Magento2 use backend setting to apply custom layout in module

Question

I have written a module that has a settings page in the backend. The Module overrides a layout.xml file and uses a modified template by editing my own template path

view/frontend/layout/customer_account_create.xml

in this line of the layout file:

<block class="Magento\Customer\Block\Form\Register" name="customer_form_register" template="form/register.phtml">

But I would like to override this layout file only if the backend settings for this module is set to enabled.

I know I can add some code in the template I override to check for the setting before doing my modifications, but is there another way?

Answer 1

you can use ifconfig attribute to check admin setting,

<block class="Magento\Customer\Block\Form\Register" name="customer_form_register" template="form/register.phtml" ifconfig="passyour/config/value">

For your reference in wishlist module,

 <block class="Magento\Framework\View\Element\Html\Link\Current" ifconfig="wishlist/general/active" name="customer-account-navigation-wish-list-link">

Answer 2

Add following code to view template only if your module is enabled from backend :

<action method="setTemplate" ifconfig="tagname/general/active">
<block class="Magento\Customer\Block\Form\Register" name="customer_form_register" template="form/register.phtml">
</action>
