function lineage_taxonomy_overview_terms_submit in Taxonomy Lineage 7

Same name and namespace in other branches

1. 6 lineage.module \lineage_taxonomy_overview_terms_submit()

Submit handler for taxonomy_overview_terms (the admin term reordering form). Overrides handling so that we can update lineages after the new term weights are processed. This function is mostly a clone of taxonomy_overview_terms_submit, with the addition of lineage_update_all calls in the appropriate places.
