====== multiLevelData() ======

''mixed **multiLevelData**()''

In the subordinate questionnaire, the function ''multiLevelData()'' returns the data that was specified as the second parameter in ''[[:en:create:functions:multileveldown]]''.

For details on the multi-level function, see [[:en:create:multilevel#real_multi-level_design|Multi-Level Design]].

===== Example =====

For example, the superordinate questionnaire can pass a serial number and a description:

<code php>
$i = loopIndex();
$num = $i + 1;
$desc = value(id('AB01', $num));
// Create an array with two elements for number and description
$data = array(
  'num' => $num,
  'desc' => $desc
);
// Call the subordinate questionnaire "sub01" and pass this data
multiLevelDown('sub01', $data);
</code>

In the subordinate questionnaire, this data can then be used:

<code php>
$data = multiLevelData();
html('<p>Number '.$data['num'].'</p>');
replace('%title%', $data['desc']);
