[SOLVED] why isset doesnt seem to be working?

[marksie1988]

why does this script show information that isnt set in mysql the script with the isset function is still displaying the image when the field has no information in it. why? is it to do with my code below?

 

	<?php
		$req_user = trim($_GET['user']);
		if(!$req_user || strlen($req_user) == 0 ||
		   !eregi("^([0-9a-z])+$", $req_user) ||
		   !$database->usernameTaken($req_user)){
		   die("Username not registered");
		}
		/* Display requested user information */
		$req_user_info = $database->getUserInfo($req_user);

		/* Username */
		echo "<strong>Username:</strong> <br>".$req_user_info['username']."<br><br>";

		/* real name */
		echo "<strong>Real Name:</strong> <br>".$req_user_info['rnme']."<br><br>";

		/* Gender */
		echo "<strong>Gender:</strong> <br>".$req_user_info['Gender']."<br><br>";

		/* Age */
		echo "<strong>D.O.B:</strong> <br>".$req_user_info['dob']."<br><br>";

		/* Location */
		echo "<strong>Location:</strong> <br>".$req_user_info['location']."<br><br>";

		/* Info */
		echo "<strong>Bio/Info:</strong> <br>".$req_user_info['info']."<br><br>";

		echo "<strong>Other Stuff:</strong><br><br>";

		if(isset($req_user_info['skype'])){
		/* Skype */
		echo "<a href='callto://".$req_user_info['skype'] ."'><img src='../images/icons/skype.gif' border='0'/></a>";}
		else{echo"";}
		if(isset($req_user_info['myspace'])){
		/* myspace */
		echo "<a href='http://".$req_user_info['myspace'] ."'><img src='../images/icons/myspace.gif' border='0'/></a>";}
		else{echo"";}
		if(isset($req_user_info['www'])){
		/* myspace */
		echo "<a href='http://".$req_user_info['www'] ."'><img src='../images/icons/www.gif' border='0'/></a>";}	
		else{echo"";}
	?>

Because they are defined. They are just empty. Try:

 

if(!empty($var)){
//echo the data
}

 

Also, next time, use

 tags(without the spaces) around your php code. Makes it a bit easier to read.
