[SOLVED] Multi-Select or Arrayed Values Validation - grimpirate - 04-19-2023
I've tried the following two pieces of code (I've hardcoded the "passed" values into the run method for the sake of clarity):
PHP Code:
$validation = \Config\Services::validation();
$validation->setRule('groups', 'Groups', ['in_list[manager,personnel]']);
if(!$validation->run(['groups' => ['manager', 'personnel']]))
return redirect()->back()->withInput();
AND:
PHP Code:
$validation = \Config\Services::validation();
$validation->setRule('groups[]', 'Groups', ['in_list[manager,personnel]']);
if(!$validation->run(['groups' => ['manager', 'personnel']]))
return redirect()->back()->withInput();
The idea here is that a user is selecting multiple values in a drop down and submitting them via form. However, the return call is always being executed denoting an error. How do I create a rule that validates an array of values for one field?
The following works, but appears an inelegant solution:
PHP Code:
$validation = \Config\Services::validation();
$validation->setRule('groups[]', 'Groups', ['in_list[manager,personnel]']);
foreach(['manager', 'personnel'] as $group)
if(!$validation->run(['groups' => $group]))
return redirect()->back()->withInput();

Thank you kenjis, I completely overlooked this section.
