In Freeform, How do I specify return page from channel field in composer tag?

Question

I'm using the Freeform composer tag to pull a form into an EE template, but I can't work out how to set the return value to whatever page the users puts into the Freeform channel field. It works fine if I specify a specific page in the tag.

This is my tag as it works (form_select_form is my custom field):

{exp:freeform:composer form_id="{form_select_form:form_id}" form_name="{form_select_form:form_name}" return="/message/thanks"}

What I'd like is the equivalent of:

{exp:freeform:composer form_id="{form_select_form:form_id}" form_name="{form_select_form:form_name}" return="{form_select_form:user_specified_return_page"}

Any ideas?

Currently, you can't. Also "{form_select_form:form_name}" isn't a valid variable. Where you have:

form_id="{form_select_form:form_id}" 

Which is valid, this is doing the work of form_name="" already, thus you are seeing no error. So even if it did work, it would be redundant.

I've added a feature request for a better way to accomplish this scenario, but one thing you could try is editing:

./system/expressionengine/third_party/freeform/ft.freeform.php

around line 232 there is:

ee()->TMPL->tagdata     = '';

Which is a hack to allow the module's composer setup to work as params passed into the channel entries tag for the Freeform field are passed as tagparams to TMPL.

Try editing line 232 to look like:

ee()->TMPL->tagdata     = $tagdata;

Then around line 32, set:

public $has_array_data  = FALSE;

to:

public $has_array_data  = TRUE;

This should pass any incoming tagdata towards composer let you put your composer data between field variable pairs like so:

{form_select_form}
    //composer tags
{/form_select_form}

I will add this to feature requests and see what we can do sometime in the future about making this part of Freeform.
