A fairly simple snippet questions

It seems to me that the only thing left is that when $input is set from the passed parameter, it’s the wrong variable type.

You might try casting it:

return $xmlData->SONGHISTORY->SONG[(int)$input]->TITLE;

I changed that and it looks like it works now! I guess that was the problem all along, This is good to know for future reference

I’m not sure where your $input value comes from, but if it’s from POST or GET, those are always passed as strings.

$input is passed in from the snippet call (not sure if thats POST or GET)

Neither, but all snippet parameters are treated as string values when passed via a snippet tag (i.e. [[ ]] or [! !]), as well. When calling a snippet using $modx->runSnippet() however, the values will reflect the actual type that is passed in via the second parameter (an array of snippet parameters).

Very nice. Can I assume that it’s impossible for a miscreant to cause a snippet to execute or pass it fake parameters using POST or GET?

This is where your register_globals setting comes in... although I believe that the variable scope inside snippets is limited anyway.

This snippet thing is really starting to bug me.

Whenever I call the snippet twice in a chunk (with different array locations in the parameter), I get the following;


How do I go about actually having the main function run once and display twice on a page?
