<?php
    $host="localhost";
    $dbuser="root";
    $pass="******";
    $dbname="learn";
    $con = mysqli_connect ($host, $dbuser, $pass, $dbname);
    if (mysqli_connect_errno ())
    {
        die ("Connection Failed!" . mysqli_connect_error());
    }
    else
    {
    echo "Connected to database {$dbname} ";
    }

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

        $lname=$_POST ['lname'];
        $email=$_POST ['email'];
        $pswrd=$_POST ['pswrd'];

            $sql = $con->query ("INSERT INTO users ( fname, lname, email, pswrd,)
                     VALUES ( ' {$fname} ' , ' {$lname} ' , ' {$email} ' , ' {$pswrd} ' , ')" );

Answer 1

从您的 <form> 标签中删除 action="submit"。 action="{URL}" 属性 "specifies where to send the form-data when a form is submitted" - 发送回同一个 url.

时不需要它

例如变化：

<form action="submit" method="post"><br>

至：

<form method="post"><br>

Answer 2

下面，action 应该是处理 code.In 这种情况的 php 文件的名称，可能是 $_SERVER['PHP_SELF']。

<div id="signupform">
   <form action="submit" method="post"><br>

Answer 3

您应该在另一个文件中有您的连接信息。

创建名为 Config.php 的文件 为只读

<?
/* Attempt MySQL server connection. Assuming you are running MySQL
    server with default setting (user 'root' with no password) */
    $link = mysql_connect("localhost", "root", "******", "demo");

    // Check connection
    if($link === false){
        die("ERROR: Could not connect. " . mysql_connect_error());
    }

?>

创建一个名为 Insert.php

的文件

    <?
    include 'Config.php';
    ?>
    <?

    // Escape user inputs for security
    $first_name = mysql_real_escape_string($link, $_POST['firstname']);
    $last_name = mysql_real_escape_string($link, $_POST['lastname']);
    $email_address = mysql_real_escape_string($link, $_POST['email']);
    $pswr = mysql_real_escape_string($link, $_POST['pswrd']);

    // attempt insert query execution
    $sql = "("INSERT INTO users ( fname, lname, email, pswrd,)
                     VALUES ( ' {$fname} ' , ' {$lname} ' , ' {$email} ' , ' {$pswrd} ' , ')" );
    if(mysql_query($link, $sql)){
        echo "Records added successfully.";
    } else{
        echo "ERROR: Could not able to execute $sql. " . mysql_error($link);
    }

    // close connection
    mysql_close($link);
    ?>

您的表格：

<div id="signupform">
            <form action="Insert.php" method="post"><br>
                <input type="text" id="fname" name="fname" placeholder="First name">
                <input type="text" id="lname" name="lname" placeholder="Last name"><br><br>
                <input type="text" id="email" name="email" placeholder="Email address">
                <input type="password" id="pswrd" name="pswrd" placeholder="Password"><br><br>
                <input type"submit" value="Submit">
            </form>
        </div>
