I want to display error message if no gender is selected using Codeigniter callback validation error...
My HTML Page
<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
My Controller
$this->form_validation->set_rules('gender', 'Gender', 'callback_gender');
public function gender($str)
{
if ($str == '')
{
$this->form_validation->set_message( 'gender', 'Please Choose gender' );
return FALSE;
}
else
{
return TRUE;
}
}
I tried a lot of times... Please help....
Try using $this->input->post('gender') instead of $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;
}
}
}
Or on callback $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;
}
}
}

return true;
}
else

You missed the parameter here
if($this->session->userdata() == 'admin#gmail.com')
instead it should be
if($this->session->userdata('signup_email') == 'admin#gmail.com')
I am using CodeIgniter 3 where i am trying to validate my two combo boxes.
My code is like this:
view:
<tr>
<td >
<?php $extra=' class="selectCombo"';
$busVal=array();
$busVal[]="Select";
foreach($values as $val){
$busVal[$val->bus_id]=$val->bus_no;
}
echo form_dropdown('bus_id', $busVal,set_value('bus_id'),$extra);
?>
</td>
<td><?php echo form_error('bus_id');?></td>
</tr>
<tr>
<td >
<?php
$extra=' class="selectCombo"';
$route=array();
$route[]="Select";
foreach($values as $val){
$route[$val->route_id]=$val->route_name;
}
echo form_dropdown('route_id',$route,set_value('route_id'),$extra);
?>
</td>
<td><?php echo form_error('route_id');?></td>
</tr>
My controller code is like this:
public function add()
{
$this->form_validation->set_rules('bus_id', 'Bus', 'trim|required|callback_check_Bus');
$this->form_validation->set_rules('route_id', 'Route Name', 'trim|required|callback_validate_route');
if ($this->form_validation->run() == FALSE) {
echo 'Error';
}else{
}
}
public function check_Bus($val){
if($val ==0)
{
$this->form_validation->set_message('select_validate', 'Please Select Bus.');
return false;
}
else
{
return true;
}
}
public function validate_route($val){
if($val ==0)
{
$this->form_validation->set_message('select_validate', 'Please Select Route.');
return false;
}
else
{
return true;
}
}
I get following message for both fields:
Unable to access an error message corresponding to your field name Bus.(check_Bus)
Unable to access an error message corresponding to your field name
Route Name.(validate_route)
What should i do?
Use this code working fine.
callback validation rule
callback_fieldname_check
//function name callback_fieldname_check (){
}
// Set message - fieldname_check
see code
public function add()
{
$this->form_validation->set_rules('bus_id', 'Bus', 'trim|required|callback_bus_id_check');
$this->form_validation->set_rules('route_id', 'Route Name', 'trim|required|callback_route_id_check');
if ($this->form_validation->run() == FALSE) {
$this->load->view('load_your_view');
}else{
echo "Added";
}
}
public function bus_id_check($val){
if($val ==0)
{
$this->form_validation->set_message('bus_id_check', 'Please Select Bus.');
return false;
}
else
{
return true;
}
}
public function route_id_check($val){
if($val ==0)
{
$this->form_validation->set_message('route_id_check', 'Please Select Route.');
return false;
}
else
{
return true;
}

On my login controller or view I would like to be able to see if it is possible to check if page has redirected back to login and then display bootstrap error message. I also use a MY_controller function in codeigniter
I do not want to use codeigniter session flash data message. I have my own error message as showing in code.
Is it possible to check if controller has been redirect from another controller?
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Login extends MY_Controller {
private $error = array();
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
}
public function index() {
$data['title'] = 'Administration';
$user_id = $this->session->userdata('user_id');
if (isset($user_id)) {
$this->error['warning'] = "Working";
} else {
$this->error['warning'] = "";
}
if (isset($this->error['warning'])) {
$data['error_warning'] = $this->error['warning'];
} else {
$data['error_warning'] = '';
}
$this->form_validation->set_rules('username', 'Username', 'required|callback_validate');
$this->form_validation->set_rules('password', 'Password', 'required');
if ($this->form_validation->run($this) == FALSE) {
$this->load->view('template/common/login.tpl', $data);
} else {
redirect('admin/dashboard');
}
}
public function validate() {
$this->load->library('user');
if ($this->user->login() == FALSE) {
$this->form_validation->set_message('validate', 'Does not match any of our database records');
return false;
} else {
return true;
}
}
}
MY Controller
<?php
class MY_Controller extends MX_Controller {
public function __construct() {
parent::__construct();
Modules::run('admin/error/permission/check');
}
}
Update I have tried This still displays message even though have not been redirect from another page.
Thanks to #AdrienXL for some great advice. $this->load->library('user_agent'); was the best method.
if ($this->agent->referrer()) {
$this->error['warning'] = "Working";
} else {
$this->error['warning'] = "";
}
Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

public function index() {
$data['title'] = 'Administration';
$this->load->library('user_agent');
if ($this->agent->referrer()) {
$this->error['warning'] = "Working";

When i click on my user edit button <?php echo anchor('users/edit/'. $user->user_id, '<div class="btn btn-primary"><i class="fa fa-edit"></i> Edit</div>');?>
It sends me to http://localhost/codeigniter/codeigniter-blog/admin/users/edit/1 but shows error 404 Page Not Found. '1' example is the user_id
But edit function exists. How can I make my edit function on my users controller work with the user id. So if i click on a certain user it will only update that id row information.
Model
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Model_user extends CI_Model {
protected $id;
function getAll() {
$query = $this->db->get('user');
if ($query->num_rows() > 0) {
return $query->result();
return $query->row('user_id');
return true;
} else {
return false;
}
}
public function editUser() {
}
public function getID($user_id) {
$user_query = $this->db->get('user');
if ($user_query->num_rows() == 1) {
return $user_query->row('user_id', $user_id);

May be you miss to use index.php in url
(OR)
Use below code base_url('');
<?php
$url=base_url('users/edit/'. $user->user_id);
echo anchor($url, '<div class="btn btn-primary"><i class="fa fa-edit"></i> Edit</div>');?>
I can view page now to do with routes $route['users/edit/(:num)'] = "users/users/edit/$1";
I have the controller file:- login.php
class Login extends CI_Controller {

$username = $this->input->post('username');
$password = $this->input->post('password');
$errorMsg ="";
$queryResult = $this->logins->validate($username,$password);
if($queryResult == TRUE) {
redirect ('home');
}
else {
$errorMsg ="Invalid Username or Password";
$this->load->view('login',$errorMsg);
}
}
}
view:- login.php
<script type="text/javascript">
function validatelogin(){
var x=document.forms["login"]["username"].value;
var y=document.forms["login"]["passwrd"].value;

return false;
}
/*if(x!="monisha" && y!="monisha"){
alert("Username and Password incorrect");
return false;

return true;
}

the HTML form have:-
<form name="login" id="login" action="<?php echo base_url() ?>login/success" onsubmit="return validatelogin()" method="post">
Model file logins.php is having the function, which describes function validate
class Logins extends CI_Model {

You aren't loading class "logins"
$this->load->library('Logins');
Try like this in your model
public function __construct() {
// Connecting Database
parent::__construct();
$this->load->database();
}
Please Add your model Class name into config\autoload.php file
$autoload['model'] = array('logins');
Its working fine for me,Please try it.
Load the model named Logins before you use it
$this->load->model('logins', '', TRUE);
or in autoload.php
