I'm looking for a bit of help with setting up WordPress alongside another website. Long story short, my employer has had the same website for the past 10 years and the whole thing looks really dated. Finally I managed to convince them to update the site and offered I will do one for free in WordPress (building up a portfolio, improving skills).
Problem - I want the 'old' website (done in Dreamweaver, using a mix of html & php) to be still visible to the public, while I develop something new in WordPress. Is it possible to set up an independent WordPress installation in a subfolder, on the same domain? I've found a codex article explaining how to do this (http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory) but I'm not sure if the end result will be a 'standalone' installation, alongside the 'old' website. In other words - I want to make absolutely sure I won't mess up the 'old' website in the process of installing WordPress.
I did contact my host for help, but they quoted £110 to do what I'm asking for - ridiculous, seeing how WordPress can be installed in 5 minutes as long as the person knows what they are doing.
What I want is for the old html/php website to be at http://www.example.org, while the 'in development' WordPress site to be at http://www.example.org/wordpress. I want both websites to be visible - one for the public, one for me, for testing purposes.
If this is possible, then I'm assuming the homepage of the wordpress installation would be at http://www.example.org/wordpress/index.php, while the Dashboard will be at http://www.example.org/wordpress/wp-admin/admin.php?
Also, if anyone can think of any alternatives (e.g. developing a WordPress website offline, then publishing it in a painless way) then any suggestions will be appreciated.
