修改會話變量（購物車）

Question

會話產品

$product = array(array('name'=>$resname, 'code'=>$product_code, 'qty'=>$product_qty, 'price'=>$resprice, 'sizes'=>$sizes ,'colourcode'=>$colourcode , 'availability'=>$availability)); 
$_SESSION["products"] = $product; 

    name="product1"; 
    code="123"; 
    ... 
    availability=1; 

現在我想用每個僅環

foreach ($_SESSION["products"] as $cart_itm){ 
$cart_itm["code"]; 
$cart_itm["availability"]; 
//code to modify availability for current product 
}

修改可用性針對特定產品的會話是你嗎正在找？

<?php 
    session_start(); 
    $product = array(array('name'=>'resname', 'code'=>'product_code', 'qty'=>'product_qty', 'price'=>'resprice', 'sizes'=>'sizes' ,'colourcode'=>'colourcode' , 'availability'=>'availability')); 
    $newProduct=$product;// new step 
    $_SESSION["products"] = $newProduct; 


    foreach ($_SESSION["products"] as $cart_itm){ 
    $newProduct[0]["availability"]='modifiedavailability'; 
    } 

    //or To all Keys 

    // foreach ($_SESSION["products"] as $cart_itm => $value){ 
    //$cart_itm["code"]; 
    //$newProduct[$cart_itm]["availability"]='modavaila'; 
    //} 
    $_SESSION["products"] = $newProduct; 
    print_r($_SESSION["products"]); 
?>
