嘿，伙计们，我正在为学校的PHP计算器工作，我似乎不能让它工作。我不擅长PHP，不能搞清楚。当我运行它的会员资格和计算总数，无论我选择什么选项，它会自动切换到黄金会员资格。有什么想法吗？下面是代码：

<?php
$tax = 0;
$total = 0;
$membership = "gold";
$tennis = "no";
$racquetball = "no";
$golf = "no";
$child_care = "no";
$personal_trainer = "no";
$swimming_pool = "no";
function test_input($data) {
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    return $data;
}
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (!empty($_POST["tax"])) {
        $tax = test_input($_POST["tax"]);
    }
    
    if ($membership == "basic") {
        $total = 80;
    }
    elseif ($membership == "platinum") {
        $total = 100;
    }
    else {
        $total = 120;
    }
    if (isset($_POST["tennis"])) {
        $tennis = "yes";
        $total = $total + 15;
    }
    if (isset($_POST["racquetball"])) { 
        $racquetball = "yes";
        $total = $total + 20;
    }
    if (isset($_POST["golf"])) {
        $golf = "yes";
        $total = $total + 25;
    }
    if (isset($_POST["child_care"])) {
        $child_care = "yes";
        $total = $total + 15;
    }
    if (isset($_POST["personal_trainer"])) { 
        $personal_trainer = "yes";
        $total = $total + 20;
    }
    if (isset($_POST["swimming_pool"])) {
        $swimming_pool = "yes";
        $total = $total + 25;
    }
    $total = $total + $total * $tax;
    $total = round($total, 2);
}
?>

因为您在第4行将会员价值写为黄金，提交后漏调用会员发帖请求

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (!empty($_POST["tax"])) {
        $tax = test_input($_POST["tax"]);
    }
    $membership=$_POST["membership"];
    if ($membership == "basic") {
        $total = 80;
    }

添加此行$membership=$_POST[“成员资格”];
