Working with file uploads¶

Manual¶

Sometimes it is needed that a user uploads a file. To handle incoming files, response has the upload() method. It returns a z_upload object which has more methods to handle with uploads.

$upload = $res->upload();
if ($upload->upload($_FILES["file"], "uploads/", FILE_SIZE_100GB, ["txt", "jpg", "png"])) {
    $res->error();
}

$fileId = $upload->fileId;

$file is the file in $_FILES.
$uploadDir is the directory to place the file in. Ending with /.
$maxSize is the max file size. For some values there are already constants in the framework.
$typeArray array of accepted file types.

Using Z-Forms¶

When using Z-Forms, files will be stored and error feedback automatically goes back to the user. For file uploads there is the special rule file().

(new FormField("file")) -> file(FILE_SIZE_1MB, ["txt", "jpg", "png"])
