I'm using Codeigniter form validation by config (not setting rules manually). What I need, is setting required rule depending on the other field. For example, Imagine we have the following rules:
'user' => array(
array(
'field' => 'user[phone]',
'rules' => 'required'
),
array(
'field' => 'user[email]',
),
array(
'field' => 'user[foo]',
//'rules' => 'required'
)
),
foo input must be required based on email field.
Note: It can be done with callback function, but it makes it a bit difficult in big applications. Any idea?
In your APPPATH.'config/form_validation.php' file set separated rule arrays
$config = array(
'yes_email' => array(
array(
'field' => 'user[phone]',
'rules' => 'required'
),
array(
'field' => 'user[email]',
),
array(
'field' => 'user[foo]',
'rules' => 'required'
)
),
'no_email' => array(
array(
'field' => 'user[phone]',
'rules' => 'required'
),
array(
'field' => 'user[email]',
),
array(
'field' => 'user[foo]',
)
),
);
, then in controller use what ever rule set you want. In example
if ($this->form_validation->run($rule) == FALSE) {
$this->load->view('myform');
} else {
$this->load->view('formsuccess');
}
Before this check, you should determine what rule you need there with something like:
$rule = 'no_email'; // set default value
switch($this->input->post('email')) {
case false:
break;
default:
$rule = 'yes_email'; // email has been posted / needed by app etc.
}

I am using codeigniter form validation to validate user data when creating new user. I want to add some sort of password criteria for example password must have
at least one capital letter, a number, and one of !, #, #, $ etc) and there have to be 6-25 characters.
This is the array that I am using for validation rules:
$config = array(
array(
'field' => 'title',
'label' => 'Title',
'rules' => 'trim|required'
),
array(
'field' => 'firstname',
'label' => 'First Name',
'rules' => 'trim|required|min_length[2]|max_length[100]|xss_clean'
),
array(
'field' => 'lastname',
'label' => 'Last Name',
'rules' => 'trim|required|min_length[2]|max_length[100]|xss_clean'
),
array(
'field' => 'phone',
'label' => 'Telephone',
'rules' => 'trim|required|intiger|min_length[11]|max_length[11]|xss_clean'
),
array(
'field' => 'email',
'label' => 'Email',
'rules' => 'trim|required|valid_email|is_unique[ci_user.email]|matches[conf_email]|xss_clean'
),
array(
'field' => 'conf_email',
'label' => 'Confirm Email',
'rules' => 'trim|required|valid_email|xss_clean'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'trim|required|min_length[6]|max_length[25]|matches[conf_password]|xss_clean'
),
array(
'field' => 'conf_password',
'label' => 'Confirm Password',
'rules' => 'trim|required|xss_clean'
));
Can someone please guide me on how to achieve what I need. Thank you
you can setup call back function to check password strong validation. and call this function callback_is_password_strong in this line of your code.
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'trim|required|min_length[6]|max_length[25]|matches[conf_password]|xss_clean|callback_is_password_strong'
),
and if you look this function will return true or false and password array rule key is validated only when it returns true
public function is_password_strong($password)
{
if (preg_match('#[0-9]#', $password) && preg_match('#[a-zA-Z]#', $password)) {
return TRUE;
}
return FALSE;
}
Using callback function
public function check_strong_password($str)
{
if (preg_match('#[0-9]#', $str) && preg_match('#[a-zA-Z]#', $str)) {
return TRUE;
}
$this->form_validation->set_message('check_strong_password', 'The password field must be contains at least one letter and one digit.');
return FALSE;
}
Usage
$this->form_validation->set_rules('adminPassword', 'password', 'required|min_length[8]|max_length[25]|callback_check_strong_password');
I'm new to CodeIgniter (v 3.0.0) (coming from CakePHP), and I'm trying to set custom validation error messages to one of my forms. I'm using a config file to store all my validation rules, as explained here. This is my application/config/form_validation.php file:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
$config = array(
'appointments/signup' => array(
array(
'field' => 'admin[name]',
'label' => 'Name',
'rules' => 'required',
'errors' => array(
'required' => 'Please tell us your %s',
),
),
array(
'field' => 'admin[email]',
'label' => 'Email',
'rules' => 'required|valid_email|is_unique[users.email]',
'errors' => array(
'required' => 'Please enter your %s address',
'valid_email' => 'Please enter a valid email address',
'is_unique' => 'That email is already taken. Forgot your password?'
)
),
array(
'field' => 'admin[username]',
'label' => 'Username',
'rules' => 'required|min_length[4]|max_length[25]|is_unique[user_settings.username]',
'errors' => array(
'required' => 'Please choose a %s',
'min_length' => '%s must me at least 4 characters long',
'max_length' => '%s cannot exceen 25 characters',
'is_unique' => '%s is already taken :('
)
),
array(
'field' => 'admin[phone_number]',
'label' => 'Phone number',
'rules' => 'min_length[0]',
),
array(
'field' => 'admin[password]',
'label' => 'Password',
'rules' => 'required|min_length[8]',
'errors' => array(
'required' => 'Please choose a %s',
'min_length' => '%s must be at least 8 characters long'
)
),
array(
'field' => 'admin[passconf]',
'label' => 'Password',
'rules' => 'required|matches[admin[password]]',
'errors' => array(
'required' => 'Please re-type your %s',
'matches' => '%ss do not match'
)
),
array(
'field' => 'company[company_name]',
'label' => 'Organization\'s Name',
'rules' => 'required',
'errors' => array(
'required' => 'Please tell us your %s',
)
),
),
);
As you can see, I'm trying to set custom validation feedback using the errors array, as detailed here. But I still see the global default The <field name> field is required. message.
Is there a way to set custom validation messages in the config file, without having to edit the global default file?
Try to change the order of the keys in your array, something like this:
'appointments/signup' => array(
array(
'field' => 'admin[name]',
'label' => 'Name',
'errors' => array(
'required' => 'Please tell us your %s',
),
'rules' => 'required',
)
The exact same problem was happening to me, and after some debugging on the core classes, I was feeling stupid enough to try this.
Looks like a bug, but I didn't go any further.
I'm using version 3.0.1.
UPDATE
I was wrong, if this was happening on v 3.0.0, is not happening on 3.0.1. What I described above was me making a mistake with parentheses in my array.
Everything is working as it should.
validation error messages comes from language files because each language has own error messages
I think you can change validation error messages in language files.
Please try use helpers under application/helpers and define your validation errors in function. Then try accessing the validation rules or use errors under application/errors. please refer https://ellislab.com/codeigniter/user-guide/general/helpers.html
Firstly, make sure you are using Codeigniter 3 not any version of Codeigniter 2.x.x.
I was in trouble with the same issue and found that the errors array is available in Codeigniter 3 version and the config rules are set in form_validation's run() method, so if you see the set_rules function in Form_validation.php file you will see the 4th parameter which is errors
/**
* Set Rules
*
* This function takes an array of field names and validation
* rules as input, any custom error messages, validates the info,
* and stores it
*
* #param mixed $field
* #param string $label
* #param mixed $rules
* #param array $errors
* #return CI_Form_validation
*/
public function set_rules($field, $label = '', $rules = array(), $errors = array())
{
.....
And which is not available in 2.2-stable version, see Form_validation.php, and see the piece of code which shows the difference
/**
* Set Rules
*
* This function takes an array of field names and validation
* rules as input, validates the info, and stores it
*
* #access public
* #param mixed
* #param string
* #return void
*/
public function set_rules($field, $label = '', $rules = '')
{
....
May be you should put your key field within inverted commas like:
'field' => "admin['name']"
Do not try use direct call to signup(your_func_name).
$this->form_validation->run('signup')
Use alternate method - (controller_name/function_name)
$config = array(
'Authenticate_user/signup' => array(
array(
'field' => 'firstname',
'label' => 'Name',
'rules' => 'trim|required'
),
array(
'field' => 'useremail',
'label' => 'Email ID',
'rules' => 'trim|required|callback_check_unique_emailid'
),
array(
'field' => 'gender',
'label' => 'Gender',
'rules' => 'trim|required'
),
array(
'field' => 'age',
'label' => 'Age',
'rules' => 'trim|required'
),
array(
'field' => 'passcode',
'label' => 'Password',
'rules' => 'trim|required'
),
array(
'field' => 'confirmpasscode',
'label' => 'Confirm Password',
'rules' => 'required|matches[passcode]',
'errors' => array(
'matches[passcode]' => 'Only number is allowed'
)
),
array(
'field' => 'usertype',
'label' => 'User Type',
'rules' => 'trim|required'
),
array(
'field' => 'country',
'label' => 'Country',
'rules' => 'trim|required'
),
array(
'field' => 'state',
'label' => 'State',
'rules' => 'trim|required'
),
array(
'field' => 'category',
'label' => 'Category',
'rules' => 'required'
)
));
then call like it,
if ($this->form_validation->run() == FALSE) {... }
cheers!!!
I´m validating a form with the codeigniter form validation class and an own form_validation file in the configuration. Additionally I´m using the language class for translation. That works perfect in view and controller but I need to get the translation also in the config/form_validation.php.
Has anybody an idea how I can do that?
Excerpt of the config/form_validation.php
$config = array(
/**
* Login form
*/
'auth/login' => array(
array(
'field' => 'email',
'label' => 'E-Mail address', <--- HERE I´D LIKE TO USE THE TRANSLATIONS
'rules' => 'trim|required|xss_clean|valid_email'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'trim|required|xss_clean'
)
),
.....
Thanks for your ideas,
best Michael
You can use the 'lang' prefix like..
'auth/login' => array(
array(
'field' => 'email',
'label' => 'lang:email_address_label',
'rules' => 'trim|required|xss_clean|valid_email'
)
I'd like some help please.
This is the array that holds all the validation on a contact form
class Contact_Form extends CI_Controller
{
private $_validation = array(
'fullname' => array(
'field' => 'fullname',
'label' => 'Fullname',
'rules' => 'trim|required|max_length[255]'
),
'email' => array(
'field' => 'email',
'label' => 'Email Address',
'rules' => 'trim|required|max_length[255]|valid_email'
),
'phone' => array(
'field' => 'phone',
'label' => 'Phone',
'rules' => 'trim|max_length[10]|integer'
),
'message' => array(
'field' => 'message',
'label' => 'Message',
'rules' => 'trim|required'
),
'captcha' => array(
'field' => 'captcha',
'label' => 'Security Code',
'rules' => 'trim|required|callback_validate_captcha'
)
);
// This is the part where I validate my contact form inside a method
$this->load->library('form_validation');
$this->form_validation->set_rules($this->_validation);
if ($this->form_validation->run() === true) {
echo 'works!';
}
This is the callback function that validates the captcha
public function callback_validate_captcha($str) {
$post_captcha = $this->input->post('captcha');
$set_captcha = $this->session->userdata('captcha');
if (strcmp($set_captcha, $post_captcha) !== 0) {
$this->form_validation->set_message('validate_captcha', '%s is wrong');
return false;
}
return true;
}
If i hit submit on an empty form I get the error that idicates that captcha is a required field, but if i submit a wrong code i don't get any error at all, which means that the callback is being ignored.
I tried to change my if statement
// change this (althought i feel its more correct)
if (strcmp($set_captcha, $post_captcha) !== 0)
// to this
if ($set_captcha != $post_captcha)
but the problem remains. Any ideas what's wrong?
you are making major mistake you have to make function validate_captcha instead of callback_validate_captcha.
Because callback is form keyword to call a function just try and bingo
