Question

我在while循环中有一些php变量，它们根据产品ID从表中的列收集数据，但结果为＆＃34; care0，care3，care5＆＃34;仅响应添加的第一个ID - 对于所提及的变量，后续产品ID没有累积添加。

<?php
$con = mysqli_connect("localhost","user","password","database");
global $con;
$ip = getIp();
$sel_price = "select * from products where ip_address='$ip'";
$run_price = mysqli_query($con, $sel_price);
while ($p_price=mysqli_fetch_assoc($run_price)){
    $pro_id = $p_price['product_id'];
    $pro_price = "select * from products where product_id='$pro_id'";
    $run_pro_price = mysqli_query($con, $pro_price);
    while ($pp_price = mysqli_fetch_assoc($run_pro_price)){
        $product_id = $pp_price['product_id'];
        $product_type = $pp_price['product_type'];
        $product_category = $pp_price['product_category'];
        $product_brand = $pp_price['product_brand'];
        $product_model = $pp_price['product_model'];
        $product_price = array($pp_price['product_price']);
        $product_install = $pp_price['product_install'];
        $product_delivery = '20.00';
        $product_recycle = '15.00';
        //Problem Starts Here
        $care0 = '0.00';
        $care3 = $pp_price['care3'];
        $care5 = $pp_price['care5'];
        //Problem ends here
        $product_title = $pp_price['product_title'];
        $product_image = $pp_price['product_imagelist'];
        $single_price = $pp_price['product_price'];
        $values = array_sum($product_price);
        $subtotal += $values;
        $fulltotal = $subtotal+$product_delivery+$product_install+$product_recycle;
?>

变量的结果在3个单选按钮的值中回显，并在提交表单时更新，然后金额在相邻的div中回显。

<html>
<div class="bask-tot3"><p class="nobr"><span class="grey-lite">Extended Warranty&nbsp;&nbsp;<span class="blue-link"><a href="warranty" title="find out about extended warranties...">find out more</a></span><br/><br/></span></p>
<p class="nobr"><input type="radio" name="care" value="<?php echo $care0; ?>" checked="checked" />&nbsp;No thanks</p>
<p class="nobr"><input type="radio" name="care" value="<?php echo $care3; ?>" />&nbsp;3 years</p>
<p class="nobr"><input type="radio" name="care" value="<?php echo $care5; ?>" />&nbsp;5 years</p>
</div>
<div class="bask-tot4"><p><?php echo £ . $_POST["care"]; ?></p></div>
</html>

如您所见，care3和care5来自表数据，但care0不是。

多个产品价格的计算器$ product_price工作正常，因为它在一个数组中，但多个护理包价格的计算器只响应添加的第一个项目。我想我错过了一个foreach语句，或者需要将这三个变量放到一个数组中，但我对如何实现它感到茫然。
