We had a custom block injected in the adminhtml section. This block is managed in a module (let's call it Vendor/Module) & it was working fine in Magento 2.1.*, following this methodology magento 2 - How to create a custom "admin" block and display it on an existing Admin page?

After upgrading to 2.2 the block has disappeared

I have checked for the concrete layout (in our case sales_order_view.xml) for any structural changes in the new version, but containers & blocks look the same as we had in 2.1.*

Any ideas for this?

This is the concrete layout file which worked fine in 2.1.*

app/code/Vendor/Module/view/adminhtml/layout/sales_order_view.xml

<?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_info"> <block class="Vendor\Module\Block\Adminhtml\Sales\Order\View\Form" name="our_unique_block_name" template="Vendor_Module::our_template.phtml"/> </referenceBlock> </body> </page>

UPDATE

Bounty: provide XML code to inject a block inside sales_order_view adminhtml layout, explaining how to place it in different sections of the page

Nero Phung answer was a good try, and led me to the real problem, looking for all sales_order_view appearances in the vendor folder

2.2 version adds Temando_Shipping module, which overrides sales_order_view layout

vendor/temando/module-shipping-m2/view/adminhtml/layout/sales_order_view.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <body> <referenceContainer name="order_tab_info"> <block class="Temando\Shipping\Block\Adminhtml\Sales\Order\View\Info" name="order_info" template="Temando_Shipping::sales/order/view/info.phtml"> <container name="extra_customer_info"/> </block> </referenceContainer> </body> </page>

So I could recover our custom block (using same XML layout as the one we used in 2.1.*) just by adding a module dependency

<module name="Vendor_Module"> <sequence> <module name="Temando_Shipping"/> </sequence> </module>

    Great work Raul, this saved me a lot of time debugging the same issue in our module on 2.2. Commented Apr 20, 2018 at 16:57

As I can see. Magento has added a new container inside block named order_info:

<block class="Magento\Sales\Block\Adminhtml\Order\View\Info" name="order_info" template="Magento_Sales::order/view/info.phtml"> <container name="extra_customer_info"/> </block>

So you can try to use this code below:

<referenceContainer name="extra_customer_info"> <block class="Vendor\Module\Block\Adminhtml\Sales\Order\View\Form" name="our_unique_block_name" template="Vendor_Module::our_template.phtml"/> </referenceContainer>

Hope it will help!

  • I have noticed that layout change in 2.2, but I wasn't sure it should affect... anyways, I have tried changing to <referenceContainer name="extra_customer_info"> but block still doesn't appear Commented Mar 12, 2018 at 10:39

Can you try with referenceContainer?

<?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> <referenceContainer name="order_info"> <block class="Vendor\Module\Block\Adminhtml\Sales\Order\View\Form" name="our_unique_block_name" template="Vendor_Module::our_template.phtml"/> </referenceBlock> </body> </page>

  • What's the purpose of the change? Why using referenceContainer to reference a block? Commented Mar 12, 2018 at 10:36
  • I use referenceBlock to modify block class (eg change template) and referenceContainer to include over blocks. And it work's Commented Mar 12, 2018 at 15:16
  • But... I believe you cannot reference a block (using its name) with a referenceContainer instruction Commented Mar 12, 2018 at 16:27
