I am setting up a module to run on Magento 2.4.6-p5 multi-website instances.
The module requires that a dropdown category attribute be setup with a default value and n other options (1 initially).
I have this working as is but my question is on the XML and PHP class constants. I know I can use the class constants within the XML element node values and this is what I am doing for example in the field->argument->item[name="config"]->item[name="default"] here:
<field name="meps_scale"> <argument name="data" xsi:type="array"> <item name="options" xsi:type="object">MyVendor\MyModule\Model\Category\Attribute\Source\MepsScale</item> <item name="config" xsi:type="array"> <item name="dataType" xsi:type="string">string</item> <item name="formElement" xsi:type="string">select</item> <item name="default" xsi:type="string">MyVendor\MyModule\Helper\Data::DEFAULT_MEPS_SCALE_VALUE</item> </item> </argument> </field> ... My question is, can I use a class constant within a node attribute? And if so, how?
The use case being that I would like to replace the field name:
<field name="meps_scale"> with the PHP class constant of the attribute ID. Such as this pseudo code:
<field name="MyVendor\MyModule\Helper\Data::MEPS_SCALE_ATTR_ID"> I have looked at some of the Magento core module category_form.xml files but it seems they use literal values in the majority of modules.
