上传个人资料照片在codeigniter 3中不起作用

Question

我想让我的用户更新他们的个人资料和头像。如果我在视图中注释头像部分，并在控制器中删除。编辑进行得很好，但是如果我把上传部分放到控制器中，编辑功能就不起作用了。顺便说一下，我在codeigniter方面还是个新手。你能帮我找出我的错误吗？谢谢

      my controller                               
      public function edit($id){

        $user = $this->User_model->getUser($id);
        $data = array();
        $data['user'] = $user;
        $data1['user'] = $this->db->get_where('user', ['email' =>
        $this->session->userdata('email')])->row_array();

            'matches' => 'password not match!',
            'min_length' => 'password too short'
        ]);

        $this->form_validation->set_rules('password2', 'Password', 'required|trim|matches[password1]');

        if ($this->form_validation->run() == false) {
            $this->load->view('templates/admin/header', $data, $data1);

                if ($this->upload->do_upload('image')) {

                    $old_image = $data['user']['image'];
                    if ($old_image != 'default.jpg') {
                        unlink(FCPATH . 'assets/img/profile/' . $old_image);
                    }

                    $new_image = $this->upload->data('file_name');
                    $this->db->set('image', $new_image);
                } else {
                    echo $this->upload->display_errors();
                }
            }

            $data = array(
                'name' => htmlspecialchars($this->input->post('name', true)),
                'password' => password_hash($this->input->post('password1'), PASSWORD_DEFAULT),
            );
            $this->User_model->updateUser($id, $data);
            $this->session->set_flashdata('message', '<div class="alert alert-success" role="alert">
            User update successfully!
          </div>');
            redirect('adminprofile');
        }
    }
}

my model

    function getUser($id)
    {
        $this->db->where('id', $id);
        return $user = $this->db->get('user')->row_array();
    }


    function updateUser($id, $data)
    {
        $this->db->where('id', $id);
        $this->db->update('user', $data);
    }

Answer 1

首先，您必须在form标记中使用此after action属性：

enctype='multipart/form-data'

Answer 2

您需要像Aman所说的那样指定enctype

<form class="user" method="post" action="<?= base_url('AdminUpdateProfile/edit/'.$user['id']); ?>" enctype="multipart/form-data">

     your code here

</form>

Answer 3

正如上面的两个答案所提到的，首先您需要在表单中添加加密类型。因此，最终结果将是：

<form method="post" enctype="multipart/form-data" class="user" action="<?php echo base_url() . 'AdminUpdateProfile/edit/' . $user['id']; ?>">

如果这仍然不起作用，在我的例子中，我不得不将$_FILES索引转换为$_FILES['userfile']，因为上传库有一个问题，它对非用户文件的索引有问题。我基本上是这样做的：

$this->load->library('upload');
$config['upload_path'] = 'images/';
$config['file_ext_tolower'] = TRUE;
$config['allowed_types'] = '*';
$this->upload->initialize($config);

$_FILES['userfile']['name'] = $_FILES['image']['name'];
$_FILES['userfile']['type'] = $_FILES['image']['type'];
$_FILES['userfile']['tmp_name'] = $_FILES['image']['tmp_name'];
$_FILES['userfile']['error'] = $_FILES['image']['error'];
$_FILES['userfile']['size'] = $_FILES['image']['size'];

$this->upload->do_upload();
$data = $this->upload->data();
