Images not displaying

[fiona@vas]

I'm very new to php and am trying to fix code that was previously working.

Initially, i was getting an undefined error and changed code from:

function printChapter($committee){

	echo "<table width=\"99%\" border=\"0\" cellspacing=\"10\">\n";

	foreach($committee as $name => $c){
		
		$alt = $name;
		$names = explode(" ", $name);
		$fname = $names[0];
		
		$lname = "";
		for($i = 1; $i <= 3; $i++){
			$lname .= $names[$i];
		}

to:

function printChapter($committee){

	echo "<table width=\"99%\" border=\"0\" cellspacing=\"10\">\n";

	foreach($committee as $name => $c){
		
		$alt = $name;
		$names = explode(" ", $name);
		$fname = $names[0];
		
		$lname = "";
		for($i = 1; $i <= 3; $i++){
			$lname .= isset($names[$i]);
		}

Which stopped the undefined error....but now the images are not displaying at all...

<?php
function get($value)
{
	return isset($_GET[$value]) ? $_GET[$value] : null;
}

function post($value)
{
	return isset($_POST[$value]) ? $_POST[$value] : null;
}

function error($error)
{
	echo "<div id=\"error\">{$error}</div>\n";
}

function success($message)
{
	echo "<div id=\"success\">{$message}</div>\n";
}

function session($var)
{
	return $_SESSION[$var];
}

function allgroups()
{
	$link = connect();
	$query = "SELECT * FROM `groups`";
	select($query, $result_set, $link);
	$groups = array();
	$count = 0;
	while (($row = next_result($result_set)) != null) {
		$groups[$count]["id"] = $row["id"];
		$groups[$count]["name"] = $row["name"];
		$groups[$count]["mask"] = $row["mask"];
		$count++;
	}
	return $groups;
}

function printChapter($committee){

	echo "<table width=\"99%\" border=\"0\" cellspacing=\"10\">\n";

This piece is wrong:

for($i = 1; $i <= 3; $i++){
			$lname .= isset($names[$i]);
		}

What you're actually saying is: Add the return-value of the function "isset" to the string "$lname". So it's trying to add true or false to your string. What you probably meant was:

for($i = 1; $i <= 3; $i++){
     if (isset($names[$i])) {
         $lname .= isset($names[$i]);
     }
}

Which means: If names has a value, add it to $lname.
