I am having a bit of trouble. It does not seem to be a big deal, but I have created a page that the user can edit a MySQL database. Once they click submit it should process the php within the if statement and echo 1 record updated. The problem is that it does not wait to echo the statement. It just seems to ignore the way I wrote my if and display the whole page. Can anyone see where I went wrong.

1) Should not have a semicolon after it.
2)
$_POST['submit']is not set. You have to set a name on your submit button and give it a value. Just setting the type to ‘submit’ does not return a value for$_POST['submit']in PHP.
