  • I’m seeking to test for the existence of a category (by name) and if the category does not exist, I’d like to create it.

    I’m using the following code in my theme’s functions.php file…


    However, its returning an undefined function error. I suppose I need to include taxonomy.php in my functions.php?

  • I thought the wp_create_category is already checking if the category exists.

    yes wp_create_category will return the existing category id or false.

    Remember the passed category name must be an exact match.

    Download and Downloads would result in 2 categories.

    No need to add the compare, as get_cat_ID returns ‘0’ or the catagory id if found, and as 0 will be seen by the code as false you could use if not ! .


    If that fails let me know as I have a function that will work for this situation, I use in my themes to add default categories, as I wanted to be able to add the parent category by name as well so I created my own function as wp_create_category needs the parent ID and will not accept a name.
