Question

我知道有一些与此相关的问题，但有c ++或其他语言。我收到此错误，我不确定我的功能有什么问题。

我的错误如下：

Fatal error: Uncaught ArgumentCountError: Too few arguments to function User::register(), 2 passed in C:\xampp\htdocs\register.php on line 39 and exactly 5 expected in C:\xampp\htdocs\classes\users.php:22 Stack trace: #0 C:\xampp\htdocs\register.php(39): User->register('ds', 'dsssssss') #1 {main} thrown in C:\xampp\htdocs\classes\users.php on line 22

我的功能是：

public function register($name, $surname, $username, $password, $email)
{
    try {
        $newPassword = password_hash($password, PASSWORD_DEFAULT);

        $stmt = $this->conn->prepare("INSERT INTO user(name, surname, username, password, email) 
                             VALUES(:name, :surname, :username, :password, :email)");

        $stmt->bindParam(":name", $name);
        $stmt->bindParam(":surname", $surname);
        $stmt->bindParam(":username", $username);   
        $stmt->bindParam(":password", $password);
        $stmt->bindParam(":password", $password);
        $stmt->bindParam(":email", $email);

        $stmt->execute();   

        return $stmt;   
}
    catch(PDOException $e) {
            echo $e->getMessage();
    }
}

Register.php文件：

  <!DOCTYPE html>
<?php
session_start();
require_once('classes/users.php');
$user = new User();

if($user->isLoggedIn()!="") {
    $user->redirect('home.php');
}

if(isset($_POST['submit'])) {
    $name = strip_tags($_POST['name']);
    $surname = strip_tags($_POST['surname']);
    $username = strip_tags($_POST['username']);
    $password = strip_tags($_POST['password']);
    $email = strip_tags($_POST['email']);

if($name=="") {
        $error[] = "provide username !";    
} else if($surname=="") {
        $error[] = "Provide surname!";  
  } else if ($username =="") {
      $error[] = "Provide username!";
    } else if($password=="") {
        $error[] = "provide password !";
      } else if(!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        $error[] = 'Please enter a valid email address !';
        } else if(strlen($password) < 6){
            $error[] = "Password must be atleast 6 characters"; 
          } else {
                try {
                    $stmt = $user->runQuery("SELECT username FROM user WHERE username=:username");
                    $stmt->execute(array(':username'=>$username));
                    $row=$stmt->fetch(PDO::FETCH_ASSOC);

                    if($row['username']==$username) {
                            $error[] = "sorry username already taken !";
                    } else {
                        if($user->register($username,$password)){   
                            $user->redirect('register.php?joined');
                        }
                    }

Answer 1

在php 7中而不是：

    public function register($name, $surname, $username, $password, $email)
{
...

使用：

public function register($name = null, $surname = null, $username = null, $password = null, $email = null)
{
...

Answer 2

我的托管公司将我们的PHP版本从7.0.x更新到7.1.x后，我遇到了同样的错误。他们认为，由于它是一个小的更新，它应该与以前的版本兼容。他们错了：here's来自迁移页面的不兼容列表。

在这个特殊情况下，之前会抛出关于函数调用缺少参数的警告的代码现在在OP的问题中抛出致命错误。

解决方案显然是提供其他答案所表明的适当参数。

Answer 3

你的方法需要5个参数，你只传递2：User->register('ds', 'dsssssss')

在Register.php中修改此行：

$user->register($username, $password)

到

$user->register($name, $surname, $username, $password, $email)

此外，您有两行$stmt->bindParam(":password", $password);

对于遇到此错误或类似问题的任何人，下面的答案有效！尝试使旧版本的WordPress WooCommerce在PHP 7.2上运行时遇到此错误。大声笑，我知道。 WooCommerce产品编辑屏幕为空白，出现以下错误（这破坏了产品标签）

Fatal error: Uncaught ArgumentCountError: Too few arguments to function product_custom_tab::product_tab_options(), 0 passed in wp-includes/class-wp-hook.php on line 286 and exactly 1 expected in /wp-content/plugins/woo-product-tab/includes/product_custom_tab.php:64 Stack trace: #0 wp-includes/class-wp-hook.php(286):

当转到product_custom_tab.php的第64行时。我改变了

public function product_tab_options($product_type)

到

public function product_tab_options($product_type = null)

它奏效了！感谢以下贡献者！你真的让我开心。感谢您在这里。谢谢！

Bytw：我曾尝试将其发布为评论，但不允许我这样做，因此我将其发布为答案。

遇到同样的问题。原来托管公司已经更新了 php 版本。我刚刚在数组中添加了另一个参数，并给了它一个 null 值

致命错误：未捕获ArgumentCountError：函数参数太少
