Codeigniter 表单验证不起作用？

Question

我创建了包含以下字段的注册表单，

• 姓名
• 电子邮件
• 角色
• 密码
• 确认密码

但是表单验证不起作用

我尝试了很多但不起作用是我想更改 Config.php 中的任何内容我已经更改了 $config[library],$config[helper] 任何人都可以在这段代码中帮助我。提前谢谢你

这是我的控制器

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Login extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        $this->load->model('Mod_saloon');
        $this->load->helper(array('form', 'url'));
        $this->load->library(array('session', 'form_validation', 'email')); 
        $this->load->helper('url');
    }
    public function index()
    {
        $this->load->view('login');
    }
    public function show_signup()
    {
        $this->load->view('signup');
    }
    public function signup()
    {
        $config = array(
        array(
                'field' => 'name',
                'label' => 'Username',
                'rules' => 'required|min_length[5]|max_length[12]|is_unique[signup.name]'
        ),
        array(
                'field' => 'password',
                'label' => 'Password',
                'rules' => 'required',
                'errors' => array(
                        'required' => 'You must provide a %s.',
                ),
        ),
        array(
                'field' => 'cpassword',
                'label' => 'Password Confirmation',
                'rules' => 'required|matches[password]'
        ),
        array(
                'field' => 'email',
                'label' => 'Email',
                'rules' => 'required|valid_email|is_unique[signup.email]'
        )
);

$this->form_validation->set_rules($config);

        $this->form_validation->set_rules(
        'name', 'Username',
        'required|min_length[5]|max_length[12]|is_unique[signup.name]',
        array(
            'required'      => 'You have not provided %s.',
            'is_unique'     => 'This %s already exists.'
        )
        );
        $this->form_validation->set_rules('password', 'Password', 'required');
        $this->form_validation->set_rules('cpassword', 'Password Confirmation', 'required|matches[password]');
        $this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[signup.email]');
        if ($this->form_validation->run() == FALSE) 
        {
            echo "<script>alert('Validation Error');</script>";
            $this->load->view('signup');
        } 
        else 
        {
            $name = NULL;
            $role=NULL;
            $email=NULL;
            $password=NULL;
            $cpassword=NULL;

            extract($_POST);

            $signup['$name'] = $name;
            $signup['$role'] = $role;
            $signup['$email'] = $email;
            $signup['$password'] = $password;
            $signup['$cpassword'] = $cpassword;

            $this->Mod_saloon->new_signup($signup);

            $this->load->view('signup');
        }


    }
}

这是我的观点

<form action="signup" method="post">
            <div class="form-group has-feedback">
                <input type="text" class="form-control" name="name" placeholder="Name">
                <span class="glyphicon glyphicon-user form-control-feedback"></span>
            </div>
            <select class="form-control" name="role">
                <option disabled selected value> --Select the Role-- </option>
                <option value="admin">Admin</option>
                <option value="user">User</option>
            </select>
            <div class="form-group has-feedback">
                <input type="email" class="form-control" name="email" placeholder="Email">
                <span class="glyphicon glyphicon-envelope form-control-feedback"></span>
            </div>
            <div class="form-group has-feedback">
                <input type="password" class="form-control" name="password" placeholder="Password">
                <span class="glyphicon glyphicon-lock form-control-feedback"></span>
            </div>
            <div class="form-group has-feedback">
                <input type="password" class="form-control" name="cpassword" placeholder="Confirm Password">
                <span class="glyphicon glyphicon-lock form-control-feedback"></span>
            </div>
            <div class="gap"></div>
            <button type="submit" class="btn btn-primary btn-block btn-flat centered" style="width:35%;">Create User</button>
        </form>

Answer 1

我认为您的问题不在于您的表单验证不起作用...在您的控制器中，您的“注册”功能似乎无法在任何地方运行。您需要检查您的路线和用于运行的功能您需要调用的链接

$this->注册

您还需要在提交表单时调用它，因此在您的视图中，提交按钮必须具有您应该拥有的名称和值（例如：name="create_user",value="something"）注册

If ($this->input->post('create_user')){做表单验证}

Answer 2

改变动作形式

<form action="<?php echo base_url()?>index.php/Login/signup" method="post">

并且无需多次设置规则。你可以使用数组方法，也可以单独设置规则

Answer 3

您的代码需要大量修正

1. 表单标签

您需要先更改表单标签：

<form action="<?= base_url('login/signup') ?>" method="post">

1. 将您的配置数组放入配置文件夹。 在form_validation.php 中添加您的配置数组，在此文件中添加以下代码。

application/config/form_validation.php

$config = array(
    'signup_validation' => array(
        array(
                'field' => 'name',
                'label' => 'Username',
                'rules' => 'required|min_length[5]|max_length[12]|is_unique[signup.name]'
        ),
        array(
                'field' => 'password',
                'label' => 'Password',
                'rules' => 'required',
                'errors' => array(
                        'required' => 'You must provide a %s.',
                ),
        ),
        array(
                'field' => 'cpassword',
                'label' => 'Password Confirmation',
                'rules' => 'required|matches[password]'
        ),
        array(
                'field' => 'email',
                'label' => 'Email',
                'rules' => 'required|valid_email|is_unique[signup.email]'
        )
    )
    );

1. 您的控制器功能

这是你的控制器功能的代码

public function signup()
{

    if ($this->form_validation->run('signup_validation') == TRUE) {

        // Your sign up the code if validation is true. 

    } else {
        // load the view 


        //User validation_errors(); to show all your validation error at view
    }
}
