Introduction

This developer’s tutorial will go through the ways for obtaining and displaying a featured picture in WordPress. We will provide some PHP code snippets that you may use in your custom plugins, teams, or page builders that support PHP.

Featured photos are the first impression that visitors get when they visit a WordPress page or post. They’ve been a cornerstone of WordPress since its inception, and are commonly used at the top of blog articles. Featured image not showing in the custom post type? here is a solution.

WordPress featured image meta box is a fantastic feature. It allows you to select the featured image for a post or page quickly. What about custom post types, though? Yes, you can use the supports parameter to enable the featured image meta box for your custom post types.

“The code is here! just Copy and Paste in the theme main functions.php file”

add_action( 'after_setup_theme', 'cxc_add_post_thumbnail_supports', 99 );
function cxc_add_post_thumbnail_supports() {
	add_theme_support( 'post-thumbnails' );
}

We can show feature images for the specific custom post types.

“Here we can create custom post type for movie and show post thumbnails for there.“

add_action( 'init', 'cxc_custom_init' );
// 'movie' is my post type, you replace it with yours
function cxc_custom_init() {
	add_post_type_support( 'movie', 'thumbnail' );
}

Alternative solutions

<?php 
add_filter( 'register_post_type_args', 'cxc_add_post_theme_support_args', 10, 2 );
function cxc_add_post_theme_support_args( $args, $post_type ){
	//You need to add the name of your new custom post type at the current theme.
	if ( $post_type == 'news' ) {
		$args['support'] = 'thumbnail';
	}
	return $args;
}
?>

Alternative solutions

add_action( 'init', 'cxc_theme_register_custom_post_type' );
