Step - 2
Copy the following HTML code and save it as mywebapge.html in myajaxfolder
In the following code the layer <div id="validationresults"></div> displays the validation messages from the php action page mypage.php
Copy the following HTML code and save it as mywebapge.html in myajaxfolder
In the following code the layer <div id="validationresults"></div> displays the validation messages from the php action page mypage.php
<html lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">

<body>
<script>
$(document).ready(function(){
$("#myformsubmit").validate({
submitHandler : function(form) {
if($('#myformsubmit').submit(function(){return false;}))
{
$.ajax
({
type: 'POST',
url: $('#myformsubmit').attr('action'),
data: $('#myformsubmit').serialize(),
success: function(data)
{
$('#validationresults').html(data);
}
});
}
return false;
},
});
});
</script>
<form action="mypage.php" class="myform" id="myformsubmit" method="post">
Name <input id="namefrm" name="namel" type="text" />
Email ID <input id="emailfrm" name="email" type="text" />
Phone <input id="phonefrm" name="phone" type="text" />
<input type="submit" value="submit" />
</form>
In following layer we will get the validation results from action page (mypage.php)
<div id="validationresults"></div>
</head>
</html>
Step - 3
Copy the following PHP code and save it as mypage.php in myajaxfolder and the following php code doesn't send the form but gives some validation messages by checking the inputs
if name, email and phone is less than 4 charectors it gives proper validation messages
Copy the following PHP code and save it as mypage.php in myajaxfolder and the following php code doesn't send the form but gives some validation messages by checking the inputs
if name, email and phone is less than 4 charectors it gives proper validation messages
<?php
$name = $_POST['namel'];
$email = $_POST['email'];
$phone = $_POST['phone'];
if (strlen($name < 4)) {echo "Bad name";} if (strlen($email < 4)) {echo "Bad Email";} if (strlen($phone < 4)) {echo "Bad Input on Phone";} ?>
