I am writing an application in JQTouch, and am using a big red button
Red
I am using PHP to dynamically build the JQT page with multiple divs. The app is a server management console that gets data from MySQL. My idea is that I use a While loop to make a div for each server returned in the MySQL query, and each div will have a delete server button(the big red button). I have to call the dame bit of code because of the whole dynamic page generating thing. So I was wondering if there was a way I could have the onClick function that I call with the button
Red
know what div the button is in that is calling the function. There will be a button in multiple divs that call the same code, but i have to know WHAT server to delete. Any suggestions?
Here is the full source code.

add a data attribute to your "Big Red Button" as follows
Red
and from your handling code retrieve the data value as follows
var server = $(this).attr('data-server');
Then you can do your condition logic.
DevZer0's answer is probably what you want to go with but an alternative approach is to add a class to the containing div like
echo '<div id="'.$friendlyName_noSpaces2.'" class="server">';
Then you can do this in your callback
var server = $(this).closest(".server").attr("id");
to get the id of the containing div.

I have a download page. Members are free to click on their bought songs and the download starts. I wish now that in the same time an Ajax request takes place, which adjusts the count of downloads in the database. The page should then be reloaded to the counter from the database is updated again. If the counter is zero, there is no longer downloading.
Obviously my script does not work. The download happens, but the JQuery-Script will not work. Does someone have a solution?
This is the link to the download-page:
<a href="get-download-files.php?file=xyz.zip"><img class="a_0" src="images/download.png" width="30" height="30" />XYZ-Song/a>
And this is the Java-Script on the same page:
<script>
$(document).ready(function(){
$(".a_0").click(function(){
$.get("zaehler.php?dl_id=1", function(data){
$("#ausgabe").html(data);
});
});
});
</script>
And this is the request-file:
<?php
require_once 'includes/db_login.php';
$dl_id = $_REQUEST['dl_id'];
// counter updaten
$sql = 'UPDATE ' . $tbl_prefix . 'downloads
SET zaehler = zaehler - 1
WHERE dl_id = ' .$dl_id;
mysql_query($sql);
$abfrage = 'SELECT zaehler FROM ' . $tbl_prefix . 'downloads WHERE dl_id=' . $dl_id;
$ergebnis = mysql_query($abfrage);
while ($datensatz = mysql_fetch_array($ergebnis, MYSQL_ASSOC))
{
echo '<h3 style="color:#333;">Dein Download-Stand</h2>';
echo '<br /><br />Du hast noch ' . $datensatz['zaehler'] . ' Downloads zugut.';
}
?>
Im thanking you. Best regards,
Heinz
You don't need Ajax for this. In the script get-download-files.php, update the database before delivering the file to the browser.
Have you tried this?
<script>
$(document).ready(function(){
$(".a_0").click(function(){
$("#ausgabe").load("zaehler.php?dl_id=1");
});
});
</script>
You can check if your code is executed by adding a alert() inside your function. If the alert fires, the function is executed.
<script>
$(document).ready(function(){
$(".a_0").click(function(){
alert('Function is fired!'); // Debug
$("#ausgabe").load("zaehler.php?dl_id=1");
});
});
</script>
I have a comics website which loops through all images in a db and displays them as thumbnails.
The user can click on one of those images to see it in normal size on a viewComic.php template.
I'd like to allow users to press left and right arrows to navigate images.
So, my idea is:
pagination.php handles image display on correct pages (by offsetting) by looping through database result array. The user can click on a result (below) to go to that specific image on the viewcomic.php template.
'<br />IMG: <a href="./templates/viewcomic.php?id=' . $row['imgid'] . '&image=' . $imgpath.$row['imgname'] . '">
Now on viewcomic.php, I get the id and image, and display the image
$imgid = $_GET['id'];
$imgpath = $_GET['image'];
<center><img src=".<?php echo $imgpath ?>" /></center>
The user can press left and right arrows to navigate through images...
My goal was to somehow increment the image id to move to the next image, but that doesn't seem to be working...
<script type="text/javascript">
$(document).ready(function() {
$(document).keydown(function (e) {
if (e.which == 39) { //get next image
<?php
$count = 0;
$count++;
echo "<img src=" . $imageArray[$count] . "/>";
?>
}
});
});
</script>
Any ideas?
EDIT: I'm going to go through an image array passed in from pagination.php.
So, in my viewcomic.php file, I've updated my jquery script (see above).. but the jquery doesn't seem to like the embedded php, even though it's all in a php file.
Here's a picture of page source vs code:
Here is what i would do:
assuming that an imagepath is surrounded by quotes:
echo $imageArray[0]; // 'imagepath/image'
Script:
<script type="text/javascript">
var imgArray = [<?php echo implode(',',$imageArray) ?>];
// now the image array have the list of all your images.
$(document).ready(function() {
var img = document.getElementById("theImage");
imgIndex = 0;
$(document).keydown(function (e) {
if (e.which == 39) { //get next image
img.src = imgArray[imgIndex++]
}
... /* Logic to check if at the end of imageArray */ ...
});
});
</script>
The Html:
<center><img src="" id="theImage"/></center>
How about:
$(document).ready(function() {
$(document).keydown(function (e) {
if (e.which == 39) {
var nextId = $_GET['id'] + 1;
window.location = "./templates/viewcomic.php?id=" + nextId;
}
});
});
In this case your page is submit on every request, You can also handle this at client site.

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'm creating a simple slideshow. 4 images coming from db by php stored in a div called home_gallery_thumb with relative position and the images are wrapped inside anchor tag trying to change them with a next and previous buttons but it jumps to the third image then everything stops completely though it works without any problem if these images are static not coming from the db here's the div fetching images
<div class="home_gallery_thumb" style="background-color:#006; position:relative;">
<?php
require('_req/base.php');
$getImgsQ = "select Photo_Name from photos order by Photo_ID DESC limit 4";
$getImgsR = mysql_query($getImgsQ);
while($galleryRow = mysql_fetch_array($getImgsR)){
?> <a class="galleryLink" style="position:absolute;" href="products_large/<?php echo $galleryRow['Photo_Name']; ?>"><img src="products_thumb/<?php echo $galleryRow['Photo_Name']; ?>" /></a> <?php
}
mysql_close($connect);
?>
so now i have links with images inside the div and here's the jq code
$(".home_gallery_thumb a.galleryLink").css("display","none");
$("a.galleryLink:first").fadeIn(500);
var allImgs = $(".home_gallery_thumb a").length;
$(".next").click(function(){
var curImg = $("a.galleryLink:visible").index();
var nxtImg = curImg+1 ;
if(nxtImg == allImgs) { nxtImg = 0; }
$("a.galleryLink:eq("+curImg+")").fadeOut(800,function(){
$("a.galleryLink:eq("+nxtImg+")").fadeIn(800);
});
});
$(".previous").click(function(){
var curImg = $("a.galleryLink:visible").index();
var prevImg = curImg-1 ;
if(prevImg == -1) { prevImg = allImgs-1; }
$("a.galleryLink:eq("+curImg+")").fadeOut(800,function(){
$("a.galleryLink:eq("+prevImg+")").fadeIn(800);
});
});
this code is inside document.ready and that's what i noticed through firebug
first : images load and all other links are : display:none
after clicking next button first link doesn't get display:none style and it jumps to the third link making it visible then everything stops. And the previous button does nothing at all as it doesn't exist
try this, if not work, provide a link to your slide
$("a.galleryLink").hide();
$("a.galleryLink:first-child").fadeIn(500);
$(".next").click(function(){
var curImg = $("a.galleryLink:visible");
var nxtImg = curImg.next();
if(!nxtImg.length) { nxtImg = $("a.galleryLink:first-child"); }
curImg.fadeOut(800,function(){
nxtImg.fadeIn();
});
});
$(".previous").click(function(){
var curImg = $("a.galleryLink:visible");
var prvImg = curImg.prev();
if(!prvImg.length) { prvImg = $("a.galleryLink:last-child"); }
curImg.fadeOut(800,function(){
prvImg.fadeIn();
});
});
