PHP 邮件中仅发送复选框中的一个值

Question

此联系表单仅将复选框列表中的一项发送到我的电子邮件。我想要它，以便将检查的所有内容发送给我，列表以逗号分隔（完成：Natural Oil light、Natural oil natural...）

我已经包含了contact.html 和send.php 页面，我想知道是否有人可以帮助指导我正确的方向或者只是修复代码。

发送.php：

    show_error("The e-mail address you entered is not valid.");
}

/* Let's prepare the message for the e-mail */
$message = "Hello!

A sample request form has been submitted by:

    <p><button onclick="goBack()">Go Back</button>

<?php
exit();
}
?>

Answer 1

对于多元素更改函数check_input

function check_input($data, $problem='')
{
if(is_array($data))
{
$data=implode(' ',$data);
}
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    if ($problem && strlen($data) == 0)
    {
        show_error($problem);
    }
    return $data;
}

Answer 2

你在这里只传递一个值$oak = check_input($_POST['oak']);

使用 $oak[] 发送多个文本。

Answer 3

使用这部分代码，以便在 send.php 中获取所有复选框值，以逗号分隔：

$oak = check_input($_POST['oak']);
$oak = implode("," $oak);
$grade = check_input($_POST['grade']);
$grade = implode("," $grade);
$finish = check_input($_POST['finish']);
$grade = implode("," $finish);
