Let’s say you want to be sure every single post, in ever single post type, has a featured image. And you know someone might forget but you don’t want to have to open up every damn post to see.
There are a lot of answers to this problem, and I love that there’s a plugin that will add in a Featured Image Column that shows a teeny featured image. But it wasn’t what I wanted. It was over kill.
All I needed was a simple check mark for if there was an image and an X if there wasn’t, and that would suit me fine. And I wanted the column to be small, without a lot of fuss or folderol. I wanted something simple:
That gives me a fast overview of if everything is what I wanted and where I wanted.
The Code
The code itself is the most basic column code, with a little bit of magic to put it as the first column on the list. Since I want to show this on all post types, I used the generic functions.
/*
* Show mark if featured image is set
*
* @since 1.1
*/
add_filter('manage_posts_columns', 'helf_fi_manage_posts_columns');
function helf_fi_manage_posts_columns( $columns ) {
if ( !is_array( $columns ) ) $columns = array();
$new_columns = array();
foreach( $columns as $key => $title ) {
if ( $key == 'title' ) $new_columns['featured_image'] = '<span class="dashicons dashicons-camera"></span>';
$new_columns[$key] = $title;
}
return $new_columns;
}
add_action('manage_posts_custom_column', 'helf_fi_manage_posts_custom_column', 10, 2);
function helf_fi_manage_posts_custom_column( $column_name, $post_ID ) {
if ($column_name == 'featured_image') {
$post_featured_image = helf_fi_manage_column_check( $post_ID );
$output = '<span class="dashicons dashicons-no"></span>';
if ( $post_featured_image && $post_featured_image == true ) $output = '<span class="dashicons dashicons-yes"></span>';
echo $output;
}
}
function helf_fi_manage_column_check( $post_ID ) {
$post_thumbnail_id = get_post_thumbnail_id( $post_ID );
$post_thumbnail_img = false;
if ( $post_thumbnail_id ) $post_thumbnail_img = true;
return $post_thumbnail_img;
}
add_action( 'admin_print_scripts', 'helf_fi_admin_print_styles' );
function helf_fi_admin_print_styles(){
echo '
<style>
th#featured_image,
td.featured_image.column-featured_image {
max-height: 25px;
max-width: 25px;
width: 25px;
color: #444;
}
td.featured_image span.dashicons-no {
color: #dc3232;
}
td.featured_image span.dashicons-yes {
color: #46b450;
}
div#screen-options-wrap.hidden span.dashicons-camera {
padding-top: 5px;
}
</style>';
}
Fork and enjoy!
