Snippet - TV - Chunk interaction

I would like to know how snippets, tvs and chunks play together in modx.
Up to now I think I figured out the following:
1. You can pass parameters for a snippet-call using a chunk in the template-line invoking the snippet
2. You cannot pass parameters for a snippet-call using the value of a tv-variable

So: in which sequence are the different "content-types" (just to give it a name) computed?

My guess: TVs come in after rendering - that’s why they could be so nicely integrated in "post-editing" (I mean QuickEdit), the drawback, however, is that you cannot "quickedit" the params of a snippet.

Varying a well-known truism: Asking the developer can save hours of reading source-code

I’m french so excuse me  If I misunderstood your questions.

But For the point 2/ I disagree
You can pass TV value for a snippet call in your template.

You can edit Your TV in front End using FCKeditor, If you wish to see a specific button in your front end call your TV [*#myTV*] in your html code.

:-)

Hmm, I guess that’s not exactly what I meant:
Maybe that I can call a snippet using a TV (if my assumptions were correct, this would not be possible - in so far you’re right!), but I have experienced that I cannot change the value of an already called snippet using a TV.
My example: I called the Dropmenu-Snippet (in the template code, providing a TV-variable) and wanted to set its starting document (startdoc) individually for the pages, but the value passed to the tv (a document-id) had no effect. The TV value itself was stored in the page-record, but the behaviour of the snippet (the appearance of the menu) wasn’t affected though.

After having tested , you’re right !
If you set by hand the startDoc and call Twice( with two different values for startDoc) in the same template DropMenu, you obtain the expected result => two different menus

If you call a TV to set one of the startDoc, this value is overwritten by the first call.
I’ve tried with phMode=true and [+placeHolder+] but the result is the same.

:-)

I can’t say much right now but let’s say new things will come up in the future that will allow to do exactly what you need
