New Comment:
Sorry, another update. We just found the weirdest work around.
the echo the checkbox:
echo "\t<input type=\"checkbox\" name=\"1".$key."\"
value=\"".$value."\" /> ".$value
if we add the one before the $key in nam="" so that the $_POST array
starts at 10 it works fine.

Description:
------------
Reading files from a directory, stripping "." and "..". Sorting array
by values (using sort()). foreach() is used to output a checkbox for
each file (cPanel user file).
When user is checked chosen action (from the radio buttons) is to be
applied (with system command) by executing the command in action with
the appropriate username trailing.
foreach() is used to go through every $_POST value with an if() the
$keys "action" and "submit" are excluded from execution. A bash command
is put together and finally executed.
Everything works as it should, except that the array[0] is totally
ignored.
Reproduce code:
---------------
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"
/>
<title>User actions</title>
</head>
<body>
<form name="userlist" action="test.php" method="post">
<input type="radio" name="action" value="/scripts/pkgacct"
checked="checked" />Backup
<input type="radio" name="action" value="/scripts/suspendacct"
/>Suspend
<input type="radio" name="action" value="/scripts/unsuspendacct"
/>Unsuspend
<input type="radio" name="action" value="/scripts/killacct"
/>Delete
<br />
<?php
$handle = opendir("/var/cpanel/users/");
$usrarr = array(); // Array full of users
while( FALSE !== ($users = readdir($handle)) ) {
if( $users != "." && $users != ".." ) {
$usrarr[] = $users;
}
}
sort($usrarr); // sort alphabetically
foreach($usrarr as $key => $value) {
echo "\t<input type=\"checkbox\" name=\"".$key."\"
value=\"".$value."\" /> ".$value."<br />\n";
}
closedir($handle);
?>
<input name="submit" type="submit" id="submit"
value="GO">
</form>
<?php
if( isset($_POST['submit']) ) {
echo "<hr noshade=\"noshade\" />"; // output a horizontal rule for
clearance
echo "<pre>";
foreach( $_POST as $key => $value ) {
if( $key != "submit" && $key != "action" ) {
$bash = $_POST['action']." ".$value; // put together /path/command
username
echo "Processing: ".$value."<br />\n";
system($bash);
echo "Done<br />\n";
}
}
echo "<pre>";
}
?>
</body>
</html>
Expected result:
----------------
Expected result is that every $_POST key (0 through n) should be put
together with the $_POST['action'] command and a username, executed and
on to the next.
Actual result:
--------------
It works for every user, BUT the $usrarr[0] key and value.
