So on my site a user as a "wall" where they can post status updates and other people can post a comment on their wall.
The issue is that the like button refreshes the page and the user has to scroll all the way back down just to pick up where they left off. This can be quite frustrating for users when I want to incorporate this on something more extensive

I quickly began the like button tutorial but again the refresh issue.

code

<h3><table width="800" border="0"> </h3>

<form name="form2" method="post" action="" >
<?php echo $likerror; ?>
<?php if($profileOwner):?><div style="text-align:left;"><input type="submit"  name="remove" id="remove" value="Delete Posts" /></div><?php endif;?>
<tr style="text-decoration:underline; font-weight:500; font-size:x-large;" >
    <td width="50" height="50" align="center"></td>
</tr>
  <?php
   while($rows = mysql_fetch_array($result9)){

?>
 
<tr>
    <td width="41" align="center"><?php if($profileOwner):?><input type="checkbox" name="checkbox[]" id="checkbox[]" value="<?php echo $rows['id']; ?>" /> <?php endif;?></td>
    <td width="750">

</form>
</table>

note that the like button is within a form where the action is "post". Is this the problem and if so how do I get around it?

You could give each post an ID and then redirect to that.

header("Location: http://www.yourtechview.com/source/prof ... t{$theirid}");

when you do this the browser will scroll down to the element with the id post$theirid whcih would be something like

<h3 id="post<?php echo $theirid; ?>">My post title</h3>

The id has to start with a letter which is why I added the "post"

Also I have to mention, you should really put those queries into functions.

hmm it seems to work somewhat.
It redirects it to the general area of where the post should be on the page but if I'm
looking at a long list of items, it will still require me to scroll up to see the post I left off on.

Also this does not work with firefox and internet explorer.

It will put the element with that ID just visible at the top of the screen, this is done on the HTML as it loads so if you add things with JavaScript or have images that make the page expand that can break it.

It does, fix your HTML
