multiple select extract

leatherback

Hi All,

I try to extract data from a multiple select form element.
How do I do this?

On the form I have a mulitple select (empty, here for illustration alone. On the page filled, of course):

Then in the target page I have:

     for ( $i = 0; $i < count($activiteit); $i++)
     {
     echo $activiteit[$i];
     }

But this always gives me nothing, no matter what the input was!

Please? Any ideas!?
J.

Hi Leatherback,

I tried playing around with this and came to the conclusion that PHP does not handle multiple selects like javascript does. It looks like php only holds the last selected value in the list in the variable so why you are not seeing any output is because the for next loop is not executing. I tried echoing the count of the so called array that should be generated when the select is evaluated and no matter how many selections I made (1, 2 or 3), it always came back as a count of 1... meaning that php is not turning the selction values into an array. Not sure why...will keep looking....

Hi,

I solved it.
Instead of:

I now use:

which creates an array (activiteit[], an therefore works perfectly. I am not sure why it does not create one automatically though. Anyway.. I then extract the results:

           for ( $i = 0; $i < count($activiteit); $i++)
            {
            SOMETHING... $activiteit[$i] SOMETHING ELSE;
            }
