[dokan_test] : A simple test shortcode that returns the string "SHORTCODE OK" to confirm that the snippet is running correctly.

[dokan_store_name] : Displays the name of a vendor's store. It can be used with an optional id attribute to specify a user ID.

[dokan_store_address] : Displays the address of a vendor. It automatically finds the vendor from the context of a product page or a vendor page, or you can provide a user ID with the id attribute.

[dokan_store_description] : Displays the vendor's biography or store description. Like the address shortcode, it can automatically detect the vendor from the page context or use a provided id.

[dokan_store_logo] : Displays the vendor's store logo. You can specify a user ID with the id attribute, and also provide custom class and alt attributes for the image.

[dokan_store_banner] : Displays the vendor's store banner image. It works similarly to the logo shortcode, accepting an optional id and custom class and alt attributes.

[dokan_store_link] : Generates a link to the vendor's store page. It accepts an optional id to specify the vendor and a label to set the link's text.

[vendor_name_link] : Designed for use within a product loop, this shortcode displays the vendor's name as a hyperlink to their store page. It automatically gets the vendor information from the current product's context.

[vendor_badge] : Also for use in a product loop, this shortcode creates an HTML element that displays both the vendor's logo and their name, with a link to their store page.
