number of visitors online

[Gregor]

Hi,

Found some php-code  to use for showing the number of online users http://www.roscripts.com/How_many_visitors_online_PHP_script-108.html
From what I read, it's free to use:

Create a file called "visitors.txt" and upload it to the root of your site. Also upload the following php-code:

Code: Select all

<?php
$dataFile = "visitors.txt";

$sessionTime = 30; // this is the time in **minutes** to consider someone online before removing them from our file

//Please do not edit bellow this line

error_reporting(E_ERROR | E_PARSE);

if(!file_exists($dataFile)) {
	$fp = fopen($dataFile, "w+");
	fclose($fp);
}

$ip = $_SERVER['REMOTE_ADDR'];
$users = array();
$onusers = array();

//getting
$fp = fopen($dataFile, "r");
flock($fp, LOCK_SH);
while(!feof($fp)) {
	$users[] = rtrim(fgets($fp, 32));
}
flock($fp, LOCK_UN);
fclose($fp);


//cleaning
$x = 0;
$alreadyIn = FALSE;
foreach($users as $key => $data) {
	list( , $lastvisit) = explode("|", $data);
	if(time() - $lastvisit >= $sessionTime * 60) {
		$users[$x] = "";
	} else {
		if(strpos($data, $ip) !== FALSE) {
			$alreadyIn = TRUE;
			$users[$x] = "$ip|" . time(); //updating
		}
	}
	$x++;
}

if($alreadyIn == FALSE) {
	$users[] = "$ip|" . time();
}

//writing
$fp = fopen($dataFile, "w+");
flock($fp, LOCK_EX);
$i = 0;
foreach($users as $single) {
	if($single != "") {
		fwrite($fp, $single . "\r\n");
		$i++;
	}
}
flock($fp, LOCK_UN);
fclose($fp);

//:auto; background-color:#fff
if($uo_keepquiet != TRUE) {
	if($i = 1) {
	echo '<div style="padding:5px; margin:auto"><b>' . $i . ' bezoeker online</b></div>';	
	} else {
		echo '<div style="padding:5px; margin:auto"><b>' . $i . ' bezoekers online</b></div>';
	}
}
?>

Create a UDT, in my case visitors, that has the following code:

Code: Select all

include_once "/home/gregor/domains/uisge-beatha.eu/public_html/visitors.php";

Place the tag {vistors} somewhere in your template. I'm about to place it in the footer. To see an example www.uisge-beatha.eu At the moment it's placed on the right hand site on the home page.

Good luck,
Gregor

Based on one of the other topics, an easier method is to put the php-code direct into the udt, so visitor.php does not to be placed on the server. The code for the UDT is without the

.

Code: Select all

$dataFile = "visitors.txt";

$sessionTime = 30; // this is the time in **minutes** to consider someone online before removing them from our file

//Please do not edit bellow this line

error_reporting(E_ERROR | E_PARSE);

if(!file_exists($dataFile)) {
	$fp = fopen($dataFile, "w+");
	fclose($fp);
}

$ip = $_SERVER['REMOTE_ADDR'];
$users = array();
$onusers = array();

//getting
$fp = fopen($dataFile, "r");
flock($fp, LOCK_SH);
while(!feof($fp)) {
	$users[] = rtrim(fgets($fp, 32));
}
flock($fp, LOCK_UN);
fclose($fp);


//cleaning
$x = 0;
$alreadyIn = FALSE;
foreach($users as $key => $data) {
	list( , $lastvisit) = explode("|", $data);
	if(time() - $lastvisit >= $sessionTime * 60) {
		$users[$x] = "";
	} else {
		if(strpos($data, $ip) !== FALSE) {
			$alreadyIn = TRUE;
			$users[$x] = "$ip|" . time(); //updating
		}
	}
	$x++;
}

if($alreadyIn == FALSE) {
	$users[] = "$ip|" . time();
}

//writing
$fp = fopen($dataFile, "w+");
flock($fp, LOCK_EX);
$i = 0;
foreach($users as $single) {
	if($single != "") {
		fwrite($fp, $single . "\r\n");
		$i++;
	}
}
flock($fp, LOCK_UN);
fclose($fp);

//:auto; background-color:#fff
if($uo_keepquiet != TRUE) {
	if($i = 1) {
	echo '<div style="padding:5px; margin:auto"><b>' . $i . ' bezoeker online</b></div>';	
	} else {
		echo '<div style="padding:5px; margin:auto"><b>' . $i . ' bezoekers online</b></div>';
	}
}

Couldn't get this to work at first on CMSMS 1.2.3 but all working now.

Here's a version that works on 1.2.3, that outputs in English and doesn't force any formatting on the output.

I put it in the Footer and it works fine.

I added it as a "User Defined Tag" called visitor and called it from the footer by adding {visitor} to the end of the copyright line.
