Restrict articles to certain content types

I second that. The article module should definitely have an option for showing only a subset of the available node types.

For exampl,e in a typical case, the "page" node type is used for the static site content, the "story" node type for articles and maybe (using the weblink or janode module) a "link" node to create a directory of useful links.

Now you wouldn't want to show the static site structure when the user is browsing for articles. Neither would you want to show all the site's articles in your link directory.

I helped myself with a little modification:

1) Adjust the node counts displayed on the taxonomy tree

Replace
$cur->count = module_invoke('taxonomy', 'term_count_nodes', ($cur->tid));
by
$cur->count = module_invoke('taxonomy', 'term_count_nodes', ($cur->tid), ('story'));

2) Modify the select_nodes function:

Replace
function articles_select_nodes($tids = array(), $operator = 'or', $depth = 0, $pager = TRUE, $count = 0) {
by
function articles_select_nodes($tids = array(), $operator = 'or', $depth = 0, $pager = TRUE, $count = 0, $type = 0) {

3) Inside that function, replace

$sql = 'SELECT DISTINCT n.nid, n.title, n.sticky, n.created FROM {node} n INNER JOIN {term_node} tn ON n.nid = tn.nid WHERE tn.tid IN ('. $str_tids .') AND n.status = 1 ORDER BY n.sticky DESC, n.created DESC';
$sql_count = 'SELECT COUNT(n.nid) FROM {node} n INNER JOIN {term_node} tn ON n.nid = tn.nid WHERE tn.tid IN ('. $str_tids .') AND n.status = 1';
by
if(is_numeric($type)) {
$sql = 'SELECT DISTINCT n.nid, n.title, n.sticky, n.created FROM {node} n INNER JOIN {term_node} tn ON n.nid = tn.nid WHERE tn.tid IN ('. $str_tids .') AND n.status = 1 ORDER BY n.sticky DESC, n.created DESC';
$sql_count = 'SELECT COUNT(n.nid) FROM {node} n INNER JOIN {term_node} tn ON n.nid = tn.nid WHERE tn.tid IN ('. $str_tids .') AND n.status = 1';
} else {
$sql = 'SELECT DISTINCT n.nid, n.title, n.sticky, n.created FROM {node} n INNER JOIN {term_node} tn ON n.nid = tn.nid WHERE tn.tid IN ('. $str_tids .') AND n.status = 1 AND n.type = \'' . $type . '\' ORDER BY n.sticky DESC, n.created DESC';
$sql_count = 'SELECT COUNT(n.nid) FROM {node} n INNER JOIN {term_node} tn ON n.nid = tn.nid WHERE tn.tid IN ('. $str_tids .') AND n.status = 1 AND n.type = \'' . $type . '\'';
}

4) Still in this function, replace

$wheres .= ' AND tn'. $index .'.tid IN ('. implode(',', $tids) .')';
by
if(is_numeric($type))
$wheres .= ' AND tn'. $index .'.tid IN ('. implode(',', $tids) .')';
else
$wheres .= ' n.type = \'$type\' AND tn'. $index .'.tid IN ('. implode(',', $tids) .')';

5) Finally, in articles_page(), replace

print theme('page', $body . module_invoke('taxonomy', 'render_nodes', module_invoke('taxonomy', 'select_nodes', $terms)));
by
print theme('page', $body . module_invoke('taxonomy', 'render_nodes', articles_select_nodes($terms, 'or', 0, TRUE, 0, 'article')));

Closing this. Please reopen if still relevant.
