Bundle a page with custom url and a function

Make a new file and include a page template to structure the loop and display your bookmarks.

<?php
/**
 * Template Name: Bookmarked Page
 *
 * @package WordPress
 * @subpackage Twenty_Fourteen
 * @since Twenty Fourteen 1.0
 */

Then just make sure a page exists called bookmarked (so the url is in place) and set it’s template to the custom page template you created.

You can also write a template to target a specific page.

1. page-{slug}.php
2. page-{ID}.php

is_bookmarked_page() isn’t really required because you will already know your template is being used. There are however page template functions that could help.

• get_page_template ()
• wp_get_theme()->get_page_templates()
• is_page_template()
• get_page_template_slug()

It’s also possible to construct this page automatically after_switch_theme by creating the page using wp_insert_post and setting the template with update_post_meta.

Create the page if it doesn’t already exist:

$title = __( 'Bookmarks' );
if ( NULL == get_page_by_title( $title ) ) {
    $post_id = wp_insert_post(
        array(
            'post_name'      => 'bookmarked',
            'post_title'     => $title,
            'post_content'   => '',
            'post_type'      => 'page',
            'comment_status' => 'closed',
            'ping_status'    => 'closed',
            'post_status'    => 'publish',
        )
    );
}

Set the page template:

$template_full_path = trailingslashit( get_stylesheet_directory() ) . $template_rel_path;

if ( file_exists( $template_full_path ) ) {

    // set the post meta data -- use relative path
    update_post_meta( $post_id, '_wp_page_template', $template_rel_path );
}
