The forum you posted in is for questions related to this site. Moving to proper forum.

 

Also, when posting code, enclose it within the forum's

 . . . 

BBCode tags.

Please use the [code][/code] tags around your code, as it helps make both your post and your code a lot easier to read. Also, you have to define what "not working" means, preferably with (complete) error messages. We don't know what you're trying, what you're expecting, or anything but what you explicitly tell us.

 

PS: I also recommend that you read this article.

Hi have following details of my code, I am making user login, if user click on submit button and if the user is valid the form will side with msg "You have logged in successfully " else it will display msg "incorrect username or password" , the msg will get display in DIV message tag and without reloading the page.so i am using ajax with support of jquery...
