Я все еще изучаю CakePHP и хочу создать собственный помощник для тега изображения. Я уже использовал и сделал один для
, но теперь я не могу понять, как обернуть его внутри . Это должно быть решено с помощью некоторого массива, который я предполагаю, включая 3 и 1
.
Вид:
<div class="container-fluid">
<picture>
<?= $this->Picture->source($article, 'photolg_dir', 'photolg', '1200px'); ?>
<?= $this->Picture->source($article, 'photomd_dir', 'photomd', '992px'); ?>
<?= $this->Picture->source($article, 'photosm_dir', 'photosm', '768px');?>
<?= $this->Picture->img($article, 'photo_dir', 'photo'); ?>
</picture>
Пользовательский помощник, в котором я создаю
и хочу добавить

Другой помощник, где я подключаюсь между представлением и RestHelper:
<?php
namespace App\View\Helper;
use Cake\View\Helper;
use Cake\View\View;
/**
* Bild helper
*/
class PictureHelper extends Helper
{
public $helpers = ['Rest', 'Html'];
/**
* Default configuration.
*
* @var array
*/
protected $_defaultConfig = [
];
public function picture(\App\Model\Entity\Article $article)
{
}
public function source(\App\Model\Entity\Article $article, $dir, $size, $brpnt)
{
return $this->Rest->source('/' . $article->$dir . '/' . $article->$size, ['class' => 'img-fluid', 'alt' => 'Responsive image', 'media' => "(min-width: $brpnt)"]);
}
public function img(\App\Model\Entity\Article $article, $dir, $size)
{
return $this->Rest->image('/' . $article->$dir . $article->$size, ["class" => "img-fluid"], ["alt" => "Responsive image"]);
}
public function thumb(\App\Model\Entity\Article $article, $dir, $size)
{
return $this->Rest->image('/' . $article->$dir . '/' . 'thumbnail-' . $article->$size, ["class" => "img-fluid"], ["alt" => "Responsive image"]);
}
}
Большое спасибо за помощь.
