Just create a project for the application folder, and link it to the core project (so you get code completion etc, do this in the project properties > inc path (or something similar))

There’s no point linking it to the sub folder in htdocs as you won’t gain anything, as AFAIK, you wouldn’t get auto complete anyway)

hi, I am new to code igniter and tried to build up IDE with eclipse. Now I put the CIcore file under /xampp/htdoc, it works. But the auto completion doesn’t, I do not know why ? can anybody help me ?  Thanks
