How to check if a resource has been deleted by id in a chunk?

Question

MODX

In the tv parameter, there is a list of id that are added manually. But some resources are removed and thus the error is displayed. How to write a condition: does a resource with this id exist (or is it published)

Here is the migx_recommended_service chunk:

<div class="col-md-6 mb-base col-xl-3" style="">
    <a class="brand" href="">
        <span class="brandtext"></span>
        <img class="img-fluid" src="" alt="">
</a>
</div>

Answer 1

You can try this way.
First , using the getImageList snippet , we create a comma-separated list of resource ids:

getImageList parameter instruction .
And then we use the pdoResources snippet for output , which will filter out unpublished and deleted ones.

Chunk recommended_service :

<div class="col-md-6 mb-base col-xl-3" style="">
    <a class="brand" href="">
        <span class="brandtext"></span>
        <img class="img-fluid" src="" alt="">
    </a>
</div>

But, if this was my project, then I would first try to write my own snippet, which would first check TV migx_recommended_brands: I would delete the id of non-existent resources there, filter out unpublished ones and draw a conclusion on my own.

Answer 2

add &where=`{"deleted:=":"0"}` to the snippet call

I don't remember the default syntax, but something like this:
