上传 Codeigniter [重复]

Question

这是我的代码，我的照片无法插入数据库。我不知道问题出在哪里。

实际上，我想使用 codeigniter 进行在线考试。我想用图片上传问题。但是当我尝试上传图片时，代码不起作用。

但问题成功插入数据库。只有图片上传失败

控制器：

function insert(){
	$nama_asli = $_FILES['userfile']['name'];
	$config ['file_name'] = $nama_asli;
	$config ['upload_path'] = './images/';
	$config ['allowed_types'] = 'gif|jpg|png|jpeg';
	$config ['max_size'] = '2500';
	$config ['max_width']  = '2600';
	$config ['max_height']  = '2200';
		
	
	$id_soal = '';
	$soal = $_POST['soal'];
	$a = $_POST['a'];
	$b = $_POST['b'];
	$c = $_POST['c'];
	$d = $_POST['d'];
	$kunci = $_POST['kunci'];
	$status = $_POST['status'];

	
	$this->load->library('upload', $config);
	
	if ( ! $this->upload->do_upload()){
			$error       = array('error' => $this->upload->display_errors());
			$this->load->view('admin/home/create_admin', $error);
	}
	
	else{
	$data = array('upload_data' => $this->upload->data());
	$upload_data = $this->upload->data();
	$file_name = $upload_data['file_name'];	
	$data = array(
		'id_soal' => $id_soal,
		'soal' => $soal,
		'a' => $a,
		'b' => $b,
		'c' => $c,
		'd' => $d,
		'kunci' => $kunci,
		'status' => $status,
		'foto' => $file_name,
		);
	$hasil = $this->soal_model->Simpan('soal', $data);
	if($hasil>=1){
		redirect('dashboard/index', $data);
	}
	}
	
}

型号：

class Soal_model extends Ci_Model {

  public function Ambil($where= "") {
    $data = $this->db->query('select * from soal '.$where);
    return $data;
  }
  
  public function Simpan($tabel, $data){
    $res = $this->db->insert($tabel, $data);
    return $res;
  }

有人可以帮忙吗？

Answer 1

需要添加upload::library的do_upload方法

$nama_asli                = $_FILES['userfile']['name'];

$config ['file_name']     = $nama_asli;
$config ['upload_path']   = './images/';
$config ['allowed_types'] = 'gif|jpg|png|jpeg';
$config ['max_size']      = '2500';

$this->load->library('upload', $config);

//you need to add this do_upload();
if ( ! $this->upload->do_upload('userfile')){
    $error       = array('error' => $this->upload->display_errors());

    $this->load->view('upload_form', $error);
}
else{
    $data        = array('upload_data' => $this->upload->data());
    $upload_data = $this->upload->data();
    $file_name   = $this->upload->file_name;
    .
    .
    .
    ...
}
