I am trying to update userlevel when click on button. i have a page where it will display all users there i have change level button.by default every user will be in normal level(means 3) so when i click on a button it has to change to 5(lead
) and if i click again it has to change to 9(admin)

<div class="col-md-4">
<form method="post" class="change_userlevel" action="" onclick="getConfirmation(9);">
<input type="hidden" name="id" value="<?php echo $user->id; ?>">
<button type="submit" class="widget-icon" name="login"><span class='icon-arrow-up'></span></button>

Hope this will help you :
Your ajax code should be like this :
<script type='text/javascript'>
function getConfirmation(id)
{
if (id != '')
{
$.ajax({
url: "<?=site_url('User/change_status');?>",
type: "post",
data: {'id' : id},
success: function (response) {
alert('success');
//location.reload();
}
});
}
}
</script>
Your method change_status should be like this :
function change_status()
{
$id = $this->input->post('id');
$status = $this->db->select('userlevel')->where('id', $id)->get('users')->row()->userlevel;
if($status == 3)
{
$status = 5;
} else
{
$status = 9;
}
$data = array('userlevel' => $status);
$this->db->where('id', $id);
$this->db->update('users',$data);
echo TRUE;exit;
}
