Automatická generácia SLUG bbPress

Tento jednoduchý plugin by mal pomôcť všetkým, ktorý sa rozhodli prejsť na bbPress a pritom sa snažia o migráciu z iného riešenia.

Nie som autorom pluginu, ale rozhodol som sa prípadnych záujemcov poistiť: http://www.simonwheatley.co.uk/2009/07/03/migration-to-bbpress-fix-topic-slugs/ Migrácia z phpBB bola hotovým utrpením, a funkčné SEO odkazy boli pre mňa zásadným faktorom. A keďže som chcel v čo najmenšom možnom množstve eliminovať stratu údajov, museli začať hodiny záloh a úprav v DB. Vopred upozrňujem, že prechod z iného riešenia (u mňa phpBB) može byť utrpením o to viac, ak sa snažíte o integráciu s WordPressom. Mňa zachránilo hľadanie a nájdenie pluginu…

Autorom pluginu je simonwheatley, ktorému týmto ďakujem. ( Thanks man! )

Tu pre záujemcov, ktorý sa dostali až sem poskytujem náprava vo forme pluginu. Postup je jednoduchý:

1. Vytvoriť súbor s ľubovolným názvom v priečinku my-plugins
2. Skopírovať php kód, ktorý je uvedený nižšie do vytvoreného súboru
3. uložiť
4. aktivovať plugin Creatre Slugs
5. Vymazať vami vytovrený súbor
