[SOLVED] passing and processing unknown form names and values.

[f1sh3r]

Ok, i am working on a CMS for a branch of my college that works with continuing education, non traditional students, non-credit classes. In the user table for the DB, i have user access set up in this fashion:

 

user = 00000

student worker = 01000

instructor = 00200

program developer = 00030

super admin = 00004

 

so its combinable in that a program developer can also have instructor and student worker access = 01230 or that type of deal. super admins have a page where they can delegate access to different users. below is the code that is generated when they search for the "sh". i use the preg_match function to fill in the check boxes that pertain to each persons access level.

 

i know this is probably an easy solution, but im fried. what i need to know is how to successfully mold the changes for each user into a usable format. because i dont know what the u_id is going to be, i dont know how to handle the POST data.

 

What is the best way to set up the form so that the variables/values can be tied to the user? im having a hard time explaining, sorry.

 

i would like to be able to do $id_access = "0".$student.$instructor.$developer.$super;  <-not those exact variables, but i need to be able to split up the values from multiple users using a form like the one below. if someone can help me with better names/values for my form or some type of array/foreach/while magic, i would be extremely excited.

 

hopefully someone understands my problem and took the time to read it. thanks.

i would like to be able to do $id_access = "0".$student.$instructor.$developer.$super;  <-not those exact variables, but i need to be able to split up the values from multiple users using a form like the one below. if someone can help me with better names/values for my form or some type of array/foreach/while magic, i would be extremely excited.

so you're trying to use those variable values to build those 5 digit numbers?

 

 

$access[1] = 01000; //student worker

$access[2] = 00200; //instructor

$access[3] = 00200; //program developer

$access[4] = 00200; //super admin

 

 

for ($i=0; $i<$users; $i++) //for every user

{

    $userid = $_REQUEST['you.$i']; //or get the value, 1,2,3,4 for student worker, instructor, program developer or super admin. I said you.$i because it'd go through u1, u2, u3, u4 etc etc. do as it fits.

    $id_access = $access[$userid];

}

 

hows that?

i think i have come up with a solid coding scheme. can someone tell me if this is error prone or bad coding in general? thanks.

 

<html>
<body>

<?php


if (isset($_POST[sup_admin_update])) {
  foreach ($_POST as $user => $value) {
    if (is_array($value)) {
      $admin = implode($value);
      echo "$user is $admin <br />"; // 84 is 00200, 72 is 01230
      // mysql_query ("UPDATE users SET u_access = $admin WHERE u_id = $user") or die();
    }
    else {
      $$user = $value;
      echo "$user is $value <br />"; // qupeop is sh, sup_admin_update is Change
    }
  }
}

?>
