  • Image()

Validates if the file is a valid image by checking its MIME type.

v::image()->assert('/path/to/image.gif');
// Validation passes successfully

v::image()->assert('/path/to/image.jpg');
// Validation passes successfully

v::image()->assert('/path/to/image.png');
// Validation passes successfully

All the validations above must return false if the input is not a valid file or of the MIME doesn't match with the file extension.

This validator relies on fileinfo PHP extension.
