我的代码有问题 我尝试使用 php 制作注册表单，但无法将数据插入数据库 这是我的代码

registration_form.php 注册表单 

 <body>
 <form method="post" action="register.php">
 <table border="0">

 <tr><td>username: </td><td><input type="text" name="username" /></td></tr>

 <tr><td>Password: </td><td><input type="password" name="password" /></td></tr>

 <tr><td>Confirm Password: </td><td><input type="password" name="confirm_password" /></td></tr>

 <tr><td></td><td><input type="submit" value="submit" /></td></tr>

 </table>
 </form>
 </body>
 </html>

注册.php 

 $con=mysql_connect("localhost","root","");
 /* Now, we select the database */
 mysql_select_db("login&register");

 /* Now we will store the values submitted by form in variable */
 $username=$_POST['username'];
 $pass=$_POST['password'];
 /* we are now encrypting password while using md5() function */
 $password=md5($pass);
 $confirm_password=$_POST['confirm_password'];

 /* Now we will check if username is already in use or not */
 $queryuser=mysql_query("SELECT * FROM register WHERE username='$username' ");
 $checkuser=mysql_num_rows($queryuser);
 if($checkuser != 0)
 { echo "Sorry, ".$username." is already been taken."; }
 else {

 /* now we will check if password and confirm password matched */
 if($pass != $confirm_password)
 { echo "Password and confirm password fields were not matched"; }
 else {

 /* Now we will write a query to insert user details into database */
 $insert_user=mysql_query("INSERT INTO register (username, password) VALUES ('$username',     '$password')");

 if($insert_user)
 { echo "Registration Succesfull"; }
 else
 { echo "error in registration".mysql_error(); }

 /* closing the if else statements */
 }}

 mysql_close($con);
 ?>

当我单击提交按钮时出现错误消息

您的 PHP 文件似乎被调用registration.php

您的表单操作是register.php，但您的 php 文件被调用registration.php，将您的表单操作更改为registration.php

您正在尝试以register.php您的形式访问，而不是registration.php

这看起来不像是数据库问题。而是找不到 register.php。您已将该文件保存为registration.php。
