Magento – Change block’s template in layout XML

actionlayoutmagento2template

How to change block's template in layout XML? I tried the solution proposed in this thread:

<referenceBlock name="copyright">
    <arguments>
        <argument name="template" xsi:type="string">Vendor_Module::new.phtml</argument>
    </arguments>
</referenceBlock>

but I can't get it to work. I'm not sure if I'm doing it wrong.

If I change it to action method="setTemplate" (just like in other popular answer for this question, e.g. here):

<referenceBlock name="copyright">
    <action method="setTemplate">
        <argument name="template" xsi:type="string">Vendor_Module::new.phtml</argument>
    </action>
</referenceBlock>

all works fine and the template file is correctly changed.

So what is wrong in the first example? I'd like to avoid using action since it is marked as deprecated.

To me, the fist syntax is definitely not right, an issue has even been raised regarding it: https://github.com/magento/magento2/issues/3356

The use of the setTemplate action method is still right for now as it has not been refactored yet.

Also as an alternative, you should try:

<referenceBlock name="copyright" template="Vendor_Module::new.phtml" />

Magento – Change the default layout template programatically

Another way to this create different handler for each customer group using event controller_action_layout_load_before then on layout xml set it template.

Config.xml code is:

 <frontend>
        <events>
            <controller_action_layout_load_before>
                <observers>
                    <add_Customer_handler>
                        <class>MymoduleModelPrefix/observer</class>
                        <method>addHandler</method>
                    </add_Customer_handler>
                </observers>
            </controller_action_layout_load_before>
        </events>
  <frontend>

and Observer code is

<?php
class MymoduleNameSpace_Mymodule_Model_Observer{
 public function addHandler($observer)
    {
        $loggedIn = Mage::getSingleton('customer/session')->isLoggedIn();
    if($loggedIn):
    $groupId = Mage::getSingleton('customer/session')->getCustomerGroupId();
    //Get customer Group name
      $group = Mage::getModel('customer/group')->load($groupId);
      //echo $group->getCode();
        $observer->getEvent()->getLayout()->getUpdate()
             ->addHandle('customer_group_'.strtolower($group->getCode()));
    endif;
    }

}

According to observer code , it create handler like

General Group Customer :customer_group_general whole Group Customer : customer_group_wholesales etc.

Logic like: customer_group_LOweCaseOfCustomergroupName

  <customer_group_general>
    <reference name="root">
        <action method="setTemplate"><template>page/1column.phtml</template></action>
    </reference>
</customer_group_general>

 <customer_group_wholesales>
    <reference name="root">
        <action method="setTemplate"><template>page/2columns-left.phtml</template></action>
    </reference>
</customer_group_wholesales>

Magento – How to set Block’s template by calling a helper from layout XML

xml file

<block type="core/template" name="order_totals_wrapper" as="order_totals" template="email/order/totals/wrapper.phtml">
    <block type="sales/order_totals" name="order_totals">

Extend sales/order_totals block and add the following

protected function _construct()
{
    parent::_construct();
    $this->setTemplate(Mage::helper('Emailbygroup')->getOrderEmailTotalsTemplate());
}

The other way to do this without extending the block is on the xml file,

<block type="core/template" name="order_totals_wrapper" as="order_totals" template="email/order/totals/wrapper.phtml">
    <block type="sales/order_totals" name="order_totals">
        <action method="setTemplate"><template helper="Emailbygroup/Data/getOrderEmailTotalsTemplate"></template></action>
