Filter [post_categories] / [post_terms] shortcodes to exclude categories

[AJD]

Hi,

I'm stuck trying to filter the [post_categories] shortcode to exclude some specific categories from display. I'd like to use the ID to do this.

Is there a filter for this?

EDIT: I realize I also need to filter [post_terms], because I need to do the same thing for a custom post type/taxonomy.

Thanks
AJ

You can create a custom version of the post categories shortcode and then filter the post meta in the entry footer

Use the original function as a guide.

add_shortcode( 'post_categories', 'genesis_post_categories_shortcode' );
/**
 * Produces the category links list.
 *
 * Supported shortcode attributes are:
 *   after (output after link, default is empty string),
 *   before (output before link, default is 'Tagged With: '),
 *   sep (separator string between tags, default is ', ').
 *
 * Output passes through 'genesis_post_categories_shortcode' filter before returning.
 *
 * @since 1.1.0
 *
 * @param array|string $atts Shortcode attributes. Empty string if no attributes.
 * @return string Shortcode output
 */
function genesis_post_categories_shortcode( $atts ) {

	$defaults = array(
		'sep'    => ', ',
		'before' => __( 'Filed Under: ', 'genesis' ),
		'after'  => '',
	);

	$atts = shortcode_atts( $defaults, $atts, 'post_categories' );

	$cats = get_the_category_list( trim( $atts['sep'] ) . ' ' );

	//* Do nothing if no cats
	if ( ! $cats ) {
		return '';
	}

	if ( genesis_html5() )
		$output = sprintf( '<span %s>', genesis_attr( 'entry-categories' ) ) . $atts['before'] . $cats . $atts['after'] . '</span>';
	else
		$output = '<span class="categories">' . $atts['before'] . $cats . $atts['after'] . '</span>';

	return apply_filters( 'genesis_post_categories_shortcode', $output, $atts );

}

Or, use the genesis_post_categories_shortcode filter to modify the default.

Hi, Thanks,
I did find the code and filter, however am at a loss of how to proceed from there.

Understand. You'll need a custom filter function written for what you want unless you can find an existing tutorial already published which includes the code you need.

Hi, I landed up creating a customized get_the_terms_list() function to use in a custom post_info shortcode. (For the custom taxonomy)

Cheers!
