I want ‘Accounting,Legal,Business Other’ categories. So, I set up these names in ‘Form Fields'; and in ‘Manage Options’ ‘Directory Category IDs’ added ‘100,101,102’ (not sure what the connection is…)
Then, when I try to add a New Business and submit, I get a ‘Business Genre Required’ error.
The business directory categories are set from your WP categories page the same way you set up your normal WordPress categories. The business directory uses the categories you tell it to use, so you do not add the categories as form fields. You add your categories by going to Dashboard->Posts->Categories
Once you have added the categories you want for the business directory, you then tell the plugin the IDs of the categories to use. Please see http://businessdirectoryplugin.com/blog/2010/04/22/specifying-which-wordpress-categories-wp-business-directory-should-use/
The plugin comes with a field named “Business Genre” that is already setup to associate itself with the WP category. That means you don’t need to do anything except change the name from “Business Genre” to something else if you don’t like that name. You don’t need to and should not change anything else related to that field.
