我正在尝试在我的网络项目上获取myContact Us表单以使用php，这样当输入完整的姓名和电子邮件地址时，它会向我发送一封电子邮件，然后显示成功消息，如果他们无法填写形成一个错误消息显示说他们再试一次。我的代码不起作用，我真的不明白为什么，它只是显示错误信息，无论什么甚至输入所有信息。这是我的PHP代码： -
`<?php`
$name = $email = "";
if (isset ($_POST ['fullname']))
$name = fix_string ($_POST ['fullname']);
if (isset ($_POST ['email'])) $email = fix_string ($_POST ['email']);
$email_to = "my@eamiladdress.com";
$email_subject = "Question asked";

$fail = validate_fullname($name);

任何人都可以帮助我，并告诉我哪里出错了。
我已根据建议对代码进行了一些更改。我不知道我真的不明白为什么它不起作用，它也没有使用css样式表。下面是新编辑的代码： -
<?php
if (isset($_POST ['fullname']) || isset($_POST ['email'])):
$name = fix_string($_POST ['fullname']);
$email = fix_string($_POST ['email']);
$email_to = "my@email.com";
$email_subject = "My E-Learning Tool Query";
$fail = validate_fullname($name);
$fail += validate_email($email);
if($fail!=""):
?>

答案 0 :(得分：0)
<强>更新
问题太小我错过了，
您需要使用.=而不是+=
$fail = validate_fullname($name);
$fail .= validate_email($email);
还从底部删除第二次出现的代码。
并关闭第一个html块上的表单标记
- 原始答案 -
除了遗漏form标签之外，您可以使用不同的sytnax重写if语句，这样您就可以正常输入html而无需回复它。
解决这个例子，它应该适合你。
<?php
if (isset($_POST ['fullname']) || isset($_POST ['email'])):
$name = fix_string($_POST ['fullname']);
$email = fix_string($_POST ['email']);
$email_to = "my@eamiladdress.com";
$email_subject = "Question asked";
$fail = validate_fullname($name);
$fail .= validate_email($email);
if($fail!=""):
?>
<!--Your error html-->
<?php
else:
?>
<!--Your success html-->
<?php
endif;
?>
<?php
else:
?>
<!--Your form html-->
<?php
endif;
//Your functions
?>
