Question

我正在为网站创建注册页面。当我提交表单时，数据不会发送到数据库。有人知道为什么会这样吗？以下代码来自名为register.php的脚本我不明白为什么它不会发送到我的mysql数据库。昨晚我有一个错误“phpMyAdmin - 错误无法启动会话而没有错误，请检查PHP和/或webserver日志文件中给出的错误并正确配置PHP安装。” 但现在它的工作。可能是那个吗？

<?php
echo "<h1>Register</h1>";

$submit = filter_input(INPUT_POST, 'submit');
//form data
$fullname = strip_tags (filter_input(INPUT_POST, 'fullname'));
$username = strtolower(strip_tags (filter_input(INPUT_POST, 'username')));
$password = strip_tags(filter_input(INPUT_POST, 'password'));
$repeatpassword = strip_tags(filter_input(INPUT_POST, 'repeatpassword'));
$date = date("Y-m-d");


if ($submit)
{
//open database
$connect=mysql_connect("localhost","root","mypasswordwouldgohere");
mysql_select_db("phplogin");

$namecheck = mysql_query("SELECT username FROM users WHERE username='$username'" );
$count = mysql_num_rows($namecheck);

if($count!=0)
{
die("Username already taken, please choose another");
}

//check for existence
if($fullname&&$username&&$password&&$repeatpassword)
{
    if ($password==$repeatpassword)
    {
    //check char length of username and fullname
        if (strlen($username)>25||strlen($fullname)>25)
        {
        echo "Length of username or full name is too long!";
        }
        else
        {
        //check password length 
            if (strlen ($password)>25 || strlen ($password)<6)
            {
            echo "Password must be between 6 and 25 characters";
            }
            else
            {
            $password = md5($password);
            //register user 


            $queryreg = mysql_query("INSERT INTO users VALUES           ('','$fullname','$username','$password','$date',)");
            die ("You have been registered! <a href='index.php'>Return  to the login page</a>");



            }   
        }   
    }
    else echo "Your passwords do not match";
}
else echo "Please fill in <b>all</b> fields!";

}

Answer 1

此处有SQL语法错误"INSERT INTO users VALUES ('','$fullname','$username','$password','$date',)"。在查询中删除最后一个'，'。

Mysql_query不会发送到数据库
