Effortlessly test strings against any array of disallowed strings. Supports fnmatch wildcards, like * and ?.

accentinteractive/disallowlister contains both a facade Disallowlister and custom validation rule disallowlister. You can set a default array of disallowed strings in config, or add and remove disallowed strings using Disallowlister:add() and Disallowlister:remove()

This Laravel-specific package tests a string against a disallowlist. It is a Laravel implementation of the platform agnostic accentinteractive/disallowlister.

If you are looking for a framework agnostic implementation, see https://github.com/accentinteractive/disallowlister

For a list of all options, see https://github.com/accentinteractive/disallowlister#readme.

The isDisallowed() method can use wildcards, like * and ?.

Under the hood, accentinteractive/disallowtester uses fnmatch(), so you can use the same wildcards as in that php function (the globbing wildcard patterns):

• *sex* disallows sex, sexuality and bisexual.

• cycle* disallows cycle and cycles, but not bicycle.

• m[o,u]m disallows mom and mum, but allows mam.

• m?n disallows man and men, but allows moon.

• Config settings

Installation

You can install the package via composer:

composer require accentinteractive/laravel-disallowlister

Optionally you can publish the config file with:

php artisan vendor:publish --provider="Accentinteractive\LaravelDisallowlister\LaravelDisallowlisterServiceProvider" --tag="config"

Usage

Set the disallowlist in config

1. Publish the config file, running php artisan vendor:publish --provider="Accentinteractive\LaravelDisallowlister\LaravelDisallowlisterServiceProvider" --tag="config"
2. Set an default array of disalllowed strings in disallowlister.lists.default
3. If you wish to use more than one disallowlist, you can add additional arrays of disalllowed strings to disallowlister.lists, like disallowlister.lists.my_list

Use the disallowlister validation rule

By default, the validator uses the default disallow list.

// Use the disallowlist validator with the default disallowlist. 
$rules = [
    'user_input' => 'disallowlister'
];

However, you can also pass to the validator which disallowlist to use.

// Use the disallowlist validator with the my_list disallowlist. 
$rules = [
    'user_input' => 'disallowlister:default',
    'user_emails' => 'disallowlister:my_email_list'
];

Case sensitivity

By default, matching is not case sensitive. You can set case sensitivity in confg

config(['disallowlister.is_case_sensitive' => true]);

Whole word checking

By default the entire string is checked. You can set to check word for word in config.

config(['disallowlister.match_word_for_word' => true]);

Use the class directly

use Accentinteractive\LaravelDisallowlister\Facades\Disallowlister;

// Call the facade directly, using the default disallowlist
DisallowLister::isDisallowed('Earn $4,000 A DAY working from HOME!!!');

// Call the facade directly, using a specific disallowlist
DisallowLister::setDisallowList(config('disallowlister.lists.mylist'))
              ->isDisallowed('Earn $4,000 A DAY working from HOME!!!');

// Add and remove items on the facade
DisallowLister::add('foo')
              ->add(['*bar*', 'b?t'])
              ->remove('b?t')
              ->isDisallowed('Earn $4,000 A DAY working from HOME!!!');
