Can a placeholder be a parameter in a snippet call?

I’ve written a snippet that puts the docID of the referring page into a placeholder named [+referingDocId+]. I want to use it as a parameter to the GetField snippet. But when I call GetField as follows...

[!GetField? &docid=`[+referingDocId+]` &field=`content` &parent=`0` !]

... I get no output.

Is this because: (a) placeholders can’t ever be parameters in snippet calls, (c) GetField can’t handle them, (c) I’ve got some garbage in my result (although it looks like a simple integer), (d) I’m using the wrong syntax, (d) other...?

(a) is the closest answer. In most cases, snippets are processed before placeholders by the current version of the document parser.

Best bet is to use $modx->runSnippet() from within your first snippet to get the desired output from the GetField snippet.

Hope that helps,
Garry

Thank you very much. I’ll try that.
