如何在PHP的$ _FILE数组中查看错误消息 [英] How to see the error message in $_FILE array in PHP

问题描述

我正在使用多个文件上传功能，当我将文件数组打印为时出现错误：

I am working on multiple file upload functionality where I am getting error when I print the file array as:

  print_r($_FILE);

得到错误为：

Array
(
   [name] => _agiewniki_Forrest_in_Autumn.jpg
   [type] =>
   [tmp_name] =>
   [error] => 1
   [size] => 0
)

我没有看到错误说明，仅此错误

I don't see the error description, the error only this

[error] => 1

推荐答案

您可以使用此数组显示文件上传错误消息：

You can use this array to display file-upload error messages:

$error_messages = array(
    UPLOAD_ERR_OK         => 'There is no error, the file uploaded with success',
    UPLOAD_ERR_INI_SIZE   => 'The uploaded file exceeds the upload_max_filesize directive in php.ini',
    UPLOAD_ERR_FORM_SIZE  => 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form',
    UPLOAD_ERR_PARTIAL    => 'The uploaded file was only partially uploaded',
    UPLOAD_ERR_NO_FILE    => 'No file was uploaded',
    UPLOAD_ERR_NO_TMP_DIR => 'Missing a temporary folder',
    UPLOAD_ERR_CANT_WRITE => 'Failed to write file to disk',
    UPLOAD_ERR_EXTENSION  => 'A PHP extension stopped the file upload',
);

// prints "The uploaded file exceeds the upload_max_filesize directive in php.ini"
echo $error_messages[$_FILES['error']];
