PHP function in a template
I have this users.php function code to list online users. I would like to include this on a non-vb page that uses templates.
PHP Code:
<?
chdir('./');
require_once('./global.php');
// ---------------------------------------------------
// Start Globalized Function - LoadTemplate
// ---------------------------------------------------
function LoadTemplate($template = ""){
$template = "vBExternal/{$template}";
if(!file_exists($template)){
RunError("System was unable to find the template '{$template}'");
}
if(!$Handler = fopen($template,'r')){
RunError("System was unable to open the template '{$template}'");
}
$template = fread($Handler,filesize($template));
fclose($Handler);
return $template;
}
// ---------------------------------------------------
// Start Globalized Function - RunError
// ---------------------------------------------------
function RunError($message = ""){
echo "<font size='1' face='verdana'>There was an error while processing vBExternal:<br />{$message}</font>";
exit;
}
// ---------------------------------------------------
// End Globalized Function - RunError
// ---------------------------------------------------
// ---------------------------------------------------
// Start Globalized Function - ParseTemplate
// ---------------------------------------------------
function ParseTemplate($template, $parser = array(), $doGlobals = 0){
global $vbulletin;
if(is_array($parser)){
foreach($parser as $find => $replace){
$template = str_replace("{".$find."}", $replace, $template);
}
} else if($doGlobals){
$RepGlobals = array(
'url' => $vbulletin->options['bburl'],
);
foreach($RepGlobals as $find => $replace){
$template = str_replace("{".$find."}", $replace, $template);
}
}
return $template;
}
// ---------------------------------------------------
// End Globalized Function - ParseTemplate
// ---------------------------------------------------
function output_UsersOnline(){
global $db, $Data, $vbulletin;
// Load Template
$Template = LoadTemplate("users_online.html");
$cache = array();
// Collect Data
$datecut = TIMENOW - $vbulletin->options['cookietimeout'];
$UsersOnline = $db->query("
SELECT
user.username, (user.options) AS invisible, user.usergroupid,
session.userid,
IF(displaygroupid=0, user.usergroupid, displaygroupid) AS displaygroupid
FROM " . TABLE_PREFIX . "session AS session
LEFT JOIN " . TABLE_PREFIX . "user AS user ON(user.userid = session.userid)
WHERE session.lastactivity > $datecut and user.userid > 0
" . iif($vbulletin->options['displayloggedin'] == 1, "ORDER BY username ASC") . "
");
while($User = $db->fetch_array($UsersOnline)){
if(!$cache[$User['userid']]){
$cache[$User['userid']] = $User['userid'];
$Data .= ParseTemplate($Template,
array(
'userid' => $User['userid'],
'username' => $User['username'],
)
);
}
}
unset($cache);
doOutput();
}
function doOutput(){
global $Data, $vbulletin;
$Data = str_replace('images/',"{$vbulletin->options[bburl]}/images/",$Data);
echo ParseTemplate($Data,"",1);
$Data = "";
}
?>
That php file works if you include output_UsersOnline() in the file itself.
What would be the proper way construct this code in a plugin so I can call it in a template with a variable ie; $onlineusers |
