Ifstatement used to make a functionality button appear?

I am on my 2nd day(16th hour) of trying to get my delete button to do what I want with PHP. I have a site that is a social network that has user profiles. Users can leave comments on another users profile. I am trying to put a delete link in a designated area that only shows up if you are viewing your own profile and goes away when you are viewing someone elses profile. I am also not wanting to make a delete confirm page. I want the page to reload w开发者_StackOverflow社区ith the comment selected to delete gone, and be sent to my db marked as dead. This is what I have so far:

           <?php

           $query = "SELECT * FROM `ProfileComments` WHERE `ToUserID` = '".$prof->id."' ORDER BY `date` DESC, `time` DESC LIMIT 10";


           $request = mysql_query($query,$connection);


           while($result = mysql_fetch_array($request)) {





           $poster = new User($result['FromUserID']);

           echo "<div id='CommentProfile'>";
           echo "<div id='CommentPhotoProfile'>";
           echo "<a href='http://www.blah.org/Profile.php?id=".$poster->id."'>";
           echo "<img src='" . $poster->img('mini') . "' border='0'/>";
           echo "</a>";
           echo "</div>";
           echo "<div id='ProfileCommentBody' class= 'round_10px'>";
           echo "<div id='CommentNameProfile'>";
           echo "<div class='ProfileCommentTail'>&nbsp;</div>";
           echo "<a href='http://www.blah.org/Profile.php?id=".$poster->id."'>";
           echo $poster->first_name. " ". $poster->last_name. " <span style='font-weight:normal'>says...</span>";
           echo "</a>";
           echo "</div>";
           echo stripslashes(nl2br($result['commentProfileBody']));
           echo "<div id='CommentInfoProfile'>";
           echo date('M d, Y',strtotime($result['date']));
           echo " at " . date('g:i A',strtotime($result['time']));
           if ($poster->id == $prof->id)
           echo "<a href='http://www.blah.org/DeleteComment.php?id=".$prof->id."'>";
           echo " delete";
           echo "</a>";
           echo "</div>";
           echo "</div>";
           echo "</div>";
           }

           ?>

do I need to make a seperate query underneath the one I already have that is for the composition of the comments? do I need to add on to that query? how do I make the delete button only appear when the user is looking at their own page? how do I make the page reload with the comment gone after I selected it deleted and mark it dead in the db?

thank you in advance

Be careful if all you do after authorization of the delete privilege is then hide or not hide a button.

If users figure out another way to invoke the delete action, that kind of authorization checking won't work. For example, if your implementation uses a "delete URL" that encodes the delete command, and your button merely POSTs to that URL, then when the button is hidden, a user could manually post the delete command.

Fill in your variables:

if ($current_user_id == $profile_user_id)
    echo '<a href="deletelink">delete</a>';

This is toatlly lame, code, but just a random thought since you are really giving us nothing to work with. Take it for what it is:

function getPageUserID()
{
    return $_GET['userID'];
}
if ($user->userID == getPageUserID())
{
 //show delete button
    echo '<button value="Delete">Delete</button>';
}
