Magento

I have added using a combination of the Mage:getModel(’catalog/product’) and mySQL queries (to update other parts, such as quantity and category id).  But for some reason my product is still not showing up in the storefront....is there something I need to do (i.e reindex the inventory) ?  If so, how can I do it direct from PHP code?

Thank you for your help

hey,

why are you trying to use direct sql and not the import functions in magento?. I think you could be making things alot harder than they should be..
are you trying to add new products or update?. Your question isnt very clear on this

cheers
