Drupal6: How to handle node links in user profile attributes?

Question

One of the fields in my user profiles is a list of nodes. (This list is generated automatically, based on other data on the site.) Currently, it displays like this:

Nodes

nid1, nid2, nid3

I want it to look like this:

Nodes

$nid1->title, $nid2->title, $nid3->title

where each title is a link to its node. What is the best way to do this? I tried filling the field with links generated by l(), but the html gets filtered out.

Also, when using l(), is there a way to say: create a link to the node with $nid, no matter where it happens to be located at runtime?

Answer 1

Concerning the first question:

The field values of a profile list are run through ´check_plain() in profile_view_field()`, so you can only get markup in there after they got loaded, which leaves you with at least two options, depending on where you want to alter the output:

1. Implement hook_user() and, on the 'view' operation, modify the field values in the $account->content array (Make sure that your modules weight is below that of the profile module or the values will not be in there yet).

2. Add your own preprocess functions for all templates where the fields are used and make your adjustments there. On first sight, these should be the following, but the list might be incomplete:

   1. yourModule_preprocess_profile_block() (profile module)
   2. yourModule_preprocess_profile_listing() (profile module)
   3. yourModule_preprocess_user_profile_item() (user module)

As for the second question:

Also, when using l(), is there a way to say: create a link to the node with $nid, no matter where it happens to be located at runtime?

I do not understand what you mean by "no matter where it happens to be located at runtime". Anything that is not covered by the following?

l('SomeTitle', 'node/' . $nid)
