Question

在您提出任何问题之前，我会在8周内搜索答案，我的问题是：我正在建立一个论坛，只是一个业余项目，并且我已经设置了所有内容，用户，主题，回复，单身，电子邮件确认等。

在我的注册脚本中，我想检查用户是否选择了图像。如果他这样做，则将图像作为Blob文件上传。我做到了，而且效果很好。但是，如果用户在注册时没有选择图像，则当他查看自己的个人资料或创建线索时，基本上是在他显示自己的个人资料图像时，其显示的是“无此类文件”图像。我希望在发送查询以添加用户之前，先检查他是否选择了图像，否则，请选择名为“ images / default.jpg”的文件并上传。

这是我当前的注册文件：

register.php

<?php session_start(); ?>

        <link rel="stylesheet" type="text/css" href="style/registerstyle.css">

register_parse.php

<?php
session_start();
//error_reporting(!8);
//error_reporting(!2);
include_once("connect.php");

$username = $_POST['username'];
$password = $_POST['password'];
$password2 = $_POST['password2'];
$email = $_POST['email'];

if ($username && $password && $password2 && $email) {
    if ($password == $password2) {
        $query = "SELECT * FROM users WHERE username='".$username."' OR email='".$email."' LIMIT 1";
        $result = mysqli_query($connection, $query);

        if (mysqli_fetch_row($result)) {
            echo "Username or Email taken. If you already have an account, connect to it instead.";
        } else {
            $confirmcode = rand();
            $query2 = "INSERT INTO users (username, password, email, confirmed, confirm_code) VALUES ('".$username."', '".$password."', '".$email."', '0', '".$confirmcode."')";
            $result2 = mysqli_query($connection, $query2) or die(mysqli_error($connection));

            $message = "

            ;

            if ($result2) {
                mail($email, "Coder'sCrux Email Confirmation", $message, "From: coderscrux#gmail.com");

                echo "Registration Complete! Please confirm your email to unlock all features, or go back to the <a href='index.php'>main website</a>.";
            }
        }
    } else {
        echo "Your passwords do not match.";
    }
}

?>

谢谢！
