Create a TV that can be dynamically populated by a group of resources.

Hi, I need to create a TV that can be dynamically populated by a group of resources, not sure on the best approach. Let me explain what needs to happen:

I'm developing a site that will have several dozen client testimonials, I want to create a group in the resource tree for these testimonials so that the client can add a new resource for each new testimonial. fine - easy enough. Where it gets tricky is that on each page I want to include a testimonial that the client can pick. i.e. they create a new page/resource and in the template variables section there is a pick list/drop down of all the available testimonials.

So I'm not sure what the best way to handle this is, ideally, create a snippet or chunk or something that uses getResources to retrieve the list of child resources for the testimonials tree & somehow populates that TV on the fly... ?

- any suggestions?

I've done something similar on an old Evo site but guess the principals are going to be the same. Basically had a recourse that contained a child resources, each of which where a sales contact. The client could add more as and when.

I created drop down tv and as the input values i had:



Parent being the resource ID that contained the sales contacts.

Does the client need to see the content of the resources, or would the pagetitle do?

One way would be to use @EVAL in the TV's Input Option Values field to run a custom snippet (with runSnippet() ) that would grab what you need from those resources and return it. The client could select one from a drop-down list or radio options.

no - the client only needs to see the resource title... I thought there was a way to reference output from a chunk in a TV?

Have a look at the resourcelist TV input type.

When in 2.1 it'll give you a bunch of options to fine tune it, in <2.1 I think you need to specify the ID of the parent resource in the input options field.

I shake my head every single time I see how easy stuff like this is in modx.
That works perfectly, all I had to do was setup the resourcelist TV point it at my parent resource and then in my template:



& the chunk



Thanks Mark...

Hehe, MODX does that

There's another related tutorial here that makes use of a snippet and @EVAL, though it is aimed at showing multiple resources (in your case, testimonials): http://rtfm.modx.com/display/revolution20/Creating+a+multi-select+box+for+related+pages+in+your+template

Thanks Mark... heh-heh... "client proof" I love it...

I totally forgot about the resource list TV type (although it's in my book).
