add questions with wp_insert_post func.

Yes you can! HD Quiz uses a custom post type and taxonomy, so totally possible.

However, please note that HD Quiz is ~5 years old now, and I named things… well, stupidly back in the day.

HD Quiz is currently going through a large rewrite in order to modernize the way data is saved and retrieved as well as making just about every facet of HD Quiz “pluggable”.

IF you can wait ~a week, the next version is a big revamp and will also include a basic CSV importer.

If you can’t then the best place to take a look at is /includes/functions.php to take a look at the variables.

here is a handy chart to help know what the question vars are currently, and the expected data type/values.

text = sanitize_text_field
content = wp_kses_post
integer = integer
checkbox = if enabled, value should be set to "yes"

I’ll be pushing the next version out tomorrow 🙂

Once released, you can take a look at ./includes/tools/data_upgrade.php to see how the data is saved. Basically, it’s an array with each field having a key for type and value. Type is the type of input (text, textarea, checkbox, radio, select, integer, float, editor).
