<?php
$tip_poddonov = $hook->getValue('tip_poddonov');
$maxweight = $hook->getValue('maxweight');
$alldata = array ($tip_poddonov,$maxweight);
$string = print_r($alldata, true);
$modx->setPlaceholder('all', $string);
return true;

Array ( [0] => Array ( [0] => EUR, 800x1200x150 [1] => US, 800x1000x170 ) [1] => Array ( [0] => 1200 [1] => 1300 ) )

<?php
$allFormFields = $hook->getValues();
return true;

Вот пример для article, для других полей нужно только менять поле в запросе $update и $id_tv.

[[!pdoMenu?
                &context=`[[*context_key]]`
                &select=`id,pagetitle,parent`
            	&parents=`0`
            	&level=`2`
            	&templates=`16,13,18,19`
            	&tplOuter=`@INLINE [[+wrapper]]`
            	&tpl=`@INLINE <li><a href="[[+link]]">[[+menutitle]]</a><span></span>[[+wrapper]]</li>`
            	&tplInner=`@INLINE <ul id="submenu">[[+wrapper]]</ul>`
            	&tplInnerRow=`@INLINE <li><a href="[[+link]]">[[+pagetitle]]</a></li>`
            ]]
