if($_GET['page']) Error

Question

Hello i have this script.

if($_GET['page']) {
        if (isset($_GET['page']))
        $id = $db->escape_string($_GET['page']);
        if ($usersquery = $db->query("SELECT * FROM padges WHERE id ='$id' LIMIT 1"))
        $content = $usersquery->fetch_assoc();
    }
    if(!$_GET['page']) {
        if (isset($_GET['page']))
        $id = $db->escape_string($_GET['page']);
        if ($usersquery = $db->query("SELECT * FROM padges WHERE ID ='10' LIMIT 1"))
        $content = $usersquery->fetch_assoc();
    }

If i go to http://127.0.0.1/?page=10 i have no error. But if i go to http://127.0.0.1 i get this error.

Notice: Undefined index: page in /sites/ergotherapiewalcheren.nl/www/index.php on line 6 Notice: Undefined index: page in /sites/ergotherapiewalcheren.nl/www/index.php on line 12

How can i fix this error?

`if (isset($_GET['page']))` should check to see if `page` has been passed in. — andrewsi, Oct 29 '15 at 22:40
Read about [$_GET](http://php.net/manual/en/reserved.variables.get.php) and [isset()](http://php.net/manual/en/function.isset.php) — Dan, Oct 29 '15 at 22:40

The first check should not be needed, remove:

if($_GET['page']) {

As you are already checking if it's set:

if (isset($_GET['page']))

Tnx I have if (! $ _ GET ['page']) {delete, only now I get this error Notice: Undefined variable: id in /sites/ergotherapiewalcheren.nl/www/index.php on line 9 – Tom Lammers Oct 29 '15 at 22:44
instead of using an if to check if it's set and another if to check if it's not set, use if/else. – taxicala Oct 29 '15 at 22:46
