function tagadelic_get_weighted_tags in Tagadelic 6

Same name and namespace in other branches

1. 5 tagadelic.module \tagadelic_get_weighted_tags()
2. 7 tagadelic.module \tagadelic_get_weighted_tags()

Function that gets the information from the database, passes it along to the weight builder and returns these weighted tags. Note that the tags are unordered at this stage, hence they need ordering either by calling our api or by your own ordering data.

Parameters

$vids: Vocabulary ids representing the vocabularies where you want the tags from.

$steps: The amount of tag-sizes you will be using. If you give "12" you sill get six different "weights". Defaults to 6 and is optional.

Return value

An <em>unordered</em> array with tags-objects, containing the attribute $tag->weight.
