How to force a pop up page?

[landysaccount]

Hello everyone.

I currently have a small wisp with NoCatSplash on the router. When a client tries to access a page they get a splash page where they have to press a button to authenticate and pass to the internet. Is an open/public splash page, no real user authentication with username and password. This happens every six hours. Once the client presses the button they get redirected to the page it requested. Here, I record the ip address, time they "logged in". Now, what I need is to be able to have a pop up page along with the requested page to those clients that haven't make their payment on time.

I tried doing this on the actual splash page but, is written in perl and I can't embed php into a perl script. Any idea on how I can add that little feature to the splash page or a way on how to just force a pop up page every certain time during the client's browsing to remind client of the payment?

Thanks in advanced for your help.

PHP doesn't do pop up windows. Neither does Perl. 🙂

You need JavaScript.

window.open(url, windowname);

This is what splash.php looks like:

<form method="POST" action="$action">
<input type="hidden" name="redirect" value="http://192.168.2.1/splash/check_status.php?requestedPage=$redirect">
<input type="hidden" name="requestedPage" value="$redirect">
<input type="hidden" name="accept_terms" value="yes">
<input type="hidden" name="mode_login">
<input type="submit" class="button" value="Entrar a la Red...">
</form>

The action script is a perl script that is ran by NoCat to allow access to the user. What I do here is that I force that script to check_status.php.

Here's what the check_status.php looks like:
if ( $SERVER["HTTP_CLIENT_IP"] ) $ip = $SERVER["HTTP_CLIENT_IP"];
else if( $SERVER["HTTP_X_FORWARDED_FOR"] ) $ip = $SERVER["HTTP_X_FORWARDED_FOR"];
else if( $SERVER["REMOTE_ADDR"] ) $ip = $SERVER["REMOTE_ADDR"];
else $ip = "UNKNOWN";

$mac = `sudo arp -i eth1 $ip | grep : | awk '{print $3}'`;

//record visit
$query = "insert into network_access ( ip, mac, timevisit ) values ( '$ip', '$mac', " . time() . " )";

$result = dba_connect( $query, 1 ) or
          die( "Query: '$query', failed with error message: -- " . mysql_error() . " --" );
// end visit record

// check if is a company address
$query = "select * from private_ip where priv_ip_address='$ip'";
$result = dba_connect( $query, 1 ) or
                  die( "Query: '$query', failed with error message: -- " . mysql_error() . " --" );
// immediately send private ip's to the requested page
if( mysql_num_rows( $result ) >= 1 ){
  $location = "Location: " . $_REQUEST['requestedPage'];
  header("$location");
  exit;
}

$query = "select dhcp_cust_id as id from dhcp where dhcp_ip='$ip'";
$result = dba_connect( $query, 1 ) or
                  die( "Query: '$query', failed with error message: -- " . mysql_error() . " --" );

// if there isn't any match here then the user is not registered.
  if( mysql_num_rows( $result ) == 0 ){
  $location = "Location: ./notregistered_mesg.php";
  header("$location");
  exit;
}
$row = mysql_fetch_array( $result );

$query = "select customer_status as status from customer where customer_id=" . $row["id"];
$result = dba_connect( $query, 1 ) or
                  die( "Query: '$query', failed with error message: -- " . mysql_error() . " --" );

$row = mysql_fetch_array( $result );

if( $row["status"] == "SUSPENDIDO" ){
  header("Location: ./suspended_message.php");
  exit;
}
else
{
  $location = "Location: " . $_REQUEST['requestedPage'];
  header("$location");
}

==============================

So, what I would like to do is run another script before the header that would check if the user has a pending balance to remind them with a pop up window and still let them continue with their requested page..

[Kudose]

I don't see where you are doing that check. Also, you won't be able to use header if you send content (such as a pop-up) to the browser. You'd need your pop-up to either redirect or close itself and refresh the parent window.

I actually tried adding the code below on the splash.php page but, somehow is not getting parsed.

if ( $SERVER["HTTP_CLIENT_IP"] ) $ip = $SERVER["HTTP_CLIENT_IP"];
else if( $SERVER["HTTP_X_FORWARDED_FOR"] ) $ip = $SERVER["HTTP_X_FORWARDED_FOR"];
else if( $SERVER["REMOTE_ADDR"] ) $ip = $SERVER["REMOTE_ADDR"];
else $ip = "UNKNOWN";
//echo $ip;
// check if is a company address
$query = "select * from private_ip where priv_ip_address='$ip'";
$result = dba_connect( $query, 1 ) or
die( "Query: '$query', failed with error message: -- " . mysql_error() . " --" );
// immediately send private ip's to the requested page
if( mysql_num_rows( $result ) >= 1 ){
$remind_payment = 'false';
}
else{
$query = "select dhcp_cust_id as id from dhcp where dhcp_ip='$ip'";
$dhcp_result = dba_connect( $query, 1 ) or
die( "Query: '$query', failed with error message: -- " . mysql_error() . " --" );

  if( mysql_num_rows( $dhcp_result ) == 0 ){
    $not_registered = 'true';
    $remind_payment = 'false';
  }// not registered
  else{
    $row = mysql_fetch_array( $dhcp_result );

    // check if there is a balance
    $bal_query = "select bal_amount as bal from balance where bal_cust_id=" . $row['id'];
    $bal_result = dba_connect( $bal_query, 1 ) or 
          die( "Query: '$bal_query', failed with error message: -- " . mysql_error() . " --" );
    $row = mysql_fetch_array( $bal_result );
   // echo "balance: " . $row['bal'];
    if( $row['bal'] > 0 ){ $remind_payment = 'true';} else{ $remind_payment = 'false'; }
  }
}

Later in the body tag I added this:

<body bgcolor="#5aa91f" text="#000000" onLoad="<? if( $remind_payment == 'true' ) echo "newWindow('./payreminder.php')"; ?>">

[Kudose]

Are you sure $remind_payment is getting a value? I assume you have short_tags enabled since you are using <?, but if not, that is a problem. You should be using <?php for portability.

Also, you should assign a boolean value to $remind_payment instead of the textual version. Then you can just use:

if($remind_payment){ // do something }

[landysaccount]

I do have short tags enabled. My problem with the script is that is NOT getting parsed. I believe is because is that splash.php is used by NoCat that is written in perl. But, my confusion is that I try to execute the script when the splash page is called and as a result should be parsed normally.

Don't know where I'm failing.

[landysaccount]

I was further testing and noticed when I explicitly enter the splash.php location in the browser address bar everything gets parsed correctly but, if I enter another address before authentication for ie: www.google.com, NoCat intercepts and redirects to the splash page: http://192.168.2.1/?redirect=http://www.google.com/ . When I check the page source code is not getting parsed. All the php script is visible:

<body onLoad="<?php if( == 'true' ) echo 'newWindow('./payreminder.php');'; ?>">

I don't know what's going on but, this has given me a lot of problems. Any ideas?

[Kudose]

After re-reading your first post, you are running everything from your router. I doubt it has PHP installed, so it won't be able to parse the PHP file. Where is your PHP engine located?

edit

I searched the internets and found some people running PHP on their routers (I will have to check into this 🙂).

Can you tell your handler to pass .php files to PHP?

[landysaccount]

Actually I'm running php on the router. Since this is where I can block or permit traffic. I'm doing most of the stuff with php: I write a bash script with it, an iptables script, and other stuff as well.
