[SOLVED] Values not passing

[dtyson2000]

Evening all...

 

Quick question:

 

I have what is probably a very simple script that compares a user's input with a set value to return a right or wrong answer. I have two functions, one to provide the initial value (not seen by user) and a field for user input. The second function compares the user's input with the initial value. The variables from the first function don't seem to be passing to the compare function. Here's an example of the code I'm dealing with:

function get_value() {
$initialval = "foobar";
...
<input type="textbox" name="user_value">
<input type="submit" name="submit">
}

function compare() {
if ($user_value == $initialval) {
	echo "right";
	}
	else {
	echo "wrong";
	}
}

$initialval = $_POST['initialval'];
$user_value = $_POST['user_value'];

if ($submit) {
compare();
}
else {
get_values();
}

 

It's probably something totally simple but I'm just not seeing it. Sorry if this is a little vague. I can clarify if there is a need for more.

 

Thanks, in advance!

I would suggest reading up on Variables Scope

 

And make sure your form POST as the method and that isntead of $submit you use

 

if (isset($_POST['submit'])) {

 

isset to see what that does.

 

EDIT:

Dang it Dan. Well I have a bit more info so still posting

Excellent. Thank you for pointing me in the right direction. I've got some reading to do now.

 

It's time I get this right rather than sort of fumbling through these things by just moving things around until they work.

 

Thanks, again!
