How to get migx data array?

Question

MODX

How do I get an array of data from migx so that I can use it in a snippet. I need to make conditions there and it is very easy to work on php. But I don’t understand how to get an array, I understand that I need to give the correct query to the database, but I don’t know how. Is there anyone knows?

Answer 1

If we are talking about data that is saved in TV with the migx input field, then the output is JSON.
That is, the work will be something like this:

$doc = $modx->getObject('modResource', 15); // Получили объект ресурса с ID, например, 15
$migx_value =  json_decode($doc->getTVValue('your_tv'), true); // получили значение TV и перекодировали из JSON в массив

And then went any work.
In templates, it is convenient to work with such values ​​through Fenom:

{set $val = $_modx->resource.my_tv | json_decode : true}
// Любые операции, например, перебор
{foreach $val as $item}
<p>{$item.title}</p>
{/foreach}
