Adminhtml – Layout Update for Adminhtml Page

adminhtmllayout-updatetabs

I have two customer attribute that I would like to display on the "Customer view" Tab in Magento admin. I have been able to display the values from the attribute but adding:

   <tr>
        <td><strong><?php echo $this->__('Customer attribute:') ?></strong></td>
        <td><?php echo $this->htmlEscape($this->getCustomer()->getCutomerAttribute()) ?></td>
    </tr>

To adminhtml/default/default/template/customer/tab/view.phtml file. The problem is I'd prefer not to directly edit this template file and have been looking for a way to add my template without touching the default.

I have tried to add a local.xml file to override the default template but it's not working correctly…

<layout>
    <adminhtml_customer_edit>
        <reference name="content">
            <block type="adminhtml/customer_edit" name="customer_edit"></block>
        </reference>
        <reference name="head">
            <block type="adminhtml/template" name="optional_zip_countries" as="optional_zip_countries" template="directory/js/optional_zip_countries.phtml" />
            <action method="addJs"><file>mage/adminhtml/product/composite/configure.js</file></action>
            <action method="addJs"><file>varien/configurable.js</file></action>
        </reference>
        <reference name="left">
            <block type="adminhtml/customer_edit_tabs" name="customer_edit_tabs">
                <block type="adminhtml/customer_edit_tab_view" name="customer_edit_tab_view" template="path/to/customer/tab/view.phtml">
                    <block type="adminhtml/customer_edit_tab_view_sales" name="sales" template="customer/tab/view/sales.phtml" before="-" />
                    <block type="adminhtml/customer_edit_tab_view_accordion" name="accordion" />
                </block>
                <action method="addTab"><name>customer_edit_tab_view</name><block>customer_edit_tab_view</block></action>
            </block>
        </reference>

</adminhtml_customer_edit>
</layout>

I've also tried to use a layout update inside of my module but I kept getting errors

"Mage registry key "subscriber" already exists";i:1;s:2926:"#0

And then..

  Wrong tab configuration

when I tried to rewrite the block class

I'm now running out of ideas and could do with some help here please…

Many thanks!

What you should be able to do is using the following xml set the template of the view tab:

<adminhtml_customer_edit>
    <reference name="customer_edit_tab_view">
        <action method="setTemplate">
            <template>your/template/file.phtml</template>
        </action>
    </reference>
</adminhtml_customer_edit>

Magento – Magento custom module – cannot load layout file via XML

First check if the layout handle is correct.
Add this line in the controller to see the layout handle

echo $this->getFullActionName();

I have a feeling it will print something like this adminhtml_module_sync_index. This is the layout handle you have to use in the layout file.
Also, just to be save, add a name and alias to the block from the content section.
Something like this:

    <adminhtml_module_sync_index><!--put here what you get from the echo in the controller -->
        <reference name="head">
            <action method="setTitle" translate="title">
                <title>Module</title>
            </action>
        </reference>
        <reference name="content">
            <block type="module_sync/adminhtml_index" template="sync/index.phtml" as="index" name="index" />
        </reference>
    </adminhtml_module_sync_index>

Magento – How to extend backend template files in Magento 2

I'm given example here of how to extend the sales order view page. Like this, you can extend any module which one you want. Follow the Below Steps

Step 1) Enable the extension to specify the config.php file from the app/etc folder

<?php
return array (
  'modules' => 
  array (
        'Learning_RewriteSales' => 1,
  ),
);

Step 2) Create Custom.php Class in Block

<?php
namespace Learning\RewriteSales\Block\Adminhtml\Order\View;

class Custom extends \Magento\Backend\Block\Template
{

}

Step 3) Create Info.php file to extend core Info.php

<?php
namespace Learning\RewriteSales\Block\Adminhtml\Order\View;

class Info extends \Magento\Sales\Block\Adminhtml\Order\View\Info
{

}

Step 4) Create di.xml file to specify which class you were extended ( Dependency Injection )

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd">
    <preference for="Magento\Sales\Block\Adminhtml\Order\View\Info" type="Learning\RewriteSales\Block\Adminhtml\Order\View\Info"/>
</config>

Step 5) Create module.xml file to specify the setup version

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="Learning_RewriteSales" setup_version="2.0.0">
        <sequence>
            <module name="Magento_Sales"/>
        </sequence>
    </module>
</config>

Step 6) Create sales_order_view.xml file from Learning/RewriteSales/view/layout folder and write the below code

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="order_info">
            <action method="setTemplate">
                <argument name="template" translate="true" xsi:type="string">order/view/info.phtml</argument>
            </action>
        </referenceBlock>
        <referenceBlock name="order_info">
            <block class="Learning\RewriteSales\Block\Adminhtml\Order\View\Custom" name="sales_order_view_custom" template="order/view/custom.phtml" />
        </referenceBlock>
    </body>
</page>

Step 7) Create the Custom.phtml and Info.phtml file from Learning/RewriteSales/view/layout and insert below code.

Custom.phtml

<h1>Hi, I am here!</h1>

Info.phtml

First Copy the code from Magento\Sales\view\adminhtml\templates\order\view\info.phtml file and past here after that add one more line

<?php echo $block->getChildHtml('sales_order_view_custom');?>

Step 8) Finally clean the cache and see your custom code Sales Order View Page.

It's working for me. If you have any queries let me know?
