Drupal: how to make select list show taxonomy terms in hierarchy?
10,555
Solution 1
My solution: since I don't need much of Finder features, I came up with an alternative solution using just Views:
In the view listing all the nodes among which I'd like to search I added a filter
Region:
Filters > Taxonomy > Term (The taxonomy term ID) > "regions" vocabularyI exposed the filter, set it to dropdown and checked
Show hierarchy in dropdown
Then I exposed the form into a block
4 And enabled the block under admin/build/block
It works fine for me. :-)

You can do this really easily without a Drupal module if you're just theming:
$tree = taxonomy_get_tree($vid);
if ( $tree ) {
$content .= '<select class="your-class">';
$content .= '<option class="placeholder" value="">You Dropdown</option>';
foreach ($tree as $term) {
$path = taxonomy_term_path($term);
$content .= '<option value="/terms/' . strtolower(str_replace( " ", "-",$term->name)) . '">' . $term->name . '</option>';
}
$content .= '</select>';
}//end if ( $view )
return $content;
}

I have a block generated by Finder module (simple search mechanism). The block contains a form with select lists of various taxonomy dictionaries. Their order, however seems quite random (neither, alphabetical, nor chronological) and lists regions in such an order with no hierarchy:
Italy, France, Poland, Benelux, ..., Upper Austria, ... Switzerland, Tyrol, Croatia
The order I expect is my dictionary hierarchy, so:
Austria, Austria>Tyrol, Austria>Upper Austria, Benelux, Croatia, France, Italy, Poland, SwitzerlandDo You have any idea how to make the select list items appear in the dictionary hierarchy order?
Edit: Finder configuration:
