PHP上传文件失败

Question

我正在尝试将文件上传到我的本地服务器，但总是失败。

我所有的文件都在里面 /var/www/html/ 但是我在 html 文件夹中创建了一个名为 uploads 的文件夹，并将其权限更改为 777（我从搜索中平均获得的是最适合我需要的）

这是我的代码： index.html

<!DOCTYPE html>
<html>
<body>
<form enctype="multipart/form-data" action="upload.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>
</body>
</html>

upload.php

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES['fileToUpload']['name']);
echo "Target File: " . $target_file . "<br />";

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

Answer 1

试试这个：

index.html

 <!DOCTYPE html>
 <html>
 <body>
 <form enctype="multipart/form-data" action="upload.php" method="POST">
 Choose a file to upload: <input name="uploadedfile" type="file" /><br />
 <input type="submit" value="Upload File" />
 </form>
 </body>
 </html>

upload.php

if(isset($_FILES["uploadedfile"]["type"]) && ($_FILES["uploadedfile"]["size"] < 5000000)){
      $sourcePath = $_FILES['uploadedfile']['tmp_name'];
      $file = $_FILES['uploadedfile']['name'];
      $targetPath = "/uploads/".$file;
      if(move_uploaded_file($sourcePath,$targetPath)){
      echo "The file: ".$_FILES['uploadedfile']['name']." has been uploaded";
   }else{
      echo "Looks like it failed.";
   }
}else{
   echo "You forgot to select a file, or the file size is too large.";
}

所以它的作用是检查文件是否存在并检查它是否小于 5MB。如果是这样，它会转到上传部分。

Answer 2

你没有设置变量

$target_path

你的意思是但没用过

$target_file

相反。

Answer 3

您的输入文件是

<input name="uploadedfile" type="file" />

所以将 $_FILES['fileToUpload']['name'] 更改为 $_FILES['uploadedfile']['name']

$_FILES['uploadedfile']['name'] 必须具有文件字段Name属性的值
