  $count_key = 'post_views_count';
  $count = get_post_meta($postID, $count_key, true);
  if($count=='') {
    delete_post_meta($postID, $count_key);
    add_post_meta($postID, $count_key, '1');
    return "1";
  } // if($count=='')
return $count;
} // getPostViews()

/******************************************************************
 * Set the number of views for a specific page / post
 * Call this function in single.php: setPostViews(get_the_ID());
 ******************************************************************/
function setPostViews($postID) {
  $count_key = 'post_views_count';
  $count = get_post_meta($postID, $count_key, true);
  if($count=='') {
    $count = 1;
    delete_post_meta($postID, $count_key);
    add_post_meta($postID, $count_key, '1');
  } else {
    $count++;
    update_post_meta($postID, $count_key, $count);
  } // if($count=='')

 ******************************************************************/
add_filter('manage_posts_columns', 'posts_column_views');
add_action('manage_posts_custom_column', 'posts_custom_column_views',5,2);
function posts_column_views($defaults) {
  $defaults['post_views'] = __('Views');

} // posts_column_views()

function posts_custom_column_views($column_name, $id) {
  if($column_name === 'post_views') {
    echo getPostViews(get_the_ID());
  } // if($column_name === 'post_views')

WordPress – Reset password in database

How to reset a WordPress password directly in the database (using PHPMyAdmin)?

METHOD 1

Go to
https://www.md5hashgenerator.com/
and calculate the MD5 hash for the password you want to use.

Open the WordPress users table (in PHPMyAdmin) wp-users and paste the MD5 hash into your user_pass field.

 

METHOD 2 (SNEAKY ONE!)

  • Open the WordPress users table (in PHPMyAdmin) wp-users.
  • Select a user with Administrator rights.
  • Back up the (encrypted) password and email address of that user in a text file.
  • Change the email address to your own email address.
  • Go to the WP login page and click the ‘Lost your password?’ link.
  • Enter your own email address (the one you entered in the database).
  • Click the ‘reset password’ link in the email that you receive from WordPress.
  • Enter a new password and you are in!
  • Create a new user for yourself, with Administrator rights.
  • In PHPMyAdmin, restore the password and email for the user you abused.
  • DONE 😉

WordPress – Disabling all Plugins using the Database

If you need to disable all plugins because one of the plugins is causing a problem and therefore you cannot get to the plugins page via the Dashboard (so-called “White Screen of Death”), you can disable all plugins directly in the database.

Locate the option name “active_plugins” (in the wp_options table)
Copy the value and paste it into some text editor (as a backup).
Change the value to:

a:0:{}
