I m validating a data by clicking the submit button and then again loading the views. I want just to show the errors on the page before loading the controller. Its is not a form validation. it is just a data validiation.

I think you can do the validation using AJAX.
Comments
in view page
<script type="text/javascript">
$(document).ready(function() {
/// make loader hidden in start
$('#loading').hide();
$('#email').blur(function(){
var email_val = $("#email").val();
var filter = /^[a-zA-Z0-9]+[a-zA-Z0-9_.-]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$/;
if(filter.test(email_val)){
// show loader
$('#loading').show();
$.post("<?php echo site_url()?>/user/email_check", {
email: email_val
}, function(response){
$('#loading').hide();
$('#message').html('').html(response.message).show().delay(4000).fadeOut();
});
return false;
}
});
});
</script>
in controller function
public function email_check()
{
// allow only Ajax request
if($this->input->is_ajax_request()) {
// grab the email value from the post variable.
$email = $this->input->post('email');
// check in database - table name : tbl_users , Field name in the table : email
if(!$this->form_validation->is_unique($email, 'tbl_users.email')) {
// set the json object as output
$this->output->set_content_type('application/json')->set_output(json_encode(array('message' => 'The email is already taken, choose another one')));
}
}
}
