I have a wordpress function in functions.php which gets parameters from a form I made and gets parameters like IP addresses and UTM tags (from the URL) and sends them to me by email.
I want to get all these parameters I send and store them in a new table on my WP database.
How can I do such thing?
I researched it and found a lot of plugins that can do that for me (Which I really don't want to use external plugins). and I still want to keep wordpress security and not use a "flat" code of my own.
How do I plan this? Is this even possible?
