num_cart_items返回空

Question

我正在使用IPN模擬器將數據發佈到我的IPN處理程序。一切都很好，除了這個。

$num_cart_items = $_POST['num_cart_items']; 

$tuotteet = array(); 
for($i = 1; $i <= $num_cart_items; $i++) { 
    $tuotteet[] = array('nimi'=>$_POST['item_name' . $i], 'maara'=>$_POST['quantity' . $i]); 
} 
$products = implode(" ", array_map(function ($entry) { return $entry['maara'].'x '.$entry['nimi'].'<br />'; }, $tuotteet)); 

當我嘗試將$ products存儲到數據庫時，我得到空值。我也嘗試保存$ num_cart_items，並顯示爲空。

你在這裏。這將加載$ cart_items與所有單個項目，您可以輕鬆地循環或序列化並直接保存。

// Cart Items 
$num_cart_items = isset($_POST['num_cart_items']) ? $_POST['num_cart_items'] : ''; 

$i = 1; 
$cart_items = array(); 
while(isset($_POST['item_number' . $i])) 
{ 
    $item_number = isset($_POST['item_number' . $i]) ? $_POST['item_number' . $i] : ''; 
    $item_name = isset($_POST['item_name' . $i]) ? $_POST['item_name' . $i] : ''; 
    $quantity = isset($_POST['quantity' . $i]) ? $_POST['quantity' . $i] : ''; 
    $mc_gross = isset($_POST['mc_gross_' . $i]) ? $_POST['mc_gross_' . $i] : 0; 
    $mc_handling = isset($_POST['mc_handling' . $i]) ? $_POST['mc_handling' . $i] : 0; 
    $mc_shipping = isset($_POST['mc_shipping' . $i]) ? $_POST['mc_shipping' . $i] : 0; 
    $custom = isset($_POST['custom' . $i]) ? $_POST['custom' . $i] : ''; 
    $option_name1 = isset($_POST['option_name1_' . $i]) ? $_POST['option_name1_' . $i] : ''; 
    $option_selection1 = isset($_POST['option_selection1_' . $i]) ? $_POST['option_selection1_' . $i] : ''; 
    $option_name2 = isset($_POST['option_name2_' . $i]) ? $_POST['option_name2_' . $i] : ''; 
    $option_selection2 = isset($_POST['option_selection2_' . $i]) ? $_POST['option_selection2_' . $i] : ''; 
    $option_name3 = isset($_POST['option_name3_' . $i]) ? $_POST['option_name3_' . $i] : ''; 
    $option_selection3 = isset($_POST['option_selection3_' . $i]) ? $_POST['option_selection3_' . $i] : ''; 
    $option_name4 = isset($_POST['option_name4_' . $i]) ? $_POST['option_name4_' . $i] : ''; 
    $option_selection4 = isset($_POST['option_selection4_' . $i]) ? $_POST['option_selection4_' . $i] : ''; 
    $option_name5 = isset($_POST['option_name5_' . $i]) ? $_POST['option_name5_' . $i] : ''; 
    $option_selection5 = isset($_POST['option_selection5_' . $i]) ? $_POST['option_selection5_' . $i] : ''; 
    $option_name6 = isset($_POST['option_name6_' . $i]) ? $_POST['option_name6_' . $i] : ''; 
    $option_selection6 = isset($_POST['option_selection6_' . $i]) ? $_POST['option_selection6_' . $i] : ''; 
    $option_name7 = isset($_POST['option_name7_' . $i]) ? $_POST['option_name7_' . $i] : ''; 
    $option_selection7 = isset($_POST['option_selection7_' . $i]) ? $_POST['option_selection7_' . $i] : ''; 
    $option_name8 = isset($_POST['option_name8_' . $i]) ? $_POST['option_name8_' . $i] : ''; 
    $option_selection8 = isset($_POST['option_selection8_' . $i]) ? $_POST['option_selection8_' . $i] : ''; 
    $option_name9 = isset($_POST['option_name9_' . $i]) ? $_POST['option_name9_' . $i] : ''; 
    $option_selection9 = isset($_POST['option_selection9_' . $i]) ? $_POST['option_selection9_' . $i] : ''; 

    $btn_id = isset($_POST['btn_id' . $i]) ? $_POST['btn_id' . $i] : ''; 

    $current_item = array( 
          'item_number' => $item_number, 
          'item_name' => $item_name, 
          'quantity' => $quantity, 
          'mc_gross' => $mc_gross, 
          'mc_handling' => $mc_handling, 
          'mc_shipping' => $mc_shipping, 
          'custom' => $custom, 
          'option_name1' => $option_name1, 
          'option_selection1' => $option_selection1, 
          'option_name2' => $option_name2, 
          'option_selection2' => $option_selection2, 
          'option_name3' => $option_name3, 
          'option_selection3' => $option_selection3, 
          'option_name4' => $option_name4, 
          'option_selection4' => $option_selection4, 
          'option_name5' => $option_name5, 
          'option_selection5' => $option_selection5, 
          'option_name6' => $option_name6, 
          'option_selection6' => $option_selection6, 
          'option_name7' => $option_name7, 
          'option_selection7' => $option_selection7,

          'option_selection9' => $option_selection9, 
          'btn_id' => $btn_id 
         ); 

    array_push($cart_items, $current_item); 
    $i++; 
}
