP.
Prologue: If this is something you're going to be doing often, you'll want to learn jQuery, rather than using normal javascript alone. There are lots of great, free, resources on how to learn jQuery. Alternatively, if you're not satisfied with the free tutorials online, this is an excellent book. I'll write the example in jQuery.
Design: Okay, so the way it works is this:
Set a timer in javascript to execute a particular function every X seconds (you DO NOT want to do it every second).
That function makes an AJAX call (with jQuery) to a .PHP file on the server, sending it the data necessary so that the .PHP code knows what to send back.
The .PHP code grabs the data required (e.g., with MySQL) encodes it in a JSON format, and exits.
A promise on the AJAX call is fired and the data sent from PHP is received. Process it as you will.
Repeat from step 2.
If you have any questions about what the code is doing, please ask.
AJAX.PHP
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$return_obj = array();
$request_obj = NULL;
// our AJAX call used "POST" as it's 'type', so we look in that
// variable.
if ( array_key_exists("func",$_POST) ) {
if ( $_POST['func'] === "get_update" ) {
if ( array_key_exists("which_var",$_POST) ) {
$which_var = $_POST['which_var'];
$which_var = $mysqli->real_escape_string($which_var); // should use prepared statements
// we sent 'num_people_logged_in' as our value here, so we'll be looking for a column/field
// with that value. this assumes that some other code, somewhere else,
// is regularly updating the table. it also assumes that there will only
// be a single row returned, which will hold the value.
$query = "SELECT '$which_var' FROM site_stats ";
if ( $result = $mysqli->query($query) ) {
if ( $row = $result->fetch_assoc() ) {
$request_obj[$which_var] = $row[$which_var];
}
}
}
}
}
$return_obj['request'] = $request_obj;
echo json_encode($return_obj);
die();
?>
MYCODE.JS
// this actually sends the AJAX request to the server.
function getUpdate() {
var jqXHR = $.ajax({
url : "ajax.php",
data : {
'func' : 'get_update',
'which_var' : 'num_people_logged_in'
},
dataType : 'json',
type : 'POST',
timeout : 10000
});
// attach 'promises' to the jqXHR object, which represents
// the AJAX call itself. 'promises' are, in this context,
// just events.
jqXHR.done(function(data,textStatus,jqXHR) {
// this executes if the AJAX call succeeded.
// the variable 'data' holds what the server
// sent us.
if ( ( data ) && ( data.request ) ) {
receiveUpdate(data.request);
}
});
jqXHR.fail(function(jqXHR,textStatus,errorThrown) {
// this executes if it failed
console.log("Fail: " + textStatus + " (" + errorThrown + ")");
});
jqXHR.always(function(a,textStatus,c){
// this executes either way, after .done or .fail
});
}
// this is called from jqXHR.done, on success
function receiveUpdate(request_obj) {
if ( request_obj.num_people_logged_in ) {
updateDOM(request_obj.num_people_logged_in);
}
}
function updateDOM(num_people_logged_in) {
if ( num_people_logged_in ) {
$("#mydiv > p.update").html("The updated value is: " + num_people_logged_in);
}
}
var timeoutID = null;
// setup our timer, to periodically make an
// AJAX call
function init() {
timeOutID = setInterval(function(){
getUpdate();
},5000);
}
// stop the timer
function cleanup() {
clearTimeout(timeoutID);
}

You will needd two PHP pages:
- one with HTML and JS, which periodicly makes ajax calls and puts the result to the HTML
- second with json (or even plain text) output of your dynamic data piece
Unfortunately, writing the full code in the answer is not someting that people do at stackoverflow, so just look at small example below, and try to figure out the missing parts.
http://jsfiddle.net/AMEqz/
var xhr = new XMLHttpRequest();
xhr.onload = function(r) {
// your render logic HERE
setTimeout(send, 1000);
}
function send() {
xhr.open("GET", "/", true);
xhr.send();
}
send();
p.s.: keep in mind that each ajax request will mean extra connection to your server, so make sure it can deal with the load ;)
Use a timer : https://developer.mozilla.org/en/docs/DOM/window.setInterval
setInterval(function(){
//update your var here
},1000);

I am trying to make an incredibly simple ajax call, but it wont work.
Here is the php side called by ajax( This returns the correct response )
<?php
$returnValue = '';
$allUploads = array_slice(scandir('./uploads'), 2);
$returnValue .= '<table>';
foreach ($allUploads as $upload) {
$returnValue .= '<tr><a href ="/uploads/' . $upload . '>' . $upload . '</a></tr>';
}
$returnValue .= '</table>';
echo($returnValue);
?>
And here is the javascript thats letting me down
<script>
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange =
function ()
{
if (this.readyState == 4 && this.status == 200)
{
alert(this.responseText);
document.getElementById("filedisplaytable").innerHTML = this.responseText;
}
};
xhttp.open("GET", "listuploads.php", true);
xhttp.send();
</script>
Worst thing about this is, that the alert statement is outputting exactly what I want to write:
<table>
<tr>
<a href ="/uploads/DSC001.jpg>DSC001.jpg</a></tr><tr><a href ="/uploads/DSC002.jpg>DSC002.jpg</a>
</tr>
<tr>
<a href ="/uploads/DSC003.jpg>DSC003.jpg</a>
</tr>
</table>
But when I write that into the div it writes the a hrefs 1st followed by an empty table...
Any help is greatly appreciated.... struggling to do such simple things really gets me down
Your HTML is invalid.
An <a> element cannot be a child element of a <tr>.
Only <td> and <th> are allowed there.
The problem you are experiencing is likely the result of the browser attempting to recover from your error by moving the <a> elements to somewhere they are allowed (i.e. outside the table).
Write valid HTML instead. It looks like you don't have a tabular data structure so probably shouldn't be using a table in the first place. A list might be a better bet.
Like Quentin said, your HTML is invalid. <a> tags are allowed in <td> though.
Replace your PHP line of code with this one:
$returnValue .= '<tr><td><a href ="/uploads/' . $upload . '>' . $upload . '</a></td></tr>';
I just have a quick question how do I delete the item I just clicked? I don't have a great way of tracking it and I'm at my last resort way right now (which is what I'm posting) which deletes everything in the list.
PHP/HTML/jQuery:
<div class="image-list">
<?php
$count = 1;
if ($hotelId) {
foreach(glob($hotelDir) as $filename=>$hotelvalue){
echo '<li id="del'.$count.'" class="image-list"><a class="enlargeUser" href="'.$hotelvalue.'"><img class="imageListMain" src="'.$hotelvalue.'" width="50px" height="50px"/><p class="filename">' . basename($hotelvalue) . '</p></a> <a class="btn btn-mini btn-primary image-list" style="width: 18px;margin-top: -35px;position: relative\9;top: -25px\9;border-radius: 100%;-moz-border-radius: 100%;-o-border-radius: 100%;-webkit-border-radius: 100%;margin-left:330px;" id="del'.$count.'" value="Delete"><i class="icon-remove-circle icon-2" style="margin-left:-3px;"></i></a></li>' . "\n" . "<br>";
$count++;
}
}else{}
?>
</div>
</div>
<script>
$('div.image-list li a.image-list').live('click', function() {
bootbox.confirm("Are you sure you want to delete this image?", "Cancel", "Confirm", function(result) {
if (result) {
$('ul.image-list li a.image-list').closest('li').fadeOut();
$.post('assets/php/deletefile.php');
}
});
});
</script>
Here is the delete information (right now it is static PHP that only deletes the first file I don't have another way of doing this yet):
<?php
session_start();
$files = glob("upload/" . $_SESSION['curHotelId'] . "/" . '*.*');
if(is_file($files[0]))
#unlink($files[0]);
?>
UPDATE:
Thanks to Karl's answer I got a better idea of what I'm doing, but I still cannot get these to remove. I don't know why. They stay blank and act as if they don't even exist or the button does not work.
Here is my updated PHP/HTML/jQuery:
<div class="image-list">
<?php
$count = 1;
if ($hotelId) {
foreach(glob($hotelDir) as $filename=>$hotelvalue){
echo '<li data-filename="' . basename($hotelvalue) . '" id="del'.$count.'" class="image-list"><a class="enlargeUser" href="'.$hotelvalue.'"><img class="imageListMain" data-filename="' . basename($hotelvalue) . '" src="'.$hotelvalue.'" width="50px" height="50px"/><p class="filename">' . basename($hotelvalue) . '</p></a> <a data-filename="' . basename($hotelvalue) . '" class="btn btn-mini btn-primary image-list" style="width: 18px;margin-top: -35px;position: relative\9;top: -25px\9;border-radius: 100%;-moz-border-radius: 100%;-o-border-radius: 100%;-webkit-border-radius: 100%;margin-left:330px;" id="del'.$count.'" value="Delete"><i class="icon-remove-circle icon-2" style="margin-left:-3px;"></i></a></li>' . "\n" . "<br>";
$count++;
}
}else{}
?>
</div>
</div>
<script>
$('li.image-list a.image-list').click( function () {
var filename = $(this).attr('data-filename');
$(this).remove();
$.get('assets/php/deletefile.php?filename=' + filename).done( function() {
// it succeeded
}).fail( function (){
// it failed
});
});
});
</script>
And the PHP was updated too:
<?php
session_start();
$filename = $_get['filename'];
$files = glob("upload/" . $_SESSION['curHotelId'] . "/" . $filename);
if(is_file($files))
#unlink($files);
?>
HOPEFULLY FINAL UPDATE:
I'm so close, I just wanna throw everything I love out a window. So here is where I'm having an issue. It isn't deleting the images when the code executes so here is PHP:
ALL OF THIS CODE WORKS. C: Thank you everyone that helped!
<?php
session_start();
$file = $_POST['filename'];
$selHotelId = $_SESSION['curHotelId'];
$files = "upload/" . $selHotelId . "/" . $file;
unlink($files);
?>
jQuery:
$(document).ready(function(){
$("#imageClick").live("click", "li.image-list a.image-list", function () {
var _clicked = $(this);
var _filename = _clicked.attr('data-filename');
_clicked.parents("li.image-list").fadeOut(function(){
$(this).empty().remove();
});
$.post('assets/php/deletefile.php', {filename: _filename}).done( function(data) {
bootbox.alert('File has been deleted!');
}).fail( function (error){
bootbox.alert('There has been an error. Contact admin.');
});
});
});
There were still a few issues in your updated code. I've made some changes, and pasted in the code below. I've changed the method to $.post(), so your PHP file will need to access the parameter as $_POST['filename'].
A couple issues I noticed, you had more than one element with the same id attribute. I removed the redundant data-filename attributes from elements that didn't need them. I placed your jQuery inside a $(document).ready() in order to make sure that nothing was called until all DOM elements had been loaded. I also used the .on method for binding the event...just in case you ever dynamically add more li elements with the a.image-list element. This way you are binding the event to an element that will always be there, and catching it on the a.image-list. (I might be explaining that incorrectly...it's late).
Hope this helps.
<ul class="image-list">
<?php

$(this).empty().remove();
});
$.post('assets/php/deletefile.php', {filename: _filename}).done( function(data) {
// it succeeded
}).fail( function (error){
// it failed
});
});
})
</script>
UPDATE: I had a typo in my code...not sure you caught it.
var _filename = clicked.attr('data-filename');
SHOULD BE...
var _filename = _clicked.attr('data-filename');
My apologies.
To see if you are hitting your PHP file, you can do something simple like this...
<?php
$data["response"] = $_POST['filename'];
echo json_encode($data);
?>
And then modify your .done method to look like this...
$.post('assets/php/deletefile.php', {filename: _filename}).done( function(data) {
// it succeeded
console.log(data);
}).fail( function (error){
// it failed
});
You can delete or remove a DOM element with jQuery using a syntax similar to this and pull the value passed in your item:
$('div.image-list li a.image-list').click( function () {
var filename = $(this).attr('data-filename');
$(this).parents('li').remove();
});
You will have pass the data to the PHP file like you are doing but with the filename in the url:
$.get('assets/php/deletefile.php?filename=' + filename).done( function() {
// it succeeded
}).fail( function (){
// it failed
});
When you load the page you will have to load in the data-filename="filename.jpg" into the element you clicked.
In your deletefile.php, you can use $_GET['filename'] to get the filename.
I am having a little issue with the jquery autocoomplete plugin on my site. I have a search box that queries against a database for the usernames of registered users. This works great but one aspect. When the user clicks on the user to finish the search on the query, the results in the input text field show in HTML form which is and .
I want to only show the username they picked in the input box or just directly redirect them straight to the query page.
if this sounds confusing, this is the site and you can search without registering...
http://www.socialpurge.com/search_query.php
Below is some of the php which is the appended code for the search against the database
<?php
$input = $_POST['search'];
include($_SERVER['DOCUMENT_ROOT'] . "/scripts/members_connect.php");
$c_search = mysql_query("SELECT * FROM members WHERE fname LIKE '%$input%' or fullname LIKE '%$input%'");
while($rows = mysql_fetch_assoc($c_search)) {
$data = $rows['fullname'];
$fname = $rows['fname'];
$id = $rows['ID'];
/////// Mechanism to Display Pic. See if they have uploaded a pic or not //////////////////////////
$check_pic = "/members/$id/default.jpg";
$user_pic = print "<img src=\"$check_pic\" width=\"35px\" />"; // forces picture to be 100px wide and no more
print "<a href='profile.php?=&fname=" . $fname ."&user=" . $id . "'>" . $data . "</a>\n";
}
mysql_close($con);
?>
Below is the Javascript function that is calling the above php. This function is appended to the search form
<script>
$().ready(function() {
$("#search").autocomplete("include/user_search.php", {
width: 260,
matchContains: true,
selectFirst: false
});
});
</script>
If you do a quick search on the site, you will see what I am talking about. If anyone has any ideas that would be great. BTW I have tried changing the php a bit and still doesn't work. I am a little familiar with Javascript. I tried changing the source of the autocomplete.js plugin but that didn't work.
Is there a way to use Javascript/Jquery to remove the html tags and just keep text after selection and/or onclick event is triggered?
Please help me
Answer
Ofir Baruch was right, I just had to completely change the function I was using. I was using a seperate function plugin for Jquery. I updated Jquery I had and used the native one that was packaged inside the js file. This is what I did if it helps anyone.
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="js/jquery-ui-1.8.2.custom.min.js"></script>
<link rel="stylesheet" href="css/smoothness/jquery-ui-1.8.2.custom.css" />
<script>
$(document).ready(function() {
$("input#search").autocomplete({
source: 'include/user_search.php',
minLength: 1,
select: function(event, ui) {
var item = ui.item.value.replace(/(<([^>]+)>)/ig,"");
$('#search').val(item);
return false;
}
});
});
</script>
Then in my query file:
<?php
$input = $_REQUEST['term'];
include($_SERVER['DOCUMENT_ROOT'] . "/scripts/members_connect.php");
$c_search = mysql_query("SELECT * FROM members WHERE fname LIKE '%$input%' or fullname LIKE '%$input%'");
$data = array();
if ( $c_search && mysql_num_rows($c_search) )
{
while( $row = mysql_fetch_array($c_search, MYSQL_ASSOC) )
{
$check_pic = "/members/" . $row['ID'] . "/default.jpg";
$data[] = array(
'label' => "<img src='/members/" . $row['ID'] . "/default.jpg' width='35px' /><a href='profile.php?=&fname=" . $row['fname'] . "&user=" . $row['ID'] . "'>" . $row['fullname'] . "</a>"
);
}
}
// jQuery wants JSON data
echo json_encode($data);
flush();
mysql_close($con);
?>
Thanks again
Basicly , the php file should return a JSON string (DATA ONLY),
and the jquery script should handle the "design" of it , appending tags and such (img , a).
Anyway , the auto-complete jquery UI plugin has a select event.
select: function(event, ui) { ... }
Triggered when an item is selected from the menu; ui.item refers to
the selected item. The default action of select is to replace the text
field's value with the value of the selected item. Canceling this
event prevents the value from being updated, but does not prevent the
menu from closing
Therefore ,
$("#search").autocomplete("include/user_search.php", {
width: 260,
matchContains: true,
selectFirst: false,
select: function(event, ui) {
//use ui.item to manipulate the HTML code and to replace the field's
//value only with the user's name.
}
});
EDIT:
Your php file should return a JSON formated data , as mentioned.
Use an array variable in the next structre:
$results = array(
0 => array('id' => $ROW['id'] , 'name' => $ROW['name'] , 'fullname' => $ROW['full_name']),
....
....
);
use the php function: json_encode and echo it.
In your jquery , do something like:
function(data) {
$.each(data.items, function(i,item){
//use: item.id , item.name , item.full_name
$("#autocomplete-list").append("<img src='dir/to/image/"+item.id+".jpg>"+item.name);
});
How do I pass a variable in a php file that is loaded into a page (DOM) to a jQuery function??
Iv'e tried various method's while searching online but I haven't figured out how to use them correctly.
I need the var navHeaderTitle to be passes to the jQuery load() callback function so it sets the HTML tag, #navHeaderTitle, to the variable called in the php file.
Thnx for you help.
php:
<?php
$con = mysql_connect("localhost","user","pw");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("db", $con);
$result = mysql_query("SELECT * FROM some_list");
$navHeaderTitle = "MY NEW TITLE";//<--I NEED 2 INJECT THIS!!
while($row = mysql_fetch_array($result))
{
echo "<div id='navItem' title='$navHeaderTitle'>";
echo "<h1>" . $row['label'] . "</h1>";
echo "<h2>" . $row['title'] . "</h2>";
echo "<p>" . $row['description'] . "</p>";
echo "</div>";
}
mysql_close($con);
?>
JavaScript in the HTML Head:
<script type="text/javascript">
var navHeaderTitle = '';
$(document).ready(
function() {
$("#navContent").load('http://url/my_list.php', function() {
$('#navHeaderTitle').text($(html).find('div#navItem').attr('title'));//<--GET THE VAR FROM LOADED PHP FILE!!
});
});
</script>
<body>
<div id="navPanel">
<div id="navHeader">
<img src="images/ic_return.png" style="float: left;"/>
<img id="listSortBtn" src="images/ic_list_sort.png" style="float: right;"/>
<h4 id="navHeaderTitle"></h4>//THIS IS WHAT NEEDS THE VAR DATA!!
</div>
<div id="navScrollContainer" class="navContentPosition">
<div id="navContent">HTML CONTENT from PHP GETS DUMPED IN HERE</div>
</div>
</div>
</body>
Ive tried using this but not sure how to:
$.get('scripts/my_list.php', {}, function(data){
data = split(':');
})
I would have the php file return a json object that contains two parts, the html you want to echo and the title you want to use.
Then I would use jQuery's .ajax() function instead of .load() to get the return value from your php script in a javascript variable instead of dumping it directly as .load() does.
replace echo("$navHeaderTitle"); with
echo("<script> var navHeaderTitle = $navHeaderTitle </script>");
and remove var navHeaderTitle = ''; from the <head> script..
that will setup a JS variable like you're using, but you have to do that before the code in the <head> loads...
EDIT
ok don't echo("$navHeaderTitle"); you can put it into the HTML like:
echo "<div id='navItem' title='$navHeaderTitle'>";
then in the JS you can do:
<script type="text/javascript">
var navHeaderTitle = '';
$(document).ready(
function() {
$("#navContent").load('http://url/my_list.php', function(response) {
$('#navHeaderTitle').text($(response).attr('title'));
});
});
</script>
here's a jsfiddle demo: http://jsfiddle.net/JKirchartz/hdBzF/ (it's using fiddle's /echo/html/ so the load has some extra stuff to emulate the ajax)
It would be cleaner to pass the var in a custom attribute (data-var), then fetch it width JQuery
$(some_element).attr("data-var");
I hate to mess my JS code with php.
I am scraping sites, and I am doing this one at a time, and then trying to get the results to display AS I get them. I am trying to render one TR at a time, but instead, it does every single one, and then renders ALL the TRs.
Here is the call to javascript:
<body onload="getOffers(companies , {$scraped}, {$isbn13});">
Here is the JS/Jquery function:
function getOffers($company_ids, $scraped, $isbn)
{
if($scraped)
{
$.ajaxSetup({cache: false});
for(var $id in $company_ids)
{
$.ajax({
url: "../get_offer.php",
data: "id=" + $company_ids[$id] + "&isbn=" + $isbn + "&code=" + $id,
dataType: "html",
success: function(data) {
$("#results tbody:last").append(data);
}
});
}
}
else
{
return true;
}
}
And here is the PHP page:
<?php
require_once 'scrape.php';
require_once 'include.php';
$id = requestValue('id');
$isbn = requestValue('isbn');
$code = requestValue('code');
$page = curlMultiRequest(isbn10($isbn), $id);
$offer = getOffer($code, $page[$code], isbn10($isbn));
print "<tr><td>". $offer['company']."</td><td>". $offer['offer_new'] . "</td><td>" . $offer['offer_used']."</td></tr>";
?>
I tried returning the sting I am printing, but that didn't even work. How can I make it print each table row to the screen as the data is retrieved?
EDIT: so I tried adding this:
print "<tr><td>". $offer['company']."</td><td>". $offer['offer_new'] . "</td><td>" . $offer['offer_used']."</td></tr>";
ob_flush();
flush();
To the PHP and it didn't work. I don't understand, if I throw an alert, it happens on the fly for every ID, but the html rendering does not.
It may have magically fixed itself because your browser was caching some of the javascript. You should use some developer tools to manually flush the cache of resources for the host you are testing on to avoid old code being subtly used ....
