I am wanting to establish a default sort by preference when the user hasn’t specified one. I
setup to test this with:
<?php
if ( !is_set( $sort_by_preference ) ) {
$sort_by_preference = "government_wording";
}
?>
But I am receiving a Notice error:
Notice: Undefined variable: sort_by_preference in GIFI_codes.php on line 11- Line 11 is “if (
!is_set( $sort_by_preference ) ) {“What is the correct way to test this without triggering a
Notice error?Ron
