Using Ajax to Post PHP variables to another file

Question

I want to post the PHP variables $uid and $submissionid to the file fblike.php. Is the Ajax below formatted correctly to do this?

<?php


ob_start();
session_start();

$uid = $_SESSION['loginid'];

$submissionid = mysql_real_escape_string($_GET['submissionid']);
$_SESSION['submissionid'] = $submissionid;


?>


<head>


<script type='text/javascript' src='jquery.pack.js'></script>
<script type='text/javascript'>
$(function(){
    $("a.connect_widget_like_button").live(function(){

        $.ajax({
            type: "POST",
            data: "action=vote_up&uid="+$(this).attr("uid")"&submissionid="+$(this).attr("submissionid"),
            url: "fblike.php",

        });
    });


}); 
</script>

</head>

You dont really want to use expando attributes if you dont have to, especially since thise are links... i would jsut do:

<a href="fblike.php?ction=vote_up&uid=1&&submissionid=1">Like</a>

then you can do a simple:

$("a.connect_widget_like_button").live('click', function(e){
   e.preventDefault();
   $.post($(this).attr('href'));
});

Now on the php side you need to be aware of where the values will be. If you pass the values as i have done in my example they will be in $_GET (even if its a POST request). If you pass them like you did in your original post then they will be in $_POST.

Thanks... I didn't use your exact solution but putting the URL in the href with the Facebook Like button led me down the right path.

You need to send the data as an array/object. Something like this should do the trick.

$(function(){
    $("a.connect_widget_like_button").live(function(){

        $.ajax({
            type: "POST",
            data: {
                action: "vote_up",
                uid: $(this).attr('uid'),
                submissionid: $(this).attr('submissionid')
            },
            url: "fblike.php"
        });
    });
});

While passing data as a hash is much easier to read (and i also prefer it) using a query string will work.
