I made a addentrymenu.php and connected into a certain mysql database(using a form and mysqlconnect)... I want to make user/s and password/s on that menu so that only authorized users can accessed my program.... because I tried to make a password menu using the if then else and inserting the addentrymenu.php on it.... it functioned but .... if ever I pressed the back on the browser address bar.... it accessed the the addentrymenu.php connecting to mysql database... The question is " where do i will put inside the addentrymenu.php the user and password so that when it will not connect using the back of the browser whenever it was logout. and when it will not affect the encoding returing aways to log on password upon refresh while encoding. When logout a tottally disconnected to mysql database. Can you give a layout or sample syntax... Thanks

your question is very confusing, but basically you should have a register page and a login page, not both on the same page.

for register:
1. they type in their username/password into the form and submit.
2. you check the $_POST array if the submit key is pressed for example if($_POST['submit'] == 'submit') //insert into the database

for login:
1. they type the username/password into the form
2. you check it against the database and then set a session or cookie to that says they are logged in.

if you still dont understand then there are many sites with sample code for simple login/registration, just google it.
