WampServer

PHP version 7.0.0
php MyAdmin Version: 4.7.0

I have two issues:



1. When I submit a form using $_GET, the data base works fine, but creates multiple rows with the same information

2. When I use $_POST, I get the message "Notice: Undefined variable: username in C:\wamp\www\NeptuneLogin\connection3.php on line 36

The only changes I am doing to the program is substituting $_POST for $_GET.

Thank you,
.

Hi

This sounds very much like a coding issue and nothing to do with WAMPServer itself.

We do not suppost the code you write in PHP, only the environment.

Please remember that PHP7 is very different to previous versions of PHP and therefore you should look at the Migration Notes

Also it is impossible to to debug code without being able to see it.
