Yup, I'm hopeless. Maybe someone knows a good PHP tutorial for me . Can someone help me(again )
I would recommend using the POST method on your form, and then you are able to reference them like this: $POST["fieldname"] where fieldname is the name of your formfield. If you choose to use GET, you reference them like this: $GET["fieldname"]
so I would do this:
$whatever = $_POST("text_input");
Would I have this in the HTML or in the form target file?
The form target file, and they need to be brackets  rather than parenthesis ()
oops... OK thanks.
