Examples

/**
 * Adjusts the font size of the certificate text based on certain conditions.
 *
 * This filter allows developers to programmatically override the default font size
 * for certificate elements. It's useful for scenarios where you might want to
 * apply a larger font size for specific certificate templates or user roles.
 *
 * @param int|float $font_size   The current font size value.
 * @param int       $cert_id     The ID of the certificate being generated.
 * @return int|float The modified font size.

add_filter( 'uo_learndash_certificate_font_size', function( $font_size, $cert_id ) {
	// Example: Increase font size by 2 points if it's a specific certificate ID
	// and the original font size is not too large already.
	if ( $cert_id === 123 && $font_size < 18 ) {
		return $font_size + 2;
	}

	// Example: Set a fixed font size for a particular certificate ID,
	// regardless of the initial value.
	if ( $cert_id === 456 ) {
		return 16;

	// If no specific conditions are met, return the original font size.
