Function in array as arguments for WP_Query

April 11, 2022 by Tarik Billa

I suspect the problem is coming from $MyCustomField which you enter as such in:

'terms' => array( $MyCustomField ),

The query consider it as only one value: '64,72', a string.

So try:

$MyCustomFieldValues = array_map( 'intval', explode( ',', $MyCustomField ) );

This will also ensure your values are integers.

Then:

'terms' => $MyCustomFieldValues,
