Create a new module for International Checkout payment module

[icecold]

Well, if you're not *on* the shopping cart page when you're running your particular code, then that whole array won't even be available to you, so you won't be able to use the variables at all.

But, assuming you were on that page, if you think about it, the foreach is used to render each line in the shopping cart. So, unless you're already doing something as part of looping thru the array within the template, you'll have to loop thru it again if you want it to handle *all* products in the cart.

Yes, I thought so, I have to loop through all the products ...

Thanks for the tips ...

I just made this function within the Class

function process_button() {
      global $HTTP_SERVER_VARS, $product, $customer_id;

foreach ($productArray as $product) {
    
      $process_button_string = zen_draw_hidden_field('ItemQuantity',$product['quantityField'] . 
                               zen_draw_hidden_field('ItemImage', $product['productsImage']) . 
                               zen_draw_hidden_field('ItemDescription', $product['productsName']) . 
                               zen_draw_hidden_field('ItemPrice', $product['productsPrice']);

      $process_button_string .= zen_draw_hidden_field(zen_session_name(), zen_session_id());
      return $process_button_string;
    }
} 

Hope it works

I don't know why you're referencing $HTTP_SERVER_VARS, both because you're not using them in that function, and also because they're obsolete in PHP 5.3, replaced by $_SERVER instead. But, since you're not using it, you don't need it listed. Also, you're not using $customer_id, so don't need that either.
Also, since $productArray is never set inside that function, you'll just get a blank string for your output ... actually likely a null string since the variable never gets set.
I've no idea why you're doing this with process_button() ... I guess you're using that to send the data someplace along with the customer, instead of doing it all via CURL as discussed before.

I will do, and I am not really familiar with PHP5 syntax so thanks for the tip ...

I am really trying to understand the logic behind the payment module Class, so I am just experimenting and testing different approaches.

Most of my functions are return false; since the only thing I need to do is to pass the info ...

Process_button uses $HTTP_SERVER because to pass the data to curl_setopt($ch, CURLOPT_POSTFIELDS, I pass a string of characters gathered in process_button(), and then
concatened in the next function, what it does is to assign each value to an element of the array ...

Here is my curl connection:

class ic {
    var $code, $title, $description, $enabled;


    function https_send($params)
    {

$test_mode=0;
    
        $ch = curl_init(); 
        curl_setopt($ch, CURLOPT_URL,"https://www.internationalcheckout.com/cart.php"); 

// Seed cURL connection options
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_FAILONERROR, 1); 
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
        curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); 
        curl_setopt($ch, CURLOPT_POST, 1); 
// Create iData packet from individual fields...
$idata=implode(",",$params["iData"]);

// Compose and send POST message
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'Company=' . $params["iccompany"] . '&iData=' . $idata); 
        $result=curl_exec ($ch); 
        curl_close ($ch); 

        return $result; 

and below are the 2 functions that collect data to be transmitted by POSTFIELDS:

//Prepare the data from the cart to be transmited using curl

    function process_button() {
      global $HTTP_SERVER_VARS, $product, $customer_id;

foreach ($productArray as $product) {
    
      $process_button_string = zen_draw_hidden_field('ItemQuantity',$product['quantityField'] . 
                               zen_draw_hidden_field('ItemImage', $product['productsImage']) . 
                               zen_draw_hidden_field('ItemDescription', $product['productsName']) . 
                               zen_draw_hidden_field('ItemPrice', $product['productsPrice']);

      $process_button_string .= zen_draw_hidden_field(zen_session_name(), zen_session_id());
      return $process_button_string;
    }

}
// !Functions to execute before processing the order
    function before_process() {
      global $HTTP_POST_VARS;

      $params['iccompany']= MODULE_PAYMENT_IC_COMPANY;
      $params['ItemQuantity'] = $HTTP_POST_VARS['ItemQuantity'];
      $params['ItemImage'] = $HTTP_POST_VARS['ItemImage'];
      $params['ItemDescription'] = $HTTP_POST_VARS['ItemDescription'];
      $params['ItemPrice'] = $HTTP_POST_VARS['ItemPrice'];
      
      $params['iccompany'] = urlencode($params['iccompany']);
      
      $params['iData'][0] = urlencode($params['ItemQuantity']);
      $params['iData'][1] = urlencode($params['ItemImage']);  
      $params['iData'][2] = urlencode($params['ItemDescription']);
      $params['iData'][3] = urlencode($params['ItemPrice']); 
      
      
         // remove params with empty values
      foreach ($params as $key => $value) {
        if (!$value) {
          unset($params[$key]);
        }
      } 

What I'm trying to figure out is if how can made another loop in before_process() so it gathers all the values from process_button.

I will make the change to $_SERVER, as you suggested, but if the array $products, gets it's content in the shopping cart, why will it pass empty fields to my class? Do I need to do another db query so ProductsArray[] has data again?

You don't need it, because you're not using it ... at least, not in that function.

but if the array $products, gets it's content in the shopping cart, why will it pass empty fields to my class?

First, because payment modules are not activated on the shopping cart page, there's no way the $productsArray will have any data in it anyway.
Second, every function starts clean, and knows nothing about any other variables outside itself. That's just how PHP has always worked. Each function is its own scope. The only way to get around that is to pass parameters to it or to global certain variables, and using global is an older convention only applicable to procedural code, whereas PHP is headed towards object-oriented code instead.

Do I need to do another db query so ProductsArray[] has data again?

Yes, as I said, unless you're ON the shopping cart page when the payment module is instantiated and called, none of the shopping cart data is available to you anyway.
If you want to mimic similar behavior you'll have to copy and duplicate the code to do that.

You're not merely writing another payment module here. It's more like you're re-architecting a whole new checkout.

I thought because we were in the same session some vars might had content ... (that was just in theory).

ok, so the cart data is stored in tables? So I can query them and retrieve it? ...

Yes, more like it, as this system overrides all the functions and takes only raw data from the cart. So in PHP OOP there is no way to 'store' an array and reuse its contents, not even in a SESSION(I am really not familiar with PHP OOP)?

Well, yes there is, but Zen Cart 1.x isn't OOP structured.

[icecold]

Well, yes there is, but Zen Cart 1.x isn't OOP structured.

ok how about the cart history? I have seen the cart contents get stored there intact, what if I try to retrieve the data from those tables?

for ($i=0, $n=sizeof($products); $i<$n; $i++) {
  if (($i/2) == floor($i/2)) {

$productsImage = (IMAGE_SHOPPING_CART_STATUS == 1 ? zen_image(DIR_WS_IMAGES . $products[$i]['image'], $products[$i]['name'], IMAGE_SHOPPING_CART_WIDTH, IMAGE_SHOPPING_CART_HEIGHT) : '');
$quantityField = zen_draw_input_field('cart_quantity[]', $products[$i]['quantity'], 'size="4"');
 $productsPrice = $currencies->display_price($products[$i]['final_price'], zen_get_tax_rate($products[$i]['tax_class_id']), $products[$i]['quantity']) . ($products[$i]['onetime_charges'] != 0 ? '<br />' . $currencies->display_price($products[$i]['onetime_charges'], zen_get_tax_rate($products[$i]['tax_class_id']), 1) : '');
  $productsPriceEach = $currencies->display_price($products[$i]['final_price'], zen_get_tax_rate($products[$i]['tax_class_id']), 1) . ($products[$i]['onetime_charges'] != 0 ? '<br />' . $currencies->display_price($products[$i]['onetime_charges'], zen_get_tax_rate($products[$i]['tax_class_id']), 1) : '');

// Create a smaller Array to hold just the data above

  $productArray[$i] = array( 'productsImage'=>$productsImage,
                                            'productsName'=>$productsName,
                                            'quantityField'=>$quantityField,
                                             'productsPrice'=>$productsPrice,
                                  'productsPriceEach'=>$productsPriceEach,
                            'rowClass'=>$rowClass,
                      
                            'id'=>$products[$i]['id']);
} // end FOR loop 

I borrowed some of the code from header.php my question is will this work, in my class or will it have a conflict problem?

Just created a new array with the same name and populated it with the same data.

So later I can use it within my class ...

I think I forgot to add >>>

$products = $cart->get_products();

at the top

I wanted to know if there are any specific requirements to be met prior to installing and testing a module, as I want to echo some variables, and array contents, but as the data is retrieved from a live cart, in a live session, I wanted to know in advance if that is possible or I have to install this testing module first, to avoid conflicts.
