Passing a variable from jquery to php - php

Question

I am trying to pass a variable from jquery to php
My jquery code:
<script>
$(window).load(function(){
$.get("as.php",url="http://www.wired.co.uk/news/archive/2013-01/10/chinese-desert-mystery", function(data,status){
$('#lax').html(data);
});
});
</script>
<div id="lax" >
</div>
And my "as.php" file is as follows:
<?php
include('phpQuery.php');
$file = mysqli_real_escape_string($dbc, strip_tags(trim($_GET['url'])));
phpQuery::newDocumentFileHTML($file);
$titleElement = pq('title');
$title = $titleElement->html();
echo '<a href="" >' . htmlentities( $title) . '</a><br/>';
foreach(pq('meta') as $li)
if ((pq($li)->attr('name')=='description')||(pq($li)->attr('name')=='Description')){
echo '<p>'.pq($li)->attr('content').'</p>';
}
?>
I am tryin to pass 'url' variable from jquery code to my "as.php" file , but not able to do so. Where must be I going wrong?

Answer 1

You need to create an object
url="http://www.wired.co.uk/news/archive/2013-01/10/chinese-desert-mystery"
Should be:
{url :"http://www.wired.co.uk/news/archive/2013-01/10/chinese-desert-mystery"}
jQuery docs

Answer 2

I don't see you opening a database connection, so with the code you posted $dbc will be NULL.
That causes mysqli_real_escape_string to return NULL as well.
As you are not doing any database operations, you should get rid of mysqli_real_escape_string completely.

in you jquery:
<script>
$(window).load(function(){
$.get("as.php",
{url:"http://www.wired.co.uk/news/archive/2013-01/10/chinese-desert-mystery"}, function(data){
$('#lax').html(data);
});
});
</script>
in your php try using $_REQUEST
<?php
include('phpQuery.php');
$file = mysqli_real_escape_string($dbc, strip_tags(trim($_REQUEST['url'])));
phpQuery::newDocumentFileHTML($file);
$titleElement = pq('title');
$title = $titleElement->html();
echo '<a href="" >' . htmlentities( $title) . '</a><br/>';
foreach(pq('meta') as $li)
if ((pq($li)->attr('name')=='description')||(pq($li)->attr('name')=='Description')){
echo '<p>'.pq($li)->attr('content').'</p>';
}
?>
