set variable(s) from checkboxes - display multiple results

[Nucleus]

I am using the below to sent ssh commands through a web interface. Below is an example to get the hostname of a Linux computer.

 

I need to change this form, from a dropdown menu, to checkboxes. I know how to do this in html, but I don't know how to tell php to handle it. Reason is, what if multiple checkboxes are selected? how would  target="main" display results from multiple computers?

 

index.html

 <form action="phpseclib/hostname.php" method="get" target="main">
      <select name="clients">
          <option value="SelectClient">Select Client</option>
          <option value="192.168.0.51">Client001</option>
          <option value="192.168.0.52">Client002</option>
          <option value="192.168.0.53">Client003</option>
      </select>
      <input type='submit' />
  </form>

 hostname.php

  <?php
  include('Net/SSH2.php');
  include('variables.php');
  
  $ip = $_GET['clients'];
  $ssh = new Net_SSH2($ip);
  if (!$ssh->login($user, $pass)) {exit('Login Failed');}
  echo $ssh->exec('hostname');
  ?>

How you display results is your decision. So how do you want to display it?

 

For the checkboxes, name them all clients[] and then you'll get an array of values instead of just a single value. Then use a loop to execute the command on every machine.
