How to check if the tv value of another resource is empty?

Question

MODX

The main page has a tv with an image that will be used on different pages and different templates. I was able to get the value of tv via . There is a chunk in which you need to check the value of the field and if it is not empty, then output html

<div>
    <img src="">
</div>

Is there a way to wrap this block in an if? Or does it need to be done differently in modx?

Answer 1
