Get current URL inside ajax callback?

Question

I have created custom module called mymodule.

In this URL localhost/mymodule/name, I have this field:

$form['name'] = array(
  '#title' => t('Enter name'),
  ...
  '#ajax' => array(
    'event' => 'blur',
    'callback' => 'mymodule_ajax_callback',
    'wrapper' => 'my-wrapper',
    'method' => 'replace',
  ),
  ...
);

My ajax callback is successfully called:

function mymodule_ajax_callback($form, &$form_state) {
  ...
  return ...
}

However, inside 'mymodule_ajax_callback', I need to get the current URL of the page which is localhost/mymodule/name. Currently it returns system/ajax which is how Drupal works by nature.

How to get the current URL inside the ajax callback?

Answer 1

As said by @Jayendra Kainthola
You need to store current path value in a session

$_SESSION['current_path'] = current_path();

Then use it inside your callback function as follows :

function mymodule_ajax_callback($form, &$form_state) {

$current_path = $_SESSION['current_path']  ;//gives the current path

}

Answer 2

$form['#action'] can be used in order to meet the requirement of the Url. And then used as one want.

$form['#action']

Like:

function xyz_ajax_function($form, &$form_state){
  if(strpos($form['#action'], YOUR_URL_WANT_TO_CHECK)){
    echo 'yes';
  }else{
    echo 'no';
  }
}
