在php中移动上传文件抛出错误localhost [复制]

The file is not uploading can anyone explain how can I debug these errors.

Warning: move_uploaded_file(): The second argument to copy() function cannot be a directory in C:\xampp\htdocs\sanigo\my-account\Registerformcontroller.php on line 21

Second one:

Warning: move_uploaded_file(): Unable to move 'C:\xampp\tmp\phpEB06.tmp' to 'images/' in C:\xampp\htdocs\sanigo\my-account\Registerformcontroller.php on line 21

my code:

$dir = 'images/'
$file = $_FILES['fileinputname']['tmp_name'];

move_uploaded_file($file , $dir );

</div>

The second argument of the move_uploaded_file needs to be a full path, including the file name.

For example:

$dir = 'images/'
$file = $_FILES['fileinputname'][tmp_name];
$new_file_name = 'foo.bar';

move_uploaded_file($file , $dir . $new_file_name);

As the php.net said : http://php.net/manual/fr/function.move-uploaded-file.php

bool move_uploaded_file ( string $filename , string $destination )

$dir = 'images/'
$file = $_FILES['fileinputname'][tmp_name];
$name = $_FILES["fileinputname"]["name"]
move_uploaded_file($file , "$dir/$name");
