Help with PHP snippet

Hi @simon1402,

The code itself is fine, the problem is almost certainly that it now exists in two places. If it’s still in your functions.php and you’ve also added it as a WPCode snippet, PHP hits the function change_query_date_value twice and throws a fatal “Cannot redeclare” error. WPCode catches that and deactivates the snippet to keep your site up, which is why it appears to work in functions.php but gets flagged in WPCode.

Here’s the same code tidied up, with the braces laid out properly and an extra check so it doesn’t warn when the value key isn’t set:

function change_query_date_value( $query_args, $block_query, $inherited ) {

      if ( ! empty( $query_args['meta_query'][0]['value'] ) ) {

              if ( 'todays_date' === $query_args['meta_query'][0]['value'] ) {
                      $query_args['meta_query'][0]['value'] = date( 'Ymd' );
              }
      }

      return $query_args;
}

add_filter( 'aql_query_vars', 'change_query_date_value', 10, 3 );

If it still gets disabled, please enable Error Logging under WPCode > Settings, re-activate the snippet, and send me the error it logs — it names the exact cause and line. Here’s how: https://wpcode.com/docs/using-snippet-error-logging/

Thanks,
