No error msg but it doesn't do anything

[demonicfoetus]

Hi ppl,
i have a HTML form, with a drop down menu. When a user selects a certain option i.e. 1a from drop down menu i.e. qone, the script then adds 1 to a respective variable. Now, the script is shown below, when i run it, no errors appear... but if i select "1a" the script doesn't detect it and so doesn't use the if and so the percentage it gives is still 0% not 10%.

Any ideas? Do i have the HTTP_POST incorrect? Or should i be using GET or wot? Plz! This is driving me crazy!

Thanks,

<?

if( $HTTP_POST_VARS["qone"] == "1a")
{
$ideal + $one;

}

if($HTTP_POST_VARS["qone"] == "1b")
{
$average + $one;
}

if( $HTTP_POST_VARS["qone"] == "1c")
{
$die + $one;
}

echo "<p>".($ideal 10)." % ideal for the future</p>";
echo "<p>".($average 10)." % just about survive</p>";
echo "<p>".($die * 10)." % likely to be executed</p>";
?>

Regarding POST or GET... check your form. If you have "METHOD=POST" then use POST. If you have NO method specified in your form, use GET.

I'm using POST but i changed to GET to see if it would work. But the weird thing is, if i look at the GET string after the URL contains qone=1a which is wot i want to to say, it shows i have selected option one. But the script doesn't detect this and so doesn't run complete the IF Statement. Very strange.

Any ideas? Sounds like a challenge to me

What is:

$ideal + $one;

?

Or the others for that matter. I just now noticed that. You are not assigning that value into any variable that you are echo'ing out.

Hi, $one is just '1' its just adding one
The others 'qthree' and so on. Are the names of the drop-down menus so should be automatically created when the form is used.

But u still hav no idea why its not detecting that a certain option is selected?

[frigidman]

I believe it IS detecting which one is selected. You are just not assigning the variable correctly is what I meant.

Use a "=":

if( $HTTP_POST_VARS["qone"] == "1a")
{ $ideal = $one; }

if($HTTP_POST_VARS["qone"] == "1b")
{ $average = $one; }

if( $HTTP_POST_VARS["qone"] == "1c")
{ $die = $one; }

$ideal + $one; does absolutely nothing for $ideal.

Why do you have a constant for 1 called $one???

That's 3 extra characters!!

If you are trying to add one to it, use:

$whatever++;

or

++$whatever;

The first one returns $whatever and increments $whatever, the second increments $whatever and returns the incremented value.
