the Thread_id never gets printed.. no thread_id is set, even though, I did put it as a url parameter before sending it in the javascript code:
**if( isset($_GET["thread_id"]) )
{
echo 'Thread_id: '.$_GET["thread_id"];
**}**
Why isnt the trhead_id echoed out, when I click the button (when the xmlhttpRequest is being obtained?!?)**
Source:http://www.coursesweb.net/ajax/ajax-get-php
I want to to get $_Get..The question is whether I can send a request to my own page or I have to send a request with the Get parameters to another page...to make an echo!??!
<?php
// if data are received via GET, with index of 'test'
if (isset($_GET['test'])) {
$str = $_GET['test']; // get data
echo "The string '<i>".$str."</i>' contains ". strlen($str). ' characters and '. str_word_count($str, 0). ' words.';
}
?>
This code returns what I expected it to return. In the console it returns the whole page. I would suggest you read up on XHR and AJAX.
Probably a good place to start http://www.w3schools.com/ajax/default.asp
