[SOLVED] unset()

[The Little Guy]

Why does this not work?

 

unset($_POST['submit']);

 

I have this:

if(isset($_POST['submit'])){
   // Do some code
   unset($_POST['submit']);
}

 

and it always goes into that if when the page is refreshed... I don't want it to.

What are you trying to do? When testing to see if $_POST['submit'] is set, it doesn't need to be unset after the button is pressed.

I am submitting a registration form... but... I think I have a better Idea, I think I could just change the value of submit, and match against the value

Still, the question remains: why are you testing against submit?  Is it the actual form submission button?  Or have you named another form input 'submit'?  If it's the former, I can't think of a reason why you'd need to unset it.

I am curious now, are you going to have multiple submit buttons with different values?

If so:

<?php
//The test for submit
if(isset($_POST['submit'])) {
    $command = trim($_POST['submit']);

     if ($command == "Submit"){
        //Do something
     }
     if ($command == "Cancel"){
        //Do something else
     }
     if ($command == "Edit"){
        //Do something else
     }
}
//This will allow you to "see" which button was pressed.
?>

In addition to blackcell's code, attempt using switch() before you create a plethora of messy if statements. if statements still run even if one of the if's conditions are matched.

Yea, sorry about that, that was a snippet of one of my first programs.
