Hi there, wondering whether anyone could point me in the right direction... I am trying to use the form_validation class for a form that has some select boxes and some input boxes. The fields are named as arrays because the user can add more fields using a jquery script that adds a new line of fields to the form when user clicks add button. However if the post doesn't pass validation checks, i want the user to be returned to the form with the errors highlighted and the values in place with the correct value selected in the select box. Here is my view code (thats not working)
Code:
for($i = 1; $i <= 5; $i++) {
echo '<div class="hamperRow" id="row'.$i.'">';
echo form_error('hamper_items['.$i.'][quantity]');
echo '<div class="big_item_cell">';
echo '<select name="hamper_items['.$i.'][items]">';
foreach ($items as $k => $v) {
$sel = 'hamper_items['.$i.'][items]';
if ($k == '') {
echo '<option value="'.$k.'" '.set_select($sel, $k, TRUE).' >'.$v.'</option>';
} else {
echo '<option value="'.$k.'" '.set_select($sel, $k).' >'.$v.'</option>';
}
}
echo '</select>';
echo '</div>';
echo '<div class="small_item_cell">'.form_input(array('size' => '5', 'name' => 'hamper_items['.$i.'][quantity]')).'</div>';
echo '<div class="small_item_cell">'.form_dropdown('hamper_items['.$i.'][units]',$units).'</div>';
echo '<div class="clear"></div></div>';
}
The for loop is because when the page initially loads, i want the user to have 5 rows of fields (then after that when clicking a button (code not included) a new row gets added using jquery's clone function.
My controller code is as follows:
Code:
if($this->dx_auth->is_logged_in()) {
if($_POST) {
foreach ($this->input->post('hamper_items') as $k => $v) {
if ($v['items']) {
$this->form_validation->set_rules('hamper_items['.$k.'][quantity]','Quantity','required');
$this->form_validation->set_rules('hamper_items['.$k.'][units]','Units','required');
}
}
print_r($_POST);
}
if ($this->form_validation->run() == TRUE) {
print_r($_POST);
}
$data['title'] = 'Add Hamper';
$data['items'] = $this->Items_model->get_items('dropdown_array');
$data['units'] = $this->Units_model->get_units();
$this->template->add_js('js/hamperfrm.js');
$this->template->write_view('content','add_hamper',$data);
$this->template->render();
The print_r($_POST) is just for my reference really (you can see i havent finished the function off yet).
Can anyone see why the select boxes aren't being selected correctly when the form fails validation? the error messages come up fine...
Cheers,
Dan
