Hi,

I have a wordpress site, which has 2 back ends for the admin to administer content.
-The wordpress admin login
-a php content management software.
My question is, how can I add this php cms to a wordpress dashboard? What options are available and how can I do it.

its hard, really hard.

Look into writing a wordpress plugin, if not it might be easier to keep it separate on another page.

Not really sure why you have the two seperate anyway, Wordpress can be manipulated to work like a CMS.

You coud possibly make a program which integrates the two databases and does a checkup every 1-2 hours posting the changes

The 2 cms's are updating the same database
