Hi,

I am trying to complete a button which allows someone to follow somone else. It is designed to be a social networking button. I could get the button to work whever the page is loaded which is highly undersirable but I cant make it work when the button is pressed.

I have really stuck on this, does anyone have any suggestions on what I can try to get it to work.

Code:
<?php
 
	

 $followerid = intval($_SESSION['userID']);
        $profileid  = intval($row['id']);
		

	
if(isset($_POST['followbutton']) && $_POST['followbutton'] == 'true'){


	if($profileid =  $followerid) {
        $errors['profileid'] = "This is a test error.";
    }



if(!$errors){
        //Validation of input vars passed, attempt to run query
        //Force vars to be ints to be safe for query statement

		
		    $followerid = intval($_SESSION['userID']);
        $profileid  = intval($row['id']);

        $query = "INSERT INTO `follow` (`user_id`, `follow_user_id`) VALUES ('{$profileid}', '{$followerid}')";
        $result = mysql_query($query);

		
        if (!$result)
        {
                $errors[] = "Query: {$query}<br>Error: " . mysql_error();

        }
	}	
	}
	
	
?>
