I am trying to build a form in WordPress and taking advantage of all its built-in functions but I am hard pressed to find any functions that do form validation. I figure those kinds of functions have to exist in WordPress but I couldn’t find any because its documentation is sparse and spread out in some respects. Would anyone have any useful links to documentation and tutorials by any chance?
Does anyone know if WordPress has builtin PHP validation functions?
There are 1001 plugins that support contact form validation if that’s what your after:
WordPress Plugins Search
I don’t believe the WordPress code base has any exposed validation functions though. What are you trying to validate? Addresses/emails?
