this is my JS page
function initialiseusers(){
$("#signupForm").validate({
    rules: {
        fname: "required",
        lname: "required",
        email:{
            required: true,
            email: true
        },
        password:{
            required: true,
            minlength: 5
        },
        phoneno:"required",
        roll:{
            required: true,
            minlength: 2
        },      
        messages: {
            fname:"Please enter your firstname",
            lname:"Please enter your lastname",
            email:"Please enter a valid email address",
            password:{
                required: "Please provide a password",
                minlength: "Your password must be at least 5 characters long"
            },
            phoneno:"Please enter your phoneno",
            roll:"Please enter your role"
        }
    }
         updateusers();// when the validation is over this function being called for updating the user.
});

But the validation is not working and when i click the save button.It directly saves Blank values inside my DB I downloaded the validation plugin and added it in the path also.,Any suggestions please?

The validation plugin binds to the form’s submit event, it’s not meant to be called in-line. Instead setup the validation, then call .valid() to check it, like this:

$(function() {
  $("#signupForm").validate({
    rules: {
        fname: "required",
        lname: "required",
        email:{
            required: true,
            email: true
        },
        password:{
            required: true,
            minlength: 5
        },
        phoneno:"required",
        roll:{
            required: true,
            minlength: 2
        }
    },      
    messages: {
        fname:"Please enter your firstname",
        lname:"Please enter your lastname",
        email:"Please enter a valid email address",
        password:{
            required: "Please provide a password",
            minlength: "Your password must be at least 5 characters long"
        },
        phoneno:"Please enter your phoneno",
        roll:"Please enter your role"
    }
  });
});
function initialiseusers(){
  if($("#signupForm").valid())
    updateusers(); //called if successfully validated
}

You can test it here, .validate() sets up the validation, it doesn’t execute it, .valid() does, and returns a boolean of if it was successful.
