Customize infobox content

Replace the default excerpt-based infobox body with custom HTML built from meta fields, taxonomies, or shortcodes.

/**
 * Custom Progress Map infobox description.
 *
 * @param string $default_content Default content.
 * @param int    $post_id         Location post ID.
 */
function my_custom_infobox_description( $default_content, $post_id ) {

	$name    = get_post_meta( $post_id, 'YOUR_NAME_FIELD', true );
	$address = get_post_meta( $post_id, 'YOUR_ADDRESS_FIELD', true );
	$website = get_post_meta( $post_id, 'YOUR_WEBSITE_FIELD', true );

	$custom_content  = '<strong>Name: </strong>' . esc_html( $name ) . '<br />';
	$custom_content .= '<strong>Address: </strong>' . esc_html( $address ) . '<br />';

	if ( $website ) {
		$custom_content .= '<strong>Website: </strong><a href="' . esc_url( $website ) . '">Visit</a>';
	}

	return $custom_content;
}
add_filter( 'cspm_custom_infobox_description', 'my_custom_infobox_description', 10, 2 );

Related filters

Legacy docs also cover title and class customizations. Common patterns:

  • Infobox title — look for title-related cspm_* filters in Ultimate / return a custom string from post data.
  • Read more link — append HTML to your custom description.
  • CSS classes — add wrapper classes in your returned HTML for theme styling.

Example “Read more” append:

$custom_content .= '<p><a class="cspm-read-more" href="' . esc_url( get_permalink( $post_id ) ) . '">Read more</a></p>';

Tips

  • Escape output (esc_html, esc_url) — infobox HTML is front-end visible.
  • Keep content short for mobile.
  • Admin field builders (custom title/content from fields) may be enough without PHP — see Infoboxes & carousel.
