我使用以下代码，它成功地在我的本地机器上上传文件。它在我的本地计算机上显示“已成功上传”。
// Upload file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "images/" . "myFile.txt" );
if( $moved ) {
echo "Successfully uploaded";
} else {
echo "Not uploaded";
}
但是当我在我的在线服务器上使用这段代码时，它没有上传文件，只是显示消息“未上传”。
我如何知道问题是什么以及如何将实际问题显示给用户？
最佳答案
修改代码如下:
// Upload file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "images/" . "myFile.txt" );
if( $moved ) {
echo "Successfully uploaded";
} else {
echo "Not uploaded because of error #".$_FILES["file"]["error"];
}
它将为您提供以下错误代码值 1 到 8 之一:
UPLOAD_ERR_INI_SIZE = Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.
UPLOAD_ERR_FORM_SIZE = Value: 2; The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.
UPLOAD_ERR_PARTIAL = Value: 3; The uploaded file was only partially uploaded.
UPLOAD_ERR_NO_FILE = Value: 4; No file was uploaded.
UPLOAD_ERR_NO_TMP_DIR = Value: 6; Missing a temporary folder. Introduced in PHP 5.0.3.
UPLOAD_ERR_CANT_WRITE = Value: 7; Failed to write file to disk. Introduced in PHP 5.1.0.
UPLOAD_ERR_EXTENSION = Value: 8; A PHP extension stopped the file upload. PHP does not provide a way to ascertain which extension caused the file upload to stop; examining the list of loaded extensions with phpinfo() may help.
