There are two hook filter to include custom posts column in users.php.

• manage_users_columns
• manage_users_custom_column

1. manage_users_columns

This function provides an array of column names for argument.

The column name is as simple as adding an associative array.

In this case, the column is called contributes.

Example:

<?php
function contributes( $columns ) {
  $columns['contributes'] = __( 'Contributes', 'contributes' );
  return $columns;
}
add_filter( 'manage_users_columns', 'contributes' );
?>

2. manage_users_custom_column

syntax:

<?php apply_filters( 'manage_users_custom_column', string $output, string $column_name, int $user_id ); ?>

This filters display custom columns in the Users list table.

Parameters:

• $output – (string) column output.
• $column_name – (string) Pass column name.
• $user_id – (int) ID of currently-listed user.

Example:

<?php
function contributes_columns( $value, $column_name, $user_id ) {
  if ( 'contributes' != $column_name )//Replace 'contributes' with the column name from the filter you previously created
    return $value;
  global $wp_query;
  $posts    = query_posts('post_type=contribute&author='.$user_id.'&order=ASC&posts_per_page=30');//Replace post_type=contribute with the post_type=yourCustomPostName
  $posts_count = count($posts);
  $posts_count = "<a href='".site_url()."/wp-admin/edit.php?author={$user_id}&post_type=contribute'>{$posts_count}</a>";
    
  return $posts_count;
}

?>
