}But my form/profile has additionally about 25 different text-inputs and some textareas, which I'd like to search at once. I don't understand how I can access all values of every field in my ext_user_data-table?
if (isset($_POST['submit-var']) && $_POST['submit-var'] == 'etaoinshrdlu') {
$fields['where'] = '{"vorname:LIKE":"%' . $pFirstName . '%","OR:nachname:LIKE":"%' . $pLastName . '%","OR:keywords:LIKE":"%' . $pKeyWords . '%","OR:keywords2:LIKE":"%' . $pKeyWords2 . '%"}';
$results = $modx->runSnippet('GetExtUsers', $fields);
