CodeIgniter配置文件中的自定义验证错误消息

Question

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?

Answer 1

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.

Answer 2

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.

Answer 3

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

Answer 4

也许你应该将你的关键字段放在引号中，如：

'field' => "admin['name']"

Answer 5

Firstly, make sure you are using Codeigniter 3 not any version of Codeigniter 2.xx .

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 4 ^th 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 = '')
{
   ....

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!!!
