I have login through ajax to my application. When user before login, try access admin home page(http://localhost/ci3/admin/Adminhome) that time it redirects him to admin login page(http://localhost/ci3/admin/Adminlogin). After login as user and try to access admin home page, he will get success. Now I want to find ajax request. I have tried something like below,
<?php
class Admin_controller extends CI_Controller{
function __construct()
{
parent::__construct();
$this->load->model("Adminmodel","",true);
$this->load->library('user_agent');
$adminId = $this->session->userdata('cp_adminid');
if($adminId == null){
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH'])=='xmlhttprequest'){
echo "it is ajax request";
} else {
echo "it is not ajax request";
}
} else {
}
}
?>
$('#adminloginform').validate({
errorClass: 'error',
validClass: 'valid',
errorPlacement: function(error, element) {
error.insertAfter(element);
},
rules: {
username:{
required: true,
},
password:{
required: true,
minlength: 6,
}
},
messages:{
username: {
required: "Email is required",
},
password: {
required: "Password is required",
minlength: "Atleast 6 characters",
}
},
submitHandler: function(){
var admin=$('#adminloginform').serializeArray();
$.post("<?php echo base_url()?>admin/Adminlogin/auth",admin,function(data){
if((data.result == 1) && (data.row.view == 1 || data.row.edit == 1 || data.row.add == 1 || data.row.deleteRole == 1 )){
window.location="<?php echo base_url()?>admin/Adminhome";
} else if (data.result == 1) {
window.location="<?php echo base_url()?>admin/Userhomepage";
} else {
noty({ text: 'Username or Password is incorrect',type: 'error',modal:true,timeout:1000});
}
//$(".simplemodal-close").trigger("click");
},"json");
}
});
If you are using it within the application than why not to create a flag. When you call from ajax set it to true and by-default make it false.
class Admin_controller extends CI_Controller{
function __construct($AjaxFlag = false)
{
parent::__construct();
$this->load->model("Adminmodel","",true);
$this->load->library('user_agent');
$adminId = $this->session->userdata('cp_adminid');
if($adminId == null){
if($AjaxFlag){
echo "it is ajax request";
} else {
echo "it is not ajax request";
}
} else {
}
}
Check in controller function
function function_name()
{
if(is_ajax_request()){
}
}
Use helper to check this ajax request
function is_ajax_request()
{
$CI = & get_instance();
if(!$CI->input->is_ajax_request()) {
exit('No direct script access allowed');
}
else
{
return true;
}
}
