A few final questions about my project. I have a form with quite a few fields that are optional. If user doesn’t fill them in, the form still submits them and creates empty custom fields in the database.
To be clear, I’m not asking about the display issue – I’ve got that covered. What I’m hoping for is a way to stop the form from inserting the key/value pair when the value is empty. Is this possible?
Also a general question about form security. I’ve added some validation relevant to what I’m asking users for. But am not clear on what validation is built-in to FRM and/or to the WP processes you’re using. Does FRM do any checking, or is that up to each developer to do that?
I’m not an expert on validation and security, so I don’t know what to ask here. Basically I’m asking how safe FRM forms are for accepting user generated content. Thanks.
