Yesterday we talked about counting the number of nodes by user.
Drupal 7 – Get the number of nodes by user

We could also use similar approach for counting the number of comments by user.

1. Add the following function in your theme template.php

function <theme>_get_user_comments_count($uid) {
  $query = db_select('comment', 'c');
  $query->condition('uid', $uid, '=');
  $query->condition('status', '1', '=');
  $query->addExpression('COUNT(1)', 'count');
  $result = $query->execute();

  if ($record = $result->fetchAssoc())
    return $record['count'];
  
  return 0;
}

function <theme>_get_user_nodes_count($uid) {
  $query = db_select('node', 'n');
  $query->condition('uid', $uid, '=');
  $query->condition('status', '1', '=');
  $query->addExpression('COUNT(1)', 'count');
  $result = $query->execute();

  if ($record = $result->fetchAssoc())
    return $record['count'];

db_query() returns a DatabaseStatementInterface object which has a function for retrieving the number of returned rows in the last SQL statement.

You could use the following piece of code to get the total number of nodes in Drupal.

$num_of_nodes = db_query('SELECT nid FROM {node}')->rowCount(); 

Done =)

Reference:

• Druapl API – db_query
• Drupal API – DatabaseStatementInterface
• Drupal API – DatabaseStatementInterface::rowCount
