I made a plugin with a custom post type postcard. Most of postcards are private.

I would like to redirect the logged out user in a specific php file inside my plugin instead of the 404.php or achive.php.

I tried with template_redirect action like this :

add_action( "template_redirect", array( "MyClass", "is_redirection" ) );

Class MyClass{

    public static function is_redirection(){
        if( is_404() ) {
            global $post_type;
            if( $post_type === "postcard" ){
                $templates_dir = get_current_plugin_templates_dir_path();
                $page404 = $templates_dir . "/404-" . $post_type . ".php";
                if ( file_exists( $page404 ) ) {
                   wp_redirect( $page404 );
                   exit;
                }
            }
        }
    }  
}

My probleme here is $page404 is a file path, not an url so... How can I do this wihtout using .htaccess?

• 404-error
• wp-redirect
• template-redirect

• I'm not sure what get_current_plugin_templates_dir_path() is -- I don't think it's a WordPress function. – Pat J Commented Aug 23, 2019 at 20:45
• get_current_plugin_templates_dir_path() is just a function I did to get a path like file-path-to-my-plugin-dir/front-end/templates/ – J.BizMai Commented Aug 23, 2019 at 20:51

This should work for you, using plugins_url():

...
// Assumes that your templates are in a subdirectory called 'templates' in your plugin. 
// Adjust accordingly.
$templates_dir = plugins_url( 'templates', __FILE__ );
$page_404      = $templates_dir . '/404-' . $post_type . '.php' );
...

Update: template_include

If you want to have WordPress loaded up, you might be better off to use the template_include filter.

add_filter( 'template_include', array( 'MyClass', '404_template' );
class MyClass {
    function 404_template( $template ) {
        if ( is_404() ) {
            global $post_type;
            $my_template = plugins_url( 'templates/404-' . $post_type . '.php' , __FILE__ );
            if ( file_exists( $my_template ) ) {
                $template = $my_template;
            }
        }
        return $template;
    }
}
