Question

我试图为客户编写注册页面，但每次都会出现此错误。

无法运行查询：SQLSTATE [HY093]：参数号无效：参数未定义

我已按照本教程：http://untame.net/2013/06/how-to-build-a-functional-login-form-with-php-twitter-bootstrap/ 数据库是这样的： DB

代码是这样的：

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/oauth2/token");

//Here you will have to add your options, I think this code will bring you far :-)
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_TIMEOUT, 30);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

我已经看到所有变量都没问题，我也不知道错误在哪里。

我的config.php

    <?php


        require("config.php");
    if(empty($_SESSION['user'])) 
    {
        header("Location: index.php");
        die("Redirecting to index.php");

    if(!empty($_POST))

        if(empty($_POST['username']))

        if(empty($_POST['password']))

我只添加了3件事：empresa，nombre和apellidos，这些都不是教程中我需要的。

提前致谢，约翰。

你在这里传递了错误的参数：

    // Check if the username is already taken
    $query = " 
        SELECT 
            1 
        FROM users 
        WHERE 
            username = :username 
    "; 
    $query_params = array( ':username' => $_POST['username'] ); 
    $query_params = array( ':nombre' => $_POST['nombre'] );
    $query_params = array( ':empresa' => $_POST['empresa'] );
    $query_params = array( ':apellidos' => $_POST['apellidos'] );

您尝试传递的参数太多，但每次都要覆盖$query_params。在本节中取出hombre，empress和apellidos，它应该提交。
