Summary of Changes

In form xml files you can add useglobal="true", this will then extend the field to show the value for the field in the matching component options.

This PR extends the useglobal to not only use the component options but also a plugins options.

This will create the possibility to have the same functionality it had but then for (global) plugin parameters.

This is a POC on the 'text' field to see if there is interest in this change, if so I can further extend it to the other fields that have the useglobal functionality:

• MailtemplateLayoutField
• ComponentLayoutField
• ListField
• NumberField
• PluginsField

Testing Instructions

on a formfield you can now have the following useglobal settings:

• useglobal="true": this will take the configured field value from the component
• useglobal="plg_system_xyz": this will take the configured value from the plugin with type 'system' and name 'xyz'

in file ./administrator/components/com_content/forms/article.xml change field "float_into" to use com_content as useglobal value:

			<field
				name="float_intro"
				type="text"
				label="COM_CONTENT_FIELD_IMAGE_CLASS_LABEL"
				description="COM_CONTENT_FIELD_IMAGE_CLASS_DESC"
				useglobal="com_content"
				validate="CssIdentifier"
			/>

after this field add the following field:

			<field
				name="article_index_text"
				type="text"
				label="PLG_CONTENT_PAGEBREAK_SITE_ARTICLEINDEXTEXT"
				useglobal="plg_content_pagebreak"
			/>

in plugin content page break add some text to field "Custom Article Index Heading", this will be your global value.

In the backend open an article for editing, open tab "Images and Links", in set "Intro Image" you should now see field "Image Class" and field (untranslated) "PLG_CONTENT_PAGEBREAK_SITE_ARTICLEINDEXTEXT" having "Use Global (....)" as value.
changing the useglobal to "true" in both fields, will still show the same value for the Intro Image (as it uses the fallback to component com_content), but empty for field "article_index_text" as that fallsback to the com_content component which doesn't have this field.

Try to fill in (bogus) values in the useglobal for these fields, these should then fallback to the component values

Actual result BEFORE applying this Pull Request

The text field would show empty

Expected result AFTER applying this Pull Request

The textfield will show 'Use Global (abc)' where abc is the value of the field in the plugin configuration
