Solspace Facebook Login - Dynamic Return with {segment}

Question

Might be an odd scenario, but i'm looking to use Solspace's facebook Login with a dynamic return by using segments in the url.

Currenttly fbc:login throws an error when I use any {segment} tags in the parameters.

Here's how they say to use the module: {exp:fbc:login permissions="email|publish_stream|read_stream" return_when_logged_in="site/home" return_when_logged_out="site/home" return_to_register="site/register" return_on_failure="site/fail" } {/exp:fbc:login}

Here's what i'd like to do

{exp:fbc:login permissions="email|publish_stream|read_stream" return_when_logged_in="{segment_2}/{segment_2}" return_when_logged_out="s{segment_2}/{segment_2}" return_to_register="site/register" return_on_failure="site/fail" } {/exp:fbc:login}

Answer 1

Using this kind of conditional in a parameter won't work well:

return_when_logged_in="{if segment_2}/'{segment_2}'{if:elseif segment_3}'{segment_2}'/'{segment_3}'/{if:elseif segment_4}'{segment_2}'/'{segment_3}/'{segment_4}'{if:else}/{/if}"

First, you shouldn't need those single quotes, as this could cause more issues than less.

Also with the above, you're using an advanced conditional within an {exp:...} tag's parameter. This gets parsed after the {exp:...} tag, which likely is giving you the error. Always use simple conditionals when working with parameters. In this case you could simply try:

return_when_logged_in="/{segment_2}/{segment_3}/{segment_4}"

However, your return URL may have a number of slashes at the end, eg. http://mysite.com/template_group/template//.

A better solution is the following, all using simple conditionals:

return_when_logged_in="{if segment_2}/{segment_2}{/if}{if segment_3}/{segment_3}{/if}{if segment_4}/{segment_4}{/if}"

Notice how all conditionals are simple conditionals. These will parse before the {exp:...} tag.

This is general EE advice, by the way, so can come in handy with 1st- and 3rd-party tags.
