Using Ajax to Post PHP variables to another file
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 ty开发者_JAVA百科pe='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.
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"
});
});
});
加载中,请稍侯......
