I am building an HTML form with a set of checkboxes for selecting multiple categories using this format:
<input type="checkbox" name="category" />
So, when I post and
print_r($_POST) to view the variable and values I get:
Array (  => on  => on  => on )
Once I run
$this->form_validation->run(); the categories array becomes "Array" as a string. I believe I have narrowed it down to "prep_for_form" function in the system/libraries/Form_validation.php file, but it seems like the recursive function is working correctly.
Thank you in advance.
I figured it out. When using the
$this->form_validation->set_rules() method, in the validation rules (third parameter) I set it to
trim|required. I guess the trim function treats the actual Array like a string "Array" and trims the word. I simply removed the "trim" rule from my validation rules. e.g.
$this->form_validation->set_rules('category', 'categories', 'trim|required'); // when parsing an array (set of checkboxes, radio buttons, etc.) // - remove the "trim" validation $this->form_validation->set_rules('category', 'categories', 'required');
I hope others find this useful.
