validation for user registration?

[Saurabh Kolte]

I have a user registration form in that I mentioned email id as my mandatory field. say I am entering the user details with email

Id.

so for that I wanted to use a client script or glideAjax which will be used for restricting of entering the same email id again.

so what script I use for that??? does bussiness rule will be helpful in this case?

Hi Saurabh,

Based on your req you can achieve this req either with client script or business rule.

Client script approach : You can have a OnChange client script which will pass the current email from the form and then do the validation at the server(GlideAjax) and return the value back to the client.

Business rule approach : You can GlideRecord the sys_user table and pass the current email value and then do the validation.

Please let me know if you have any questions.

Hi Saurabh,

As promised, here is the code.

Client Script : I've done validation on submit. However you change as per your req.

function onSubmit() {

   //Type appropriate comment here, and begin script below

   var userEmail = g_form.getValue('u_email');

   var ga = new GlideAjax('HelloWorld');

   ga.addParam('sysparm_name','helloWorld');

   ga.addParam('sysparm_user_name', userEmail);

   ga.getXML(HelloWorldParse);



   function HelloWorldParse(response) {

   var answer = response.responseXML.documentElement.getAttribute("answer");

   alert(answer);

   if(answer == 'true')

   {

   alert('Email already exists');

   }

   }

}

Now create a script include:

Name : HelloWorld

Client Callable : True

Script :

var HelloWorld = Class.create();

HelloWorld.prototype = Object.extendsObject(AbstractAjaxProcessor, {

   helloWorld: function() {

   var answer = 'false';

   var usrEmail = this.getParameter('sysparm_user_name');

   var gr = new GlideRecord('sys_user');

   gr.addQuery('email',usrEmail);

   gr.query();

   while(gr.next())

   {

   answer = 'true';

   }

   return answer;

   },



   _privateFunction: function() { // this function is not client callable



}





});

Also I've developed this on below demo instance.

Username : admin

Password : admin

Steps for testing : go to Incident form there I've created an email field. Onsubmit of the form it will validate and give an alert.

Please change the naming conventions and modify the script as per your req.
