P.S. Yes, I am cringing my way through this one. No, I don't know what most of these words/phrases mean.

Laravel Word Filter

A package that, once installed, allows prohibited words to be filtered out or refused. Works as standalone or with Laravel Validator. Utilizes two database tables to hold a whitelist and blacklist of acceptable and prohibited words. Can be used with Laravel's Form Validation functionality (E.G. prevent certain usernames) to refuse certain inputs and require user correction.

Installation

composer require joshuabedford/laravel-word-filter

Configure

php artisan vendor:publish

The command above will publish the appropriate files. Next, we have to install the database tables.

php artisan migrate

Now that the database tables are installed, we can seed them with data.

php artisan db:seed --class=JoshuaBedford\\LaravelWordFilter\\Database\\Seeds\\DatabaseSeeder

This should seed the database with our list of words that we consider necessary to blacklist or whitelist.

Usage

$string = app('wordFilter')->filter('something with a bad word');

The $string will contain the filtered result.

You can also define things inline

$string = app('wordFilter')->replaceWith('#')->replaceFullWords(false)->filter('something with a bad word'));

You can also use the word filter with Laravels Validation feature:

$request->validate([
    'username' => 'required|word|unique:users|max:255',
]);

Options

filter($string = string, $details = boolean) pass a string to be filtered.
- Enable details to have an array of results returned:
```
[
  "orig" => "",
  "clean" => "",
  "hasMatch" => boolean,
  "matched" => []
]
```
reset() reset replaceWith and replaceFullWords to defaults.
replaceWith(string) change the chars used to replace filtered strings.
replaceFullWords(boolean) enable to replace full words, disable to replace partial.
