Question

我有一个表单，其中一旦填写它就会向用户发送一封电子邮件，并根据他们在下拉列表中选择的选项给出价格。

我有一个if语句，可以看到在下拉列表中选择了哪个选项。在if语句中，它应该将$ Price变量设置为$ Price ='£300';

然后将$ Price变量添加到要发送的$ body变量中。 $ Price变量的值不会显示在电子邮件中，但是当我接受$ Price ='£300'时;在if语句中，它在电子邮件中可见。

我已确定问题不是选项下拉选项，因为当变量放在echo'Sent'，$ Price中时它会起作用;

PHP：

if ($Property_Value == '1to2') {
    $Price = '£300';
}


$name = $_POST['name'];
$email = $_POST['email'];
$from = 'From: BungeeDesign.com'; 
$to = $email;
$subject = 'Email Inquiry';
$Property_Value = $_POST['Property_Value'];

$body = "From: $name\n E-Mail: $email\n Price:\n $Price\n Selection:\n $Property_Value";



if ($_POST['submit']) {
    if (mail ($to, $subject, $body, $from)) { 
        echo 'Sent'; 
    } else { 
        echo '<p>Oops! An error occurred. Try sending your message again.</p>'; 
    }
}
?>

HTML：

 <div class="quoteForm">

  <form action="formAct.php" method="post">
    <li class="liFeilds">Name*:</li>
    <input type="text" name="name" placeholder="e.g. John Appleseed" required="yes" />
    <li class="liFeilds">Email*:</li>
    <input type="email" name="email" placeholder="e.g. email@email.com" required="yes" />

    <select class="propVal" name="Property_Value" required>
    <option value="1to2">£100,000 - £200,000</option>
    <option value="2to3">£200,001 - £300,000</option>
    <option value="3to4">£300,001 - £400,000</option>
    <option value="4to5">£400,001 - £500,000</option>

    <option value="6to7">£600,001 - £700,000</option>
    <option value="7to8">£700,001 - £800,000</option>
    <option value="8up">Over £800,000</option>
  </select>
    <button name="submit" type="submit" value="Submit">Get Estimate</button>
  </form>

</div>

Answer 1

在为变量

设置任何值之前，您正在检查$Property_Value

您必须先设置该值，然后检查该变量的任何条件，如：

$Property_Value = $_POST['Property_Value'];

if ($Property_Value == '1to2') {
    $Price = '£300';
}

在if语句中未设置变量
