Php javascript form submission passess field values on address bar

Good Morning Guys,
I am actually stocked here, I have a form developed in PHP with HTML script. The same form, on submit, values are validated before it proceeds to the SQL Database.

The issue now is that, when I submit the form, the fields value get displayed in the address bar after passing the validation test. I know there is a problem with my script, but how to figure it out, I don’t know. This is a common problem, I will appreciate if I can get assisted.

Regards
Michael

Hi,
is it possible that your form submit is not set to post:

but if you copy/paste the code we can give a look.
