PHP - Getting Methods To Work Dynamically

Hello all!

I have a page that dynamically generates checkboxes in a for() loop if $i<$product_qty, while it is generating the checkboxes the name for them is set like this $product_id_$i. In part of the next page that processes the checkboxes, I have a part that regenerates the names for those checkboxes using a for() loop again and the product_qty and then checks to see whether the checkbox is empty or not.

Everything looks right in the for() loop, yet the if() that checks whether it isset or not just ignores the ones that are set. If I make a static if with the actual name of the checkbox the if() comes back as true. I've hit a brickwall, can anyone see any errors in my code? Code is below.


// Get Old Order
$get_order = @mysql_query("SELECT * FROM orders WHERE order_id = {$_POST['order_id']}");
$order = @mysql_fetch_assoc($get_order);

// Get Old Order Items
$products = $order['products'];
//breaking products text down for display
$prod = array();

$_products = explode('|', $products);
foreach ($_products AS $p) 
$prod[] = explode(',', $p);

if(empty($prod)) {
  header("Location: tracking.php");
  die();
}

/*
// Create New Order
@mysql_query("INSERT INTO orders SET customer_id = {$order['customer_id']}, order_status = {$order['order_status']}, order_date = '{$order['order_date']}', order_date_paid = '{$order['order_date_paid']}', order_shipping = '{$order['order_shipping']}', order_shipping_fee = '{$order['order_shipping_fee']}', order_insurance = '{$order['order_insurance']}', order_insurance_fee = '{$order['order_insurance_fee']}', order_insurance_total = '{$order['order_insurance_total']}', order_grand_total = '{$order['order_grand_total']}', order_date = '{$order['order_date']}', order_filled = '{$order['order_filled']}', order_ship_date = '{$order['ship_date']}'");
$get_new_order = @mysql_query("SELECT MAX(order_id) AS order_id FROM orders");
$new_order_id = @mysql_result($get_new_order, 'order_id', 0);
*/

// Add Items to New Order & Remove Items from Old Order
$new_items = array();
foreach($prod as $p2) {
  for($i = 0; $i < $p2[0]; $i++) { 
    if(!empty($_POST[$p2[3].'_'.$i])) {
      $new_items[$p2[3]]++;
    }
  }
}

if(isset($_POST['50_4'])) {
echo "hi";
}

Well the title may seem a bit confusing, but heres an example:

Code: [Select]
<?php
class User{
   public $uid;
   public $username;
   protected $password;
   protected $email;
   public $usergroup;
   public $profile;
   

  public function __construct($id){
      // constructor code inside
  }

  public function getemail(){
      return $this->email;
  } 
   
  public function getusergroup(){
      return $this->usergroup;
  }

  public function getprofile(){
      $this->profile = new UserProfile($this->uid);
  }
}

class UserProfile(){
   protected $avatar;
   protected $bio;
   protected $gender;
   protected $favcolor;
   

  public function __construct($id){
      // constructor code inside
  }

  public function formatavatar(){
      // avatar formatting code inside
  }

  public function formatusername(){
      // format username?
  } 
}
?>

As you can see, the User class(an outer class) has a property called Profile, which can be instantiated as a UserProfile object(an inner class). The two objects have distinct functionalities, but there are times when the UserProfile object needs to access property and methods from the user object. I know its easy for outer class to access methods from inner class by using the single arrow access operator twice, but how about the other way around?

Lets say from the above example the userprofile can format the username displayed to the screen by adding a sun to the left of the username if the usergroup is admin, a moon if the usergroup is mod, and nothing if its just a member. The usergroup property is stored in the outer class, and can be accessed with this $user->getusergroup() method only. I know I can always do the hard way by passing a user object to the method's argument, but is there an easier way for the inner class UserProfile to access properties/methods for outerclass User? If so, how can I achieve that?

I don't know if this belongs here; sorry if it doesn't.

I'm using a method=get on a form as I need to pass information through a URL once the form has been submitted.
But I also need to INSERT some data from that form to multiple tables.

- How can I stop the GET from passing my other variables into the URL?
- How do I make the form submit to itself? I need to use the 'index.php?p=checkout' as this matches with a switch statement, which matches to the checkout page. The function PHP_SELF will just refresh to the index.php page, which will not have any of this checkout's page validation.

Here's my code:
Code: [Select]
<h2>Please enter your details</h2>
<h3>All fields required</h3>
<div id="checkout">

<?php

if (isset($_GET['checkout'])){
require_once ('./includes/connectvars.php');

$title = $_GET['title'];
$fname = $_GET['fname'];
$sname = $_GET['sname'];
$ctype = $_GET['ctype'];
$cnumber = md5($_GET['cnumber']);
$syear = $_GET['smonth'] . $_GET['syear'];
$fyear = $_GET['fmonth'] . $_GET['fyear'];
$service = $_GET['cardAuth'];
$amount = $_REQUEST[$total];
$msg = rand(1000,9999);
$api = 'd41d8cd98f00b204e9800998ecf8427e';
$b_house = $_GET['b_house'];
$b_postcode = $_GET['b_postcode'];
$b_city = $_GET['b_city'];
$b_country = $_GET['b_country'];
$d_house = $_GET['d_house'];
$d_postcode = $_GET['d_postcode'];
$d_city = $_GET['d_city'];
$d_country = $_GET['d_country'];

$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

$query = "INSERT INTO customer
 (cust_id, first_name, last_name) VALUES ('', '$fname', '$sname')
  ";
$query = "INSERT INTO bill 
  (cust_id) VALUES ('')
  ";
$query = "INSERT INTO deliver
  (cust_id) VALUES ('')
  ";
  
 mysqli_query($dbc, $query);
}

//.'service='.$service.'msg_id='.$msg.'num_md5='.$cnumber.'amount='.$amount.'currency=GBP'.'api_key='.$api.

what are magic methods? when do we need to use magic methods? what are the advantages of using magic methods? thanks in advanced.

hey guys im wdondering if there's a magic method which works like  

__GET()

    but allows you to put a parameter in...thank you

<?php

class test
{
      public function run()
      {
              $this->object->('string');
              // __get with parameter?
       }

       public function __get($value)
       {
              return $this->{$value}
       }
}

?>
