Occasionally I want to only display something based on the number of categories that is assigned to a particular entry. I wrote a small plugin to help me grab that number and use it in conditional statements. An example of use would be displaying a specific word like "category" versus "categories" in the sentence "This entry was filed in X category/categories." You could also choose to display content based on this number. A few examples of use are included in the documentation.
Currently it only returns the number of categories. If you have any additional suggestion for how this might be used or parameters you might get use from, let me know.
Looks like no one has left any words of wisdom yet...
