Jquery.post() sends variables, but PHP shows them empty?

I'm working on a script right now for a simple shout box. I was using $.get() before without any issues. I then switched over to $.post() so I can pass Cyrillic characters to php.

I switched over everything to post already in both the javascript and php files. Firebug shows that the variables are not empty and being sent and their is a standard response from the php script, but not the right one. I tried printing the whole $_POST varia开发者_StackOverflow中文版ble scope, but just gives an empty array. What am I doing wrong?

$.post('file.php', { sc_com:'submit', name:userboxVal, color:swatch, msg:escape(msgboxVal) }, function(data) {
    if(data.error) {
        msgbox.focus();
        shoutError(data.error);
    } else if(data.status=='posted') {
        msgbox.val('').focus();
        refreshShouts(opts,'ajax');
    }
}, 'json');

PHP

$sc_com = strip_tags($_POST['sc_com']); // Empty
print_r($_POST); // returns Array()

Not sure why you would need the PHP code for it? The whole thing is over 500 lines, but that is the most important part...

Try serializing the data before sending it to php? jquery $.post empty array
