Question

自动加载：

$autoload['libraries'] = array('database','form_validation');

控制器：

class Adminlogin extends CI_controller
{
public function new_user()
        {
            $this->form_validation->set_rules('name','name','required');
            $this->form_validation->set_rules('email','email','required|valid_email');
            $this->form_validation->set_rules('password','password','required|min_length[8]|max_length[15]');

            if ($this->form_validation->run())
            {

                $Name    = $this->input->POST('name');  
                $Email = $this->input->POST('email');
                $Password = $this->input->POST('password');

                $data = array('Name' => $Name, 'Email' => $Email, 'Password' => $Password);
                $this->load->model('login_model');              
                $this->login_model->newuser_data($data);

                //redirect('public/login_form');
                $data['message'] = 'Data Inserted Successfully';
            }
            else
            {
                echo "not done";
            }
        }

如果我从验证中删除条件，那么表格中的工作和数据以及当我在验证中应用条件时，表单不工作数据也不会在没有显示任何错误的情况下运行。

模型：

public function newuser_data($data)
    {
        $this->db->insert('users', $data);
        $query = $this->db->insert_id();
    }

视图：

 <?php echo form_open('adminlogin/new_user'); ?>
            <div class="col-md-4">
                                    <center><h3>Create User!</h3>

                <div class="form-group">
                    <?php echo form_input(['type'=>'name','name'=>'name','placeholder'=>'Name','class'=>'form-control contact-form','value'=>set_value('name')]) ?>
                    <?php echo form_error('name'); ?>
                </div>
                <div class="form-group">
                    <?php echo form_input(['type'=>'email','name'=>'email','placeholder'=>'Email','class'=>'form-control contact-form','value'=>set_value('Email')]) ?>
                    <?php echo form_error('email'); ?>
                </div>
                <div class="form-group">
                    <?php echo form_input(['type'=>'Password','name'=>'password','placeholder'=>'Password','class'=>'form-control contact-form','value'=>set_value('Password')]) ?>
                    <?php echo form_error('password'); ?> 
                </div>
                <div class="form-group text-right button-submit btn-submit">
                    <?php echo form_submit(['name'=>'submit','value'=>'Login','class'=>'btn btn-primary']) ?>
                </div>
            </div>

Answer 1

class Adminlogin extends CI_controller
{
public function new_user()
        {
            $this->form_validation->set_rules('name','name','required');
            $this->form_validation->set_rules('email','email','required|valid_email');
            $this->form_validation->set_rules('password','password','required|min_length[8]|max_length[15]');

            if ($this->form_validation->run()!=FALSE)
            {

                $Name    = $this->input->POST('name');  
                $Email = $this->input->POST('email');
                $Password = $this->input->POST('password');

                $data = array('Name' => $Name, 'Email' => $Email, 'Password' => $Password);
                $this->load->model('login_model');              
                $this->login_model->newuser_data($data);

                //redirect('public/login_form');
                $data['message'] = 'Data Inserted Successfully';
            }
            else
            {
                echo "not done";
            }
        }

if条件改变

if ($this->form_validation->run())

到

if ($this->form_validation->run()!=FALSE)

Answer 2

将此更改为

if ($this->form_validation->run())

到

if ($this->form_validation->run() != FALSE)

阅读 - Form Validation in codeigniter.com

Answer 3

更改行

if ($this->form_validation->run())

到

if ($this->form_validation->run()===TRUE)

Answer 4

更改您的陈述

发件人

if ($this->form_validation->run())

要

if ($this->form_validation->run() == TRUE)

或

if ($this->form_validation->run() != FALSE)

Answer 5

尝试使用此控制器

class Adminlogin extends CI_controller
{
public function new_user()
        {
            $this->form_validation->set_rules('name','name','required');
            $this->form_validation->set_rules('email','email','required|valid_email');
            $this->form_validation->set_rules('password','password','required|min_length[8]|max_length[15]');

            if ($this->form_validation->run()===FALSE)
            {

                echo 'Not done';
            }
            else
            {
                $Name    = $this->input->POST('name');  
                $Email = $this->input->POST('email');
                $Password = $this->input->POST('password');

                $data = array('Name' => $Name, 'Email' => $Email, 'Password' => $Password);
                $this->load->model('login_model');              
                $this->login_model->newuser_data($data);


            $data['message'] = 'Data Inserted Successfully';
        }
    }

form_validation无法在我的代码中的所有内容中工作，请帮助我
