File Validators

Count

Laminas\Validator\File\Count allows you to validate that the number of files uploaded matches criteria, including a minimum number of files and/or a maximum number of files.

Supported Options

The following options are supported:

  • min: The minimum number of uploaded files acceptable; null is equivalent to 0, indicating no minimum.
  • max: The maximum number of uploaded files acceptable; null is equivalent to no maximum.

Basic Usage

$validator = new Laminas\Validator\File\Count([
    'min' => 1,
    'max' => 5,
]);

// Setting to the $_FILES superglobal; could also use the laminas-http
// request's `getFiles()` or PSR-7 ServerRequest's `getUploadedFiles()`.
$files = $_FILES;

if ($validator->isValid($files)) {
    // Received between 1 and 5 files!
}
