Admin page to manage default templates

The Solution

We will use the following solutions:

• using site option to save the page id for each template.
• create empty pages during activation. using wp_insert_post
• set initial values for each site option after page created.
• page template page on dashboard to allow user to select different pages for each page templage. Using wp_dropdown_pages to list all available pages.
• using WordPress filter template_include to apply the page template.
• using is_main_site to make sure this is a page from main root site.
• using WordPress function is_page to pick the right page.

List of site options to save the page id for each page template:

• wptc_page_trac
• wptc_page_trac_ticket
• wptc_page_trac_mytickets

The default page slugs

• trac
• ticket
• mytickets

post data for pages, place holder pages

$post_data = array(
    'post_status' => 'publish',
    'post_parent' => '',
    'post_type' => 'page',
    'ping_status' => get_option('default_ping_status'),
    'post_content' => ' ',
    'post_excerpt' => '',
    'post_title' => __('trac', 'wptc')
);
$id = wp_insert_post($post_data, false);

if you call the function wp_insert_post from network dashboard, the page will be created under root blog.
