Usage Example

Connecting

Include WP_Term_Image.php php file:

require_once __DIR__ . '/WP_Term_Image.php';

Or use the Composer:

composer require doiftrue/wp_term_image

Initialization

Basic without parameters passing:

add_action( 'admin_init', [ \Kama\WP_Term_Image::class, 'init' ] );

With parameters passing:

add_action( 'admin_init', 'kama_wp_term_image' );

function kama_wp_term_image(){
	
	// Let's specify for which taxonomy it is necessary to set images.
	// It is possible not to specify, then the possibility will be automatically added for all public taxonomies.

	\Kama\WP_Term_Image::init( [
		'taxonomies' => [ 'post_tag' ],
	] );
}

Get data in the theme template

An example of getting the ID of an attachment image of a term:

$image_id = \Kama\WP_Term_Image::get_image_id( $term_id );

// OR
$image_id = get_term_meta( $term_id, '_thumbnail_id', 1 );

Now we can use the ID to get the URL of the attachment:

$image_url = wp_get_attachment_image_url( $image_id, 'thumbnail' );
