Template:GetCategory2

The template takes one string parameter, the page name of a crop/product. It determines whether this page is assigned to the higher category "Grasses/turf/rangeland" or the category "Mushrooms". If yes, it returns one of these category names. For determining the category of a pest, disease, weed, or beneficial/antagonist, see Template:GetCategory.

The template uses the following procedure:

1. It checks for higher categories of the page name using "{{#ask:[[<page name>]]|?Category=|link=none|format=list}}". This will only return a category if <page name> is a normal page and not a category itself. The result may be several categories, separated by commas.
2. It searches the return value for the string "Grasses/turf/rangeland" and if not found also for the string "Mushrooms".
3. The value may be blank, if none of the above 2 categories is found.

The template has the following structure:

1. Define the variable "Category" which will be either empty or
   contain a string of one or more higher categories..
{{#vardefine:Category|{{#ask:[[{{{1}}}]]|?Category=|link=none|format=list}} }}

2. Define the variable "Result" which is blank initially.
{{#vardefine:Result|}}

3. If a category is found....
{{#if:{{#var:Category}}|

   3a. define the variable "Position" which is used to determine if the string
       "Grasses/turf/rangeland" or the string "Mushrooms" is present in the variable "Category"
   {{#vardefine:Position|
      {{#pos:{{#var:Category}}|Grasses/turf/rangeland}}
   }}

   3b. analyze the variable "Result"
   {{#if:{{#var:Position}}|
      (the string "Grasses/turf/rangeland" is found, redefine the variable "Result")
      {{#vardefine:Result|Grasses/turf/rangeland}}
      | (the string "Grasses/turf/rangeland" was not found, search for "Mushrooms"...
         {{#vardefine:Position|{{#pos:{{#var:Category}}|Mushrooms}} }}
         If the string "Mushrooms" is found, redefine the variable "Result"
         {{#if:{{#var:Position}}|
            {{#vardefine:Result|Mushrooms}}
          }}
   }} (end of "{{#if:{{#var:Position}} ...")

}} (end of "{{#if:{{#var:Category}} ...")

4. return the variable "Result"
{{#var:Result}}
