【问题标题】：PHP checkboxes won't send Yes/No values in emailPHP 复选框不会在电子邮件中发送是/否值

【问题描述】：

我正在尝试通过制作一个简单的披萨订购系统来熟悉 PHP，该系统通过电子邮件发送大小、配料和订购者的信息。电子邮件发送良好，但电子邮件的浇头部分是空白的。我错过了什么？

谢谢！

【问题讨论】：

旁注：$_POST['Half Onions'] 等中的空格应不惜一切代价避免。使用下划线作为分隔符。
显示您的 HTML 表单。就目前而言，您的问题属于“不清楚”类别，然后是一些。

标签： php html email post checkbox

【解决方案1】：

替换文本字段名称之间的所有空格，例如：使用halfonions 而不是使用带有空格的文本名称，例如Half Onions

if(isset($_POST['halfonions']) &&   $_POST['halfonions'] == 'Yes') {

而不是

if(isset($_POST['Half Onions']) &&   $_POST['halfonions'] == 'Yes') {

【解决方案2】：

你没有设置你的变量，你只是将它们呼应出来：

/* the following code is currently not working */
$pepperoni = $_POST['pepperoni'];


if(isset($_POST['pepperoni']) && 
   $_POST['Pepperoni'] == 'Yes') 
{
    echo "pepperoni";
}
else
{
    echo "";
}

现在$pepperoni 变量将包含Yes（如果它被选中），没有其他内容。这是您当前尝试设置的唯一变量，消息中的其余变量未定义。

你可能想要这样的东西：

if(isset($_POST['pepperoni']) && 
   $_POST['pepperoni'] == 'Yes') 
{
    $pepperoni = "pepperoni";
}
else
{
    $pepperoni = "";
}

对于您在消息中使用的所有变量。

您可以将其简化为：

$pepperoni = isset($_POST['pepperoni']) ? 'pepperoni' : '';
                           ^ or however it is spelled in the html...

因为价值并不重要。

【讨论】：

旁注：pepperoni 和 Pepperoni 完全是两个不同的动物。除非 OP 两者都有。更多的原因是我没有给出答案。我们不知道 OP 表单中的内容。
哦，如果不尝试，永远不知道 ;-)
@Fred-ii- 但一般的答案是，主要问题是回显而不是分配。我认为...
当然，包括单词之间的空格。
现在终于有阳光了，我正在考虑自己“推迟”这个工作日，干杯！ ;-)

【解决方案3】：

我认为变量中有空格，例如“Half Pepperoni”或“Half Mushrooms”！！
