Require a specific custom field value?

See General Options -> Registration/Profile Fields & Options then select Add New Field

Thanks for your reply! I know how to Add New Field, I’m just not sure how to make that newly added field require a specific value, like a registration code. I’d like to require the person registering to input the “correct value”. If the value does not equal the required and specific value I set, I want the registration not to process. This way I can allow free registration, but only to people who have the correct registration code.

Unless you want everyone to use the exact same code, you can use the Expected Format option to set what the code should look like when you Add New Field.

That’s great. I did anticipate using Expected Format. Thanks for confirming that. I assume if it’s set to exactly 10 alphanumeric, any combination of 10 alphanumerics can satisfy the field requirement? To be more specific, YES, I’d like to provide the exact registration code and have everyone use the exact same code. Without entering the exact code, I’d like the registration not to process…..or maybe, process and only allow Level 0 access if the exact code is not entered in the field, and maybe assign Level 1 access if the exact code is entered. Is there a conditional formatting I can use for this, or something I can enter in the Other Attribute field to make that New Field value = one specified value?

Thank you!

Hmm, I can’t give you the exact answer, but I suspect what you need to do is (a) identify the field, as explained here, and then (b) create an mu-plugin that requires that this field has a specific value. The basics for this are set out here.

If you can’t do this yourself, you could pay a developer to do it for you. You could ask krumch, for example. He’s regularly on these forums.
