I know how to make a form validation for each of inputs in codeigniter. But is it possible to make a validation for multiple checkbox where the user should select at least one check box?
example
<input type=checkbox name=days[] >Mon
<input type=checkbox name=days[] >Tues
<input type=checkbox name=days[] >Wed
<input type=checkbox name=days[] >Thur
where the codeigniter should validate that the user should select at least one checkbox.?
HTML:
<input type=checkbox name=days[] >Mon
<input type=checkbox name=days[] >Tues
<input type=checkbox name=days[] >Wed
<input type=checkbox name=days[] >Thur
Use following code to validate above HTML :
$this->form_validation->set_rules('days[]', 'days', 'required');
Use following codes:
$this->form_validation->set_rules('days', 'days', 'required');
// Check if user has selected at least one checkbox manually
if ( isset($_POST['days'])
{
//some validation errors
}
or you can simply do it using validation rules like
$this->form_validation->set_rules('days', 'Days Label', 'required');
