【问题描述】：
我是 PHP 新手，对以下联系表格有疑问： 变量：$empresa = $_POST['empresa'];不工作......我不明白问题出在哪里。当我尝试在发送的电子邮件中使用它时，它只是不显示。
$received_subject = 'Has sido contactado desde www.company.com por ' . $name . '. Empresa' . $empresa . '.' ;
**这是我正在使用的 PHP：** 提前致谢
<?php
if(!$_POST) exit;
function isEmail($email) {

我的表格在这里：
<form method="post" action="contact.php" name="contactform" id="contactform">
<fieldset id="contact_form">
<label for="name">
<input type="text" name="name" id="name" placeholder="Nombre *">
</label>
<label for="empresa">
<input type="text" name="empresa" id="empresa" placeholder="Empresa *">
</label>
<label for="email">
<input type="email" name="email" id="email" placeholder="E-Mail *">
</label>
<label for="phone">
<input type="text" name="phone" id="phone" placeholder="Número de teléfono">
</label>
<label for="comments">
<textarea name="comments" id="comments" placeholder="Mensaje *"></textarea>
</label>
<p class="obligatorio"> * = Obligatorio</p>
<input type="submit" class="submit btn btn-default btn-black" id="submit" value="Enviar">
</fieldset>
</form>
【问题讨论】：
-
你的
form在哪里？ -
我在代码下方添加了我的表单
-
var_dump($_POST)的结果是什么？ -
很抱歉，但不知道如何将您的问题应用到代码中
-
在
if(!$_POST) exit;行之后添加命令（不要忘记；最后）
