修复支持网址文章多图拖拽上传图片

将原有的/system/upload.php修改为下面代码

<?php

// TinyMCE 上传接口（最终自动域名版）

ini_set('display_errors', 0);

error_reporting(E_ALL & ~E_NOTICE);

header('Content-Type: application/json; charset=utf-8');

require(__DIR__ . '/common.php');

require(__DIR__ . '/../source/include/upload.php');

// 自动检测当前站点 URL（含协议与域名）

$scheme = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off') ? 'https' : 'http';

$host   = $_SERVER['HTTP_HOST'] ?? 'localhost';

$baseUrl = $scheme . '://' . $host;

// 如果 options 未定义，使用默认值

if (!isset($options) || !is_array($options)) {

    $options = [

        'upload_dir' => 'uploads',

        'site_url'   => $baseUrl

    ];

}

if (isset($_GET['act']) && $_GET['act'] === 'upload') {

    $savepath = '../' . $options['upload_dir'] . '/article/';

    $upload = new upload_file();

    $upload->make_dir($savepath);

    $file_field = isset($_FILES['imgFile']) ? 'imgFile' : 'file';

    if (!isset($_FILES[$file_field])) {

        http_response_code(400);

        echo json_encode(['error' => '未检测到上传文件']);

        exit;

    }

    $upload->init($_FILES[$file_field], $savepath);

    if ($upload->error_code === 0) {

        $upload->save_file();

        $relative_path = str_replace('../', '', $upload->attach['path']);

        $image_url = rtrim($options['site_url'], '/') . '/' . ltrim($relative_path, '/');

        echo json_encode(['location' => $image_url], JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);

        exit;

    } else {

        http_response_code(400);

        echo json_encode(['error' => $upload->error()], JSON_UNESCAPED_UNICODE);

        exit;

}
