The service provider will be auto-discovered. You do not need to add the provider anywhere.

Usage

Use these methods inside your requests or middleware, wherever you need the HTML cleaned up:

clean($request->get('inputname'));

or

ApplicationContext::getContainer()->get(Purifier::class)->clean($request->get('inputname'));

dynamic config

clean('This is my H1 title', 'titles');
clean('This is my H1 title', array('Attr.EnableID' => true));

or

ApplicationContext::getContainer()->get(Purifier::class)->clean('This is my H1 title', 'titles');
ApplicationContext::getContainer()->get(Purifier::class)->clean('This is my H1 title', array('Attr.EnableID' => true));

use URI filter

ApplicationContext::getContainer()->get(Purifier::class)->clean('This is my H1 title', 'titles', function (HTMLPurifier_Config $config) {
    $uri = $config->getDefinition('URI');
    $uri->addFilter(new HTMLPurifier_URIFilter_NameOfFilter(), $config);
});

Alternatively, if you're looking to clean your HTML inside your Eloquent models, you can use our custom casts:

<?php

namespace App\Models;

use Hyperf\DbConnection\Model\Model;
use FriendsOfHyperf\Purifier\Casts\CleanHtml;
use FriendsOfHyperf\Purifier\Casts\CleanHtmlInput;
use FriendsOfHyperf\Purifier\Casts\CleanHtmlOutput;

class Monster extends Model
{
    protected array $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
    ];
}

Configuration

To use your own settings, publish config.

php bin/hyperf.php vendor:publish friendsofhyperf/purifier
