Hi, when at university i read that it is always best to have 3 layers of validation (client,server,database) which i have been doing in my applications.
I have now built a few web applications using extjs, which i think has excellent validation features. I am developing a new web application and starting to wonder why all the additional work is needed to put all the same validation into the server and the database when extjs does so well. i understand there must be a lot of security on the server and database, and any variables accepted by the server can have the type attribute set, but is it really necessary to replicate validation on all 3 layers? i have never had the validation on the server or database fire purely because extjs is so good! would appreciate others thoughts on this thanks ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:337352 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
