HABTM form validation in CakePHP

Submitted by Derick Ng on 12 January 2010 - 2:52am

Hi,

I have a Projects table and a Users table which are linked by a HABTM relation. In the "add" new Project page I have a multiple checkbox section to select Users for the new project. I want to have at least one User for the Project. What's the best way to approach this in CakePHP ?
