Set another page.tpl.php if a parameter is set

Question

i want to use another page.tpl.php file, if die fb parameter is set. The File is located in my theme folder and has the name "page-fb.tpl.php"

My Function in template.php

function THEMENAME_preprocess_page(&$vars) {
/** Facebook Output */
    if ( isset($_GET['fb']) && $_GET['fb'] == 1 ) {
        $vars['template_file'][] = 'page-fb';
    }
}

The function is called, but the new page-fb.tpl.php is not loaded. I'm doing all of this on Drupal 7.

Any advices?

Answer 1

Rename page-fb.tpl.php to page--fb.tpl.php and then modify your code to use $vars['theme_hook_suggestions'][] = 'page__fb'; instead of what you got currently. For further information you can check out the Drupal 7 Template Suggestions page.

Answer 2

Here you made a mistake!

$vars['template_file'][] = 'page-fb';

The above line should be like below.

$vars['template_files'][] = 'page-fb';
