php if isset _GET chapter or marker

Question

I have an index.php and in it I want to generate the page template it should show. So when you're on index.php you see the home.php template.

If you're on the index.php?chapter=chapter-name you see the chapter.php template. And if you're on the index.php?marker=marker-name you see the marker.php template.

I now have the following:

<?php
    if(!isset($_GET["chapter"])){
        $page = "root";
        include_once('view/home.php');
    } else {
        $page = $_GET["chapter"];
        switch($page){
            case "chapter-name":
            include_once('view/chapter.php');
            break;

            case "marker-name":
            include_once('view/marker.php');
            break;
        }
    }
?>

Thanks!

//Array of configuration views
$config_template = array(
    'default' => 'view/home.php' ,
    'chapter-name' => 'view/chapter.php' ,
    'marker-name' => 'view/marker.php' ,
) ;
//Logic to call template
$include = $config_template['default'] ;
if ( isset( $_GET['chapter'] ) && array_key_exists( strtolower( $_GET['chapter'] ) , $config_template ) ) {
    $include = $config_template[$_GET['chapter']] ;
}
else if ( isset( $_GET['marker'] ) && array_key_exists( strtolower( $_GET['marker'] ) , $config_template ) ) {
    $include = $config_template[$_GET['marker']] ;
}
//include template
include_once($include) ;

This way the code is ready to grow up...

i think you want something like this

<?php
    if(isset($_GET["chapter"]) && $_GET["chapter"]=='chapter-name')
    {
        $page = $_GET["chapter"];
        include_once('view/chapter.php');
    }
    else if(isset($_GET["marker"]) && $_GET["marker"]=='marker-name')
    {
        $page = $_GET["marker"];
        include_once('view/marker.php');
    }
    else
    {
        $page = "root";
        include_once('view/home.php');
    }
?>

Maybe you want something like this ?

<?php
if(isset($_GET["chapter"])) {
    $page = $_GET["chapter"];
    include_once('view/chapter.php');
} else if(isset($_GET["marker"])) {
    $page = $_GET["marker"];
    include_once('view/marker.php');
} else {
    $page = "root";
    include_once('view/home.php');
}
?>

With $_GET["chapter"] you will never get 'marker-name' because it is in $_GET["marker"]
