PHP-File不'；救不了

我希望用户能够上传一张以他的用户名命名的个人资料图片，这样我以后就可以轻松地调用它。问题是，没有文件保存在所需的文件夹中。文件夹名为“profilePictures”，当用户的用户名调用其中应有图片时，该文件夹名为空。我试着把它修好了，但运气不好。我做错了什么

代码：

<?php

class User {
    public function __construct( $username, $password, $passwordRepeat, $email, $firstName, $familyName, $age, $sex, $question, $answer, $car, $profilePicture ) {
        $this->username       = $username;
        $this->password       = $password;
        $this->passwordRepeat = $passwordRepeat;
        $this->email          = $email;
        $this->firstName      = $firstName;
        $this->familyName     = $familyName;
        $this->age            = $age;

        $this->answer         = $answer;
        $this->car            = $car;
        $this->profilePicture = $profilePicture;
    }

    public function savePicture() {
        if ( isset( $_POST["register_new"] ) ) {
            $profiles = "profiles/$this->username.txt";

首先确保您对
profilePictures
地图具有写入权限。假设您得到许可，我认为它在以下两行中失败：

$pictureFile = $pictureDir . basename(["profilePicture"]["name"][ $this->username ] );
$pictureTemp = $_FILES["profilePicture"]["name"][ $this->username ];

请尝试此操作，而不是上面的两行：

//Do not add the username here, because it isn't defined anywhere.
//Also you didn't define $_FILES here, and basedir isn't neccessary since "name" only contains the filename
$pictureFile = $pictureDir . $_FILES["profilePicture"]["name"];

//To get the current picture use tmp_name
$pictureTemp = $_FILES["profilePicture"]["tmp_name"];

该函数将变成如下所示：

public function savePicture() {
    if ( isset( $_POST["register_new"] ) ) {
        $profiles = "profiles/$this->username.txt";
        if ( $this->password !== $this->passwordRepeat ) {

        } else if ( file_exists( $profiles ) ) {

        } else if ( $this->age < 18 ) {

        } else {
            $pictureDir  = "profilePictures/";

            //Do not add the username here, because it isn't defined anywhere.
            //Also you didn't define $_FILES here, and basedir isn't neccessary since "name" only contains the filename
            $pictureFile = $pictureDir . $_FILES["profilePicture"]["name"];

            //To get the current picture use tmp_name
            $pictureTemp = $_FILES["profilePicture"]["tmp_name"];

            $pictureType = pathinfo( $pictureFile, PATHINFO_EXTENSION );
            $uploadFile  = 1;
            $check       = getimagesize( $pictureTemp );

            if ( $check !== false ) {
                $uploadFile = 1;
            } else {
                require "register.html";
                echo "<p>File is not an image</p>";
                $uploadFile = 0;
            }

            /*
            if (file_exists($pictureFile)) {
                echo "<p>File already exists</p>";
            }
            */

            if ( $_FILES["profilePicture"]["size"] > 200000 ) {
                echo "File is too large! We accept files that are less than 2 MB";
                $uploadFile = 0;
            }

            if ($pictureType != "jpg" && $pictureType != "png" && $pictureType != "jpeg" && $pictureType != "gif") {
                echo "<p>Sorry, only JPG, JPEG, PNG & GIF files are allowed.</p>";
                $uploadFile = 1;
            }

            if ( $uploadFile == 0 ) {
                echo "<p>File was not uploaded</p>";
            } else {
                move_uploaded_file( $pictureTemp, $pictureFile );
            }
        }
    }
}

您是否检查了权限以确保web服务器能够写入目录？在
移动上传的文件（）
功能中使用的
$pictureTemp
应该是上传到服务器上的文件。目前还没有
$\u FILES['profilePicture']['tmp\u name']
@Shocm我正在本地主机上执行此操作您应该检查
移动上传的\u file
的返回值。不要只是假设它成功了。@Denki-localhost与否，权限就是权限。如果执行脚本的用户帐户没有对输出目录的写入权限，则上载将失败。感谢您的评论。我照你说的做了，但还是一事无成。这真的很奇怪。出于某种原因，它说，
$uploadFile=1”。变量的值会立即被覆盖“未使用”是什么意思？你的意思是
$uploadFile=0？
