If you are using php with html then you can use the following:- Code: Select all
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8" />
<script type="text/javascript">
//Client-side validation example
function validate() {
var fname = document.getElementById("fname");
var lname = document.getElementById("lname");
var email = document.getElementById("email");
var emptyerror = "Please enter value"
var erroremail = "please enter valid email address";
if (fname.value == "" || fname.value == emptyerror) {
fname.value = emptyerror
}
else {
fname.value = "";
}
if (lname.value == "" || lname.value == emptyerror) {
lname.value = emptyerror
}
else {
lname.value = "";
}
if (email.value == "" || email.value == emptyerror) {
email.value = emptyerror
}
else {
email.value = "";
}
if (!(email.value == emptyerror || email.value == erroremail))
if (!/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/.test(email.value)) {
email.classList.add("errordiv");
email.value = erroremail;
}
}
</script>
</head>
<body>
<h1>Trainee Registration Form </h1>
<h3> First Name: <input id="fname" type="text" value="" name="name" class="required" /> </h3>
<h3> Last Name: <input id="lname" type="text" value="" name="name" class="required" /> </h3>
<h3> Email ID: <input id="email" type="text" value="" name="email" class="required" /> </h3>
<input class="submit" type="button" name="submit" value="Submit" onclick="validate()" />
<span id="result"></span>

I recommend to use php frameworks for this. there are any good simple systems on the market - e.g. the open source framework rexo.ch. here you find a solution to exactly what you want (username and password instaed of username and email).Page 1 of 1
