Ticket #50767: 50767-remove-assumption-in-code.patch

File 50767-remove-assumption-in-code.patch, 1.6 KB (added by jrf, 4 years ago)

QA: remove assumption in code Use a more stable condition. If $wpdb->get_row() is successful and the $output parameter has not been set, the output will be an instance of stdClass, so test to confirm that instead of testing against "not null".

Subject: [PATCH] QA: remove assumption in code

Use a more stable condition.
If `$wpdb->get_row()` is successful and the `$output` parameter has not been set, the output will be an instance of `stdClass`, so test to confirm that instead of testing against "not null".
