Question

我一直在尝试创建一个小的PHP脚本，它将数据从html表单输入到phpmyadmin数据库，并遇到了一些我无法修复的错误，这是我的代码;

<html>
  <head>
    <title>Insert form data</title>
    <link rel="stylesheet" type="text/css" href="mystyle.css">
  </head>
 <body>
    <center>
    <h1>Online Stock Management</h1>
    <br>
    <p>Hello and welcome to Online Stock Management for small businesses. Please enter your details below to access your area.</p>
    <form action="insert.php" method="post">
        Business Name : <input type="text" name="businessName">
        <br>
        Name : <input type="text" name="name">
        <br>
        Email : <input type="text" name="email">
        <br>
            <input type="submit" value="Insert">

并且

<?php

$username = "root";
$password = "";
$hostname = "localhost"; 

//connection to phpmyadmin
$dbhandle = mysqli_connect($hostname, $username, $password) or die("Unable to connect to MySQL");

//connection to database 1012405 in phpmyadmin
mysql_select_db($dbhandle, '1012405') or die("Unable to connect to 1012405");

//insert html form into database
$insertquery= " INSERT INTO users(
        businessName,
        name,
        email
            ) VALUES (
        '".$_POST['businessName']."',
        '".$_POST['name']."',
        '".$_POST['email']."')";


$value = mysqli_query($dbhandle,$insertquery);
if (!$value){
die("Error could not insert " . mysqlerror());
}

这是我收到的错误 enter image description here

Answer 1

mysql_select_db($dbhandle, '1012405') or die("Unable to connect to 1012405");

我认为应该是

mysqli_select_db($dbhandle, '1012405') or die("Unable to connect to 1012405");

您也可以像这样连接到您的数据库

$dbhandle = mysqli_connect($hostname, $username, $password, '1012405') or die("Unable to connect to MySQL");

Answer 2

试试吧......

$dbhandle = mysqli_connect($hostname, $username, $password, '1012405') or die("Unable to connect to MySQL");

从表单插入数据到phpmyadmin时出错
