WordPress: Remove Featured Image From Specific Page - wordpress

Question

I was able to remove the featured image metabox from custom post types of pages. Below is what I used:
add_action('do_meta_boxes', 'remove_thumbnail_box');
function remove_thumbnail_box() {
remove_meta_box( 'postimagediv','page','side' );
}
However, what I really want to do is to only apply this to a specific page template. Is this possible?
Thanks!

Answer 1

Ah, I found a solution.
$post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'] ;
$template_file = get_post_meta($post_id,'_wp_page_template',TRUE);
if ($template_file === 'page-template-name.php') {
add_action('do_meta_boxes', 'remove_thumbnail_box');
function remove_thumbnail_box() {
remove_meta_box( 'postimagediv','page','side' );
}
}
If there's a better solution... please don't hesitate to post.
Thanks!

For anyone else looking to remove featured image support programatically (the comments should be self explanatory):
/**
* Removes the featured image metabox from specific pages (by ID)
* #note: populate the $excluded_page_ids_array array with page IDs
*/
function eh_remove_featured_image_metabox_from_specific_pages() {
// populate with page IDs to exclude featured image metabox from
$excluded_page_ids_array = array( 38, 29 );
// store the current post ID
$post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'];
// check if the current page is in our excluded array
if( in_array( $post_id, $excluded_page_ids_array ) ) {
// remove featured image metabox
remove_meta_box( 'postimagediv','page','side' );
}
}
add_action( 'do_meta_boxes', 'remove_featured_image_metabox_from_specific_pages' );
After adjusting the array of pages to exclude, you'll want to add this snippet to your themes functions.php file.
Alternatively, you can remove the featured image from all pages, except specified ones - where the featured image metabox will remain.
/**
* Removes the featured image metabox from all pages except specified ones
* #note: populate the $page_ids array with page IDs
*/
function eh_remove_featured_images_metabox_from_all_pages_except_specified() {
// populate with page IDs to keep the featured image metabox on
$page_ids = array( 25, 31 );
$post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'];
if( ! in_array( $post_id, $page_ids ) ) {
// remove featured image metabox
remove_meta_box( 'postimagediv','page','side' );
}
}
add_action( 'do_meta_boxes', 'eh_remove_featured_images_metabox_from_all_pages_except_specified' );

There is another solution. By editing the page.php
If your feature Image div Looks like below for example
<div class="thumbnail">
<?php echo get_the_post_thumbnail( $post_id, $size, $attr ); ?>
</div>
you can use
if (is_page( array( 42, 'about-me', 'Contact' ) );
// Returns true when the Pages displayed is either post ID :42, or post_name_slug "about-me", or post_title "Contact".
<?php
if (is_page( array( 42, 'about-me', 'Contact' ) ) ) {
?>
<div class="thumbnail" style="display:none;">
<?php echo get_the_post_thumbnail( $post_id, $size, $attr ); ?>
</div>
<?php
}else{
?>
<div class="thumbnail">
<?php echo get_the_post_thumbnail( $post_id, $size, $attr ); ?>
</div>
<?php}?>
