Snippets by IsItWP

Are you looking for a way to add a new tab to the featured image popup? While there’s probably a plugin for this, we have created a quick code snippet that you can use to add custom tab to featured image media library popup in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

function mime_type_tab($tabs) {
        /* name of custom tab */
	$new_tab = array('mimeframe' => __('Mime Types', 'mimetype'));
	return array_merge($tabs, $new_tab);
}
add_filter('media_upload_tabs', 'mime_type_tab');


function create_mime_type_page() {
	media_upload_header();
        wp_enqueue_style( 'media' );

        /* add custom code to display bellow this line */
	/* display mime types */
	$mimes = get_allowed_mime_types();
	$types = array();

	echo '<div class="type-outer">';
	echo '<h3 class="media-title">Supported file types</h3>';
	echo '<hr />';

	foreach ($mimes as $ext => $mime) {
		 $types[] = '<li>' . str_replace('|', ', ', $ext) . '</li>';
	}
	echo '<ul class="mime-types">' . implode('', $types) . '</ul>';
	echo '</div>';
       /* end custom code */
 
}

function insert_mime_type_iframe() {
    return wp_iframe( 'create_mime_type_page');
}
add_action('media_upload_mimeframe', 'insert_mime_type_iframe');

	add_action( 'admin_head', 'mime_frame_css' );
	function mime_frame_css() {
		echo '<style type="text/css">
		.type-outer{margin:20px;}
		.type-outer hr{
			border:solid #ccc;
			border-width:0px 0px 1px 0px;
			margin:0px 0px 20px 0px;
			}
		.mime-types li{
			font-size:10px;
			float:left;
			width:24%;
			padding:1px;
			}
			</style>';
	}
