我正在PHP中练习OOP，在提交涉及子类的表单数据时遇到问题

我想做的是：根据产品类型（通用、工具或电子）提交表单数据。我担心的是无法提交能够区分不同产品类型的表格

以下是
产品类
（基类）：

这就是我遇到问题的地方：

$electronic = new Electronics();

    $product_form = false;

    $product->setTitle($_POST['title']);
    $product->setDescription($_POST['description']);
    $product->setPrice($_POST['price']);             

    $product->insertProduct();

    /*$tool->setTitle($_POST['title']);

    $tool->setPrice($_POST['price']);
    $tool->setShipper($_POST['shipper']);
    $tool->setWeight($_POST['weight']);
    if (!empty($tool->getTitle()) && !empty($tool->getDescription()) &&     is_numeric($tool->getPrice()) && !empty($tool->getShipper()) && !empty($tool-    >getWeight())) {
        echo 'Tool submitted <br/>';
        //echo '<a href="addProduct.php">Go Back</a>';
        $tool->insertTool();
    }
} else {

}

我会这样做：


  • 将所有计算移到文件顶部
    • 

  • 将prodType移动到表单中
    • 

  • 我总是显示表单。在一个实例中是编辑，在另一个实例中是创建。但是您需要为“product_id”添加一个隐藏的输入
    • 
像这样：
    

    <?php
require_once('Product.php');
require_once('Electronics.php');
require_once('Tools.php');

$product    = new Product();
$tool       = new Tools();
$electronic = new Electronics();
if (isset($_POST['submit'])){
     $prodType = $_POST['prodType'];
     if($prodType == 'general') {
        $product_form = false;
        $product->setTitle($_POST['title']);
        $product->setDescription($_POST['description']);
        $product->setPrice($_POST['price']);             
        $product->insertProduct();
    } else if($prodType == 'tools') {

    } else if ($prodType == 'elecronics') {
    } else {
        // echo this message in the form. 
        $msg = 'Invalid product type';
    }
}
?>

    <br/><br/>

    实际的行为是什么？有任何错误消息吗？@FelisCatus，没有错误消息——当我选择“常规”并按“提交”时，表单会清除，但不会向数据库发送任何内容将您的prodType选择选项放入表单内部。这可能会克服你的问题你在哪里选择“一般”。我是否缺少
    选择
    框？我可以让它正确提交“常规”产品，但无法提交“工具”产品。这就是我试图做的验证：
    if（isset（$\u POST['submit']）&&（isset（$\u POST['prodType']）=='tools'）{//$tool->insertTool（）；}
    注意：我在创建了提交一般产品的验证（如您上面所建议的）之后尝试这么做，谢谢！在过去的几天里，我一直在“放屁”，这正是我想要做的！
