Question

我创建了一个非常基本的html注册页面，要求用户输入他们的名字，姓氏，电子邮件和密码。但是，只有名字和名字记录在phpmyadmin的数据库中，电子邮件和密码显示为空白cloumns。我试图删除并再次添加表和列没有任何运气，我已经更改了变量名称，也没有运气。不太清楚该怎么做。

Php代码

<?php

$servername = "localhost";
$username = "";
$password = "";
$dbname = "";

//Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
//echo "Connected successfully";

$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$email = $_POST['email'];
$password_ = $_POST['password_'];

if (isset($_POST['register'])) {
    register($first_name,$last_name,$_email,$password,$conn);
}


$conn->close();


function register($first_name,$last_name,$email,$password,$conn) {
//    echo $first_name . " " . $last_name . " " . $student_id . " " . $email;

$sql = "INSERT INTO `register` (`first_name`, `last_name`, `email`, `password_`) VALUES ('$first_name', '$last_name', '$email', '$password_')";
if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

}
?>

Answer 1

要获取_POST变量，您的输入表单必须具有名称属性。对于您的电子邮件表单，您只指定了ID而没有指定名称。返回并添加名称=＆＃39;电子邮件＆＃39;属性，它应该工作。密码相同。
