如果没有使用 Codeigniter 回调验证错误选择性别，我想显示错误消息...
<label class="control-label labeller" for="gender">Gender</label>
<input type="radio" id="gender" name="gender" value="Male">Male
<input type="radio" id="gender" name="gender" value="Female">Female
$this->form_validation->set_rules('gender', 'Gender', 'callback_gender');
public function gender($str)
{
if ($str == '')
{
$this->form_validation->set_message( 'gender', 'Please Choose gender' );
return FALSE;
}
else
{
return TRUE;
}
}
我试了很多次...请帮忙....
尝试使用$this->input->post('gender')代替$str
<?php
class Welcome extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
}
public function index() {
$this->form_validation->set_rules('gender', 'Gender', 'callback_gender');
if ($this->form_validation->run() == FALSE) {
// Load view
} else {
// Success Stuff
}
}
public function gender() {
if ($this->input->post('gender')) {
return TRUE;
} else {
$this->form_validation->set_message( 'gender', 'Please Choose gender' );
return FALSE;
}
}
}
或者回调
$this->form_validation->set_rules('gender', 'Gender', 'callback_gender[gender]');
<?php
class Welcome extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
}
public function index() {
$this->form_validation->set_rules('gender', 'Gender', 'callback_gender[gender]');
if ($this->form_validation->run() == FALSE) {
// Load view
} else {
// Success Stuff
}
}
public function gender($str) {
if ($str == '') {
$this->form_validation->set_message( 'gender', 'Please Choose gender' );
return FALSE;
} else {
return TRUE;
}
}
}
