Question

我的PHP邮件正在向我发送邮件，并且昨天正在100％工作，但今天它发送了，但每个字段都是第一个发送的。例如布局是：

Hi my name is, $name.

I would like to rent an apartment from, $apartment.

My VEI Bank account number is, $account.

Will you also check to see if our firm is purchasing from your commercial for the 10% discount? I work at, $cname.

Please contact me back via email, $email.

但是，电子邮件看起来像这样：

Hi my name is, 1.

I would like to rent an apartment from, 1.

My VEI Bank account number is, 1.

Will you also check to see if our firm is purchasing from your commercial for the 10% discount? I work at, 1.

Please contact me back via email, 1

如果你想查看代码页面是synergy.x10host.com/business.php

提前感谢！

Answer 1

您将1作为输出的原因是因为布尔值（true）正在转换为字符串。在PHP中转换为字符串的布尔true为1。

如果查看PHP手册，isset将返回一个布尔值。如果您想在设置之前检查并查看该值是否存在，则可以使用以下内容：

$cname = isset($_POST['cname']) ? $_POST['cname'] : "Some other text";
$cemail = isset($_POST['cemail']) ? $_POST['cemail'] : "Some other text";
$bank = isset($_POST['bank']) ? $_POST['bank'] : "Some other text";
$ceo = isset($_POST['ceo']) ? $_POST['ceo'] : "Some other text";
$sqft = isset($_POST['sqft']) ? $_POST['sqft'] : "Some other text";

这样，isset检查是否设置了$ _POST ['cname']。如果已设置，则使用该值。否则，它会使用您提供的其他一些默认文本。

Answer 2

Isset返回布尔值。这就是你发送＆＃39; 1＆＃39;在你的邮件中

$cname = isset($_POST['cname']);
$cemail = isset($_POST['cemail']);
$bank = isset($_POST['bank']);
$ceo = isset($_POST['ceo']);
$sqft = isset($_POST['sqft']);

PHP邮件发送，但不正确
