Hide Sidebar From A Custom Post Type (CPT) In WordPress

If you’re looking to hide a sidebar from a custom-post-type (CPT) in WordPress, you can make use of the following code:

function ob_no_sidebar( $class ) {

	// Alter your layout
	if ( is_singular( 'job_listing' ) ) {
		$class = str_replace("has-sidebar","",$class);

	// Return correct class
	return $class;

add_filter( 'body_class', 'ob_no_sidebar', 20 );

This is something I created for the custom-post-type job_listing in WP Job Manager plugin. This code basically adds a body_class filter and the runs my function ob_no_sidebar.

My function will check if the current post type matches XYZ then it’ll replace the has-sidebar class with an empty string and that does the job.
