if id is not set how do I say SET ID equal to ...

[futrose]

I'm trying to set up my home page so that when the server loads index.php it that loads home.php but all the information for home.php is stored in the database under ID 13.  So how can I say at the top of my home page that if

if (!isset($_GET['id']))
{
$id == 13;
}

(this doesn't seem to work)

so that all my variables are populated with the information for the home page?

Thanks.

If $_GET['id'] is to be an integer (and 0 isn't a valid value), you can use this

if( intval($_GET['id']) < 1 ) {
     $id = 13;
} else {
     $id = (int) $_GET['id'];
}

I tried that but I get an "undefined index: id in line 2"

$id = 13;

Does the code you gave me work even if the ID is empty or hasn't be set to anything yet?

Make a change to it . . . Sorry, this should take of the undefined index warning.

 

if( empty($_GET['id']) || intval($_GET['id']) < 1 ) {

    $id = 13;

} else {

    $id = (int) $_GET['id'];

}
