false property not working

Archbob

Okay at the end of every if and else state I have this:

$submit='false'

The prevent the action from happening again when the page refreshes. Yet it doesn't work. What do I do?

When a page is refreshed the php script starts over from the beginning so when you set $submit to false, false is lost when it is refreshed. I think what would work is a session variable. Try changing all of your $submit to $_SESSION['submit'] I am also fairly new to PHP so if I'm wrong about this I'm sure the pros will correct me but I believe this will work.

As rpanning said, when you refresh a page, the variables that were set the last time you ran the script are no longer set. It starts from the very beginning. Because of this, you will have to specify your variables from either your URL or a session, as rpanning advised.

To refer to variables in the URL, use $GET['variable_name'] . To refer to variables in a session use $SESSION['variable_name'] .

If you want to use a session, as rpanning has said, you will have to have a session_start(); function at the top of your script as well as any other page that you wish to use the session variables. Also, a session will remain active, with the variables set, for an hour (iirc), or until the user closes their browser.

Take a look at http://www.php.net/manual/en/language.variables.php and http://www.php.net/manual/en/ref.session.php

It's kind of irrelevant, but it was pointed out to me recently and I thought it was an interesting thought...when you use $foo = "true"; You are not using a boolean value...it's just as string, as if it were $foo = "bar";. So, using $foo = false; (without quotes) is a proper bool.

I don't know if it makes any diifference, because I believe that doing if($foo == false) on a "false" string would still come up correct. I just thought I'd mention it. Yeah...

I think I have a way without using sessions on the if statement I'll just put:

print "<form action=selfpage.php method=post>";
print "<input type="hidden" name="submit" value='false'>";
</form>

that way no matter what the form will pass false onto the refresh.

That should work. Just make sure that the submit botton is not also named submit. Ex:
Don't use:

<form action="selfpage.php" method="post">
<input type="hidden" name="[COLOR=red]submit[/COLOR]" value="false">
<input type="submit" name="[COLOR=red]submit[/COLOR]" value="Submit">
</form>

Use:

<form action="selfpage.php" method="post">
<input type="hidden" name="[COLOR=green]submited[/COLOR]" value="false">
<input type="submit" name="[COLOR=green]submit[/COLOR]" value="Submit">
</form>
