If this has been answered, I couldn't find it. On one specific field, I want to, basically, run a str_replace() to change an ampersand into the word 'and' upon submission. I don't want validation to report an error, I just want to handle it afterwards since the fields populate a GET URL.
I know I can likely dive into the code and create some sort of conditional function, but I wanted to see if there was a hook/filter that would do this more efficiently. Thanks!
