getCollectionGraph() question

What am I doing wrong here:



The same code works with users or using getObjectGraph() but this chokes:
.

Your getCollectionGraph() is perfectly ok and working.
Your problem is actually with the var_dump:
Modx IS parsing the returned pages and gives you back this "cannot redeclare quote_meta()" - you shouldn’t care about this. just go on with your real parsing.

for testing: replace your var_dump with print_r and the "problem" will disappear.
oh, and add an ’if !empty’ to the second case:
if (!empty($resource->Children)) print_r($resource->Children->toArray());

Duh. Docs with no children.

Still, not quite right, though.

On the first document that has children, it fails, telling me that $resource->Children is not an object.

If I do print_r($resource->Children), (rather than Children->toArray()) I get a monstrous dump of everything from soup to nuts, but no errors.

Duh again. $resource->Children isn’t an object (unlike $user->Profile). It’s an array of objects.

Yes. getMany vs. getOne
In your case you use the xGraph methods, so you’ll have to know what you expect.
although it’s the same, sometimes it’s better to use the getMany/getOne and not the xGraph methods - then you know for sure what to expect. You can also take a look at \core\model\schema\modx.mysql.schema.xml to see how the relationships are defined.

Sure.. depanding on your php settings you can even just get an endlessly long loading page...
just use the ->toArray() or a ->get() specific field - anyway it’s temporary, you do this print_r only for tracing/debugging.
