getting list of users in Drupal 7 using PHP - php

Question

How can I fetch user names from a Drupal 7 database using PHP?
See this:
Is it possible to use the Drupal api to get a list of users?
This is for Drupal 6 and I have tried this but it says
Call to undefined function db_fetch_object()
Here is my code:
$result = db_query("SELECT name AS users_name FROM {users}");
while($row = db_fetch_object($result)) {
print_r($row);
}

Answer 1

Lets give it a try
$query = db_select('users', 'u');
   $query->fields('u', array('name'));
   $result = $query->execute();
   while($record = $result->fetchAssoc()) {
        print_r($record['name']);
   }

Answer 2

In Drupal 7 you can fetch all the users using entity_load,
To get the user names alone use the following,
$users = entity_load('user');
$user_names = array();
foreach ($users as $user_id => $user) {
$user_names[] = $user->name;
}

Answer 3

user_load_multiple
Example from modules\profile\profile.pages.inc :
$users = user_load_multiple($uids);
$content = '';
foreach ($users as $account) {
$profile = _profile_update_user_fields($fields, $account);
$content .= theme('profile_listing', array('account' => $account, 'fields' => $profile));
}
Note that in drupal 7 all things happen via entity. It's not so fast, but flexible...

Answer 4

$query = db_select('users', 'u');
$query
->condition('u.uid', 0, '<>')
->fields('u', array('name'));
$result = $query->execute();
Here's the whole documentation for Drupal 7 Database api

Answer 5

Your code was almost correct if you had changed your while statement to read
while ($result as $row)
db_fetch_object is no longer needed in d7
it would have worked. Although db_select calls specified in this post will work, they require more overhead and should be avoided unless you are trying to generate dynamic queries. Also see: http://drupal.org/node/224333 for info on how the apis have chaned between d6 and d7. A search for db_fetch_object on this page would've given this info.

Answer 6

My example code to get the list of users from drupal site,
$all_users = entity_load('user');
foreach($all_users as $value) {
$user_list = (array)$value;
$users[$user_list['uid']] = $user_list['name'];
}
Now you can get the answer from the array variable $users.
For example if you want to list all the user other than administrator (default user) means use the below example:
$all_users = entity_load('user');
foreach($all_users as $value) {
$user_list = (array)$value;
if($user_list['uid'] > 1) {
$users[$user_list['uid']] = $user_list['name'];
}
}
In the above both example, the id of each user is placed as array index and the name of each usder is saved as array value.

Answer 7

Drupal 7 introduces a new concept of Entity.
User also included in Entity now.
You can use following function entity_load() to get the details of all entities.
To fetch the usernames in array :
$users = entity_load('user');
$usernames = array();
foreach($users as $id => $user){
$usernames[$user->uid] = $user->name;
}
print_r($usernames);
Thanks

A Better way
function GetAllActiveUsers() {
$query = new EntityFieldQuery();
$query->entityCondition('entity_type', 'user')
->propertyCondition('status', 1);
$results = $query->execute();
$uids = array_keys($results['user']);
return $uids;
}
This will return all active users and use the code in a function to use it as a helper

Answer 9

Try this:
$query = db_select('users', 'u')
->fields('u')
->execute();
while($result = $query->fetchAssoc()) {
print_r($record['name']);
}

Answer 10

You can try this as well,
$query = db_select('users', 'u');
$query->fields('u', array('uid, name'));
$result = $query->execute();
while($record = $result->fetchAssoc()) {
$account = user_load($record['uid']);
if($account->uid){
print $account->name;
}
}

Answer 11

Simplified example with fetchAll():
$users = db_select('users', 'u')
->fields('u', array('uid'))
->execute()
->fetchAll();
foreach ($users as $user) {
$full_user = user_load($user->uid);
//do your stuff here
}
