Welcome to WebmasterWorld Guest from 188.8.131.52
I've tried PHPdig and got it working up to the part where I try to get a search box in my main template.. I end up with a blank page or some error.
So I've looked around and can't really find any other alternatives that use MySQL and was hoping someone knew of one.
There was one that I wanted to try mngosomethingorother but it was perl and required command line to install I think so no go.
We use ht://Dig [htdig.org] for this kind of thing but it's not the easiest to set up for a newbie.
You could cronjob the spider, but I choose to use the admin toolbox instead. You just go to the admin page - I do it before leaving the office every Friday - click a button, and off it goes.
