How do I send a $_POST request to my WordPress application from an external website, and handle it here? I want to send user credentials, along with additional login data, to perform an auto-login.

  1. Do I need to define a new URL for handling the $_POST request?
  2. Which action hook do I need to use for handling such a request?

1. Do I need to define a new URL for handling the $_POST request?

No, you don't need to define new URL.

2. Which action hook do I need to use for handling such a request?

You can use init hook.

Sample code

function my_theme_send_email() {

    if ( isset( $_POST['email-submission'] ) && '1' == $_POST['email-submission'] ) {

        // Send the email...

    } // end if

} // end my_theme_send_email
add_action( 'init', 'my_theme_send_email' );

Now you can call your website with POST required POST parameters.

Update:

  • init is used when you're handling requests within the WordPress site. Not the requests coming from an external source. This is what the Codex says: Fires after WordPress has finished loading but before any headers are sent. Sep 25, 2015 at 11:58
  • I think you misunderstood it. When you call your website url, WordPress is already initialized. And it will handle request. Sep 25, 2015 at 12:35

  • But then the email address is still a $_GET parameter in the same context, right? I need to send the $_POST request from an external URL. The website will not necessarily be loaded. Sep 25, 2015 at 13:06
  • How does $_GET or $_POST make any difference with WordPress loading? I think you first try your code before arguing. Sep 25, 2015 at 13:10
