Having Trouble with Cases in a Switch

[eoghan]

Hi, I've been having a bit of a headache with a troublesome switch statement. The problem is that when I try to call one case (eg. search) the first case shows instead (eg. list). I dont see a syntax error or sematic error, maybe one of you can. Any help is appreciated.

<a href="mypage.php">Add</a> | 
<a href="mypage.php?page=list">Edit/Delete</a> | 
<a href="mypage.php?page=search">Search</a>

<?php
// using isset() to stop 'Undefined Index' error
$page = isset($_GET['page']);

switch ($page) {
    case 'list':
?>
// prints a html table with a list of users from DB
<?php
    break;
    case 'search':
?>
// prints another html table with search options
<?php
    break;
    default:
?>
// prints another html table for adding users to the DB
<?php
} // End Switch
?>

Read the PHP Manual on [man]isset/man to understand why your use of isset() is not correct.

hey, i figured that a while ago, isset() returns a value of 1, I was concentrating on not getting that damned undefined index error and didnt think of the consequences of using isset().

For anyone that wants to know the way i got around the Undefined Index error was by using

if (array_key_exists('page',$_GET)) {
    // switch bla bla bla
} else {
    // output default html
}

A simple...

if (isset($_GET['page'])) {
  $page = $_GET['page'];
} else {
  $page = '';
}

Would have sufficed.

$page = (isset($GET['page'] ? $GET['page'] : '');

Is also an option (if theres a value for page, use it, otherwise return blank '' or whatever you prefer.
