Enhance [gvlogic] by adding user role check

[rafaehlers]

R. D. shared this code with us:

/**
 * Replace {current_user:role_is:[...]} Merge Tag
 * 
 * @param string $text Text to be parsed for Merge Tag.
 * 
 * @return string
 */
add_filter( 'gform_replace_merge_tags', function ( $text ) {

	preg_match( '#{current_user:role_is:(.*?)}#', $text, $matches );

	if ( empty( $matches ) ) {
		return $text;
	}

	$roles = explode( '||', $matches[1] );
	
	if ( array_intersect( wp_get_current_user()->roles, $roles ) ) {
		return str_replace( $matches[0], 'true', $text );
	}

	return str_replace( $matches[0], 'false', $text );
}, 1, 1 );

You need to use it like so:

[gvlogic if='{current_user:role_is:administrator}']is an admin[else]not an admin[/gvlogic]

or

[gvlogic if='{current_user:role_is:admin||meeting-participant}']welcome[/gvlogic]`

We only have this way of filtering user roles at the moment: https://docs.gravitykit.com/article/447-filtering-entries-by-wordpress-user-roles
