我已经尝试了一些用于用户注册的代码。。每个gose精细代码都能工作，用户数据都存储在数据库中，但在register.php文件中，执行不会输入if（$user）语句作为用户详细信息的$response。。！如果我错了，请帮我纠正，有些人。。。听gose/DB_Functions.php/
<?php
class DB_Functions {
private $db;
// constructor
function __construct() {
try {
$hostname = "localhost";
$dbname = "miisky";
$dbuser = "root";
$dbpass = "";
$this->db = new PDO("mysql:host=$hostname;dbname=$dbname", $dbuser, $dbpass);
}
catch(PDOException $e)
{
echo $e->getMessage();
}
}
/**
* Storing new user
* returns user details
*/
public function storeUser($fname, $lname, $email, $password, $mobile) {
try {
$hash = md5($password);
$sql = "INSERT INTO users(fname, lname, email, password, mobile, created_at) VALUES ('$fname', '$lname', '$email', '$hash', '$mobile', NOW())";
$dbh = $this->db->prepare($sql);
$dbh->execute();
$result = $this->db->query($sql);
if ($result) {
// get user details
$id = $this->db->lastInsertId(); //last inserted id
$sql = "SELECT * FROM db_name WHERE email = '$email'";
$result = $this->db->query($sql);
$no_of_rows = $result->fetchColumn();
// returns confirmation message if completed
if ($no_of_rows > 0) {
return "existsandcompleted";
}
}
}
catch (Exception $e) {
$error = 'Error accessing database: ' . $e->getMessage();
}
}
}
?>
而这里gose的/register.php/文件的主要问题是。。。！！
<?php
require_once 'DB_Functions.php';
$db = new DB_Functions();
// json response array
$response = array("error" => FALSE);
if (isset($_POST['fname']) && isset($_POST['lname']) && isset($_POST['email']) && isset($_POST['password']) && isset($_POST['mobile'])) {
// receiving the post params
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$email = $_POST['email'];
$password = $_POST['password'];
$mobile = $_POST['mobile'];
// create a new user
$user = $db->storeUser($fname, $lname, $email, $password, $mobile);
if ($user) {
// user stored successfully
$response["error"] = FALSE;
$response["uid"] = $user["id"];
$response["user"]["fname"] = $user["fname"];
$response["user"]["lname"] = $user["lname"];
$response["user"]["email"] = $user["email"];
$response["user"]["created_at"] = $user["created_at"];
$response["user"]["updated_at"] = $user["updated_at"];
echo json_encode($response);
} else {
// user failed to store
$response["error"] = TRUE;
$response["error_msg"] = "Unknown error occurred in registration!";
echo json_encode($response);
}
} else {
$response["error"] = TRUE;
$response["error_msg"] = "Required parameters (fname, lname, email, password or mobile) is missing!";
echo json_encode($response);
}
?>
问题：
用户数据存储在数据库中，但在register.php文件中，执行不会输入if（$user）语句作为用户详细信息的$response
解决方案：
我很确定问题是因为下面这行，
$sql = "SELECT * FROM db_name WHERE email = '$email'";
^
我想应该是的，
$sql = "SELECT * FROM users WHERE email = '$email'";
^
此外，您的storeUser()方法应该是这样的：
// your code
public function storeUser($fname, $lname, $email, $password, $mobile) {
try {
$hash = md5($password);
$sql = "INSERT INTO users(fname, lname, email, password, mobile, created_at) VALUES ('$fname', '$lname', '$email', '$hash', '$mobile', NOW())";
$dbh = $this->db->prepare($sql);
if($dbh->execute()){
// get user details
$sql = "SELECT * FROM users WHERE email = '$email' LIMIT 1";
$dbh = $this->db->prepare($sql);
$result = $dbh->execute();
$rows = $dbh->fetch();
$n = count($rows);
if($n){
return $rows;
}
}
}
catch (Exception $e) {
echo 'Error accessing database: ' . $e->getMessage();
}
return false;
}
// your code
