Integration

As extension developer

If you provide an extension with custom content elements or frontend modules which might require consent to be rendered you can register a plugin which provides extra information. You need to tag it as hofff_contao_consent_bridge.plugin.

namespace Your\Bundle;

use Hofff\Contao\Consent\Bridge\Bridge;
use Hofff\Contao\Consent\Bridge\Bridge\Plugin;
use Hofff\Contao\Consent\Bridge\Render\RenderInformation;

class MyPlugin implements \Hofff\Contao\Consent\Bridge\Plugin
{
    public function load(Bridge $bridge): void
    {
        $bridge->supportFrontendModule('custom_1', RenderInformation::autoRenderWithoutPlaceholder());
        $bridge->supportFrontendModule('custom_2', RenderInformation::autoRenderWithPlaceholder('custom_placeholder_template'));
        $bridge->supportFrontendModule('custom_3', RenderInformation::customRender());

        $bridge->supportContentElement('custom_1', RenderInformation::autoRenderWithoutPlaceholder());
        $bridge->supportContentElement('custom_2', RenderInformation::autoRenderWithPlaceholder('custom_placeholder_template'));
        $bridge->supportContentElement('custom_3', RenderInformation::customRender());
    }
}

Then there will be a new legend where you can assign a consent id to your configuration and the rendering of the html output will automatically adjusted depending the requirements of the consent tool.

As consent tool developer

As consent tool developer you need to implement the interface Hofff\Contao\Consent\Bridge\ConsentTool and tag it as hofff_contao_consent_bridge.consent_tool in the dependency injection container.s
