a . Copy and paste the FCK editor folder (which holds the files related to the FCK editor) into your project folder.
b. Use the following code for including FCK editor.
$oFCKeditor = new FCKeditor("message") ;
$oFCKeditor->BasePath = '../FCKeditor/' ;
Here message is the name of the HTML element, you can give your own name as per your need. This name can be used as any other HTML element for getting the value from $_POST.
It seems FCKeditor is not working in Chrome.
