我有一系列相互依赖的选择列表,它们在 CI 之外可以正常工作。当我尝试在 Codeigniter 中实现它时,由于第一个选择列表未填充,或者回显代码不正确,或者我不知道是什么,我没有继续。这里的这个问题将只涉及第一个选择列表,也就是说,您不会看到任何 jquery,因为第一个直接从数据库中填充,没有任何“功能更改”。
所以这里是模块:
看法
<?php echo form_open('control_form/add_all'); ?>
<label for="f_state">State<span class="red">*</span></label>
<select id="f_state" name="f_state">
<option value=""></option>
<?php
foreach($result as $row)
{
echo '<option value="' . $row->pais_id . '">' . $row->pais_name . '</option>';
}
?>
</select>
<label for="f_city">City<span class="red">*</span></label>
<!--this will be filled based on the tree selection above-->
<select id="f_city" name="f_city" id="f_city_label">
<option value=""></option>
</select>
<label for="f_membername">Member Name<span class="red">*</span></label>
<input type="text" name="f_membername"/>
<?php echo form_close(); ?>
控制
public function add_all()
{
#Validate entry form information
$this->load->model('model_form','', TRUE);
$this->form_validation->set_rules('f_state', 'State', 'required');
$this->form_validation->set_rules('f_city', 'City', 'required');
$this->form_validation->set_rules('f_membername', 'Member Name', 'required');
$data['city'] = $this->model_form->get_state(); //gets the available groups for the dropdown
if ($this->form_validation->run() == FALSE)
{
$this->load->view('view_form_all', $data); # parece ser que vuelve a meter los mismos datos que tenia la Form
}
else
{
#Add Member to Database
$this->model_form->add_all();
$this->load->view('view_form_success');
}
}
模型
<?php
class Model_form extends CI_Model
{
function __construct()
{
// Call the Model constructor
parent::__construct();
}
function get_state()
{
$query = $this->db->query('SELECT pais_id, pais_name FROM pais');
return $query->result();
}
function add_all()
{
$v_state = $this->input->post('f_state');
$v_membername = $this->input->post('f_membername');
$data = array(
'pais_id' => NULL,
'pais_name' => $v_state
);
$this->db->insert('members', $data);
}
}
