Question

I am at a total loss with this, I need to create a “like button” like the facebook like button, I have tried to use jquery to do this but havent got anywhere. I need to basically add a row to a mysql db and then update the number of “likes” next to the button ont he page all without a refresh.

Can anyone help with this as I am totally stuck as i dont know javascript or jquery 🙁

Hope someone can as its been driving me nuts 🙂

This is the basics I think?

Your Button

<div id="likeMe">Like This</div>

Your call back div

<div style="display: none" class="addlike">loading...</div>

Your Javascript

<script type="text/javascript"> 
$("#likeMe").click(function() { 
$(".addlike").delay(10000).load("savelike.php?page_id=<?php echo $p;?>&user=<?php echo $user_id;?>&msd=" + new Date().getTime());  
});
</script>

Your php save page
savelike.php

$page_id = $_REQUEST["page_id"];
$user = $_REQUEST["user"];
$sql ="INSERT INTO MYLIKES SET user = '$user' && page_id = '$page_id'";
$query = mysql_query($sql) or die("Cannot query the database." . mysql_error());
