Answered Can Modx create a new menu-index TV?

$tvs = $xpdo->getIterator('modTmplVars', array('tmplvarid' => 8));

function array_move(&$a, $oldpos, $newpos) {
    if ($oldpos==$newpos) {return;}
    array_splice($a,max($newpos,0),0,array_splice($a,max($oldpos,0),1));
}

switch($eventName) {
    case 'OnBeforeDocFormSave':
       $told = $resource->getTVValue('rank');
        break;
        
    case 'OnDocFormSave':
        $tnew = $resource->getTVValue('rank');
        break;
}

 $_REQUEST['rankold'] = $resource->getTVValue('rank');

 $modx->rankold = $resource->getTVValue('rank');

modTemplateVarContent

$tvs = $modx->getIterator('modTemplateVarResource', array('tmplvarid' => $tvid));

$tvId = ##;  // Change this to the ID of the top10 TV.
 
$c = $modx->newQuery('modTemplateVarResource');
$c->sortby('value', 'ASC');

foreach($tvrs as $tvr) {
   $tvr->set('value', $i);
   $tvr->save();
   $i++;
