Question

我正在处理邮件和表单。在我的表单中，我有一个从数据库填充的下拉菜单。数据库中的表有3列：id，facility和email。我需要邮件方查看设施并将$ mailto更改为数据库中的相应电子邮件地址。我真的很新，这让我难过了两天。

从 form.php下拉：

$queryData = "SELECT * FROM facilities";
$result = mysql_query($queryData);
?>

<select id="cust_Facility" name="cust_Facility">
<?php
while($row = mysql_fetch_array($result))
    {
        ?>
        <option value=<?php echo($row['id']); ?>><?php echo($row['facility']); ?></option>
        <?php
    }
?>
        </select>
<?php
?>

形式：

$emailSubject = 'Toner Request';
$mailto = '';
$email = 'Toner Sending Service';


$facilityField = mysql_real_escape_string($_POST['cust_Facility']);

$queryEmail = "SELECT * FROM facilities WHERE ";
$result = mysql_query($queryEmail);


if (isset($facilityField)) {
        echo "Facility is set";
        }
$body = <<<EOD
<br><hr><br>
Customer Information<br>
<br>
Facility: $facilityField <br>
EOD;

$headers = "From: $email\r\n"; // This takes the email and displays it as who this email is from.
$headers .= "Content-type: text/html\r\n"; // This tells the server to turn the coding into the text.
$success = mail($mailto, $emailSubject, $body, $headers); // This tells the server what to send.

?>

<!DOCTYPE html>
<html>
<head>
</head>

<body>

<h2>Success!</h2>

</body>
</html>

当我在表单上点击提交时，它会按预期回应$ facilityField。我不知道在那之后添加什么来根据$ facilityField中的值更改$ mailto。当我手动设置$ mailto时，我按预期收到了电子邮件。

新邮件：

<?php

include('db.inc');


$emailSubject = 'Toner Request';
$mailto = '';
$email = 'Toner Sending Service';


$facilityField = mysql_real_escape_string($_POST['cust_Facility']);


$queryEmail = "SELECT email FROM facilities WHERE facility = '".$facilityField."'";
$result = mysql_fetch_assoc($queryEmail);

echo "$result\n";

if (isset($facilityField)) {
        echo "Facility is set";
        }


$body = <<<EOD
<br><hr><br>
Facility: $facilityField <br>
EOD;



$headers = "From: $email\r\n"; // This takes the email and displays it as who this email is from.
$headers .= "Content-type: text/html\r\n"; // This tells the server to turn the coding into the text.
//$success = mail($mailto, $emailSubject, $body, $headers); // This tells the server what  to send.

?>

<!DOCTYPE html>
<html>
<head>
</head>

<body>

<h2>Success!</h2>

</body>
</html>

根据我对Pogrindis评论的理解，我做了上述修改。它不会回应$ result。它只是给了我回声“设施设置”和“成功！”。我还缺少什么？

最终工作代码：

$queryEmail = "SELECT email FROM facilities WHERE facility = '$facilityField'";
$result = mysql_query($queryEmail);
$result = mysql_fetch_assoc($result);
$mailto = $result['email'];

Answer 1

你的身体不是一根绳子。你应该收到一个错误。

你的$ body var应该是llike：

$body = "<<<EOD
<br><hr><br>
Customer Information<br>
<br>
Facility:". $facilityField ."<br>
EOD";

然后您就可以在邮件功能中使用它了。

目前，如果没有设置设施，它仍在尝试发送电子邮件。因此会发生未定义的错误。

如果您的If语句对此有帮助，请进行清理。

if (isset($facilityField)) {
    echo "Facility is set";
     $body = "<<<EOD
     <br><hr><br>
Customer Information<br>
<br>
Facility:". $facilityField ."<br>
EOD";

$headers = "From: $email\r\n"; // This takes the email and displays it as who this email is from.
$headers .= "Content-type: text/html\r\n"; // This tells the server to turn the coding into the text.
$success = mail($mailto, $emailSubject, $body, $headers); // This tells the server what to send.
            }
else
echo "Please set facility. "
?>

对于正在发生的事情更加冗长的事情也会有所帮助。

你的$ mailto;在页面顶部没有定义。

如果你在表格上有它，你应该有一个电子邮件输入（发送到这个电子邮件。）或者如果你喜欢一个联系页面，它应该设置。

if(isset($_POST['emailFormName']))
   $mailto = $_POST['emailFormName'];

现在通过名为emailFormName的表单输入设置mailto。

当您的更新询问如何根据设施填充mailto时。

您应该使用

$mailto = $_POST['cust_Facility'];

PHP邮件程序根据下拉菜单中的变量更改变量
