点击提交按钮后没有任何反应

我无法弄清楚我在代码中错过了什么。我if else语句正在工作，因为我可以看到我的表单，并在提交后我想在标签后看到消息。我如何知道提交按钮是否响应。点击提交按钮后没有任何反应

<?php 

$output_form = true; 

$fname = ""; 
$lname = ""; 
$address1 =""; 
$address2 =""; 
$city = ""; 
$state = ""; 
$zipcode = ""; 

if (isset($_POST['submit'])) { 

print_r($_POST); 

    $fname = trim($_POST["firstName"]); 
    $lname = trim($_POST['lastName']); 
    $address1 = trim($_POST['address1']); 
    $address2 = trim($_POST['address2']); 
    $city = trim($_POST['city']); 
    $state = trim($_POST['state']); 
    $zipcode = trim($_POST['zipcode']); 

} 

?> 
<!DOCTYPE html> 
<html> 
    <head> 
     <title>Assignment 3 </title> 
     <link rel="stylesheet" type="text/css" href="style.css"> 

    </head> 
    <body> 

     <?php 
     if ($output_form) { 
     ?> 

     <h1>Enter your information</h1> 

     <form name="userform" action="<?= $_SERVER['PHP_SELF'] ?>" method="post"> 

      <p>First Name: <input name="firstName" type="text" value="<?= $fname ?>"></p> 
      <p>Last Name: <input name="lastName" type="text" value="<?= $lname ?>"></p> 
      <p>Address 1: <input name="address1" type="text" value="<?= $address1 ?>"></p>

      <input class="button" name="submit" type="button" value="Button">

     <?php 
      } else { 

     ?>

       <p class="result">

       </p> 

     <?php 
     } 
     ?> 

    </body> 
</html>

按键不提交，所以'$ _ POST [ '提交']'未设置。检查别的东西。 – adeneo

@Rainy Day如果能解决您的问题，请接受我的回答。 – rumman0786

让你的输入型提交

<input class="button" name="submit" type="button" value="Button">

应该

<input class="button" name="submit" type="submit" value="Button">
