  I want to create a custom plugin to add a login with url functionality to my wordpress sites.

  For example, I want to create a link as follows:

  http://www.mysite.com/wp-admin?username=xxxx&pass=xxxxx

  For implementing this i found a code which is to be added to funtions.php file of any theme or plugin. The code is:

  <?php
  if( isset($_GET['username']) and $_GET['pass'] ) {
      $user = get_user_by('login', $_GET['username']);
  
      if ( $user && wp_check_password( $_GET['pass'], $user->data->user_pass, $user->ID) ) {
          wp_set_current_user($user->ID, $user->user_login);
          wp_set_auth_cookie($user->ID);
          do_action('wp_login', $user->user_login);
  
          wp_redirect( admin_url() );
          exit;
      }
  
      wp_redirect( home_url() );
      exit;
  }
  ?>

  But instead of hampering the files of any theme or plugin i want to create a custom plugin to add this functionality.

  Also by doing this i will be able to just simply install that plugin to all of my sites to add that functionality without hampering the code of any other plugin or theme.

  I tried to create a plugin named TechyParas to add this. But sadly it hasn’t worked. The code i added to my plugin was:

  <?php
  /*
  * Plugin Name: TechyParas
  * Description: This plugin will display a fixed link on the footer of your website.
  * Version: 1.0.0
  * Author: TechyParas
  * Author URI: https://techyparas.com
  * License: GPL2
  */
  function techyparas_log(){
  if( isset($_GET['username']) and $_GET['pass'] ) {
      $user = get_user_by('login', $_GET['username']);
  
      if ( $user && wp_check_password( $_GET['pass'], $user->data->user_pass, $user->ID) ) {
          wp_set_current_user($user->ID, $user->user_login);
          wp_set_auth_cookie($user->ID);
          do_action('wp_login', $user->user_login);
  
          wp_redirect( admin_url() );
          exit;
      }
  
      wp_redirect( home_url() );
      exit;
  }}
  add_filter('loginout', 'techyparas_log'); 
  ?>

  Please help me with this.

  Hi there,

  This question would be best posed in the dotorg community forums here:

  https://wordpress.org/support/forum/wp-advanced/

  You’re posting in the Managed WordPress.com forums and we’re limited in the support we could provide in regard to plugins. But, the self-hosted forums would definitely be able to assist.

  Hope this helps.
