Magento2 plugin to control content defined in layout

Goal:

• Recognize page's current used cms page template, read the defined page_layout file, and extract options.
• Display options at cms page, so clients can only say what the content should be. The layout is predefined and unchangeable.

ToDo's:

• Validate input and check for valid xml before storing the data
• Add wysiwyg input field support
• Multiple image upload for 1 field support
• add CDATA around input data in generated XML
• Create a sample setup based on luma theme for demo of functionality

templates

This plugin requires you to create a folder, in the [Your_Theme]/Magento_Theme/page_layout/ folder. This folder should be named: "layout_update_xml_templates" In this folder, there should be template file (.xml), don't care about the name. The content's of this file should be the contents of the layout_update_xml of a cms page.

template format:

I used regex to extract the template literals. I also check the corresponding line for the argument's information.

Editable arguments

Format for editable: %%editable: text : Title : This is the title %%. When you add this as the value of a argument, the class is aware of the following things:

• Field type is 'text'
• The label for the field is 'Title'
• The description is 'This is the title'
• The name and type of the argument it's in

If you want to define a default value, you can just type a value after the template literal (inside the argument's content).

Example of a file path to layout: [Your_Theme]/Magento_Theme/page_layout/layout_update_xml_templates/example-layout.xml

Define block wrappers

Format for block-title: %%block-title: Title of the block %% Insert that after the <referenceBlock name="block_name"> reference.

Block wrappers only have the title option

Define layout title

Format for layout title: * layout_info:title: Title of the layout Insert at the start of the document in a comment, on a separate rule exactly following the template above and below. (<!-- -->).

Layout info currently only has the title option

example template xml

<!--
/**
* layout_info:title: Title of the layout
*/
-->
<referenceContainer name="container_name">
    <referenceBlock name="block_name"><!-- %%block-title: Title of the block %% -->
		<arguments>
          <argument name="parameter_name_1" xsi:type="string">%%editable: type : Title %%Default title</argument>
          <argument name="parameter_name_2" xsi:type="string">%%editable: image : Background image %%</argument>
        </arguments>
    </referenceBlock>
</referenceContainer>
