我正在尝试在代码点火器中制作图像上传表单，但出现以下错误。
Severity: Notice
Message: Undefined index: image_file
Filename: controllers/men.php
Line Number: 23
Backtrace:
File: C:\xampp\htdocs\CodeIgniter-3.1.8\application\controllers\men.php Line: 23 Function: _error_handler
File: C:\xampp\htdocs\CodeIgniter-3.1.8\index.php Line: 315 Function: require_once
这是我的 View 、 Controller 和模型代码
1) 查看
<!DOCTYPE html>
<html>
<head>
<title>image</title>
<link rel="stylesheet" type="text/css" href="<?php echo base_url();?>/public/css/bootstrap.css">
</head>
<body>
<form method="post" action="<?php echo base_url()?>men/image_upload" id="upload_form" />
<input type="file" name="image_file">
<input type="submit" id="upload" name="upload" value="Upload" />
</form>
</body>
</html>
2) Controller
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Men extends CI_Controller
{
public function index(){
$this->load->view("imageupload");
}
public function image_upload(){
$config['upload_path']='./uploads';
$config['allowed_types']='*';
$this->load->library('upload',$config);
$this->upload->do_upload('image_file');
$image_file = $this->upload->data();
$data=array('image_file'=> $image_file['image_file']);
$this->load->model("mymodel");
$this->mymodel->imagedone($data);
}
}
?>
3) 型号
<?php
class Mymodel extends CI_Model{
function imagedone($data){
$query = $this->db->insert("image_tbl",$data);
if($query)
{
echo "File is uploaded";
}
else{
echo "failure";
}
}
}
最佳答案
此错误可能是由于表单标签缺少属性引起的，请在表单标签中添加 -> enctype="multipart/form-data"属性并尝试如下:
<form method="post" action="<?php echo base_url()?>men/image_upload" id="upload_form" enctype="multipart/form-data" />
<input type="file" name="image_file">
<input type="submit" id="upload" name="upload" value="Upload" />
</form>
