Wordpress - How to add add_meta_box to specific Page Template?
If your custom page template filename is foobar.php
, you can use get_post_meta()
:
global $post;
if ( 'foobar.php' == get_post_meta( $post->ID, '_wp_page_template', true ) ) {
// The current page has the foobar template assigned
// do something
}
Personally, I like calling this inside my add_meta_boxes_page
callback, and wrapping it around the add_meta_box()
call itself.
function wpse82477_add_meta_boxes_page() {
global $post;
if ( 'foobar.php' == get_post_meta( $post->ID, '_wp_page_template', true ) ) {
add_meta_box( $args );
}
}
add_action( 'add_meta_boxes_page', 'wpse82477_add_meta_boxes_page' );
You'll just need to instruct users to save the page after assigning the template, so that the meta box appears.
I found a few bugs with the answer above option above but I customized this option below and it helped - no bugs at all.
add_action('add_meta_boxes', 'add_product_meta');
function add_product_meta()
{
global $post;
if(!empty($post))
{
$pageTemplate = get_post_meta($post->ID, '_wp_page_template', true);
if($pageTemplate == 'page-templates/product-page.php' )
{
add_meta_box(
'product_meta', // $id
'Product Information', // $title
'display_product_information', // $callback
'page', // $page
'normal', // $context
'high'); // $priority
}
}
}
function display_product_information()
{
// Add the HTML for the post meta
}
