Question

<?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：第5行的D：\ anddev \ project \ web \ upload_test \ upload_media_test.php中的未定义索引：uploaded_file

注意：第6行的D：\ anddev \ project \ web \ upload_test \ upload_media_test.php中的未定义索引：uploaded_file

注意：第11行的D：\ anddev \ project \ web \ upload_test \ upload_media_test.php中的未定义索引：uploaded_file

如何修复此代码？

Answer 1

放：

<?php
var_dump($_FILES);
exit;

只是在文件的开头，检查那里有什么。你的数组中有错误的键。检查输入文件的正确键是什么。

Answer 2

始终添加检查以确保您确实获得了某些内容，

您可以使用is_uploaded_file试试这样：

<?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";
  }
?>
