如何使用mysql连接使用php创建简单的html表单

Question

I have been learning web designing. 我一直在学习网页设计。 As a first I learned to create a html form using php with mysql database. 最初，我学会了使用php和mysql数据库创建html表单。

The form works perfectly. 形式完美。 But whenever I click the submit button, it shows Your file was not found error. 但是，每当我单击“提交”按钮时，它就会显示“找不到文件”错误。

Here's my html code, 这是我的html代码，

<html>    
<head>    
    <title>Registration Form</title>    
</head>    
<body>    
    <link href = "registration.css" type = "text/css" rel = "stylesheet" />    
    <h2>Fun Quizzes</h2>    
    <form name = "form1" action="modified.php" method = "post" enctype = "multipart/form-data" >    
        <div class = "container">    
            <div class = "form_group">    
                <label>Questions:</label>    
                <input type = "text" name = "Questions" value = "" required/>    
            </div>    
            <div class = "form_group">    
                <label>Correct Answer :</label>    
                <input type = "text" name = "Correct_Answer" value = "" required />    
            </div>    
            <div class = "form_group">    
                <label>wrong - 1 :</label>    
                <input type = "text" name = "wrong_1 " value = "" required/>    
            </div>    
            <div class = "form_group">    
                <label>wrong - 2:</label>    
                <input type = "text" name = "wrong_2" value = "" required/>    
            </div>
            <div class = "form_group">    
                <label>wrong - 3 :</label>    
                <input type = "text" name = "wrong_3" value = "" required/>    
            </div>  
            <div form action="C:\Users\user\Desktop\Students_Profiles\connection.php" method="post">    
                <label>Submit:</label>    
                <input type = "submit"/>    
            </div>                      
        </div>    
    </form>    
</body>

And here's my php code, 这是我的php代码，

<?php
// Grab our POSTed form values
// Note that whatever is enclosed by $_POST[""] matches the form input elements
$Questions = $_POST["Questions"];
$Correct_Answer = $_POST["Correct_Answer"];
$wrong_1 = $_POST["wrong_1"];
$wrong_2 - $_POST["wrong_2"];
$wrong_3 - $_POST["wrong_3"];


// Connect to our DB with mysql_connect(<server>, <username>, <password>)
$sql_connection = mysql_connect("localhost", "root", "");

mysql_select_db("test_series_quizz", $sql_connection);

// Probably should check to make sure the connection was successful
// But I'm too lazy...
$sql = "INSERT INTO history_of_india (
            Questions,
            Correct_Answer,
            wrong_1,
            wrong_2,
            wrong_3

        )
        VALUES (
            '$Questions',
            '$Correct_Answer',
            '$wrong_1',
            '$wrong_2',
            '$wrong_3'

        )"

mysql_query($sql, $sql_connection);

mysql_close($sql_connection);
?>

My sql connection is Localhost, user name is root and no password. 我的sql连接是Localhost，用户名是root，没有密码。 Any help would be appreciated. 任何帮助，将不胜感激。 Thanks in advance. 提前致谢。

Answer 1

PHP code must save with name PHP代码必须使用名称保存

modified.php modified.php

and save same location where html saved. 并保存html保存的位置。 remove this line 删除此行
<div form action="C:\\Users\\user\\Desktop\\Students_Profiles\\connection.php" method="post"> rewrite submit button as <input type = "submit" value="submit" /> <div form action="C:\\Users\\user\\Desktop\\Students_Profiles\\connection.php" method="post">将提交按钮重写为<input type = "submit" value="submit" />

In your php code there is small mistake in 在您的php代码中有一个小错误

$wrong_2 - $_POST["wrong_2"];
$wrong_3 - $_POST["wrong_3"];

Forgot = sign, rewrite as 忘了=符号，改写为

$wrong_2 = $_POST["wrong_2"];
$wrong_3 = $_POST["wrong_3"];

Answer 2

When you click on the submit button, the form is redirected to the action in your form tag 当您单击“提交”按钮时，表单将重定向到表单标签中的操作

<form name = "form1" action="modified.php" method = "post" enctype = "multipart/form-data" >

in this case action="modified.php" 在这种情况下， action="modified.php"

If the page does not exist then you get the error you described. 如果该页面不存在，那么您将得到所描述的错误。

also, in your modified.php page, you need a check if the $_POST exists before you start with the insert code. 同样，在您的Modifyed.php页面中，您需要在插入代码开始之前检查$ _POST是否存在。 You where also missing a ; 你在哪里也想念;

    // Grab our POSTed form values
    // Note that whatever is enclosed by $_POST[""] matches the form input elements
    $Questions = $_POST["Questions"];
    $Correct_Answer = $_POST["Correct_Answer"];
    $wrong_1 = $_POST["wrong_1"];
    $wrong_2 - $_POST["wrong_2"];
    $wrong_3 - $_POST["wrong_3"];


    // Connect to our DB with mysql_connect(<server>, <username>, <password>)
    $sql_connection = mysql_connect("localhost", "root", "");

    mysql_select_db("test_series_quizz", $sql_connection);

    // Probably should check to make sure the connection was successful
    // But I'm too lazy...
    $sql = "INSERT INTO history_of_india (
                Questions,
                Correct_Answer,
                wrong_1,
                wrong_2,
                wrong_3

            )
            VALUES (
                '$Questions',
                '$Correct_Answer',
                '$wrong_1',
                '$wrong_2',
                '$wrong_3'

            )";

    mysql_query($sql, $sql_connection);

    mysql_close($sql_connection);
}else{
    echo "Nothing submitted";
}
