Caution

USE AT YOUR OWN RISK / Do not use in production

This plugin has been revived as an example for a conference talk at the contao conference in 2025. Whilst most, if not all the functionality is given, this extension should most likely not be used in production at all.

Contao StylePicker (formerly known as stylepicker4ward)

Description

This bundle adds the possibility to easily select a css-class from a predefined list.

Installation

Via composer

composer require contao-graveyard/stylepicker

Events

GetStylePickerEvent

Formerly known as the stylepicker4ward_getFilter Hook, the new implementation happens as a Symfony event that you can listen to. Please mind that the examples below need either autowiring to be on or need your own service tagging.

Old implementation

/*
 * HOOK to get table,PID(s),section and condition
 * in-parameter: str $table, int $id
 * out-parameter as array or FALSE if the callback does not match:
 * 		array($tbl,$pids,$sec,$cond)
 * 		str $tbl: table name, mostly the same as from the in-parameter
 * 		array $layout: ID of Pagelayout
 * 		str $sec: a section (column) identifier
 * 		str $cond: some addition condition
 */
if (isset($GLOBALS['TL_HOOKS']['stylepicker4ward_getFilter']) && is_array($GLOBALS['TL_HOOKS']['stylepicker4ward_getFilter'])) {
    foreach ($GLOBALS['TL_HOOKS']['stylepicker4ward_getFilter'] as $callback) {
        System::importStatic($callback[0]);
        $result = $this->{$callback[0]}->{$callback[1]}($table, $id);
        if (is_array($result)) {
            [$table, $layout, $section, $condition] = $result;
            break;
        }
    }
}

Defining in a class

<?php

namespace App\EventListener

use ContaoGraveyard\StylePickerBundle\Event\GetStylePickerFilterEvent;
use Symfony\Component\EventDispatcher\Attribute\AsEventListener;

#[AsEventListener]
class StylePickerEventListener
{
    public function __invoke(GetStylePickerFilterEvent $event): void
    {
        if ($event->getTable() !== 'my_table') {
            return;
        }

        $event->setLayout(213);
        $event->setCondition('foobar');
        $event->setSection('your_section');
    }
}

Directly on the method

<?php

namespace App\EventListener

use ContaoGraveyard\StylePickerBundle\Event\GetStylePickerFilterEvent;
use Symfony\Component\EventDispatcher\Attribute\AsEventListener;

class MyMultiListener
{
    #[AsEventListener]
    public function onGetStylePickerFilterEvent(GetStylePickerFilterEvent $event): void
    {
        // ...
    }
}
