Dear Steve

Nope, it isn’t working.
Below is the comment block for the metabox and the codes to be placed under functions.php

/*
Title: Right Bar Section
Description: Customized right bar section
Post Type: page
Hide for Template: page-full-width
Order: 3
*/

add_filter(‘piklist_part_data’, ‘my_custom_comment_block’, 10, 2);
function my_custom_comment_block($data, $type)
{
// If not a Meta-box section than bail
if($type != ‘meta-boxes’)
{
return $data;
}

// Allow Piklist to read our custom comment block attribute: “Hide for Template”, and set it to hide_for_template
$data[‘hide_for_template’] = ‘Hide for Template’;

return $data;
}

add_filter(‘piklist_part_add’, ‘my_hide_for_template’, 10, 2);
function my_hide_for_template($data, $type)
{
global $post;

// If not a meta box than bail
if($type != ‘meta-boxes’)
{
return $data;
}

// Check if any page template is set in the comment block
if (!empty($data[‘hide_for_template’]))
{
// Get the active page template
$active_template = pathinfo(get_page_template_slug($post->ID), PATHINFO_FILENAME);

// Is there a page template set for this page?
if(!empty($active_template))
{
// Does the active page template match what we want to hide?
if (strpos($data[‘hide_for_template’], $active_template) !== false)
{
// Change meta-box access to user role: no-role
$data[‘role’] = ‘no-role’;
}
}
}
return $data;
}

Dear Steve

Thanks. It is resolved.
Due to a custom field name “image” which was registered earlier, it caused the issue when I try to do the above.
