Array not saving in data output

Question

Hi,
We are programming a fairly complex multi-day survey. We randomly show words paired with other stimuli and created some functions for this. However, currently we are unable to save any of the information in the data. I have created an internal variable and tried to use the putList() function, but the data entries for IV02 remain empty...

Here is an excerpt from the code:

// Create a schedule for the number of days
function createSchedule($numDays, $numOld, $numNew, &$specialItems, &$specialItemsSchedule, $valenceCondition, &$words) {
    $schedule = array();
    for ($i = 0; $i < $numDays; $i++) {
        $daySpecialItems = array();
        if (array_key_exists($i, $specialItemsSchedule)) {
            $daySpecialItems[] = &$specialItems[$specialItemsSchedule[$i]];
        }
        $schedule[] = createDay($numOld, $numNew, $daySpecialItems, $valenceCondition, $words);
      putList('IV02_01', $schedule);
    }
    return $schedule;
}

Answer 1

putList() is intended to save an array to multiple internal variables, so please place is below the }, and only name the question, not the variable itself, that is:

        $schedule[] = createDay($numOld, $numNew, $daySpecialItems, $valenceCondition, $words);
    }
    putList('IV02', $schedule);
    return $schedule;
}

You may also want to add a debug() to see, if $schedule works properly:

        $schedule[] = createDay($numOld, $numNew, $daySpecialItems, $valenceCondition, $words);
    }
    putList('IV02', $schedule);
    debug($schedule);
    return $schedule;
}

And most importantly, make sure not (!) to drag the IV02 question on the page. It that still does not work, please post the debug information from that page.
