getting url inputs

[xlordt]

Im tring to create a script that will help others learn unix/linux.. but i have a problem.. im tring to retrive data.. from the user when they input something like.. ls /blah .. but.. the / will turn into hex charactor's .. i tried using urldecode() and
rawurldecode() but it does not decode the url.. Does anyone have any other idea on how i can get the users input after the urlencoded char's?

i guess you have a form with an input field on a page and your useres should enter their "ls /whatever" stuff there?

anyway... you should submit your form-data by post and not by get. this way the problem shouldn't occur.

so if i was to use post instead of get then.. how would i get the users input.. after ls cause once they type in a space it will encode to something like.. %2F how do i get the input right after the space using the form thanx for your reply

I think you have to be more specific. Is it on the server or on the client you experience trouble? Maybe it´s on both. I can´t help you with the information you have attached.

As I understand it you have a HTML form and an input (type="text") element. Or is it a textarea? When a user types in the text and types a space the text is encoded to %2F (or whatever) or does this happen when the user have submitted the form?

Yes i am sorry for my lack of communication in my post.. but yes you are correct. this happends only when the user hits enter (as in submit) then me using the get method the url will encode.. for example

ls /home/xlordt

now.. in the example above the space will turn in to + and the / will encode its self in the url to %2F that is the encoded value that i get once a user enters a backslash .. so see what im tring to do is get the command witch its.. ls and the directory that they want to go to (or view)

just in case here is my script

$dir_name = array('bin'=>array('ls'=>$unix,
                               'cd'=>$unix,
			      'pwd'=>$unix, 'rm'=>$unix, 'dir'),
                  'home'=>array(
                  'xlordt'=>array('test'),
		          'users'=>array('boo'),
		          'test',),
		          'etc'=>array('passwd','shadow'),);

$shell = "[" .$_USER['username']. "@colledgeunix/$dir_name[$unix]]$ ".$unix;
$pwd = $dir_name['unix'];


$unix = str_replace($dir_name['unix'], $dir_name[$key]['unix'], $unix); 
if(array_key_exists($unix, $dir_name["bin"])){

  switch($_POST['unix']){

     case 'ls':

      ksort($dir_name);
      $unix = "";
      foreach(array_keys($dir_name) as $k){
      $unix .= "$k ";
   }
 break;

 case 'cd':

	   ksort($dir_name[$unix][$pwd]);
       $unix = "";
       foreach(array_keys($dir_name['unix']) as $k){
       $unix .= "$k " ;
}

 break;
     default:
     $unix = "Command not found";
}
 }

 echo "<center><form method=\"POST\" action=\"$PHP_SELF\">
        <table width=\"100%\" height=\"100%\" bgcolor=\"#000000\" >
         <tr ><td>
          <font color=\"FFFFFF\">$shell&nbsp;<br>$unix</td></tr>
           </td></tr><tr><td><br><br><br><Br><br><br><Br><br>
           <br><br><br><br><br>
        CMD&nbsp;&nbsp;
       <input type=\"text\" name=\"unix\" size=\"95\" >
          </td></tr>
            <tr><td>
	<inpyt type=\"hidden\" name=\"pwd\" value=\"$dir_name\">
               </td></tr>
        </table></form>
        ";

Hmm anyone 🙁 i been working on this for days and i still cant get it to work with its directories... (SUX NOT TO BE KNOWLEDGABLE)😕

Hope you are familiar with the $POST and $GET varibles. If not then you should read the PHP manual again :-) Using $_POST[unix] maybe would solve your problem.

heh? ya i am familiar with POST and GET but how do i get another argument from the users input like.. for example lsl<space does not count>/home

i am using POST and i was using get.. anyways... do you have an example

[trexx]

take a look a this:

<?php
// get command and arguments
$_POST['command'] = trim($_POST['command']);
$tmp = explode( ' ', $_POST['command'] );
$command = strtolower( $tmp[0] );
$args = Array();
if( count($tmp) > 0 )
{
	$args = array_slice( $tmp, 1 );	
}

// do whatever you want with the command
switch( $command )
{
	case 'ls';
		echo 'ls used<br>';
	break;
}
?>
<html>
<body>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
	cmd: <input type="text" name="command" >
</form>
command: <?=$command?><br>
arguments: <?=implode(' ',$args)?>
</body>
