Codeigniter表单验证无效

Question

我正在尝试在CodeIgniter中实现表单验证。 请告诉我我的错误是什么。 我的问题是，它总是重定向到错误页面，即使我以html形式填写了所有详细信息，验证也无法正常工作，这意味着详细信息没有进入数据库。 查看页面代码

<!DOCTYPE html>
<html>
<head>
    <title>REGISTRATION</title>
</head>
<body>
<form method="POST" action="<?php echo base_url();?>Test/studentinsert" enctype="multipart/form-data">
<label>Name</label>
<input type="text" name="name" id="name"><br>
<label>Age</label>
<input type="number" name="age" id="age"><br>
<label>Address</label>
<textarea name="address" id="address"></textarea><br>
<label>User Name</label>
<input type="text" name="username" id="username"><br>
<label>Password</label>
<input type="Password" name="Password" id="Password"><br>
<label>Gender</label>
<input type="radio" name="gender" value="male">Male
<input type="radio" name="gender" value="female">Female<br>
<label>Qqualifiction</label>
<input type="text" name="quali" id="quali"><br>
<input type="file" name="certificate" id="certificate"><br>
<input type="submit" name="submit" id="submit">

</form>
<a href="<?php echo base_url()?>Test/login">LOGIN</a>
</body>
</html>

控制器页面代码

public function studentinsert()
    {
        //$this->load->helper(array('form', 'url'));

        $this->form_validation->set_rules('name', 'Name', 'required');
    $this->form_validation->set_rules('age', 'age', 'required');
    $this->form_validation->set_rules('address', 'address', 'required');
    $this->form_validation->set_rules('username', 'username', 'required');
    $this->form_validation->set_rules('password', 'password', 'required');
    $this->form_validation->set_rules('gender', 'gender', 'required');
    $this->form_validation->set_rules('quali', 'quali', 'required');
    $this->form_validation->set_rules('certificate', 'certificate', 'required');
        $config['upload_path']          = './uploads/';
        $config['allowed_types']        = '*';
        //$config['max_size']             = 100;
        $this->load->library('upload',$config);
        //$this->load->initialize($config);
        $this->upload->do_upload('certificate');
        $file="uploads/".$this->upload->data('file_name');
        $name=$this->input->post('name');
        $userid=mt_rand(100000, 999999);
        $age=$this->input->post('age');
        $address=$this->input->post('address');
        $gender=$this->input->post('gender');
        $username=$this->input->post('username');
        $hashpassword=hash('md5',$this->input->post('Password'));
        $quali=$this->input->post('quali');
        if ($this->form_validation->run() == FALSE)
                {
                        $this->load->view('registration');
                }
         else{
        $data=array('file'=>$file,'userid'=>$userid,'name'=>$name,'age'=>$age,'address'=>$address,'gender'=>$gender,'quali'=>$quali,);
        $logdata=array('userid'=>$userid,'username'=>$username,'Password'=>$hashpassword);
        $ok=$this->modeldata->insertdb($data);
        $ok1=$this->modeldata->insertlogin($logdata);
        if($ok=="success")
        {
            $this->load->view('registration');
        }
}

    }

我已经在构造函数中的控制器中加载了helper（表单，URL，表单验证）类，代码如下

function __construct()
{
    parent::__construct();
    $this->load->model('modeldata');
    // Load url helper
    $this->load->helper('url');
    $this->load->helper('form');
    $this->load->library('form_validation');

}

我修改了代码

public function studentinsert(){

    $this->form_validation->set_rules([
        [
            'field' => 'name',
            'label' => 'Name',
            'rules' => 'required'
        ],[
            'field' => 'age',
            'label' => 'age',
            'rules' => 'required'
        ],[
            'field' => 'username',
            'label' => 'username',
            'rules' => 'required'
        ],[
            'field' => 'password',
            'label' => 'password',
            'rules' => 'required'
        ],[
            'field' => 'quali',
            'label' => 'quali',
            'rules' => 'required'
        ]
    ]);
    $this->load->library('upload',[
        'upload_path' => './uploads/',
        'allowed_types'=> '*'
    ]);
    $this->upload->do_upload('certificate');
    $file="uploads/".$this->upload->data('file_name');
    $userid=mt_rand(100000, 999999);
    $name=$this->input->post('name');
    $userid=mt_rand(100000, 999999);
    $age=$this->input->post('age');
    $address=$this->input->post('address');
    $gender=$this->input->post('gender');
    $username=$this->input->post('username');
    $hashpassword=hash('md5',$this->input->post('Password'));
    $quali=$this->input->post('quali');
    if ($this->form_validation->run() == FALSE){
         $this->load->view('registration');
    }else{
        $data=array('file'=>$file,'userid'=>$userid,'name'=>$name,'age'=>$age,'address'=>$address,'gender'=>$gender,'quali'=>$quali,);
        $logdata=array('userid'=>$userid,'username'=>$username,'Password'=>$hashpassword);
        $ok=$this->modeldata->insertdb($data);
        $ok1=$this->modeldata->insertlogin($logdata);
        if($ok=="success"){
            $this->load->view('registration');
        }
    }

}

假设有一个$_POST['certificate'] （不存在，但$_FILES['certificate']确实存在）， $_FILES['certificate'] certificate和codeigniter设置了验证规则，删除了$this->form_validation->set_rules('certificate', 'certificate', 'required'); 规则并使用isset($_FILES['certificate'])代替。 然后如果找不到它，则可能重定向到错误页面
