Custom Laravel Validator for image dimensions
Extra validation rules for dealing with images in Laravel 5.

NOTE: Depending on your version of Laravel, you should install a different version of the package:
Laravel Version Package Version 4.* 1.x 5.0–5.3 2.1 5.4 2.2
Install the package through Composer.
composer require "cviebrock/image-validator"
Add the following to your
providers array in
'providers' => [ ... \Cviebrock\ImageValidator\ImageValidatorServiceProvider::class, ],
Use it like any
Validator rule. The package offers two rules for image validation:
$rules = [ 'my_image_field' => 'image_size:<width>[,<height>]', ];
The values for width and _height can be integers, or integers with a modifier prefix:
=300means the dimension must be exactly 300 pixels.
<300means the dimension must be less than 300 pixels
<=300means the dimension must be less than or equal to 300 pixels
>300means the dimension must be greater than 300 pixels
>=300means the dimension must be greater than or equal to 300 pixels
200-300means the dimension must be between 200 and 300 pixels (inclusive)
*means the dimension can be any value
If you only pass one value, it's assumed to apply to both dimensions (i.e. a square image with the given dimensions).
$rules = [ 'my_image_field' => 'image_aspect:<ratio>', ];
The value for ratio represents width ÷ height and be either a decimal or two values (width, height; both integers):
The value (or first value, if providing height and width) can also be prefixed
with a tilde
~ character, in which case the orientation does not matter:
~3,4means the image can have an aspect ratio of either 3:4 or 4:3.
Note that you may run into issues with floating point rounding.
// logo must be 300px wide by 400px tall $rules = [ 'logo' => 'required|image|image_size:300,400', ]; // logo must be less than or equal to 300x300px. $rules = [ 'logo' => 'required|image|image_size:<=300', ]; // logo must be 300px wide but can be any height $rules = [ 'logo' => 'required|image|image_size:300,*', ]; // logo must be at least 100px tall and 200-300 pixels wide (inclusive) $rules = [ 'logo' => 'required|image|image_size:>=100,200-300', ]; // logo must be square $rules = [ 'logo' => 'required|image|image_aspect:1', ]; // logo must be ready for the big screen TV :) $rules = [ 'logo' => 'required|image|image_aspect:16,9', ];
