Question

我正在尝试从HTML表单中收集信息，然后将数据传输到我的sql数据库。我用的是Zampp phpmyadmin。

当我点击提交时，输入的数据消失但弹出的成功不会弹出。没有错误。它只是没有被发送到数据库。直接在第三个IF语句之后是无效的ELSE语句 - 将数据传输到数据库 - 这是在第二个代码文件中。我不知道为什么。

此代码是索引页

此代码是将信息传输到数据库的functions.php。

<?php

 $con = mysqli_connect("localhost","root","","social_network") 
 or die("Connection was not established");

 function InsertUser(){
global $con;

if(isset($_POST['sign_up'])){
    $name = $_POST['u_name'];
    $pass = $_POST['u_pass'];
    $email = $_POST['u_email'];
    $country = $_POST['u_country'];
    $gender = $_POST['u_gender'];
    $b_day = $_POST['u_birthday'];
    $date = date("d-m-y");
    $status = "unverified";
    $posts = "No";

    $get_email = "select * from users where user_email='$email'";
    $run_email = mysqli_query($con,$get_email);
    $check = mysqli_num_rows($run_email);

    if($check==1){
        echo "<script>alert('Email has already been registered. Please try another one.')</script>";
        exit();     
    }
    if(strlen($pass)<8){
    echo "<script>alert('Password should be minimum 8 characters.')</script>";
        exit(); 
    }
    //this does not work. need to figure out why

    else {
        $insert = "INSERT into users (user_name,user_pass,user_email,user_country,user_gender,user_b_day,user_image,register_date,last_login,status,posts) values ('$name','$pass','$email','$country','$gender','$b_day','default.jpg','$date','$date','$status','$posts')";
        $run_insert = mysqli_query($con,$insert);

            if($run_insert){
                echo "<script>alert('Registration Successful!')</script>";
            }

    }


}



 }

 ?>

Answer 1

使用mysqli_error获取有意义的错误消息：

if($run_insert)
{
  echo "<script>alert('Registration Successful!')</script>";
}
else
{
  echo sprintf("Error %s executing %s", mysqli_error($con), $insert);
}
