PHP 提交请求不起作用

Question

我创建了一个注册用户系统并分为两个页面。（registercontrol.php 和 register.php）

在register.php中，通常“提交”按钮应该将数据发送到registercontrol.php，但是当我单击“提交”按钮时没有任何反应。它只是刷新页面，什么也不做，成员表中没有数据。我错过了什么吗？

注册.php

<?php 

require('../includes/config.php');

//if logged in redirect to members page

if ($user->is_logged_in() ){ 

    header('Location: ../dashboard/index.php'); 

    exit(); 

}

//define page title

$title = 'Demo';

//include header template

require('../layout/header.php');

?>

<input type="text" name="fullname" id="fullname" class="form-control form-control-user" placeholder="Your Name" value="<?php if(isset($error)){ echo htmlspecialchars($_POST['fullname'], ENT_QUOTES); } ?>" tabindex="1" required>

<?php

    //check for any errors

    if (isset($infofn)){

       foreach ($infofn as $infofn){

            echo '<p class="p-3 text-info">'.$infofn.'</p>';

        }

    }                                   

?>

<input id="submit" type="submit" name="submit" value="Create Account" class="btn btn-primary btn-user btn-block" tabindex="6">

注册控制.php

<?php

require('../includes/config.php');

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

    //fullname validation

    $fullname = $_POST['fullname'];

    if (! $user->isValidFullname($fullname)){

        $infofn[] = 'Your name must be alphabetical characters';

    }   

}

//if form has been submitted process it

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

//if no errors have been created carry on

    if (!isset($infofn)){       

        try {

            //insert into database with a prepared statement

            $stmt = $db->prepare('INSERT INTO members (fullname) VALUES (:fullname)');

            $stmt->execute(array(

                ':fullname' => $fullname

            ));

            $id = $db->lastInsertId('memberID');

            

            //redirect to index page

            header('Location: register.php?action=joined');

            exit;

        //else catch the exception and show the error.

        } catch(PDOException $e) {

            $error[] = $e->getMessage();

        }

    }

}

您缺少一个表单元素，其action和method属性设置为您的其他脚本和 to post。在这种情况下action应该是registercontrol.php。如果不设置操作，表单将提交给自身，在本例中为register.php.像这样的事情应该可以解决问题（仅添加第一行和最后一行，其余的是您的代码）：<form action="registercontrol.php" method="post">&nbsp; &nbsp; <input type="text" name="fullname" id="fullname" class="form-control form-control-user" placeholder="Your Name" value="<?php if(isset($error)){ echo htmlspecialchars($_POST['fullname'], ENT_QUOTES); } ?>" tabindex="1" required>&nbsp; &nbsp; <?php&nbsp; &nbsp; &nbsp; &nbsp; //check for any errors&nbsp; &nbsp; &nbsp; &nbsp; if (isset($infofn)){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach ($infofn as $infofn){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; echo '<p class="p-3 text-info">'.$infofn.'</p>';&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; ?>&nbsp; &nbsp;<input id="submit" type="submit" name="submit" value="Create Account" class="btn btn-primary btn-user btn-block" tabindex="6"></form>
