上传的服务器映像

问题描述

<?php
  $target_path1 = "uploads/";

  /* Add the original filename to our target path.
  Result is "uploads/filename.extension" */

  $target_path1 = $target_path1 . basename( $_FILES['uploaded_file']['name']);
  if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path1)) 
  {
      echo "The first file ".  basename( $_FILES['uploaded_file']['name'])."has been uploaded.";
  } else {
      echo "There was an error uploading the file, please try again!";
      echo "filename: " .  basename( $_FILES['uploaded_file']['name']);
      echo "target_path: " .$target_path1;
  }
?>

这有3个错误

注意：未定义指数：uploaded_file在D：\\ anddev \\项目\\网络\\ upload_test \\ upload_media_test.php第5行

注意：未定义指数：uploaded_file在D：\\ anddev \\项目\\网络\\ upload_test \\ upload_media_test.php第6行

Notice: Undefined index: uploaded_file in D:\anddev\project\web\upload_test\upload_media_test.php on line 6

注意：未定义指数：uploaded_file在D：\\ anddev \\项目\\网络\\ upload_test \\ upload_media_test.php第11行

Notice: Undefined index: uploaded_file in D:\anddev\project\web\upload_test\upload_media_test.php on line 11

我该如何解决这个问题code？

How do I fix this code ?

推荐答案

始终添加检查，以确保你实际上得到的东西，

Always add check to make sure you are actually getting something,

您可以使用试试吧像这样的：

You can make use of is_uploaded_file Try it like this:

<?php
  if(is_uploaded_file($_FILES['uploaded_file']['tmp_name']){
    //we got something, set it up
    $target_path1 = "uploads/";
    $file = basename( $_FILES['uploaded_file']['name']);        
    $full_path = $target_path1.$file; 
    //perform the upload
  if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $full_path)) {
      echo "The first file ".$file." has been uploaded.";
    } else {
      echo "There was an error uploading the file, please try again!";
      echo "filename: " .  $file;
    }
  }else{
      echo "Nothing was uploaded";
  }
?>
