A simple Laravel service provider for easily using HTMLPurifier inside Laravel. From their website:
HTML Purifier is a standards-compliant HTML filter library written in PHP. HTML Purifier will not only remove all malicious code (better known as XSS) with a thoroughly audited, secure yet permissive whitelist, it will also make sure your documents are standards compliant, something only achievable with a comprehensive knowledge of W3C's specifications. Tired of using BBCode due to the current landscape of deficient or insecure HTML filters? Have a WYSIWYG editor but never been able to use it? Looking for high-quality, standards-compliant, open-source components for that application you're building? HTML Purifier is for you!
Require this package with composer:
composer require mews/purifier
The service provider will be auto-discovered. You do not need to add the provider anywhere.
Require this package with composer:
composer require mews/purifier
Find the providers key in config/app.php and register the HTMLPurifier Service Provider.
'providers' => [
// ...
Mews\Purifier\PurifierServiceProvider::class,
]Find the aliases key in config/app.php and register the Purifier alias.
'aliases' => [
// ...
'Purifier' => Mews\Purifier\Facades\Purifier::class,
]Check out HTMLPurifier for Laravel 4
Use these methods inside your requests or middleware, wherever you need the HTML cleaned up:
clean(Input::get('inputname'));or
Purifier::clean(Input::get('inputname'));dynamic config
clean('This is my H1 title', 'titles');
clean('This is my H1 title', array('Attr.EnableID' => true));or
Purifier::clean('This is my H1 title', 'titles');
Purifier::clean('This is my H1 title', array('Attr.EnableID' => true));use URI filter
Purifier::clean('This is my H1 title', 'titles', function (HTMLPurifier_Config $config) {
$uri = $config->getDefinition('URI');
$uri->addFilter(new HTMLPurifier_URIFilter_NameOfFilter(), $config);
});Alternatively, in Laravel 7+, if you're looking to clean your HTML inside your Eloquent models, you can use our custom casts:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Mews\Purifier\Casts\CleanHtml;
use Mews\Purifier\Casts\CleanHtmlInput;
use Mews\Purifier\Casts\CleanHtmlOutput;
class Monster extends Model
{
protected $casts = [
'bio' => CleanHtml::class, // cleans both when getting and setting the value
'description' => CleanHtmlInput::class, // cleans when setting the value
'history' => CleanHtmlOutput::class, // cleans when getting the value
];
}To use your own settings, publish config.
php artisan vendor:publish --provider="Mews\Purifier\PurifierServiceProvider"
