Php Switch Case
jfcby
redirect to another webpage, or echo text. I have this page in the
main www folder on the server.
My problem is if I type the webpage address like so www.ebooktaught.com/prodtest.php
then it displays the first switch case instead of the default.
How can I get the following script to:
1. After I type in www.ebooktaught.com/prodtest.php it will display
the default echo?
2. How can I get the script to work if I type in
www.ebooktaught.com/prodtest.php?pg=pd&nb=2 for it to display the
second switch case?
[code]
<?php
$gpg = $_GET["pg"];
$gnb = $_GET["nb"];
Switch ($gpg){
Case $gpg == 'pd' && $gnb == 1:
echo "Product Page = " . $_GET['pg'] . " & Product Page # = " .
$_GET['nb'];
break;
Case $gpg == 'pd' && $gnb == 2:
echo "Product Page = " . $_GET['pg'] . " & Product Page # = " .
$_GET['nb'];
break;
Case $gpg == 'sp' && $gnb == 1:
echo "Product Page = " . $_GET['pg'] . " & Product Page # = " .
$_GET['nb'];
break;
Case $gpg == 'sp' && $gnb == 2:
echo "Product Page = " . $_GET['pg'] . " & Product Page # = " .
$_GET['nb'];
break;
default:
echo "Default";
}
?>
[/code]
Thank you for your help,

You don't understand the switch/case syntax:

matt,
I've read through that website and there are no examples of what I'm
trying to do.
This is what I'm trying to do. I want to be able to type in a web
address like so www.ebooktaught.com/prodtest.php?pg=pd&nb=2 and have
my php switch case statement display the correct information. Is this
possible with a switch case statement and where can I find some
examples of the correct way to do it because the link you provided
does not show how to do that?

No, it's not. You will need to use a series of if/else if statements.

These values may not exist. Try this instead:
<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
$gpg = isset($_GET['pg']) ? $_GET['pg'] : NULL;
$gnb = isset($_GET['nb']) ? $_GET['nb'] : NULL;

Perhaps it's a pet peeve of mine but my eyes bleed when I see PHP
control structures in sentence case... :)

Right, this is a boolean expression so it will return either TRUE or
FALSE. You can *never* get a match: even if $gpg equals 'pd' and $gnb
equals '1', the expression is TRUE, which is different from 'pd'. I
presume you want this:
