How to add if condition in transactional emails

Have you ever wonder or faced situation where you want to add condition block in transactional email? If yes, we have solution for you. Please go through all the possible solution.

Solution 1: use depend tag which check whether that variable has some value or not.

{{depend shipping_company}}
  <tr>
    <td>
      <table>
        <tr>
           <td>
               <h1>Your shipment is on its way.</h1>
           </td>
           <td>
             <img src="{{media url=wysiwyg/logo-dpd.png}}" alt="" />
           </td>
         </tr>
        </table>
     </td>
   </tr>
 {{/depend}}

If you have some advance condition using block technique.

Solution 2: Block technique for advance conditioning

{{block class='Magento\\Framework\\View\\Element\\Template' 
               area='frontend' template='Codedecorator_Learn::email/shipping_company.phtml' shipping_company=$shipping_company}}

Add above block code in your email template and create new phtml template in your plugin like following:

<?php 
        if($block->getData('shipping_company') !='dpd') {
                echo $block->getData('shipping_company'); 
        }
?>

I hope above this post help you in your task.

How to Add Date Picker in Custom Form

In this post , we are going to see how we can add date picker in custom form at Backend or Frontend.

<div class="admin__field">
      <label for="delivery_date" class="admin__field-label"><?= $block->escapeHtml(__('Shipment Delivery Date')) ?></label>
         <div class="admin__field-control">
           <input name="delivery_date" type="text" class="input-text" id="delivery_date" />
       </div>
 </div>

<script>
    require([
        'jquery',
        'mage/calendar'
    ], function () {
        jQuery('#delivery_date').datepicker({
            dateFormat: 'dd/mm/yy',
            changeMonth: false,
            changeYear: false
        });
    });

How to Override comment history order in backend

We have recently worked on backed for one of customer who wants additional information in comment history form so we have override the following layout in order to make it work.

We have override both sales_order_view.xml with order_history block name.

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="order_history">
            <action method="setTemplate">
                <argument name="template" xsi:type="string">Codedecorator_Learn::order/view/history.phtml</argument>
            </action>
        </referenceBlock>
    </body>
</page>

You can now copy the history.phtml from the core and paste in your module and you can easy customize it or add new fields in your form.

Let’s us know that above code snippets helped your or not. If you have any doubt or any queries. Please do comment in our blog post.
