Page options, dropdowns and settings

Simple post for today. I have a optional plugin for a googlemap wich uses other custom post types wich supports the dimme_googlemaps in the post. You can read it all in the post type supports section. But what you need is a page wich to post the information, and the googlemap wich it supports.

Building it i have a simple settings form including a form on a settings page posting to options.php. You have to save the items through a hidden field. So in example:

<form method="post" action="options.php">
  <?php wp_nonce_field('update-options'); ?>
  <select name="dimme_option">etc</select>
  <input type="text" name="dimme_option_info">
  <input type="hidden" name="action" value="update" />
  <input type="hidden" name="page_options" value="dimme_option,dimme_option_info" /> 

Simple enough. Create a form with two fields, save it using the page_options hidden field. Comma seperated couse it has to be. But, i need a select getting the pages of my site so i can add a page option for the page i want my post type to get on. I can`t realy understand my last sentence.

So for an example. I want pages in a select:


Select created. Add a name and a “none” option and my page is.

$args = array(
  'selected' => get_option('dimme_page_id'),
  'name' => 'dimme_page_id',
  'show_option_none' => '- choose -'

Added my page, saves it to the options dimme_page_id, selected it default when selected. Add the args to the dropdown pages and done with the settings page. Now we can easily use the option in a template_include filter wich is not found in the wordpress codex, so an example:

function dimme_template_loader( $template ) {
  $page_id = get_option('dimme_page_id');
  if ( is_page( $page_id )) {
    $template = plugin_dir_path(__FILE__) . 'mypage.php';
  return $template;
add_filter( 'template_include', 'dimme_template_loader' );
