let images = $('div.images img')
$.each(images, function( i, img ){
    let src = $(img).data('src');

    // check if img set
    if(src.length == 0){
        return;
    }

    $(img).attr('src', src);

});

let images = $('div.images img')

let src = $(img).data('src');

// check if img set

if(src.length == 0){

return;

}

// show image

$(img).attr('src', src);

});

Yii2 kartik select2 в админке(GridView) и в форме(ActiveForm)

Для Админки в GridView используем

[
    'attribute'     => 'prop_id',
    'enableSorting' => true,
    'filter'        => Select2::widget([
        'name'       => Html::getInputName($searchModel, 'prop_id'),
        'value'      => $searchModel->prop_id,
        'theme'      => Select2::THEME_DEFAULT,
        'data'       => $dataFilter['properties'],
    ]),
   'value'         => function (ShopFilter $model) {
       return $model->propertyName;
   },
    'headerOptions' => [
        'width' => 300,
    ],
],

[

'attribute' => 'prop_id',

'enableSorting' => true,

'filter' => Select2::widget([

'name' => Html::getInputName($searchModel, 'prop_id'),

'value' => $searchModel->prop_id,

'theme' => Select2::THEME_DEFAULT,

'data' => $dataFilter['properties'],

]),

'value' => function (ShopFilter $model) {

return $model->propertyName;

'headerOptions' => [

'width' => 300,

Для Формы (ActiveForm)

<?php
    echo $form->field($model,'type', ['options' => ['class' => 'col-md-2']])->widget(Select2::class, [
        'theme' => Select2::THEME_DEFAULT,
        'value'      => $model->type,
        'hideSearch' => true,
        'data' => [
            'news_company' => 'Компания',
            'news_assortment' => 'Ассортимент'
        ]
    ]);
?>

<?php

echo $form->field($model,'type', ['options' => ['class' => 'col-md-2']])->widget(Select2::class, [

'theme' => Select2::THEME_DEFAULT,

'value' => $model->type,

'hideSearch' => true,

'data' => [

'news_company' => 'Компания',

'news_assortment' => 'Ассортимент'

]

]);

htaccess Редирект для одного домена для главного

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R]

RewriteCond %{HTTP_HOST} !^www\. [NC]

RewriteCond %{HTTP_HOST} ^example.com [NC]

RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R]

Если домен начинается с example.com и без www то делаем редирект на https и www

Редирект директории на новую с вложенными директориями

RedirectMatch 301 /brand/(.*)$ /brands/$1

1	RedirectMatch 301 /brand/(.*)$ /brands/$1
