A web badge is a small image or text used on websites to promote web standards, products used in the creation of a web page or product, to indicate a specific content license that is applied to the content or design of a website, to comply with an application’s terms of service, to encourage your visitors to check your social network status, or even to display visitor’s informations. such as ip address, user agent, hostname etc.

Today’s story, we’ll make a badge for visitor’s ip address using php and javascript. This badge, for an example:
[cfields]v_ip_badge[/cfields]

create a php script called ipaddr.php as follows

<?php
if ( isset($_SERVER["REMOTE_ADDR"]) )    {
	$ip=$_SERVER["REMOTE_ADDR"] . ' ';
} else if ( isset($_SERVER["HTTP_X_FORWARDED_FOR"]) )    {
	$ip=$_SERVER["HTTP_X_FORWARDED_FOR"] . ' ';
} else if ( isset($_SERVER["HTTP_CLIENT_IP"]) )    {
	$ip=$_SERVER["HTTP_CLIENT_IP"] . ' ';
}
$IpAddr = $ip;
?>

if (typeof(v_ip_BackColor)=="undefined")
  v_ip_BackColor = "white";
if (typeof(v_ip_ForeColor)=="undefined")
  v_ip_ForeColor= "black";
if (typeof(v_ip_FontPix)=="undefined")
  v_ip_FontPix = "16";
if (typeof(v_ip_DisplayFormat)=="undefined")
  v_ip_DisplayFormat = "You are visiting from:<br>IP Address: %%IP%%";
if (typeof(v_ip_DisplayOnPage)=="undefined" || v_ip_DisplayOnPage.toString().toLowerCase()!="no")
  v_ip_DisplayOnPage = "yes";

v_ip_HostIP = "<?php echo $IpAddr ?>";

if (v_ip_DisplayOnPage=="yes") {
  v_ip_DisplayFormat = v_ip_DisplayFormat.replace(/%%IP%%/g, v_ip_HostIP);
  document.write("<table border='0' cellspacing='0' cellpadding='5' style='background-color:" + v_ip_BackColor + "; color:" + v_ip_ForeColor + "; font-size:" + v_ip_FontPix + "px'><tr><td>" + v_ip_DisplayFormat + "</td></tr></table>");
}


The script above contains a few lines of PHP and JavaScript code. The first 10 lines of php code contains a function to retrieve value of visitor’s ip, whether they use a proxy, or directly connected to our website and passed to $IpAddr variable.

<?php
if ( isset($_SERVER["REMOTE_ADDR"]) )    {
	$ip=$_SERVER["REMOTE_ADDR"] . ' ';
} else if ( isset($_SERVER["HTTP_X_FORWARDED_FOR"]) )    {
	$ip=$_SERVER["HTTP_X_FORWARDED_FOR"] . ' ';
} else if ( isset($_SERVER["HTTP_CLIENT_IP"]) )    {
	$ip=$_SERVER["HTTP_CLIENT_IP"] . ' ';
}
$IpAddr = $ip;
?>

The rest of the script containing javascript code to customize text color, background color, font size and text format.

To display these badges on your website, make Inline JavaScript is as follows

<script language="JavaScript">
v_ip_BackColor = "blue";
v_ip_ForeColor = "white";
v_ip_FontPix = "16";
v_ip_DisplayFormat = "You are visiting from:<br>IP Address: %%IP%%";
v_ip_DisplayOnPage = "yes";
</script>
<script language="JavaScript" src="http://www.example.com/ipaddr.php"></script>
  • v_ip_BackColor background color
  • v_ip_ForeColor foreground color
  • v_ip_FontPix font size
  • v_ip_DisplayFormat texts that can be customized
