Add .phtml file on all pages magento 2

Question

I want to add my custom.phtml file on the top of all pages.

How can I do this using custom module ?

Any suggestion would be appreciated.

Thanks

Answer 1

Add this code in your custom theme or module in default.xml:

app/design/frontend/Namespace/Themename/Magento_Theme/layout/default.xml

<referenceContainer name="after.body.start">
    <block class="Magento\Framework\View\Element\Template" 
           name="custom.file" 
           before="-" 
           template="Magento_Theme::html/custom.phtml"
    />
</referenceContainer>

you can also place it in your module:

app/code/Vendor/Module/view/frontend/layout/default.xml

<referenceContainer name="after.body.start">
    <block class="Vendor\Module\Block\Blockname" 
           before="-" 
           template="Vendor_Module::html/custom.phtml"
    />
</referenceContainer>

In this case the template must be saved under app/code/Vendor/Module/view/frontend/templates/html/custom.phtml

Try below steps

Step:1 Create default.xmlat location app\code\<Vendor-Name>\<Module-Name>\view\frontend\layout and add below code

<referenceContainer name="page.top">
    <block class="Magento\Framework\View\Element\Template" name="custom-block-name" template="<Vendor-Name>_<Module-Name>::page\custom.phtml"/>
</referenceContainer>

OR

 <referenceContainer name="main.content">
    <block class="Magento\Framework\View\Element\Template" name="custom-block-name" template="<Vendor-Name>_<Module-Name>::page\custom.phtml"/>
</referenceContainer>

Step:2 Create custom.phtml at location app\code\<Vendor-Name>\<Module-Name>\view\frontend\templates\page\ and add your code

for eg.

<?php 
     echo "Custom Block";
?>

Step:3 After run compile command

php bin/magento setup:di:compile

Add Custom Template file using xml block into app/design/frontend/<VendorName>/<ThemeName>/Magneto_Theme/layout/default.xml

Using referenceBlock tag you can add your custom block into header block/container

<referenceContainer name="after.body.start">
        <block class="Magento\Framework\View\Element\Template" name="custom.content" before="page-header" template="Magento_Theme::custom.phtml" />
</referenceContainer>

YOu can use page.wrapper to show before header tag.

<referenceContainer name="page.wrapper">
      <block class="Magento\Framework\View\Element\Template" name="custompage" before="-" template="{Namespace}_{Modulename}::custompage.phtml" />
 </referenceContainer>
