LinuxQuestions.org - Adding users with PHP (pass php variables to Expect script)

Hi there, I could't find an answer already here so I've made a post, forgive me if the answer is here but I couldnt find it.

Ok so here goes, I have a php page that takes a username in( from textbox), i want to send that username thru to an Expect script

The expect script will log in as root, add the user, do whatever else i decide, then switch out of root.

heres what I've come up with so far...

The first page, with the form that takes in the username

Code:

<html>

<head>

<title>Assignment</title>

</head>



<body>



<h1>The worst User management ever...</h1><p>

<form name="userdata" action="process.php" method="post">

Username:<input name="username" type="text"><br>

Password:<input name="password" type="text"><br>

Message:<br>



<br>

<input type="submit">

</form>

</body>

</html>

The username gets passed into this php file, and echoed back on the screen for confirmation, this part works fine

Code:

<html>

<body>



<?php

$username = $_POST['username'];

$password = $_POST['password'];

//$username = "jack";

//$password = "1234";



//error_reporting(E_ALL);



//Run some linux script to actually ADD the user, only passing 1 var till //i can work it out



exec("/opt/lampp/htdocs/wse/adding.exp". $username);



//print($bashreturn);

echo "Your Username is ". $username .".<br>";

echo "Your Password ir ". $password .".<br>";





?>

<p>

<a href="index.html">Go back and try again</a>

</body>

</html>

the username should be sent here, then added to the linux box, but this doesn't work

Code:

#! /usr/bin/expect -f



username=$1



set force_conservative 0



spawn su

match_max 100000

send -- "password\r"

send -- "useradd username\r"

send -- "exit\r"

expect eof

I think that the initial data is being passed to the second php file becuase it is echoed back on screen, but as for being sent to the exp script I have no idea

Can someone please help me solve this problem, I'm having little luck finding tutorials/solutions on the internet

Thank you for your time
