PHP-程序嘗試在項目中查找類時出現“找不到類”錯誤

[英]PHP - “Class not found” error when the program try to find class at the project

我從github組件下載了文件,簡化了文件驗證和上傳( https://github.com/brandonsavage/Upload )。

我將所有src文件夾都放在了www文件夾中(我正在使用WAMP)。

我還安裝了在github progaram上提供的composer.json

我使用以下代碼創建了index.html文件:

<!DOCTYPE html>
<html>
<body>

    <form action="up.php" method="POST" enctype="multipart/form-data">
     <input type="file" name="foo" value=""/>
     <input type="submit" value="Upload File"/>
    </form>

  </body>
   </html>

我直接從自述文件(在github項目)復制到up.php的操作是這樣的:

<?php
$storage = new \Upload\Storage\FileSystem(__DIR__."/".$sugar_config['upload_dir']);
$file = new \Upload\File('foo', $storage);

// Optionally you can rename the file on upload
$new_filename = uniqid();
$file->setName($new_filename);

// Validate file upload
// MimeType List => http://www.iana.org/assignments/media-types/media-types.xhtml
$file->addValidations(array(
    // Ensure file is of type "image/png"
    new \Upload\Validation\Mimetype('image/png'),

    //You can also add multi mimetype validation
    //new \Upload\Validation\Mimetype(array('image/png', 'image/gif'))

    // Ensure file is no larger than 5M (use "B", "K", M", or "G")
    new \Upload\Validation\Size('5M')
));

// Access data about the file that has been uploaded
$data = array(
    'name'       => $file->getNameWithExtension(),
    'extension'  => $file->getExtension(),
    'mime'       => $file->getMimetype(),
    'size'       => $file->getSize(),
    'md5'        => $file->getMd5(),
    'dimensions' => $file->getDimensions()
);

// Try to upload file
try {
    // Success!
    $file->upload();
} catch (\Exception $e) {
    // Fail!
    $errors = $file->getErrors();
}

在索引處單擊“上傳文件”按鈕后,瀏覽器將我定向到up.php文件,但出現此錯誤:

錯誤

我試圖用以下方法修復它:

  1. 添加namespace Upload; 像其他頁面一樣。
  2. 更改此行的路徑- $storage = new \\Upload\\Storage\\FileSystem(__DIR__."/".$sugar_config['upload_dir']);

什么都沒有。

=====更新-添加require dirname(__DIR__) . '\\Upload\\vendor\\autoload.php'; require dirname(__DIR__) . '\\Upload\\vendor\\autoload.php'; 我仍然遇到相同的錯誤-

(!)致命錯誤:在第7行的C:\\ wamp \\ www \\ Upload \\ up.php中找不到類“ Upload \\ Storage \\ FileSystem”

時間記憶功能位置

1 0.0084 250616 {main}().. \\ up.php:0

如果您不使用composer和composer的自動加載器,則它將不起作用,但是此程序包具有其自己的類自動加載器,請嘗試包括自動加載器並在腳本的頂部注冊它:

include 'src/Upload/Autoloader.php'
Autoloader::register();

在使用該類之前,您必須加載作曲家的類自動加載器。 如果沒有定義, Autoloader本質上就是尋找該類的函數

嘗試添加:

require __DIR__ . '/vendor/autoload.php';

在up.php的開頭(根據vendor文件夾相對於up.php位置調整路徑)

我通過添加新的存儲文件夾+在上傳之前添加src文件夾解決了該問題。

這是我當前的up.php頁面代碼:

<?php

require __DIR__ . '/vendor/autoload.php';

$storage = new \Upload\Storage\FileSystem('./stor');
$file = new \Upload\File('foo', $storage);



// Optionally you can rename the file on upload
$new_filename = uniqid();
$file->setName($new_filename);

// Validate file upload
// MimeType List => http://www.iana.org/assignments/media-types/media-types.xhtml
$file->addValidations(array(
    // Ensure file is of type "image/png"
    new \Upload\Validation\Mimetype('image/png'),

    //You can also add multi mimetype validation
    //new \Upload\Validation\Mimetype(array('image/png', 'image/gif'))

    // Ensure file is no larger than 5M (use "B", "K", M", or "G")
    new \Upload\Validation\Size('5M')
));

// Access data about the file that has been uploaded
$data = array(
    'name'       => $file->getNameWithExtension(),
    'extension'  => $file->getExtension(),
    'mime'       => $file->getMimetype(),
    'size'       => $file->getSize(),
    'md5'        => $file->getMd5(),
    'dimensions' => $file->getDimensions()
);

// Try to upload file
try {
    // Success!
    $file->upload();
} catch (\Exception $e) {
    // Fail!
    $errors = $file->getErrors();
}

謝謝 !
