Add button on custom data tab with contact?

[Erik Hommel]

Hi all,
a little help to get me on my way. I have added a custom data group, which show up as a tab on my contact summary. Fine! Now I want to add a button or link to the specific tab so I can jump to an external URL. I have tried to establish this with the civicrm_links hook, but that adds a link to the main summary page, and I can not yet get my head around the structure that is used to build up the tabs.
I thought I could use the civicrm_tabs hook, but that does not seem to do the required stuff either?
Can you give me a little push?

Managed to get there in the end, using the civicrm_tabs hook......!!! can I now applaud for myself

You could also have modified the template...

I know.....but I probably want to do much more once I understand the engine. So I thought I'll give it a try in this way. Once you show me stuff in Brussels I want to use it

And also....I have a hard time finding the right template

The usual trick: view source and search for ".tpl"

For an ajaxified bit, open firebug, you'll see what "page" it opens. You have the option to open it in a new tab, so you can do the view source.

Thanks Xavier, I was aware of the tpl-trick, but that did not help me in the case of the Contact Summary, and then getting to one of the tabs. I'll have a go with firebug!
