Magento 2: Adding a template file before the page footer (invalid template file error)

Question

I am trying to add a template file above my footer to show a subscribe form.

In my template I have created a file app/design/frontend/<vendor>/<theme>/Magento_Theme/layout/default.xml. Here's the contents:

                <block class="Magento\Framework\View\Element\Template"
                    name="prefooter.subscribe"
                    template="Magento_Theme::footer-subscribe.phtml" />

                <block class="Magento\Cms\Block\Block" name="ofihudui">
                  <action method="setTitle"><argument name="title" xsi:type="string">TEST</argument></action>
                  <action method="setBlockId"><argument name="block_id" xsi:type="string">test</argument></action>
                </block>

            </container>
        </referenceContainer>
    </body>
</page>

I have also created the file app/design/frontend/<vendor>/<theme>/Magento_Theme/template/footer-subscribe.phtml and here's the contents:

<h1>test</h1>

The page will show the second block fine, but when I try to add the prefooter.subscribe block Magento gives me this error:

1 exception(s):
Exception #0 (Magento\Framework\Exception\ValidatorException): Invalid template file: 'Magento_Theme::footer-subscribe.phtml' in module: '' block's name: 'prefooter.subscribe'

Is it because I have the file in the wrong place? I'm not sure what to do here, it seems like it should work to me.

Answer 1

I think u should try naming the phtml file footer_subscribe.phtml instead of footer-subscribe.phtml

Answer 2

app/design/frontend/{vendor}/{theme}/Magento_Theme/templates/html/myfooter-subscribe.phtml

<block class="Magento\Framework\View\Element\Template" name="my-custom-footersubscribe" template="Magento_Theme::html/myfooter-subscribe.phtml" />

Deploy the static-content, then Clean the cache.

php bin/magento cache:clean

php bin/magento setup:static-content:deploy -f

Important : check your phtml content, if you are calling some $block function from a module, it will not work.

In this case you create this phtml in that module then you call it in your layout like this:

<block class="{Vendor}\{Modulename}\Block\{Blockname}" name="my-custom-footersubscribe" template="Vendor_Modulename::html/myfooter-subscribe.phtml" />

Answer 3

As per your query i found that your problem is with below code.

<block class="Magento\Framework\View\Element\Template"
                name="prefooter.subscribe"
                template="Magento_Theme::footer-subscribe.phtml" />

Because, you specify block name name="prefooter.subscribe" but there is a no block found like this name.

And if you want to change the position of your block then you can use <move element="form.subscribe" destination="footer" before="-"/> like this.

I hope it works.
