Question

我尝试提交此表单，但它只是使用$ Query代码上方的HTML重新加载页面。

inc / common.php是PDO数据库连接脚本，而inc / header.php只是我存储样式表的地方。

<?php 
ob_start();

require('inc/common.php'); ?>
<?php include_once "inc/header.php"; ?>
 <body class="register-page">
<div class="register-box">
  <div class="register-logo">
    <a href="../../index2.html">Our<b>Pet</b>.net</a>
  </div>
  <div class="register-box-body">
    <p class="login-box-msg">Register a new membership</p>
<?php   
    $query = " 
        SELECT 
            signupdisabled 
        FROM settings 
    "; 

    try 
    { 
        $stmt = $db->prepare($query); 
        $result = $stmt->execute(); 
    } 
    catch(PDOException $ex) 
    { 
        die("Failed to run query: " . $ex->getMessage()); 
    } 

    $row = $stmt->fetch(); 
    if($row['signupdisabled'] == 1) 
    { 
        ?>
        <div class="container" style="width:450px;">
            <div class="alert alert-danger" style="text-align: center;">

有人可以帮我吗？

Answer 1

您为表名使用了不正确的SVG 1.1 spec：

INSERT INTO 'users' 
            ^     ^

是常规报价。

删除它们

INSERT INTO users

或使用刻度

INSERT INTO `users`

使用setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION)会发出语法错误信号。

在打开连接后立即添加$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);。

请教：

标识符限定符：

http://php.net/manual/en/pdo.error-handling.php

将https://dev.mysql.com/doc/refman/5.0/en/identifier-qualifiers.html添加到文件的顶部，这有助于查找错误。

<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

// rest of your code

旁注：错误报告应仅在暂存时完成，而不是生产。

Answer 2

Sup man，我为你吸取了两件事。

第一个，就像Egzonr说的那样，尝试组织一下你的代码，我的意思是，你不需要创建分离的文件。但要尽量保持清洁。

另一件事是，创建另一个文件（只是为了测试，之后你会删除它），并尝试运行你的代码，但只是你的表单（删除所有其余的）。如果它工作，你将添加你的脚本的其他部分

我希望这对你有用。感谢

PHP表单没有提交数据，只是重新加载页面
