target first teaser in taxonomy/term page

ok, quick question, my brain is dead right now...
how might I target the first teaser in a teaser list, in order to style it differently?
I am using views - taxonomy_term view
Since it's a view you can
Since it's a view you can theme it, in this case you keep track if it the first node and add a flag to $node after node_load and before node_view, like this (the code would be added to your themes template.php file, if your viewed is named something other than 'taxonomy_term' replace taxonomy_term in the function name with your views name.
function phptemplate_views_view_nodes_taxonomy_term($view, $nodes, $type, $teasers = false, $links = true) {$first = TRUE;
foreach ($nodes as $n) {
$node = node_load($n->nid);
$node->first_in_list = $first;
$output .= node_view($node, $teasers, false, $links);
$first = FALSE;
}
return $output;
}
Now in your node.tpl.php file you could use $node->first_in_list to add a class to your outer div.
Hey, thanks nevets, that
Hey, thanks nevets, that should help me out a lot, very much appreciated.
For anyone who does not
For anyone who does not fully follow what nevets is saying, here is what I ended up using in my node.tpl.php file - this is the outer div code...
<div class="node" id="<?php if ($node->first_in_list) : print "node-first"; endif; ?>">Its safe to use an id rather than a class since there is only one of them.
I have a update to this
I have a update to this question that has been put to me...
How might we pull a single field from the first node (from the taxonomy term teaser list) and print it elsewhere, specifically in the header as a meta tag (desc).
These are CCK types with a "field_teaser", and its important to 1) not pull the title or links etc, just the field_teaser, and 2) that's its plain text with no markup at all and 3) able to print it in the header (which ever way).
We're using a unique template for taxonomy pages (page-taxonomy.tpl.php).
One possible approach
Since the page template file where you print the header does not "know" about either the list or the first node in the list I would resort to a global, starting with something like this in template.php (modified version of theme function from above)
global $first_node_teaser;function phptemplate_views_view_nodes_taxonomy_term($view, $nodes, $type, $teasers = false, $links = true) {
global $first_node_teaser;
$first = TRUE;
foreach ($nodes as $n) {
$node = node_load($n->nid);
if ( $first ) {
// You will want to strip any html
$first_node_teaser = check_plain($node->field_teaser[0]['value']);
}
$node->first_in_list = $first;
$output .= node_view($node, $teasers, false, $links);
$first = FALSE;
}
return $output;
}
Then in page-taxonomy.tpl.php you can declare and print $first_node_teaser.
Could you clarify a bit
Could you clarify a bit about what's going on here, perhaps if I can understand this a bit more I can get it to work.
Why is the variable $first_node_teaser declared as global in both the global and local scope?
How do you mean "declare and print $first_node_teaser" in page-taxonomy - isn't $first_node_teaser already declared i.e.
$first_node_teaser = check_plain($node->field_teaser[0]['value']);
Sorry, just trying to understand how this works and I am not entirely sure how to declare and print the variable in the page tpl.
You need to declare the
You need to declare the variable at global scope (the first one) and in ever function you reference it.
In the page tpl you would want something like
<?phpglobal $first_node_teaser;
print $first_node_teaser;
?>
You need to declare it global because it is not in the same scope as template.php.
Ok, I fully understand this
Ok, I fully understand this now, very good - I had to make a few small changes such as...
// added strip_tags to get rid of link code etc, check plain wasn't handling that and it all converted to html entities
$first_node_teaser = check_plain(strip_tags($node->field_teaser['0']['value']));
wrote a small function to convert remaining entities to normal characters, probably not necessary, but some were malformed for some reason so its just a function to strip out or convert any crap that remains, eg...
<?php
global $first_node_teaser;
print $first_node_teaser = replace_html_entities($first_node_teaser);
?>
