I currently have a problem with php and javascript. Here is the thing : I'm trying to edit every few second a text file stored on the server, with the text the client wrote in a textarea (which id is 'area1')
The PHP :
<span id="write">
<?php
if(isset($_POST['text']))
{
file_put_contents('file.txt', $_POST['text']);
}
?>
</span>
The Javascript :
window.onload = function(){
t = setInterval(load, 2000);
function load()
{
$.ajax({
type: "POST",
url: "test.php",
data: {
text: $('#area1').val()
},
dataType: "text",
success: function(data) {
$('#write').load('test.php #write');
}
});
}
}
Nevertheless, nothing is ever written in file.txt, even if we enter the isset condition (that I tested).
Why isn't it working ? Can't we use jquery load with file_put_contents ? Or maybe it is a silly mistake that I can't see...
Thank you !

Have you tried using $.post? It is simpler and clearer. Below is the full working code.
<html>
<head>
<script src="//code.jquery.com/jquery-2.1.4.min.js"></script>
</head>
<body>
<form>
<textarea id="area1"></textarea>
<textarea id="write"></textarea>
</form>
<script>
$(document).ready(function(){
t = setInterval(load, 2000);
function load()
{
$.post( "test.php", { text: $('#area1').val() })
.done(function( data ) {
$('#write').load('test.php #write');
});
}
});
</script>
</body>
</html>
And also make sure your php script has a privilege to add files.
Use (sudo) chown apache *folder* or similar.
Good luck!
