When form_validation->run() returns FALSE, I need to know which rule didn't pass the validation test.
I know I can echo form_error() or validation_errors(), but this needs to be done before a view is loaded.
The controller needs to act differently according to which input didn't pass the validation.
Example:
public function index()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
if ($this->form_validation->run())
{
$this->load->view('something');
}
else
{
//check which rule didn't pass and act accordingly
}
}
I tried using empty on form_error('something') from within the if statement but this returns an error as empty doesn't take functions.
Also note, I can't change the error delimiters because they are used elsewhere in the script.
How would I check which rule was triggered without echoing validation_errors()?
YOU CAN USE error() for this-
public function index()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
if ($this->form_validation->run())
{
$this->load->view('something');
}
else
{
print_r($this->form_validation->error());
}
}
To display an error message using a specific field
form_error('username')

I have a input page with 3 inputs username, password, OTP. When password is wrong i want to send it 1 function and if OTP fails i want to send it other function. How can i achieve this. Below is a sample code.
public function verifyLogin() {
$data['BASE_URL'] = base_url();
$this->load->library('form_validation');
$this->form_validation->set_rules('email', 'Email', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');
$this->form_validation->set_rules('otp', 'OTP', 'trim|xss_clean|callback_check_otpNum');
if ($this->form_validation->run() == false) {
if(//passwordFails)
$this->index();
else if(//otpfails)
$this->loginPage();
}
}
Try using $this->form_validation->error_array() to get all failed validations and then equating accordingly
<?php
class Form extends CI_Controller {
public function index()
{
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->form_validation->set_rules('email', 'Email', 'required|valid_email');
$this->form_validation->set_rules('password', 'Password', 'required');
$this->form_validation->set_rules('confpassword', 'Password', 'required|matches[password]', 'callback__matcherror');
//$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
//$this->form_validation->set_rules('email', 'Email', 'required');
if ($this->form_validation->run() == FALSE)
{
$this->load->view('login');
}
else
{
$this->load->view('insert_dream');
}
}
public function _matcherror() {
$this->form_validation->set_message('_matcherror', 'Passwords should match');
return FALSE;
}
}
?>
i am a newbie to codeigniter. The above code doesnt display passwords should match error message. Is something wrong with the callback or Am i missing something.
Take a look here. You don't need to make a callback.
You are passing callback__matcherror as fourth parameter of set_rules function.It should be 3rd parameter. Use this way
$this->form_validation->set_rules('confpassword', 'Password', 'required|matches[password]|callback__matcherror');
Note
You will get this error message if your password fields match.Because you applying 3 rule there.3rd rule(call_back_function) will apply when 2nd rule is success. Your 2nd rule will valid when passwords matches.
matches[password]
will automatically check for password. You need not to use callback function callback__matcherror
I have a website build in CodeIgniter framework. The website contain a lot of forms for different purposes. I am submitting these forms directly to a controller function.
What are the things I should apply in this input before I save it to database through the model?
If I directly send this data without doing anything, what will be the security risk?
You need to use form_validation
https://ellislab.com/codeigniter/user-guide/libraries/form_validation.html
Best way will be if you will set rules for each field
like this
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
$this->form_validation->set_rules('email', 'Email', 'required');
if ($this->form_validation->run() == FALSE)
{
$this->load->view('myform');
}
else
{
$this->load->view('formsuccess');
}
And you don't need to use any special escape
Or try to understand how to use PDO in CodeIgniter

Hello all, this is my first CI project.
I have a simple form validation function in my model.
function verify_login()
{
//This method will have the credentials validation
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');
var_dump($this->form_validation->run());
die;
if ($this->form_validation->run() == FALSE) {
//Field validation failed. User redirected to login page
$this->load->view('login_view');
} else {
//Go to private area
redirect('home', 'refresh');
}
}
This only works when it's in a controller but not in a model. When I try passing the variables from the controller to the function in the model, the variables get received but won't process.
Can someone enlighten me? Thank you.
its fine to do your form validation in a model. But you want to have the validation return True or False to your controller. Not call a view. So like
// in your Model lets call it Users
function verify_login()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');
if ($this->form_validation->run() == FALSE) {
return FALSE ;
} else {
return TRUE;
}
}
// Your callback function
// in Controller
function verify(){
if( $this->users->verify_login() == FALSE ){
// $this->errormessage will be available in any view that is called from this controller
$this-errormessage = "There was an error with your Log In. Please try again." ;
$this->showLogin() ; }
else {
// set a session so you can confirm they are logged in on other pages
$this->setLoginSession($this->input->post('username', TRUE)) ;
$this->showUserHome(); }
}
Another thing to think about -- often people know their user name but mess up their password. So if you check for them separately you can adjust the error message accordingly. And if you check for user name and there are no results -- you don't need to check for password and in the error message you can tell them there is no user by that name.
My biggest recommendation to you is to not do validations like this in your model. If you're validating in your model it needs to be against a database value directly and not a form.
Please let me know if that solves your problem, if not please comment and I'll edit my answer.
UPDATE: Please ignore some of the above, as I was going off theory and not fact :)
I'll have to dig deeper into the CI core to get a good idea of what's wrong with this. Your code itself looks ok. Only thing I can see is that your callback may not exist in your model and only in your controller. Echoing the below I do not consider this a good use of the model.
The docs on validations
class Data_model extends CI_Model
{
public function rules()
{
return [
['field' => 'pertanyaan',
'label' => 'pertanyaan',
'rules' => 'required|is_unique[data.pertanyaan]'],
['field' => 'jawaban',
'label' => 'jawaban',
'rules' => 'required']
];
}
}
class Datas extends CI_Controller
{
public function add()
{
$data = $this->data_model;
$validation = $this->form_validation;
$validation->set_rules($data->rules());
if ($validation->run()) {
$data->save();
$this->session->set_flashdata('success', 'Berhasil disimpan');
}
$this->load->view("admin/data/new_form");
}
}
I am trying to use CodeIgniter's form validation class. I've used the "valid_email" parameter, as can be seen from the code below, but even when an invalid email address is entered it still passes the validation check. I tested with the string: testing123
public function login()
{
$this->form_validation->set_rules('authEmail', 'trim|required|valid_email|xss_clean');
$this->form_validation->set_rules('authPassword', 'trim|required');
$email = $this->input->post('authEmail');
$password = $this->input->post('authPassword');
if($this->form_validation->run() === FALSE) {
$this->session->set_flashdata('formValidationError', validation_errors('<p class="error">', '</p>'));
redirect('/');
} else {
// Begin authentication
}
}
Anyone have any idea what I'm doing wrong or if this is a CodeIgniter issue?
To note, I am setting a flashdata session as opposed to using:
<?php echo validation_errors(); ?>
... this is because I am doing a redirect back to the homepage (which is the login page as it's a private site).
Try this:
public function login()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('authEmail', 'Email', 'trim|required|valid_email|xss_clean');
$this->form_validation->set_rules('authPassword', 'Password', 'trim|required');
if($this->form_validation->run() !== false){
//validation passed
$email = $this->input->post('authEmail');
$password = $this->input->post('authPassword');
// Begin authentication
}
else {
$this->session->set_flashdata('formValidationError', validation_errors('<p class="error">', '</p>'));
redirect('/');
}
}
I'm just learning to use it as well, but don't you need three parameters? This is from their form validation page:
$this->form_validation->set_rules('email', 'Email', 'required');
From http://codeigniter.com/user_guide/libraries/form_validation.html#validationrules
The field name - the exact name you've given the form field.
A "human" name for this field, which will be inserted into the error message. For example, if your field is named "user" you might give it a human name of "Username". Note: If you would like the field name to be stored in a language file, please see Translating Field Names.
The validation rules for this form field.
