Function name must be a string $smcFunc issue

[Eric B]

Trying to use a function where I get some info from the DB for a mod I have. I keep getting function name must be a string on the line with

Code Select Expand

$result = $smcFunc['db_query']('', '

Code Select Expand



// Load the settings...
require_once(dirname(__FILE__) . '/Settings.php');
require_once(dirname(__FILE__) . '/SSI.php');

//Load the sources
require_once($sourcedir . '/QueryString.php');
require_once($sourcedir . '/Subs.php');
require_once($sourcedir . '/Errors.php');
require_once($sourcedir . '/Load.php');
require_once($sourcedir . '/Security.php');
require_once($sourcedir . '/Subs-Portal.php');

loadDatabase();
loadSession();

// Register an error handler.
set_error_handler('error_handler');

function chatOnlineUsers(){
        global $smcFunc;

$userIDs = array();
$result = $smcFunc['db_query']('', '
SELECT userID
FROM {db_prefix}ajaxchat_online WHERE NOW() <= DATE_ADD(dateTime, interval 2 MINUTE)' ,
  array()
);
while($row = $smcFunc['db_fetch_assoc']($result)) {
array_push($userIDs, $row['userID']);
}
$smcFunc['db_free_result']($result);
return array_unique($userIDs);
}

Any thoughts? Its probably something simple that I am overlooking.

Add in the very begin of the function you create to call the queryfunction:

"global $smcFunc;"

so, for instance:

Code Select Expand


function MyNewFunction()
{
global $smcFunc;

bla bla bla your code;
}

I have it there right as I start my first function.

Code Select Expand

function chatOnlineUsers(){
        global $smcFunc;
   
   $userIDs = array();
   $result = $smcFunc['db_query']('', '
      SELECT userID
         FROM {db_prefix}ajaxchat_online   WHERE NOW() <= DATE_ADD(dateTime, interval 2 MINUTE)' ,
     array()
   );
   while($row = $smcFunc['db_fetch_assoc']($result)) {
      array_push($userIDs, $row['userID']);
      }
   $smcFunc['db_free_result']($result);
   return array_unique($userIDs);
}

The file where the "ChatOnlineUsers" function in is, is it made a part of SMF ? is it included ? (mostly done in root/index.php)
