Custom Laravel validation rule for checking ZIP file content.

Requirements

• Laravel 9 or higher
• PHP 8.0 or higher with zip extension enabled

Installation

You can install the package via composer:

composer require orkhanahmadov/laravel-zip-validator

Usage

Use ZipContent rule with list of required files.

use Orkhanahmadov\ZipValidator\Rules\ZipContent;

public function rules()
{
    return [
        'file' => [
            'required',
            'file',
            'mimes:zip',
            new ZipContent('thumb.jpg', 'assets/logo.png'),
        ],
    ];
}

Pass list of required files/folders to the constructor of the validator.

You can pass files as different constructor arguments or as array. If files are nested inside folders, pass relative path to file.

Validator will fail if any of the passed files does not exist in ZIP archive.

Validating maximum file size

Validator also allows checking maximum size of each file inside ZIP archive.

Simply pass file name as array key and maximum size as value:

new ZipContent(['thumb.jpg' => 100000]);

Validator in above example will look for thumb.jpg file with maximum size of 100000 bytes (100KB).

You can also mix multiple files with name-only or name+size validation:

new ZipContent(['thumb.jpg' => 100000, 'logo.png']);

Multiple files with "OR" validation

You can also pass multiple files with | symbol, if any of them exist in ZIP file validator will succeed.

new ZipContent('thumb.jpg|thumb.png|thumb.svg');

Validator in above example will look if thumb.jpg or thumb.png or thumb.svg file exists in ZIP.

Of course, you can also validate file size with "OR" validation:

new ZipContent(['thumb.jpg|thumb.png' => 100000]);

Above example will look if thumb.jpg or thumb.png file exists in ZIP and its file size is not bigger than 100000 bytes (100KB).

Important to keep in mind that when using "OR" validation with additional file size validation, validator will compare file size with the first matching element in ZIP archive.

Rejecting empty files

By default, validator only checks if file with given name exists, it will return true even if file with matching name is empty (has size of 0 bytes).

You can pass array of files as first argument and false as second argument to constructor if you want validator to reject files with 0 bytes.

new ZipContent(['thumb.jpg', 'style.css'], false);

Wildcard filename matching

Additionally, you can use wildcard filename matching with * symbol.

new ZipContent('*.jpg');

This will return true if Zip archive contains any file with .jpg extension.

Filename matching is using fnmatch function. You can use any of its patterns.
