Usage

Examples

#1 Demo - check format

Suppose we need to check the format of the post (inside the loop) and display an icon if it is, say, video format:

// inside the loop

if( has_post_format( 'video' ) ){ 

	echo "<img src="icon link" alt=""/>";
 }

#2 Example of specifying multiple formats to check

Suppose our posts are conventionally divided into news (regular posts) and media (posts with galleries and videos). When outputting in the loop, we need to mark the posts as "media". To do this, we will specify the formats as an array:

if( has_post_format( array('video', 'gallery') ) ){
	// this is a media post
}

#3 Checking the format of a specific post

This example shows how to check the format of a post with ID = 23:

if( has_post_format( 'status', 23 ) ){
	// it's status
}
