Modx php & Template variable

Is there a way to do something like that in a snippet : <?php if ([[+idx]]==1) echo "0";<?

Thank you.

Solution

  • If you need to get the value of a template variable, you can use this

    $id = $modx->resource->get('id');//ID of current resource
$name = $modx->resource->get('pagetitle');//title of current resource
$val = $modx->resource->getTVValue('name_of_tv');//get tv value of current resource by name
$val = $modx->resource->getTVValue($tv_id);//get tv value of current resource by ID

    To get idx of migx tv you need something like this -

    <?php
$docid = $modx->resource->get('id'); // id of curent resource
$tvname = 'name_of_your_tv'; // change to yours
$tv = $modx->getObject('modTemplateVar', array('name' => $tvname));
$outputvalue = $tv->renderOutput($docid);
$items = $modx->fromJSON($outputvalue);
$idx = 0; // initialize idx
$output = array();
foreach ($items as $key => $item) {
    $idx++; // increase idx
    $output[] = print_r($item,1); // test output
}
$outputSeparator = "\n";
$o = implode($outputSeparator, $output); // implode output
return $o;
