this is actually a part of huge project so i didnt include the css but im willing to post it here if actually necessary.
Ok i have this code
<html>
<head>
<script src="js/jquery.js"></script>
<script type="text/javascript">
var q = "0";
function rr()
{
var q = "1";
var ddxz = document.getElementById('inputbox').value;
if (ddxz === "")
{
alert ('Search box is empty, please fill before you hit the go button.');
}
else
{
$.post('search.php', { name : $('#inputbox').val()}, function(output) {
$('#searchpage').html(output).show();
});
var t=setTimeout("alertMsg()",500);
}
}
function alertMsg()
{
$('#de').hide();
$('#searchpage').show();
}
// searchbox functions ( clear & unclear )
function clickclear(thisfield, defaulttext) {
if (thisfield.value == defaulttext) {
thisfield.value = "";
}
}
function clickrecall(thisfield, defaulttext) {
if (q === "0"){
if (thisfield.value == "") {
thisfield.value = defaulttext;
}}
else
{
}
}
//When you click on a link with class of poplight and the href starts with a #
$('a.poplight[href^=#]').click(function() {
var q = "0";
$.post('tt.php', { name : $(this).attr('id') }, function(output) {
$('#pxpxx').html(output).show();
});
var popID = $(this).attr('rel'); //Get Popup Name
var popURL = $(this).attr('href'); //Get Popup href to define size
//Pull Query & Variables from href URL
var query= popURL.split('?');
var dim= query[1].split('&');
var popWidth = dim[0].split('=')[1]; //Gets the first query string value
//Fade in the Popup and add close button
$('#' + popID).fadeIn().css({ 'width': Number( popWidth ) }).prepend('<img src="images/close_pop.png" class="btn_close" title="Close Window" alt="Close" />');
//Define margin for center alignment (vertical + horizontal) - we add 80 to the height/width to accomodate for the padding + border width defined in the css
var popMargTop = ($('#' + popID).height() + 80) / 2;
var popMargLeft = ($('#' + popID).width() + 80) / 2;
//Apply Margin to Popup
$('#' + popID).css({
'margin-top' : -popMargTop,
'margin-left' : -popMargLeft
});
//Fade in Background
$('body').append('<div id="fade"></div>'); //Add the fade layer to bottom of the body tag.
$('#fade').css({'filter' : 'alpha(opacity=80)'}).fadeIn(); //Fade in the fade layer
return false;
});
//Close Popups and Fade Layer
$('a.close, #fade').live('click', function() { //When clicking on the close or fade layer...
$('#fade , .popup_block').fadeOut(function() {
$('#fade, a.close').remove();
}); //fade them both out
return false;
});
});
</script>
</head>
<body>
<input name="searchinput" value="search item here..." type="text" id="inputbox" onclick="clickclear(this, 'search item here...')" onblur="clickrecall(this,'search item here...')"/><button id="submit" onclick="rr()"></button>
<div id="searchpage"></div>
<div id="backgroundPopup"></div>
<div id="popup" class="popup_block">
<div id="pxpxx"></div>
</div>
</body>
</html>
Ok here is the php file(search.php) where the jquery function"function rr()" will pass the data from the input field(#inputbox) once the user click the button(#submit) and then the php file(search.php) will process the data and check if theres a record on the mysql that was match on the data that the jquery has pass and so if there is then the search.php will pass data back to the jquery function and then that jquery function will output the data into the specified div(#searchpage).
<?
if(isset($_POST['name']))
{
$name = mysql_real_escape_string($_POST['name']);
$con=mysql_connect("localhost", "root", "");
if(!$con)
{
die ('could not connect' . mysql_error());
}
mysql_select_db("juliver", $con);
$result = mysql_query("SELECT * FROM items WHERE title='$name' OR description='$name' OR type='$name'");
$vv = "";
while($row = mysql_fetch_array($result))
{
$vv .= "<div id='itemdiv2' class='gradient'>";
$vv .= "<div id='imgc'>".'<img src="Images/media/'.$row['name'].'" />'."<br/>";
$vv .= "<a href='#?w=700' id='".$row['id']."' rel='popup' class='poplight'>View full</a>"."</div>";
$vv .= "<div id='pdiva'>"."<p id='ittitle'>".$row['title']."</p>";
$vv .= "<p id='itdes'>".$row['description']."</p>";
$vv .= "<a href='http://".$row['link']."'>".$row['link']."</a>";
$vv .= "</div>"."</div>";
}
echo $vv;
mysql_close($con);
}
else
{
echo "Yay! There's an error occured upon checking your request";
}
?>
and here is the php file(tt.php) where the jquery a.poplight click function will pass the data and then as like the function of the first php file(search.php) it will look for data's match on the mysql and then pass it back to the jquery and then the jquery will output the file to the specified div(#popup) and once it was outputted to the specified div(#popup), then the div(#popup) will show like a popup box (this is absolutely a popup box actually).
<?
//session_start(); start up your PHP session!//
if(isset($_POST['name']))
{
$name = mysql_real_escape_string($_POST['name']);
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("juliver", $con);
$result = mysql_query("SELECT * FROM items WHERE id='$name'");
while($row = mysql_fetch_array($result))
{
$ss = "<table border='0' align='left' cellpadding='3' cellspacing='1'><tr><td>";
$ss .= '<img class="ddx" src="Images/media/'.$row['name'].'" />'."</td>";
$ss .= "<td>"."<table><tr><td style='color:#666; padding-right:15px;'>Name</td><td style='color:#0068AE'>".$row['title']."</td></tr>";
$ss .= "<tr><td style='color:#666; padding-right:15px;'>Description</td> <td>".$row['description']."</td></tr>";
$ss .= "<tr><td style='color:#666; padding-right:15px;'>Link</td><td><a href='".$row['link']."'>".$row['link']."</a></td></tr>";
$ss .= "</td></tr></table>";
}
echo $ss;
mysql_close($con);
}
?>
here is the problem, the popup box(.popup_block) is not showing and so the data from the php file(tt.php) that the jquery has been outputted to that div(.popup_block) (will if ever it was successfully pass from the php file into the jquery and outputted by the jquery).
Some of my codes that rely on this is actually working and that pop up box is actually showing, just this part, its not showing and theres no data from the php file which was the jquery function should output it to that div(.popup_block)
hope someone could help, thanks in advance, anyway im open for any suggestions and recommendation.

First thought, the script is being called before the page is loaded. To solve this, use:
$(document).ready(function()
{
$(window).load(function()
{
//type here your jQuery
});
});
This will cause the script to wait for the whole page to load, including all content and images
if you're using ajax to exchange data into a php file. then check your ajax function if its actually receive the return data from your php file.

I do not think invoking autoload_process.php from jquery is the best way how to load files in Zend2. I think I should somehow call my Controller or my table functions, but no luck yet.
I'm using jquery ,ajax and php to implementing infinite scrolling

I really nead a help
You see to be setting the variables wrong from a quick look:
var actual_count = "<?php echo $actual_row_count; ?>";
You're using mysql_num_rows() to count the return on your first set of results. But that is limited to 12.
You need to do a second mysql query to get all the images without limi, then count them to get the total number of images in the database.
In index.php your query is only returning 12 rows meaning that $actual_row_count is only ever going to be 12. Instead I would set $actual_row_count to the result of the query "SELECT count
(*) FROM photo".
My personal preference for these sort of things is to return a JSON response which only contains the n responses that are loading and have a template html stored in javascript. The way you've written it will return all the photo's on the last query instead of the last 12 that you want.
I Have to delay my redirection by few seconds. When I try to do this It is not working. I have attached my Javascript and php below. can anyone please help me to solve the problem.window location not working.
<script type="text/javascript">

The first parameter of setTimeout should be a function. Try wrapping it with an anonymous function like so:
setTimeout(function() {
window.location = string_url
}, 5000);
try this:
`setTimeout("createCustomAlert(txt);", 3000);`

i'm having 2 pages. An index page connected to a js file. This js file containing ajax code fetching data from database.
this is my js file
$(document).ready(function() {
// getting links from db andshow sub_menu div //
$(".menu_item").mouseover(function(){
$(this).addClass("selected").children().slideDown(500,function(){
var id = $(".selected").attr("id");
var ajax= false;
ajax = new XMLHttpRequest();
var qst = "?id="+id;
ajax.open("GET","ajax/get_sub_cats.php"+qst);
ajax.onreadystatechange = function(){
if(ajax.readyState == 4 && ajax.status == 200){
$(".sub_menu[title="+id+"]").html(ajax.responseText);
}
}
ajax.send(null);
});
});
// hiding sub_menu div //
$(".menu_item").mouseout(function(){
$(this).removeClass("selected").children(".sub_menu").slideUp(500);
});
// keeping sub_menu div visible on mouse over //
$(".sub_menu").mouseover(function() {
$(this).stop();
});
// clicking sub menu link in the menu //
$(document).delegate("a#subCatLink","click",function(){
alert("test");
});
// document ready end
});
and this is get_sub_cats php file used to fetch links from db
<?php
require('../_req/base.php');
$id = $_REQUEST['id'];
$getSubcatsQ = "select * from sub_cats where Main_Cat_ID = '$id'";
$getSubcatsR = mysql_query($getSubcatsQ);
$numrows = mysql_num_rows($getSubcatsR);
while($row = mysql_fetch_array($getSubcatsR)){
?>
<a id="subCatLink" href="products.php?id=<?php echo $row['Sub_Cat_ID']; ?>"><?php echo $row['Sub_Cat_Name']; ?></a><br />
<?php
}
mysql_close($connect);
?>
clicking links coming from the other php file using ajax is not working at all
Sorry, maybe this will help, maybe not. But...
Why don't you use something like this:
jQuery
$(".menu_item").mouseover(function(){
var id = $(".selected").attr("id");
var qst = "?id="+id;
var html = '';
$.getJSON('ajax/get_sub_cats.php'+qst, function(data){
var len = data.length;
for (var i = 0; i< len; i++) {
html += '<a id="subCatLink'+data[i].Sub_Cat_ID+'" href="products.php?id='+data[i].Sub_Cat_ID+'">'+data[i].Sub_Cat_Name+'</a>';
}
$(".sub_menu[id="+id+"]").html(html);
});
});
PHP
require('../_req/base.php');
$return = array();
$id = $_REQUEST['id'];
$sql = "select * from sub_cats where Main_Cat_ID = '$id'";
$result = mysql_query($sql);
while($ln = mysql_fetch_array($result)){
$return[] = $ln;
}
echo json_encode($return);
ok try this
$(document).delegate("click","a",function(){
var target = $(this).attr("href");
alert(target);
});
That should, as a test, show the href for every link on your page. If that works, put all the links you want to show in a div. Then call it with
$('#divID').delegate("click","a",function(){
var target = $(this).attr("href");
alert(target);
})
I have some code that involves clicking on a button and either you are logged in and you go to the next page or you are logged out and you get an alert. I have never liked onClick inside HTML and so I would like to turn this around into clicking on the id and having the jQuery do its magic.
I understand the click function of jQuery, but I don't know how to put do_bid(".$val["id"]."); down with the rest of the Javascript. If I haven't given enough information or if there is an official resource for this then let me know.
<li class='btn bid' onclick='do_bid(".$val["id"].");'> Bid </li>
<script>
//Some other Javascript above this
function do_bid(aid)
{
var loged_in = "<?= $_SESSION["BPLowbidAuction_LOGGED_IN"] ?>";
if(loged_in=="")
{
alert('You must log in to bid!');
}
else
{
document.location.href="item.php?id="+aid;
}
}
</script>
UPDATE: This is the entirety of the Javascript code. I think none of the answers have worked so far because the answers don't fit the rest of my Javascript. I hope this helps

If you want to attach click event handler using jQuery. You need to first include jQuery library into your page and then try the below code.
You should not have 2 class attributes in an element. Move both btn and bid class into one class attribute.
Markup change. Here I am rendering the session variable into a data attribute to be used later inside the click event handler using jQuery data method.
PHP/HTML:
echo "<li class='btn bid' data-bid='".$val["id"]."'>Bid</li>";
JS:
$('.btn.bid').click(function(){
do_bid($(this).data('bid'));
});
If you don't want to use data attribute and render the id into a JS variable then you can use the below code.
var loged_in = "<?= $_SESSION["BPLowbidAuction_LOGGED_IN"] ?>";
$('.btn.bid').click(function(){
if(!loged_in){
alert('You must log in to bid!');
}
else{
do_bid(loged_in);
}
});
First, you need to make the <li> have the data you need to send, which I would recommend using the data attributes. For example:
echo "<li class=\"btn bid\" data-bid=\"{$val['id']}\">Bid</li>";
Next, you need to bind the click and have it call the javascript method do_bid which can be done using:
function do_bid(bid){
//bid code
}
$(function(){
// when you click on the LI
$('li.btn.bid').click(function(){
// grab the ID we're bidding on
var bid = $(this).data('bid');
// then call the function with the parameter
window.do_bid(bid);
});
});
Assuming that you have multiple of these buttons, you could use the data attribute to store the ID:
<li class='btn' class='bid' data-id='<?php echo $val["id"]; ?>'>
jQuery:
var clicked_id = $(this).data('id'); // assuming this is the element that is clicked on
I would add the id value your trying to append as a data attribute:
Something like:
<li class='btn' class='bid' data-id='.$val["id"].'>
Then bind the event like this:
$('.bid').click(function(){
var dataId = $(this).attr('data-id');
doBid(dataId);
});
You can store the Id in a data- attribute, then use jQuery's .click method.
<li class='btn' class='bid' data-id='".$val["id"]."'>
Bid
</li>
<script>
$(document).ready(function(){
$("li.bid").click(function(){
if ("" === "<?= $_SESSION["BPLowbidAuction_LOGGED_IN"] ?>") {
alert('You must log in to bid!');
}
else {
document.location.href="item.php?id=" + $(this).data("id");
}
});
});
</script>
If you are still searching for an answer to this, I put a workaround.
If data is not working for you, try the html id.
A working example is here: http://jsfiddle.net/aVLk9/
