如何使用wampserver在php中存储用户的数据？

Question

我有一个大学作业，我必须设计一个网站，我必须存储用户的详细信息。我做了一个谷歌搜索，我找到了一个脚本，适用于我的注册页面因此，我复制了该脚本的index.php页面，并且我已经使用wampserver在phpymadmin中创建了一个表格联系人，并且插入了3列用户名，电子邮件，消息。但是现在，当我试图输入一些细节并单击提交按钮时，页面正在刷新并且数据未存储在数据库中。

<form role="form" method="post" action="index.php"> 
 
        
 
\t <!-- Name --> 
 
\t <div class="row"> 
 
\t \t <div class="col-md-6"> 
 
\t \t \t <div class="form-group"> 
 
\t \t \t \t <input type="text" class="form-control" placeholder="Your name" name="name"> 
 
\t \t \t </div> 
 
\t \t </div> 
 

 
\t \t <!-- E-Mail --> 
 
\t \t <div class="col-md-6"> 
 
\t \t \t <div class="form-group"> 
 
\t \t \t \t <input type="email" class="form-control" placeholder="Email address" name="email"> 
 
\t \t \t </div> 
 
\t \t </div> 
 
\t </div> 
 

 
\t <!-- Message Area --> 
 
\t <div class="form-group"> 
 
\t \t <textarea class="form-control" name="message" placeholder="Write you message here..." style="height:232px;"></textarea> 
 
\t </div> 
 

 
\t <!-- Subtmit Button --> 
 
\t <button type="submit" class="btn btn-send" value="register"> 
 
\t \t Send message 
 
\t </button> 
 

 
</form>

<?php 

include("contact.php");//make connection here 
if(isset($_POST['register'])) 
{ 
    $Username=$_POST['name'];//here getting result from the post array after submitting the form. 
    $Email=$_POST['email'];//same 
    $Message=$_POST['message'];//same 


    if($Username=='') 
    { 
     //javascript use for input checking 
     echo"<script>alert('Please enter the name')</script>"; 
exit();//this use if first is not work then other will not show 
    } 

    if($Email=='') 
    { 
     echo"<script>alert('Please enter the email')</script>"; 
exit(); 
    } 

    if($Message=='') 
    { 
     echo"<script>alert('Please enter the message')</script>"; 
    exit(); 
    } 
//here query check weather if user already registered so can't register again. 
    $check_email_query="select * from contact WHERE Email='$Email'"; 
    $run_query=mysqli_query($dbcon,$check_email_query); 

    if(mysqli_num_rows($run_query)>0) 
    { 
echo "<script>alert('Email $user_email is already exist in our database, Please try another one!')</script>"; 
exit(); 
    } 
//insert the user into the database. 
    $insert_user="insert into contact (Username,Email,Message) VALUE ('$Username','$Email','$Message')"; 
    if(mysqli_query($dbcon,$insert_user)) 
    { 
     echo"<script>alert('Thank you for contacting us')</script>"; 
    } 

} 

?> 

Answer 1

1）添加在name='register'<button>。因为，您正在使用isset($_POST['register'])而且，不需要value="register"，因为您已经在按钮中声明了Send Message值。

<button type="submit" class="btn btn-send" name="register"> 
     Send message 
</button> 

2）在此查询更改VALUE到VALUES。

$insert_user="insert into contact (Username,Email,Message) VALUES ('$Username','$Email','$Message')";
