Question

你好我只想知道如何自动增加购物车中每件商品的数量。如何自动增加购物车中的每个商品，如果两个产品1将是[0]而产品2将是[1]

这是我追求的结果......

pickuppostcode = 2000＆安培; pickupsuburb =悉尼+ CITY＆安培; deliverypostcode = 4000＆安培; deliverysuburb =布里斯班＆安培;类型[0] =纸箱＆安培;宽度[0] = 40安培;高度[0] = 35安培;深度[0] = 65安培;重量[0] = 2及项[0] = 2及式[1] = BulkyItem＆安培;宽度[1] = 50安培;高度[1] = 45安培;深度[1] = 25安培;重量[1] = 3及项[ 1] = 3及类型[2] = BulkyItem＆安培;宽度[2] = 50安培;高度[2] = 45安培;深度[2] = 25安培;重量[2] = 3及项[2] = 3

（当前）

pickuppostcode = 2000＆安培; pickupsuburb =悉尼+ CITY＆安培; deliverypostcode = 4000＆安培; deliverysuburb =布里斯班＆安培;类型[0] =纸箱＆安培;宽度[0] = 40安培;高度[0] = 35安培;深度[0] = 65安培;重量[0] = 2及项[0] = 2及式[0] = BulkyItem＆安培;宽度[0] = 50安培;高度[0] = 45安培;深度[0] = 25安培;重量[0] = 3及项[ 0] = 3

具体问题......（因为我很难编码0.需要知道如何从0开始为购物车中的每件商品自动增加。

//for each product in the cart get the following
    $max=count($_SESSION['cart']);
    for($i=0;$i<$max;$i++){ //for each product in the cart get the following
    $pid=$_SESSION['cart'][$i]['productID']; //productID
    $sql="SELECT * FROM products_dimensions WHERE productID=$pid";
    $result = mysqli_query($con, $sql) or die(mysqli_error($con)); //run the query
    while ($row = mysqli_fetch_array($result)){

    /* Dimensions */
    $width  = $row['width'];
    $height = $row['height'];
    $depth  = $row['depth'];
    $weight = $row['weight'];
    $type = $row['type'];
    $quantity=$_SESSION['cart'][$i]['qty'];

    $ego_params .= "&width[0]=$width";
    $ego_params .= "&height[0]=$height";
    $ego_params .= "&depth[0]=$depth";
    $ego_params .= "&weight[0]=$weight";
    $ego_params .= "&type[0]=$type";
    $ego_params .= "&items[0]=$quantity";
    }
    }

继承我的洞页面代码..

<?php
    session_start();
    include "../includes/connect.php";
    $calculator_url = "http://www.e-go.com.au/calculatorAPI2";
    /* from/to postcodes */
    $pickuppostcode   = 4508;
    $pickupsuburb   = urlencode('DECEPTION BAY');

    //To Destination
    $deliverypostcode   = $_POST['postCode']; 
    $deliverysuburb = urlencode(strtoupper($_POST['suburb'])); 

    $ego_params  = "?pickuppostcode=$pickuppostcode&pickupsuburb=$pickupsuburb";
    $ego_params .= "&deliverypostcode=$deliverypostcode&deliverysuburb=$deliverysuburb";

    //for each product in the cart get the following
    $max=count($_SESSION['cart']);
    for($i=0;$i<$max;$i++){ //for each product in the cart get the following
    $pid=$_SESSION['cart'][$i]['productID']; //productID
    $sql="SELECT * FROM products_dimensions WHERE productID=$pid";
    $result = mysqli_query($con, $sql) or die(mysqli_error($con)); //run the query
    while ($row = mysqli_fetch_array($result))
        {
    /* Dimensions */
    $width  = $row['width'];
    $height = $row['height'];
    $depth  = $row['depth'];
    $weight = $row['weight'];
    $type = $row['type'];
    $quantity=$_SESSION['cart'][$i]['qty']; //quantity

    $ego_params .= "&width[0]=$width";
    $ego_params .= "&height[0]=$height";
    $ego_params .= "&depth[0]=$depth";
    $ego_params .= "&weight[0]=$weight";
    $ego_params .= "&type[0]=$type";
    $ego_params .= "&items[0]=$quantity";
    }
    }
    $ego_quote  = file($calculator_url . $ego_params);

    foreach ($ego_quote as $num=>$quote) {
    $quote = trim($quote);
    $quote_field = explode("=", $quote);
    echo "Field=" . $quote_field[0] . "\tValue=" . $quote_field[1] . "\n";
    }
    $_SESSION['quote'] = $quote;
    echo $ego_params;
    //header ("location: ../pages/shoppingcart.php"); 
?>

Answer 1

为什么"&width[0]=$width"？试试"&width[$i]=$width"

PHP从0开始计数
