Do you want to enter the fields in the database on the side of the form?

form here is not to enter the fields in the database
A little unsure.

------to solve the idea----------------------
No, such as the database field is aid, submitted backstage after receiving data with $aid = $_post[' Areaid '], $data [' Aid ']= $aid; When you insert a database, the field corresponds to its value.
------to solve the idea----------------------
The name of the form is not necessarily consistent with the field name of the database, it is used only when the data is received;

If your data field is Xxx_areaid (whatever else you define), you can use the table sole name $_get[' Areaid ' when you fetch it;
