I want to make a submit form that validates first through a .txt file then if validation is OK then I will send it.. for example I have a Submit form, and I will type on the form a number 50, then i have a number 50 on my .txt file and then, before i will submit the form i will click first the validate button to check if 50 exist on .txt file, if it exist, I will now send it..
Could you give me some sample codes? I really want to make one of this... Thanks in advance..
