My friend recently gave me his website, but I am new to php. He has a section on his site that I can edit through an admin panel but I can not use HTML in the box. How can I change this to incorporate HTML? Do i have to use a source file such as a style.css file?
You may want to look into integrating a WYSIWYG text editor into your admin panel. I used one from CKeditor. It’s free, allows you to add html source code, and is very easy to install and configure. More info available through here: http://ckeditor.com/demo
