页面重用Codeigniter重定向表单时

Question

我正在学习使用Codeigniter 3.1.8进行开发，因为我遇到了一个问题：我遇到了一个问题：我在空白页中被重定向，并且不会显示错误。请帮忙

这是插入模型的功能

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class M_root extends CI_Model{



    function isertion_root(){
        $root=array(
            'nom_admin'=>'$user_name',
            'prenom_admin'=>'$user_prenom',
            'email_admin'=>'$user_email',
            'date_nais_admin'=>'$date_nais',
            'date_inscription_admin'=>'NOW(),false',
            'avatar_root'=>'$avatar_root',
            'password_root'=>'$pssword_root'

        );
        $this->db->insert('root', $root);
    }

    /**
     * @param $email
     * @param $password
     * @return bool
     */
    function login_root($email,$password){

        $this->db->select('*');
        $this->db->from('root');
        $this->db->where('email_admin',$email);
        $this->db->where('password_root',$password);

        if ($query=$this->db->get())
        {
            return $query->row_array();
        }
        else{
            return false;
        }
    }

    public function email_check($email_admin){

        $this->db->select('*');
        $this->db->from('root');
        $this->db->where('email_admin',$email_admin);
        $query=$this->db->get();

        if($query->num_rows()>0){
            return false;
        }else{
            return true;
        }

    }


}

这是插入控制器的功能

class Root extends CI_Controller{

    function __construct(){
        parent:: __construct();
        $this->load->database();
        $this->load->model('M_root');
        $this->load->library('upload');
        $this->load->library('form_validation');
        $this->load->helper(array('form', 'url'));
        $this->load->library('session');

    }

    public function index()
       {
        $this->load->view("register.php");
        }

        //debut fonction d'enregistrement

        public function isertion_root(){
            if($this->input->post('registersubmit')){

            $config['max_size']             = 100;
            $config['max_width']            = 1024;
            $config['max_height']           = 768;
            $this->upload->initialize($config);
            if(!empty($_FILES['filefoto']['name']))
            {
                if ($this->upload->do_upload('filefoto'))

Answer 1

您的原始代码包含许多if和no else。这意味着，如果if条件的值为假，则没有理由显示任何内容。

这是一种更好的方法。如果您将所有内容全部保留在一个函数中，并且避免了重定向，则可以在表单验证或图像上传出现错误时正确地重新填充输入字段。

public function index() {
    if ($this->input->post('registersubmit')) {
        $this->form_validation->set_rules('nom_admin', 'nom administrateur', 'trim|required|min_length[3]|max_length[23]|alpha_dash|encode_php_tags|xss_clean');
        $this->form_validation->set_rules('prenom_admin', 'prenom administrateur', 'trim|required|alpha_dash|encode_php_tags|xss_clean');
        $this->form_validation->set_rules('email_admin', 'Email administrateur', 'trim|required|valid_email|xss_clean');
        $this->form_validation->set_rules('date_nais_admin', 'Date de naissance administateur', 'trim|required');
        $this->form_validation->set_rules('avatar_root', 'Avatar root', 'trim|required');
        $this->form_validation->set_rules('password_root', 'password root', 'trim|required|min_length[8]|xss_clean');
        $this->form_validation->set_rules('conf_password', 'confirm password', 'trim|required|matches[password]');
        if ($this->form_validation->run()) {
            $this->load->library('upload');
            $config['upload_path'] = './assets/avatar-root/';
            $config['allowed_types'] = 'gif|jpg|png';
            $config['max_size'] = 100;
            $config['max_width'] = 1024;
            $config['max_height'] = 768;
            $this->upload->initialize($config);
            if ($this->upload->do_upload('filefoto')) {
                $gbr = $this->upload->data();
                //Compress Image
                $config['image_library'] = 'gd2';
                $config['source_image'] = './assets/avatar-root/' . $gbr['file_name'];
                $config['create_thumb'] = FALSE;
                $config['maintain_ratio'] = FALSE;
                $config['quality'] = '60%';
                $config['new_image'] = './assets/avatar-root/' . $gbr['file_name'];
                $this->load->library('image_lib', $config);
                $this->image_lib->resize();
                $root = array(
                    'nom_admin' => strip_tags($this->input->post('nom_admin')),
                    'prenom_admin' => strip_tags($this->input->post('prenom_admin')),
                    'email_admin' => strip_tags($this->input->post('email_admin')),
                    'date_nais_admin' => strip_tags($this->input->post('date_nais_admin')),
                    'avatar_root' => strip_tags($this->input->post('avatar_root')),
                    'password_root' => password_hash($this->input->post('password'), PASSWORD_DEFAULT)
                );
                // i have a feeling you are checking if an email already exists here
                // you can use form validations is_unique function in the rules above and forgo this
                if ($this->M_root->email_check($root['email_admin'])) {
                    $this->M_root->isertion_root($root);
                    $this->session->set_flashdata('success_msg', 'Registered successfully.Now login to your account.');
                    redirect('root/login_view');
                } else {
                    $this->session->set_flashdata('error_msg', 'bad email');
                }
            } else {
                $this->session->set_flashdata('error_msg', $this->upload->display_errors());
            }
        }
    }
    $this->load->view("register.php");
}

您只需要将表单操作更改为空白即可将其提交到同一页面。

在每个输入value中，除密码外，您还应执行以下操作：

<input type="text" name="username" value="<?php echo set_value('username'); ?>" size="50" />

这样，当用户由于输入错误的信息或其他原因而发生自然错误时，用户将不会丢失其输入。

一旦遇到同样的问题，使用此问题纠正后，请尝试此操作。

ini_set('display_errors', 1);
