通过foreach循环显示会话数组值

我想使用foreach循环显示会话中的所有存储数据。我无法表现出来。任何人都可以给我一个关于如何显示储值的想法。我需要显示每个添加产品的PRODUCT ID和INFO。下面是代码 - ？`通过foreach循环显示会话数组值

<?php 
session_start(); 
/* 
TEMPLATE NAME: Cart Page 
*/

<?php 
    $git_product_id = $_POST['git_product_id']; 
    $git_required = $_POST['git_required']; 
    $git_action = $_POST['git_action']; 

    if (isset($git_product_id)){ 

     switch($git_action){ 

      case "add" : 
       // adding product 
        // checking first if the product is already added 
        if (isset($_SESSION['cart'][$git_product_id])){ 
         echo "You have already added this product";      
        } else { 
         // I AM NOT SURE IF THIS CODING IS OKAY. PLEASE CHECK THIS 
         if (!isset($_SESSION['cart'])) { 
          $_SESSION['cart'] = array(); 
         } 
         $_SESSION['cart'][$git_product_id] = array('product_id' => $git_product_id, 'info' => $git_required); 

        } 
      break; 

      case "remove": 
       // removing product 
       unset($_SESSION['cart'][$git_product_id]); 
      break; 

      case "empty" : 
       // empty cart 
       unset($_SESSION['cart']); 
      break;    

     } 
    } 
?> 

<?php 

    if ($_SESSION['cart'] != ""): 
     foreach($_SESSION['cart'] as $product => $key) : ?> 
     <tr> 
      <td> 
       <?php // I WANT TO SHOW HERE EACH PRODUCT ID and RESPECTIVE REQUIRED INFO ?> 
       <?php // BUT I DON'T KNOW HOW TO DO IT ?> 
      </td> 

      <td> 
       <form action="" method="post"> 
        <input type="hidden" name="git_product_id" value="<?php echo $product; ?>" /> 
        <input type="hidden" name="git_required" value="<?php echo $qty; ?>" /> 
        <input type="hidden" name="git_action" value="remove" /> 
        <input type="submit" value="Remove" /> 
       </form> 
      </td> 

     <?php endforeach; ?> 
    <?php endif; ?> 

    <form action="" method="POST"> 
     <input type="hidden" name="git_product_id" value="<?php echo $product; ?>" /> 
     <input type="hidden" name="git_required" value="<?php echo $qty; ?>" /> 
     <input type="hidden" name="git_action" value="empty" /> 
     <input type="submit" value="empty" /> 
    </form>

做'的var_dump（$ _ SESSION）'看什么没什么。 – 2013-02-18 18:08:00

@MarcB：你能想出更多的细节吗？我会受益匪浅。 var_dump（$ _ SESSION）后我会做什么？ – Nur 2013-02-18 18:10:09

检查被甩的东西，看看你是否真的有任何购物车的数据。 – 2013-02-18 18:10:33

此代码总是对我的作品，这不完全是你问什么...但它包含了一个for循环。

在以下示例中：
- $ sys [session_allowed]是白名单阵列，如果您没有，可以跳过/删除它。
- 会话数据是可用的$ SESS [foo1]，$ SESS [foo2的]等

// create session 
session_cache_limiter('private, must-revalidate, post-check=0, pre-check=0'); 
session_start(); 

// load values, and encrypt 
$enc_data = explode(";", session_encode()); 
$sess_name = array(); $sess_data = array(); 
for ($i=0;$i<count($enc_data)-1;$i++) 
    { 
    $sess_get = explode("|", $enc_data[$i]); 
    if (substr($sess_get[1], 0, 2)=="s:") 
    { 
    $tmp = str_replace("\"", "", strstr($sess_get[1], "\"")); 
    if (strlen($tmp)!=0 && in_array($sess_get[0], $sys[session_allowed])) 
     { $sess_data[$i] = $tmp; $sess_name[$i] = $sess_get[0]; } 
    } 
    else 
    { 
    $tmp = substr($sess_get[1], 2); 
    if (strlen($tmp)!=0 && in_array($sess_get[0], $sys[session_allowed])) 
     { $sess_data[$i] = $tmp; $sess_name[$i] = $sess_get[0]; } 
    } 
    } 
if (count($sess_name)>=1) { $sess = array_combine($sess_name, $sess_data); } 
else { $sess = array(); } 

// now you can access SESSION data by $sess[blabla1], $sess[blabla2] 

// to add to session, use function (max 3 add actions): 
function session_add($act1="", $act2="", $act3="") 
    { 
    global $sess, $_SESSION; 
    if (strlen($act1)!=0) { $loc = strpos($act1, "="); $act_a = substr($act1, 0, $loc); $act_b = substr($act1, $loc+1); $_SESSION[$act_a] = $act_b; $sess[$act_a] = $act_b; } 
    if (strlen($act2)!=0) { $loc = strpos($act2, "="); $act_a = substr($act2, 0, $loc); $act_b = substr($act2, $loc+1); $_SESSION[$act_a] = $act_b; $sess[$act_a] = $act_b; } 
    if (strlen($act3)!=0) { $loc = strpos($act3, "="); $act_a = substr($act3, 0, $loc); $act_b = substr($act3, $loc+1); $_SESSION[$act_a] = $act_b; $sess[$act_a] = $act_b; } 
    } 

// to remove from session, use function (max 3 delete actions): 
function session_rem($act1="", $act2="", $act3="") 
    { 
    global $sess, $_SESSION; 
    if (strlen($act1)!=0) { $_SESSION[$act1] = ""; unset($sess[$act1]); } 
    if (strlen($act2)!=0) { $_SESSION[$act2] = ""; unset($sess[$act2]); } 
    if (strlen($act3)!=0) { $_SESSION[$act3] = ""; unset($sess[$act3]); } 
    }
