Question

伙计我在我的php mvc代码中有错误，当我更新我的个人资料时它告诉我错误，同时更新l检查我的好，但它似乎很糟糕，不知道该怎么做。请帮帮我！

它一直警告我这个警告警告：PDOStatement :: execute（）：SQLSTATE [HY093]：参数号无效：绑定变量的数量与第37行的C：\ xampp \ htdocs \ php.dev \ classes \ Model.php中的标记数不匹配

这是我的classes / Model.php文件

abstract class Model {
    protected $dbh;
    protected $stmt;

    public function __construct() {
        $this->dbh = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME, DB_USER, DB_PASS);
    }

    public function query($query) {
        $this->stmt = $this->dbh->prepare($query);
    }

    // binds the prepare statement
    public function bind($param, $value, $type = null) {
        if (is_null($type)) {
            switch (true) {
                case is_int($value):
                    $type = PDO::PARAM_INT;
                    break;
                case is_bool($value):
                    $type = PDO::PARAM_BOOL;
                    break;
                case is_null($value):
                    $type = PDO::PARAM_NULL;
                    break;

                default:
                    $type = PDO::PARAM_STR;
            }
        }
        $this->stmt->bindValue($param, $value, $type);
    }

    public function execute() {
        $this->stmt->execute();
    }

    public function resultSet() {
        $this->execute();
        return $this->stmt->fetchAll(PDO::FETCH_ASSOC);
    }

    public function lastInsertId() {
        return $this->dbh->lastInsertId();
    }

    public function single(){
        $this->execute();
        return $this->stmt->fetch(PDO::FETCH_ASSOC);
    }

    public function emailExist() {
        $this->execute();
        return $this->stmt->fetch(PDO::FETCH_ASSOC);
    }
}

这里是我的controllers / user.php

class Users extends Controller{
    protected function profile(){
        if (!isset($_SESSION['is_logged_in'])) {//if user do not login they can not profile page
            header('Location: '.ROOT_URL.'shares');
        }
        $viewmodel = new UserModel();
        $this->returnView($viewmodel->profile(), true);
    }
}

这是我的models / user.php代码

public function profile(){
    // Sanitize POST
    //$post = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);

    if(isset($_POST['updateProfile'])){
        $name = $_POST['name'];
        $email = $_POST['email'];

        if (empty($_POST['name']) || empty($_POST['email'])) {
            Messages::setMsg('Please Fill All Form Fields', 'error');
            return;
        }

        // check if email is already taken
        $this->query('SELECT * FROM users WHERE email = :email');
        $this->bind(':email', $_POST['email']);
        $row = $this->emailExist();
        if ($row) {
            Messages::setMsg('Email already Exist', 'error');
            return;
        } else {
            # Update the MySQL
            $this->query("UPDATE users SET name =:name, email =:email WHERE id =:id");
            $this->bind(':name', $_POST['name']);
            $this->bind(':email', $_POST['email']);
            $this->execute();
            // Verify
            if($this->lastInsertId()){
                Messages::setMsg('Successfull Updated', 'success');
                return;
            } else {
                Messages::setMsg('Error while updating data', 'error');
                return;
            }
        }
    }

    return;
}

这里是我的观点/ users / profile.php代码

<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
        <div class="form-group">
            <label>Name</label>
            <input type="text" name="name" class="form-control" value="<?php echo $_SESSION['user_data']['name'];?>" />
        </div>
        <div class="form-group">
            <label>Email</label>
            <input type="text" name="email" class="form-control" value="<?php echo $_SESSION['user_data']['email'];?>" />

            <!-- input type="hidden" name="id" class="form-control" value="<!?php echo $_SESSION['user_data']['id']?>" / -->
        </div>
        <input class="btn btn-primary" name="updateProfile" type="submit" value="Submit" />
    </form>

如果用户不存在，则会运行：

$this->query("UPDATE users SET name =:name, email =:email WHERE id =:id");

尝试更新现有用户，而不是添加新用户。查询失败并显示错误，因为您没有将任何内容绑定到:id（您不应该，因为您正在尝试添加新用户）。

而是尝试此查询：

INSERT INTO users SET name =:name, email =:email

它应该有效。它仍然不允许您编辑用户，但它允许您添加新用户。
