Question

我正在设置调查问卷，以便在我们的常见问题解答页面底部，我是PHP新手，这是我第一次尝试连接数据库（没有教程）。

我已经设置了HTML页面，设置了PHP，并在MySQL中设置了一个表。

每次提交时数据库都会创建一个新行，但所有行都有“0”而不是分配给输入/ div的值。请帮忙！

编辑：我将HTML更新为现在的形式，但是，当我提交时，我得到了404（并且行根本没有更新。可能有什么问题？

以下是HTML：

<?php
    //error_reporting(0);
    require 'db/connect.php';
?>

这是php文档：

<?php

    define('DB_NAME', 'staterequirements');
    define('DB_USER', 'myuser');
    define('DB_PASSWORD', 'mypass');
    define('DB_HOST', 'localhost');

    $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);

    if(!$link) {
        die('Could not connect: ' . mysql_error());
    }

    $db_selected = mysql_select_db(DB_NAME, $link);

    if(!$db_selected) {
        die('Can\'t use ' . DB_NAME . ' : ' . mysql_error());
    }

    $Q1 = (isset($_POST['Q1']) ? $_POST['Q1'] : null);
    $Q2_1 = (isset($_POST['Q2_1']) ? $_POST['Q2_1'] : null);
    $Q2_2 = (isset($_POST['Q2_2']) ? $_POST['Q2_2'] : null);
    $Q2_3 = (isset($_POST['Q2_3']) ? $_POST['Q2_3'] : null);
    $Q2_4 = (isset($_POST['Q2_4']) ? $_POST['Q2_4'] : null);
    $Q2_5 = (isset($_POST['Q2_5']) ? $_POST['Q2_5'] : null);
    $Q2_6 = (isset($_POST['Q2_6']) ? $_POST['Q2_6'] : null);
    $Q3 = (isset($_POST['Q3']) ? $_POST['Q3'] : null);

   $sql = "INSERT INTO response (Q1, Q2_1, Q2_2, Q2_3, Q2_4, Q2_5, Q2_6) VALUES ('$Q1', '$Q2_1', '$Q2_2', '$Q2_3', '$Q2_4', '$Q2_5', '$Q2_6')";

    if (!mysql_query($sql)) {
        die('Error: ' . mysql_error());
    }

    mysql_close();

}?>

Answer 1

这些要点是您问题的一部分。

此：

<div id="questions" action="connect.php" method="post">

应该是<form而不是div：

<form id="questions" action="connect.php" method="post">

而且：

    <div class="ratings" name="Q1">
        <div class="rating" id="rating1" value="1">Not at all helpful</div>
        <div class="rating" id="rating2" value="2">Not very helpful</div>
        <div class="rating" id="rating3" value="3">Somewhat helpful</div>
        <div class="rating" id="rating4" value="4">Very helpful</div>
        <div class="rating" id="rating5" value="5">Extremely helpful</div>
    </div>

我不确定您是否要使用下拉菜单select或checkboxes或radio按钮或输入，但divs无效 form elements

我还想指出，强烈建议您使用MySQLi_和/或PDO代替弃用的MySQL_，因为您的（已发布）代码 open to injection
