来自表单的数据未使用 php 添加到数据库表中

Question

我正在使用 Xampp 服务器并希望将数据添加到数据库表中。我不知道我在这里做错了什么。服务器已启动并正在运行。选择框中的数据未插入到数据库中。我是 php 新手。

编辑：我已经编辑了我的代码。我收到此错误：

在此服务器上找不到请求的 URL。引用页面上的链接似乎是错误的或过时的。请将该错误告知该页面的作者。

Answer 1

在 Sub.php 中，您在 $Comments 的这一行中错过了引号 '

$sql = "INSERT INTO problemdet (Response, Area, Rating, Comments, ImprovementPlan) VALUES ('$Response', '$Area', '$Rating', 
'$Comments', '$ImpPlan')";

在 Test.php 中，您错过了 select 的 name 属性并将其放在选项标签中，因此将其更改为

<select name="Response[]">        

       <option >--Select Function--</option> ...

来自

<select>        

        <option name="Response">--Select Function--</option> ...

在 Test.php 中，您有多个具有相同名称属性的输入，而在 Sub.php 中，您只会得到一个值，因此将 name 属性中的名称更改为数组

<select name="Response[]"> ...
<textarea name = "Comments[]"> ...

然后：

$_POST['Response'][0] 
$_POST['Response'][1]
$_POST['Comments'][0]
$_POST['Comments'][1]
//and so on if you have to many you can write it in a loop

编辑说明

您应该指定名称属性（在您的情况下为响应）是一个数组的浏览器（因为有多个具有相同名称属性的选择输入 - 响应，因此它应该是响应 []）

比在 php 中你应该从数组中一一获取值 （比如 $_POST['Response'][0],$_POST['Response'][1],.. upto count($_POST['response'])）

你的例子

<select name="Response[]">
    <option value="first_0">first</option>
    <option value="second_0">second</option>
    <option value="third_0">third</option>
</select>

<select name="Response[]">
    <option value="first_1">first</option>
    <option value="second_2">second</option>
    <option value="third_3">third</option>
</select>

如果您从第一个选择中选择第三个_0，从第二个选择中选择第二个_2，那么当您在 php 中获取值时

echo $get_select_value_1 = $_POST['Response'][0];
echo $get_select_value_2 = $_POST['Response'][1];

//output will be
third_0 //--$get_select_value_1
second_2 //--$get_select_value_2

编辑 2 - 为同一列插入多个值

$Response1 = $_POST['Response'][0];
$Response2 = $_POST['Response'][1];

$sql = "INSERT INTO problemdet (Response) VALUES ('$Response1'),('$Response2')";//upto so on

编辑 3 - 测试代码

<!DOCTYPE html>
<html>
<head>
    <title>test</title>
</head>
<body>
<form name="form2" action= "register.php" method="post">
    <select name="Response[]">
    <option value="first_0">first</option>
    <option value="second_0">second</option>
    <option value="third_0">third</option>
</select>

<select name="Response[]">
    <option value="first_1">first</option>
    <option value="second_2">second</option>
    <option value="third_3">third</option>
</select>
<input type="submit" name="submit">
</form>

</body>
</html>

sub.php

<?php
if(isset($_POST['submit'])){
    echo $Response1 = $_POST['Response'][0];
echo $Response2 = $_POST['Response'][1];
}

?>
