Php codeigniter规则组表单验证

正如Codeigniter文档所说，我们可以在form_validation.php配置文件中创建规则集。我想我已经遵循了指令，但问题是它显示的是空的错误消息，而不是在配置数组中设置的错误消息。 我的form_validation.php配置文件

$config = array(
    'users/register' => array(
        array(
            'field' => 'user_type',
            'label' => 'User Type',
            'rules' => 'required|in_list[2,3]',
            'errors' => array(
                'in_list' => '%s Accept only agents or owners!'
            )
        ),
        array(
            'field' => 'first_name',
            'label' => 'First Name',
            'rules' => 'trim|required|alpha_numeric_spaces',
            'errors' => array(
                'required' => 'Required field.',
                'alpha_numeric_spaces' => 'Only letters, number and space are allowed for %s.'
            )
        ),
        array(
            'field' => 'last_name',
            'label' => 'Last Name',
            'rules' => 'trim|required|alpha_numeric_spaces',
            'errors' => array(
                'required' => 'Fields with red asterisk is required!',
                'alpha_numeric_spaces' => 'Only letters, number and space are allowed for %s.'
            )
        ),
        array(
            'field' => 'sex',
            'label' => 'Gender',
            'rules' => 'trim|required|in_list[male,female]',
            'errors' => array(
                'in_list' => 'Optional, %s field must be male or female.'
            )
        ),
        array(
            'field' => 'password',
            'label' => 'Password',
            'rules' =>'trim|required|min_length[6]|max_length[25]',
            'errors' => array(
                'required' => 'Required field.',
                'min_length' => '%s must be between 6-25 characters long.',
                'max_length' => '%s must be between 6-25 characters long.'
            )
        ),
        array(
            'field' => 'confirm_password',
            'label' => 'Password confirmed',
            'rules' => 'trim|required|matches[password]',
            'errors' => array(
                'required' => 'Required field.',
                'matches' => '%s doesn\'t match with password field.'
            )
        ),              
        array(
            'field' => 'email',
            'label' => 'Email',
            'rules' => 'trim|required|is_unique[users.email]|valid_email',
            'errors' => array(
                'required' => 'Required field.',
                'is_unique' => '%s is already taken.',
                'valid_email' => '%s must be valid. For example, johndoe@example.com'
            )
        )
    ),
    'users/update_address' => array(
        array(
            'field' => 'house_number',
            'label' => 'House Number',
            'rules' => 'trim|alpha_numeric_spaces',
            'errors' => array(
                'alpha_numeric_spaces' => 'Only letters, space and number are allowed for %s'
            )
        ),
        array(
            'field' => 'street_number',
            'label' => 'Street Number',
            'rules' => 'trim|alpha_numeric_spaces',
            'errors' => array(
                'alpha_numeric_spaces' => 'Only letters, space and number are allowed for %s'
            )
        ),
        array(
            'field' => 'city_id',
            'label' => 'City or Province',
            'rules' => 'trim|is_natural',
            'errors' => array(
                'is_natural' => 'Only number is allowed for %s'
            )
        ),
        array(
            'field' => 'district_id',
            'label' => 'District or Khan',
            'rules' => 'trim|is_natural',
            'errors' => array(
                'is_natural' => 'Only number is allowed for %s'
            )
        ),
        array(
            'field' => 'commune_id',
            'label' => 'Commune or sangkat',
            'rules' => 'trim|is_natural',
            'errors' => array(
                'is_natural' => 'Only number is allowed for %s'
            )
        )
    )
);

这是我的用户控制器

class Users extends AL_Controller {
    public function __construct() {
        parent::__construct();
        $this->load->helper(['url','form']);
        $this->load->model('user');
        $this->load->model('ion_auth_model');
        $this->load->library('form_validation');
    }

public function update_address() {
        header('Content-Type: application/x-json; charset=utf-8');
        if(!$this->ion_auth->logged_in()) {
            redirect(base_url(). 'users/login', 'refresh');
        } else {
            if($this->form_validation->run('update_address') == FALSE) {
                $data['errors'] = validation_errors();
                echo json_encode(array('status' => 'ERROR', 'msg' => 'Your form contains error(s). Please fix it.', 'err' => $data));
            } else {
                $user_id = $this->ion_auth->get_user_id();
                if($this->user->edit_user_address($user_id)) {
                    echo json_encode(array('status' => 'OK', 'msg' => 'Your address has been updated!'));
                } else {
                    echo json_encode(array('status' => 'ERROR', 'msg' => 'Unable to update your address. Please refresh your page and try again.'));
                }
            }
        }
    }
}

下面是显示的错误消息

{"status":"ERROR","msg":"Your form contains error(s). Please fix it.","err":{"errors":""}}

---

application/config/form_validation.php

您已经在那里定义了表单验证规则

所以你必须加载

$this->config->load('form_validation');

并尝试按以下方式访问配置规则：

$this->form_validation->set_rules($this->form_validation->set_rules($this->config->item('users/update_address'));

---

看看这是否有助于我最终找到答案。Codeigniter文档没有明确说明类/方法名关联。当我从

$this->form_validation->run('update_address') == FALSE

到

但是，下面显示的消息很难确定哪个错误对应哪个字段。如果有更好的答案，我们将不胜感激

{"status":"ERROR","msg":"Your form contains error(s). Please fix it.","err":{"errors":"<p>Only letters, space and number are allowed for House Number<\/p>\n<p>Only letters, space and number are allowed for Street Number<\/p>\n"}}

{“status”：“ERROR”，“msg”：“您的表单包含错误。请修复它。”，“err”：{“errors”：“门牌号只允许字母、空格和数字\n街道号只允许字母、空格和数字\n”}

我做了类似的事情，但我没有在配置文件中使用类/方法名关联。我做了如下工作：

form_validation.php

控制器类

class Users extends AL_Controller {
    public function __construct() {
        parent::__construct();
        $this->load->helper(['url','form']);
        $this->load->model('user');
        $this->load->model('ion_auth_model');
        $this->load->library('form_validation');
    }

public function update_address() {
        header('Content-Type: application/x-json; charset=utf-8');
        if(!$this->ion_auth->logged_in()) {
            redirect(base_url(). 'users/login', 'refresh');
        } else {
            if($this->form_validation->run('update_address') == FALSE) {
                $data['errors'] = validation_errors();
                echo json_encode(array('status' => 'ERROR', 'msg' => 'Your form contains error(s). Please fix it.', 'err' => $data));
            } else {
                $user_id = $this->ion_auth->get_user_id();
                if($this->user->edit_user_address($user_id)) {
                    echo json_encode(array('status' => 'OK', 'msg' => 'Your address has been updated!'));
                } else {
                    echo json_encode(array('status' => 'ERROR', 'msg' => 'Unable to update your address. Please refresh your page and try again.'));
                }
            }
        }
    }
}

注意：在

autoload.php

中，我添加了

$autoload['libraries']=array（'form_validation'）加载表单验证配置

希望这对你也有用。如果您面临任何其他问题，请告诉我。
尝试将var_dump（$data）
放在
echo json_encode（数组（'status'=>'ERROR'，'msg'=>'您的表单包含错误。请修复它。'，'err'=>$data））查看什么是结果数组（1）{[“错误”]=>字符串（0）”}查看没有消息显示其为空Y确实仍然为空字符串。我认为这是Codeigniter bug？你已经设置了这个
$this->form\u valiation->set\u rule（$config）不工作的家伙。项目（'$config['users/update_address']）；变量不能为单变量quote@Daroath键入
$this->form\u validation->set\u rules（$this->config->item（'users/update\u address'））查看此工作根据您的经验，我们是否可以显示如下错误消息{“状态”：“错误”，“消息”：“您的表单包含错误。请修复它。”，“错误”：{“错误”：{“门牌号”：“门牌号}，{“街道号”只允许字母、空格和数字”：”街道编号“}}只允许使用字母、空格和数字在我的应用程序中，我以不同的方式处理它。我在一个变量中存储
validation\u errors
，然后我编写了一个方法，该方法接受该变量数据并循环遍历每个项目，并在模式弹出窗口中显示错误消息。根据您的示例，对于line
echo json\u encode（数组），您将获得哪些数据（'status'=>'ERROR'，'msg'=>'您的表单包含错误。请修复它。'，'err'=>$data））；
？您可以将它粘贴到这里吗？顺便说一句，
{“status”：“ERROR”，“msg”：“您的表单包含错误。请修复它。”，“err”：{“errors”：{“house\u number”：“house number}，{“street\u number:”只允许字母、空格和数字“街道编号只允许字母、空格和数字”}}
是一个json文档。所有最终用户都没有理解它的经验。您必须为用户显示正确的验证消息。如果
json\u编码（数组（'status'=>'ERROR'，'msg'=>'您的表单包含错误。请修复它。'，'err'=>$data））
line根据您的期望返回正确的数据，然后您能告诉我接下来需要什么吗？我想要特定字段的错误，例如，如果house_number字段不正确，则返回{“house_number”：“house number只允许字母、空格和数字}”类似这样的键值对将完全修复我的问题echo json_encode（数组（'status'=>'ERROR'，'msg'=>'您的表单包含错误。请修复它'，'errors'=>$this->form_validation->ERROR_array（））；感谢@Deepak Biswal的帮助。按预期给我错误{“status”：“ERROR”，“msg”：“您的表单包含错误”。请修复它。“，”错误“：{“房屋号”：“房屋号只允许字母、空格和数字”，“街道号”：“街道号只允许字母、空格和数字”}
