Here my index.php page structure:
<?php
session_start();
include("lang/".$_SESSION['lang'].".php");
?>
<!DOCTYPE html>
<html lang="en">
<head>
...
</head>
<body>
<a href="#" data-module="home">
<div id="content"></div>
</body>
<script src="jquery.js"></script>
<script src="script.js"></script>
</html>
I have a piece of js code to load the right clicked module.
$('a[data-module]').click(function(event) {
event.preventDefault();
var module = $(this).attr('data-module');
$('#content').load('modules/' + module + '.php');
});
My problem is:
On each module page, I use $_SESSION variables. But with .load() jQuery function, it don't works anymore.
Do you have a reason for that ?
Thanks.

I am getting the issue
Warning: Use of undefined constant otherInput - assumed 'otherInput'
(this will throw an Error in a future version of PHP) Warning: A
non-numeric value encountered
I know there is some issue with the quote.
What I am doing is, I have to click on the anchor tag called Click me one and sending the data-id in the script. I am getting the id value in the script but I am getting the error on $(".showme'+otherInput+'").show();
I am using WordPress and I have to use the below code in the function.php so I have to use my script inside the PHP tag.
This is the screenshot of the code
Here is the code
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
.showme{display: none;}
</style>
</head>
<body>
<div class="clickme" data-id="1">Click me one</div>
<div class="showme showme1">this is example</div>
<?php
echo '<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script type="text/javascript">
$(".clickme").click(function(){
var otherInput=$(this).data("id");
$(".showme'+otherInput+'").show();
});.
</script>';
?>
</body>
</html>
It looks like everything in your php block is all JQuery/Javascript.
Q: What do you even need the PHP block and the "echo" for?
Current:
<?php
echo '<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script type="text/javascript">
$(".clickme").click(function(){
var otherInput=$(this).data("id");
$(".showme'+otherInput+'").show();
});.
</script>';
?>
Suggested change:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script type="text/javascript">
$(".clickme").click(function(){
var otherInput=$(this).data("id");
$(".showme"+otherInput).show();
});.
</script>'
Just follow the regular js standard, and if you willing to implement your script inside the php code:
Replace your code with these changes:
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
.showme{display: none;}
</style>
</head>
<body>
<div class="clickme" data-id="1">Click me one</div>
<div class="showme showme1">this is example</div>
<?php
echo '<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script type="text/javascript">
$(".clickme").click(function(){
var otherInput=$(this).data("id");
$(".showme"+otherInput).show();
//here otherInput js variable is just used as regular js variable inside the script, so no need to extra commas to call that js variable, just use it like you do in js files, and will work fine.
});
</script>';
?>
</body>
</html>
Probably I'm misunderstanding something about Fancybox v1 but have the following minor issue. First I'm calling fancybox via clicking a link:
$(document).ready(function() {
$(".href").click(function() {
$.fancybox.open({
href : $(this).attr("data-id"),
type : 'iframe'
});
});
});
This loads a simple PHP/HTML page with JS, to be populated into the Fancybox window:
<!DOCTYPE html><html><head><title></title></head>
<body>
<?php
# this is the fancybox content
echo "<script>var dcwrtext = 'random_text'; document.write(dcwrtext);</script> Some other content to show on fancybox.";
?>
</body></html>
The content appears without a problem, but the nuance is, the document.write value is echoed after the closing </script> tag: and this makes the content visible on the page, not the document.write() function. You can see this in the source code:
<body>
<script>var dcwrtext = 'random_text'; document.write(dcwrtext);</script>**random_text** Some other content to show on fancybox.
</body>
The problem seems to be with fancybox, if I use the document.write() on a standard HTML (not fancyboxed) page, as expected, it will correctly show 'random_text' on the page, inside <script></script> only. This is the source code:
<body>
<script>var dcwrtext = 'random_text'; document.write(dcwrtext);</script> Some other content to show on fancybox.
</body>
What I'd need is if I open the fancbox window, 'random_text' shouldn't appear literally after the closing </script> tag, but would be displayed only by the document.write() function.
This is how I tested:
main page:
<html>
<head>
<title></title>
<meta name="" content="">
<link rel="stylesheet" type="text/css" href="fancybox/source/jquery.fancybox.css?v=2.1.2" media="screen" />
</head>
<body>
<div data-id="fancy.php" class="href">open fancy</div>
<script src="http://code.jquery.com/jquery-1.9.0.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.js"></script>
<script type="text/javascript" src="fancybox/source/jquery.fancybox.js?v=2.1.3"></script>
<script>
$(document).ready(function() {
$(".fancybox").fancybox();
$(".href").click(function() {
$.fancybox.open({
href : $(this).attr("data-id"),
type : 'iframe'
});
});
});
</script>
<div id="theid" class="fancybox"></div>
</body>
</html>
and the page being opened in fancybox: fancy.php
<html>
<head>
<title></title>
</head>
<body>
<?php
$randomtext = "random_text";
echo "<script>var dcwrtext = '$randomtext'; document.write(dcwrtext);</script>Some other content to show on fancybox";
?>
</body>
</html>
[I had to include jquery-migrate-1.2.1.js because of an error [ Uncaught TypeError: Cannot read property 'msie' of undefined] when including newer versions of jquery with fancybox]
I thought this would be simple enough, but I can't get it to work.
I have two files. main.html and data.php
The two files are in the same folder on a server.
I want to get a string from the PHP file and use it in jQuery. In the example below, I want the browser to create a pop-up, with the text "xxxx". I get no pop-up.
data.php
<?php
$var = "xxxx";
echo json_encode($var);
?>
main.html
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="scripts/jquery-1.11.1.js"></script>
<script>
$(document).ready(function() {
var testString = <?php $var = json_decode(file_get_contents('data.php'), true); echo $var; ?>;
alert(testString);
});
</script>
</head>
<body>
<h1>Test</h1>
</body>
</html>
Any takers?
<!DOCTYPE html>
<html>
<head>
<script>
$(document).ready(function() {
$.ajax({
url:"data.php",
success:function(result){
alert(result);
}
});
});
</script>
</head>
<body>
<h1>Test</h1>
</body>
</html>
The first problem with this is that on many servers .html is not parsed for PHP
The second problem is that the file_get_contents will actually display the full contents of your .php file (including the <?php) which is likely not what you're looking for.
Instead I would use an AJAX request such as http://api.jquery.com/jquery.get/
For this you will need to include jQuery in your <head>
You should get the php data before html initiates, like below
<?php
$var = json_decode(file_get_contents('data.php'), true);
?>
<!DOCTYPE html>
<html>
<head>
<script>
$(document).ready(function() {
var testString = <?php echo $var; ?>;
alert(testString);
});
</script>
</head>
<body>
<h1>Test</h1>
</body>
</html>
Attempting to run fineuploader right out of the box using the same code that's on the site.
<!DOCTYPE html>
<html>

function createUploader() {
var uploader = new qq.FineUploader({
element: document.getElementById('fine-uploader'),
request: {
endpoint: 'server/handleUploads'
}
});
}
window.onload = createUploader;
</script>
</body>
</html>
Even before beginning to mess around with the endpoint.php I took a look at in a browser and I'm getting the following errors in Firebug:
ReferenceError: jQuery is not defined

What am I missing?
jQuery library is missing in your code
add this in your head tag
<head>
.
.
.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
.
.
</script>
</head>
I have index.html like this
<!DOCTYPE html>
<html lang="en">
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/
libs/jquery/1.3.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
var auto_refresh = setInterval(
function ()
{
//alert("abc");
$('#mydiv').load('xyz.php').fadeIn("slow");
}, 1000);
});
</script>
</head>
<body>
<div id="mydiv"> </div>
</body>
</html>
In same folder there is xyz.php file whose code is this:
<?php
echo "My first PHP script!";
?>
When I uncomment //alert("abc"); and comment $('#mydiv').load('xyz.php').fadeIn("slow");
alert message comes every second but vice versa is not working when I am calling php file and commenting alert message. Why?
It´s working for me, but you only can see the content one time, because .load function is replacing the old content, change
$('#mydiv').load('xyz.php').fadeIn("slow");
with this
$('#mydiv').append($('<div >').load('xyz.php'));
I renamed index.html to index.php and called that by localhost/firstproject/index.php. That worked
