There are two textare boxes and one text input box in the form and it is being saved as post metadata using a _POST action.
What would you suggest I use to sanitize the data that is being saved? And, where would this sanitizing function go?
I found a plugin called The Content Injection but it's not being developed any more. Is there a plugin that adds code, text, ads, etc to each post that's already published? I'll be changing out the post top and/or bottom text every few days. I just need something that will allow me to add quick reminders.
