All About is_tag WordPress function

The is_tag() function is responsible for determining whether the query is a tag archive page that already exists. Here is the syntax of the is_tag function:

is_tag( int|string|int[]|string[] $tag = '' )

According to our Support Techs, specifying the $tag in the function pushed it to check if the query is for any of the tags specified. The parameter $tag can be Tag ID, slug, array, or name to check against.

$bool = is_tag( $tag );

Here is a quick look at the code of the is_tag function:

function is_tag( $tag = '' ) {
	global $wp_query;

	if ( ! isset( $wp_query ) ) {
		_doing_it_wrong( __FUNCTION__, __( 'Conditional query tags do not work before the query is run. Before then, they always return false.' ), '3.1.0' );
		return false;
	}

	return $wp_query->is_tag( $tag );
}

Here are a few examples of how to use the is_tag function:
