Usually, the information you submit is checked on the server side and you will be asked to fix possible errors, if any. This procedure is called form validation.

Search google for regex email validation and you will probably find some good solution.

For email validation
->It is done under the script tag in "javascript"
-> you can divide the email validation in two parts
->first validate for empty text field
-> validate using regular expressions in PHP for the symbols used in email id format and a valid domain name.

There are two ways to validate email viz 1>Using javascript (client side)2>Using any server side language

In javascript
function validate(form_id,email) {

var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
var address = document.forms[form_id].elements[email].value;
if(reg.test(address) == false) {

alert('Invalid Email Address');
return false;
}
}
