[RESOLVED] Changing variable with IF statement

[angershallreign]

Hello guys. I am working on a PHP page, where the content of the page changes depending on the option clicked in the navigation bar. I was following a tutorial on how to do this, but the tutorial didn't work to the effect I wanted.

Is it possible that someone here, who is more experienced at PHP than myself, could help me out? This is the code I have so far, but it doesn't seem to work. I would post the error message I get, but everytime I find where I've gone wrong and fix it, another (different) error message comes up.

<?php
$navbar = "| <a href=\"games.php?id=intro\" title=\"Page intro\">Intro</a> | <a href=\"games.php?id=bluetruck\" title=\"Blue Truck\">Blue Truck</a> | <a href=\"games.php?id=redhouse\" title=\"Red House\">Red House</a> | <a href=\"games.php?id=brownbear\" title=\"Brown Bear\">Brown Bear</a> |";


if ($_GET['id'], bluetruck) { 
 $content = "Blue Truck"; 
} 

if ($_GET['id'], redhouse) { 
 $content = "Red House"; 
} 

if ($_GET['id'], brownbear) { 
 $content = "Brown Bear"; 
} 

elseif (!isset($_GET['id'])) { 
 $content = "Intro"; 
} 


include "template.php";
?>

Any help would be much appreciated 😃

Hmmmm...

if(!isset($_GET['id'])) {
    $content= 'Intro';
} elseif ($_GET['id'] == 'bluetruck') {
     $content = 'Blue Truck';
} elseif ($_GET['id'] == 'redhouse') {
     $content = 'Red House';
} elseif ($_GET['id'] == 'brownbear') {
     $content = 'Brown Bear';
}

Or...

$array_content = array(
    'bluetruck'    => 'Blue Truck',
    'redhouse'    => 'Red House',
    'brownbear'    => 'Brown Bear'
);
$content = ((isset($_GET['id']) && isset($array_content[$_GET['id']])) ? $array_content[$_GET['id']] : 'Intro');

Thank you for taking the effort to correct my code, suntra 😃

I just tried both codes and, whilst the first one doesn't seem to work properly, the second one is perfect.

If you are wondering what I mean by it "doesn't seem to work properly", it shows the "Intro" page initially but when it is clicked again the content goes blank.

Anyway, thanks once again. I really appreciate it 🙂

I'll definately be sticking around this site. It's great how fast I recieved help.
