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

$this->load->database();
$this->load->model('M_root');
$this->load->library('upload');
$this->load->library('form_validation');

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

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);
