NotExists

Zend\Validator\File\NotExists checks for the existence of files in specified directories.

This validator is inversely related to the Exists validator <zend.validator.file.exists>.

Supported Options

The following set of options are supported:

• directory (string|array)

  Comma-delimited string (or array) of directories.

Usage Examples

// Only allow files that do not exist in ~either~ directories
$validator = new \Zend\Validator\File\NotExists('/tmp,/var/tmp');

// ...or with array notation
$validator = new \Zend\Validator\File\NotExists(array('/tmp', '/var/tmp'));

// Perform validation
if ($validator->isValid('/home/myfile.txt')) {
    // file is valid
}

Note

This validator checks whether the specified file does not exist in any of the given directories. The validation will fail if the file exists in one (or more) of the given directories.
