I have released an updated version at http://sheldon.lendrum.co.nz/codeigniter-spaw-editor-tabs_411/10/. This new version allows CodeIgniter and SPAW TABS !
Recently I have been working on a large project for a National Sporting team, It has been a process and it is almost finished.
As part of this system, we have developed an extended custom content management system.
Finding a WYSIWYG Editor for these types of sites is a tricky thing. Your editor of choice needs to be complex enough to let the user Manage their site, but not too hard that they can’t and don’t manage it, yet not give them so many options that your beautiful design gets listed on some of the ‘worst’ design sites due to ‘Crazy Customisation’, bright, huge highlighted words, 5mb images on every page and so on… like a ‘Client goes Crazy’ Video.
WordPress uses TinyMCE editor from MoxieCode, which is what we first implemented, but the design agency requested that they can add inline images in to the content. ( Bad thoughts crept in to my mind of a horror site coming out ) but I decided this would be a nesscarry change.
I went back to an old faithful that Ryan & I have used for years on other CMS’s.
The issue with this is it uses it’s own class, and interferes with CodeIgniter, the PHP FRamework that we are developing this site in.
After some googling, I found a solution on the CodeIgniter Wiki. After installing it, I first found I needed some small customizations, and that it wasn’t a new version, and didn’t have Safari support, which both us developers, and the advertising agency use. So I went to work on repackaging SPAW 2.0.8.1 for CodeIgniter with a few extra plugins.
