I am trying to validate an array field which is multiselect dropdown.But set_rules is completely ignoring the field.

 

$crud->set_rules('course_id[]','Course','trim|required');

 

$crud->field_type('course_id','multiselect',

                                array( "1"  => "VB", "2" => "Java", "3" => "C"));

dont think you need to use .. 

$crud->set_rules('course_id[]','Course','trim|required');

 

rather - u can simply use $crud->set_rules('course_id','Course','trim|required');

But after putting the above statement, it will always show error of course_id even after selecting it.

Please post your controller's code.

Modify file of 'system/libraries/Form_validation.php':

 

in the function "public function run($group = '')",before _execute action add codes like this:

 

...

 

if(in_array('required',$row['rules']) and is_array($row['postdata'])){
      $row['postdata'] = json_encode($row['postdata'],JSON_UNESCAPED_UNICODE);
}

 

...
$this->_execute($row, $row['rules'], $row['postdata']);
