Question

我无法弄清楚为什么我的PHP代码不会从我的表单中取出名字，我希望你们能帮忙。

其他所有内容都通过电子邮件发送，只是第一个名称字段是element_1_1。

这是PHP：

$<?php
$errors = ''; 
$myemail = 'example@example.co.uk';
if( empty($_POST['element_1_1'])  ||
empty($_POST['element_1_2'])  ||
empty($_POST['element_3']) ||
empty($_POST['element_2'])  ||
empty($_POST['element_5'])  ||
empty($_POST['element_4']))

$name = $_POST['element_1_1'];
$lastname = $_POST['element_1_2'];
$email_address = $_POST['element_3']; 
$number = $_POST['element_2'];
$area = $_POST['element_5'];
$discount = $_POST['element_4'];

if (!preg_match(
"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", 
$email_address))
{
    $errors .= "\n Error: Invalid email address \n";
}

if( empty($errors))
{
$to = $myemail; 
$email_subject = "";
$email_body = "".

"\n First Name:   $name \n  \n Second Name:   $lastname \n  \n Email:   $email_address \n  \n Phone Number:   $number \n \n Area(s):   $area \n \n Discount:   $discount \n".


$headers = "From: example@example.co.uk\n"; 
$headers .= "Reply-To: $email_address";

mail($to,$email_subject,$email_body,$headers);
//redirect to the 'thank you' page
header('Location: http://www.example.co.uk');
} 
?>

<body>

<?php
echo nl2br($errors);
echo "";
echo " \n <a href='http://www.example.com'>Go     Back</a> \n";
?>


</body>
</html>

以下是表格：

Answer 1

if( empty($_POST['element_1_1'])  ||
empty($_POST['element_1_2'])  ||
empty($_POST['element_3']) ||
empty($_POST['element_2'])  ||
empty($_POST['element_5'])  ||
empty($_POST['element_4']))

$name = $_POST['element_1_1'];
$lastname = $_POST['element_1_2'];
$email_address = $_POST['element_3']; 
$number = $_POST['element_2'];
$area = $_POST['element_5'];
$discount = $_POST['element_4'];

你错过了这里的curley括号吗？我会假设这个或类似于curley括号，取决于你想做什么。

if( empty($_POST['element_1_1'])  ||
empty($_POST['element_1_2'])  ||
empty($_POST['element_3']) ||
empty($_POST['element_2'])  ||
empty($_POST['element_5'])  ||
empty($_POST['element_4']))
{
$name = $_POST['element_1_1'];
$lastname = $_POST['element_1_2'];
$email_address = $_POST['element_3']; 
$number = $_POST['element_2'];
$area = $_POST['element_5'];
$discount = $_POST['element_4'];
}

你还想用if语句做什么？你正在检查其中一个是否为空，然后将它们全部设置好？或者您应该检查其中一个是否为空，然后向用户发送一条消息，其中一个字段需要填写？然后你应该把它改成这样的东西：

if( empty($_POST['element_1_1'])  ||
    empty($_POST['element_1_2'])  ||
    empty($_POST['element_3']) ||
    empty($_POST['element_2'])  ||
    empty($_POST['element_5'])  ||
    empty($_POST['element_4']))
    {
    do something;    }
else {
$name = $_POST['element_1_1'];
    $lastname = $_POST['element_1_2'];
    $email_address = $_POST['element_3']; 
    $number = $_POST['element_2'];
    $area = $_POST['element_5'];
    $discount = $_POST['element_4'];

}

Answer 2

你的if语句在做什么？

if( empty($_POST['element_1_1'])  ||
empty($_POST['element_1_2'])  ||
empty($_POST['element_3']) ||
empty($_POST['element_2'])  ||
empty($_POST['element_5'])  ||
empty($_POST['element_4']))

这似乎与任何东西无关，但是如果它们都不为空，那么$ name没有设置（它是if语句之后的第一行，只有在if语句为真时才会被调用）

我认为你应该执行所有的行，这需要围绕它们的花括号。

表格没有取名字
