我有一个用户表，其中包含以下列:用户 ID、用户名、名字、姓氏、电子邮件、 token 、密码、位置、电话。
我在两个不同的页面上有 2 个表单。 1.registration.php 2.user_info.php。
在registration.php中，我获取用户的电子邮件、用户名和密码。在 user_info.php 中，我获取用户的名字、姓氏、国家/地区、电话。
我想将两个表单数据插入 1 行。那么有什么办法吗？
现在用我的代码。它将两个表单中的信息插入数据库，但它在每个表单中插入 2 个不同的行数据。
这是我的registration.php
<?php
if (isset($_POST['signup-submit'])) {
$url = "https://www.google.com/recaptcha/api/siteverify";
$data = ['secret' => "[xxxx]", 'response' => $_POST['token'], 'remoteip' => $_SERVER['REMOTE_ADDR']];
$options = array('http' => array('header' => "Content-type: application/x-www-form-urlencoded\r\n", 'method' => 'POST', 'content' => http_build_query($data)));
$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);
$res = json_decode($response, true);
if ($res['success'] == true) {
require("dbh.inc.php");
require("functions.php");
$username = escape($_POST['username']);
$email = escape($_POST['email']);
$token = bin2hex(random_bytes(50));
$password = escape($_POST['password']);
$passwordRepeat = escape($_POST['confirm_password']);
if (empty($username) || empty($email) || empty($password) || empty($passwordRepeat)) {
header("Location: ../registration.php?error=emptyfields");
exit();
} elseif (!filter_var($email, FILTER_VALIDATE_EMAIL) || !preg_match("/^[a-zA-Z0-9]*$/", $username)) {
header("Location: ../registration.php?error=invalidmailuid");
exit();
} elseif (strlen($username) <= '6') {
header("Location: ../registration.php?error=usernamecheck");
exit();
} elseif (strlen($password) <= '8') {
header("Location: ../registration.php?error=passwordcheck");
exit();
} elseif ($password !== $passwordRepeat) {
header("Location: ../registration.php?error=passwordverify");
exit();
} else {
$sql = "SELECT username, email FROM users WHERE username = ? AND email = ?";
$stmt = mysqli_stmt_init($connection);
if (!mysqli_stmt_prepare($stmt, $sql)) {
header("Location: ../registration.php?error=sqlerror");
exit();
} else {
mysqli_stmt_bind_param($stmt, "ss", $username, $email);
mysqli_stmt_execute($stmt);
mysqli_stmt_store_result($stmt);
$resultCheck = mysqli_stmt_num_rows($stmt);
if ($resultCheck > 0) {
header("Location: ../registration.php?error=usermailtaken");
exit();
} else {
$sql = "INSERT INTO users(username, email, password, token, joined) VALUES(?, ?, ?, ?, now())";
$stmt = mysqli_stmt_init($connection);
if (!mysqli_stmt_prepare($stmt, $sql)) {
header("Location: ../registration.php?error=sqlerror2");
exit();
} else {
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
mysqli_stmt_bind_param($stmt, "ssss", $username, $email, $hashed_password, $token);
mysqli_stmt_execute($stmt);
header("Location: ../user_info.php");
exit();
}
}
}
}
mysqli_stmt_close($stmt);
mysqli_close($connection);
} else {
header("Location: ../registration.php?error=captcha");
exit();
}
} else {
header("Location: ../registration.php?error=emptyfields");
exit();
}
这是我的user_info.php
<?php
if (isset($_POST['profile-submit'])) {
require("dbh.inc.php");
require("functions.php");
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$location = $_POST['location'];
$phone = $_POST['phone_number'];
if (empty($first_name) || empty($last_name) || empty($location) || empty($phone)) {
header("Location: ../user_info.php?error=emptyfields");
exit();
} else {
$sql = "INSERT INTO users(first_name, last_name, location, phone) VALUES(?, ?, ?, ?)";
$stmt = mysqli_stmt_init($connection);
if (!mysqli_stmt_prepare($stmt, $sql)) {
header("Location: ../user_info.php?error=sqlerror");
exit();
} else {
mysqli_stmt_bind_param($stmt, "sssi", $first_name, $last_name, $location, $phone);
mysqli_stmt_execute($stmt);
header("Location: ../index.php?signup=success");
exit();
}
}
mysqli_stmt_close($stmt);
mysqli_close($connection);
} else {
header("Location: ../user_info.php?error");
exit();
}
最佳答案
您需要在user_info.php上使用UPDATE而不是INSERT
INSERT 添加新行。 https://dev.mysql.com/doc/refman/8.0/en/insert.html
INSERT inserts new rows into an existing table.
UPDATE 修改一行中的数据。 https://dev.mysql.com/doc/refman/8.0/en/update.html
UPDATE is a DML statement that modifies rows in a table.
当您执行UPDATE时，您需要添加一个WHERE子句以仅更新您想要的行。您通常使用主键来执行此操作，在本例中我假设主键是 user_id。
您可以使用mysqli_insert_id($connection)来获取INSERT查询运行后插入的最后一个ID。我建议将其存储在 $_SESSION 变量中，然后在 user_info.php 上访问它，而不是通过 POST 或 GET 传递。这样，其他用户就不能仅在 GET 或 POST 请求中输入 ID 并更新其他用户的信息。这里有一些代码可以指导您。
注册.php
//start the session
session_start();
...
...
} else {
mysqli_stmt_bind_param($stmt, "sssi", $first_name, $last_name, $location, $phone);
mysqli_stmt_execute($stmt);
$_SESSION['user_id'] = mysqli_insert_id($connection);
header("Location: ../index.php?signup=success");
exit();
}
}
....
....
user_info.php
....
....
if (empty($first_name) || empty($last_name) || empty($location) || empty($phone) || !isset($_SESSION['user_id')) {
header("Location: ../user_info.php?error=emptyfields");
exit();
} else {
$sql = "UPDATE users SET first_name = ?, last_name = ?, location = ?, phone =? WHERE user_id = ?";
$stmt = mysqli_stmt_init($connection);
if (!mysqli_stmt_prepare($stmt, $sql)) {
header("Location: ../user_info.php?error=sqlerror");
exit();
} else {
mysqli_stmt_bind_param($stmt, "sssi", $first_name, $last_name, $location, $phone, $_SESSION['user_id']);
mysqli_stmt_execute($stmt);
header("Location: ../index.php?signup=success");
exit();
}

关于php - 有没有办法从 2 个不同的表单插入数据并插入到列中的 1 行？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58940851/
