javascript - 使用 php、ajax 和 javascript 计算订单结果，复选框不起作用

我刚刚创建了一个很好的工具来计算普通面包店的结果(相加、相乘并通过电子邮件发送总数)。

我的问题是我无法获取复选框输入中的值。我尝试了几种方法，但我能够从单选复选框获得的唯一值是 1(我认为该值是“true”)。其他一切都正常，但我仍然发现它有点冗长。

这是我的代码:

HTML(问题):

<fieldset>
                        <label>MEAT & CHEESE TRAYS</label><br>
                        <label>Executive Tray</label><br>
                        <label class='radiolabel'><input type="checkbox" name="Executive[]" value="45">Serves 10–15 people</label><br/>
                        <label class='radiolabel'><input type="checkbox" name="Executive[]" value="62">Serves 20–25 people</label><br/>
                        <label>Hospitality Tray</label><br>
                        <label class='radiolabel'><input type="checkbox" name="Hospitality[]" value="48">Serves 10–15 people</label><br/>
                        <label class='radiolabel'><input type="checkbox" name="Hospitality[]" value="65">Serves 20–25 people</label><br/>
                        <label>Meat & Cheese Nibbler</label><br>
                        <label class='radiolabel'><input type="checkbox" name="Nibbler[]" value="48">Serves 10–15 people</label><br/>
                        <label class='radiolabel'><input type="checkbox" name="Nibbler[]" value="65">Serves 20–25 people</label><br/>
                        <label>Sliced Cheese Tray</label><br>
                        <label class='radiolabel'><input type="checkbox" name="Sliced[]" value="48">Serves 10–15 people</label><br/>
                        <label class='radiolabel'><input type="checkbox" name="Sliced[]" value="65">Serves 20–25 people</label><br/>
                        <label>Cheese Nibbler</label><br>
                        <label class='radiolabel'><input type="checkbox" name="Cheese[]" value="48">Serves 10–15 people</label><br/>
                        <label class='radiolabel'><input type="checkbox" name="Cheese[]" value="65">Serves 20–25 people</label><br/>
                    </fieldset>

PHP(问题):

$value = implode(',', $_POST['Executive']);
$Body = "";
$Body .= "Here's the order from: ";

$Body .= "Executive Tray: ";
$Body .= $value;
$Body .= print_r($value);
$Body .= "\n";
$Body .= "Hospitality Tray: ";
$success = mail($EmailTo, $Subject, $Body, "From:".$email);

最佳答案

在您的 javascript submitForm() 函数中，您没有提交“Executive”、“Hospitality”、“Nibbler”、“Sliced”或“Cheese”字段。

在您的数据字符串中它们不存在...

data: "firstname=" + firstname + "&email=" + email + "&company=" + company + "&phonenumber=" + phonenumber + "&address=" + address + "&small=" + small + "&large=" + large + "&delights=" + delights + "&bagel=" + bagel + "&spinach=" + spinach + "&party=" + party + "&sweet=" + sweet + "&soft=" + soft + "&chocolate=" + chocolate + "&white=" + white + "&pickle=" + pickle,

这意味着这些字段永远不会提交给 PHP 表单处理程序，因此您无法从它们获取任何内容。

与其使用复杂而冗长的方法将每个输入分配给变量，然后自己制作数据字符串，为什么不尝试更简单且更面向 future 的方法，例如......

    var datastring = $("#calculatoform").serialize();
    $.ajax({
        type: "POST",
        url: "submitform.php",
        data: datastring,
        success : function(text){
            if (text == "success"){
                formSuccess();
            } else {
                formError();
            }
        }
    });
