File Validators

ImageSize

Laminas\Validator\File\ImageSize checks the size of image files. Minimum and/or maximum dimensions can be set to validate against.

Supported Options

The following set of options are supported:

• minWidth: Set the minimum image width as an integer; null (the default) indicates no minimum.
• minHeight: Set the minimum image height as an integer; null (the default) indicates no minimum.
• maxWidth: Set the maximum image width as an integer; null (the default) indicates no maximum.
• maxHeight: Set the maximum image height as an integer; null (the default) indicates no maximum.

Basic Usage

use Laminas\Validator\File\ImageSize;

// Is image size between 320x200 (min) and 640x480 (max)?
$validator = new ImageSize(320, 200, 640, 480);

// ...or with array notation
$validator = new ImageSize([
    'minWidth' => 320,
    'minHeight' => 200,
    'maxWidth' => 640,
    'maxHeight' => 480,
]);

// Is image size equal to or larger than 320x200?
$validator = new ImageSize([
    'minWidth' => 320,
    'minHeight' => 200,
]);

// Is image size equal to or smaller than 640x480?
$validator = new ImageSize([
    'maxWidth' => 640,
    'maxHeight' => 480,
]);

// Perform validation with file path
if ($validator->isValid('./myfile.jpg')) {
    // file is valid
}
