above is my check box, normally name=”book[]” can someone explain what
the purpose of the [] is?
This is allowing the checked values to be returned as an array when getting the results, if you have more than one value checked.
Besides that, I can’t tell what you’re trying to do in order to be able to answer the other questions. Especially the last part. It appears like you’re asking someone to write the code for you, for process_bulk_action()? There’s not enough specific question to answer.
