I am working in a migration from fireboard to vBulletin and this migration involved a certain amount of custom scripts for those functions unsupported by impex; i am running those scripts locally on my machine before to upload the finished database on the server.
Among all the script, i did write a script to transport attachments from fireboard to vbulletin; the script is written trying to understand how the attachment system works from the database interactions, transform the attachement in a BLOB and update it in the filedata table - following impex instructions to store attachments in the DB - and did produced a good amount of empty attachment links on the forum; would like to know what modifications should i do to make the import work properly, thanks.
PHP Code:
<?php
/**
* Retrieve fireboard attachments,
* upload it as BLOB and insert it into related vBulletin threads
* hope this works ^^;
