When I put define('WP_DEBUG', true); in wp-config.php. And have this in my functions.php file:
function my_acf_load_value( $rows ) {
foreach ( $rows as $key => $row ) {
$column_id[ $key ] = $row[ 'field_593c04d244712' ];
}
array_multisort( $column_id, SORT_ASC, $rows );
return $rows;
}
I get the following errors on the front end:
Warning: Invalid argument supplied for foreach() in functions.php on line 110
Warning: array_multisort(): Argument #1 is expected to be an array or a sort flag in functions.php on line 113
Line 110:
foreach ( $rows as $key => $row ) {
Line 113:
array_multisort( $column_id, SORT_ASC, $rows );
Not sure how to keep this filter functional AND prevent these Warnings. What do I need to do to prevent them?
