Zip 下载 ZIP 更改 Wordpress 主题的文件夹名称

Question

我一直在尝试解决这个问题，但似乎找不到任何东西。

当您从 github“下载 ZIP”时，它不会为您提供您希望的“theme_name.zip”，而是“theme_name-master.zip”，当普通用户安装它时，混乱的文件夹名称会抛出子主题。

如何解决这个问题，以使 zip 下载不会改变任何内容？

Answer 1

为简单起见，您可以在某处托管一个脚本，下载脚本，重命名不带-master 的文件夹，然后重新压缩项目，然后将其作为下载发送给用户。

类似（需要 PHP5 >= 5.2.0、cURL、ZipArchive、safe_mode 和 open_basedir off）：

Fork it from GitHub ;p

Answer 2

这有点问题，我认为没有真正的解决方法，只有解决方法。我在插件方面遇到了同样的问题，只有部分解决方案：它只适用于插件/主题更新，而不是安装时。

从未尝试过，但也许可以在插件 (register_activation_hook) 或主题 (after_switch_theme) 激活时执行文件夹重命名。

我检查了核心，过滤器 upgrader_source_selection 适用于主题和插件。 repo slug 在 GitHub 的 URL 中：http://github.com/user/repo-name。

public static $repo_slug = 'repo-name';

add_filter( 'upgrader_source_selection', array( $this, 'rename_github_zip' ), 1, 3 );

/**
 * Removes the prefix "-master" when updating from GitHub zip files
 * 
 * See: https://github.com/YahnisElsts/plugin-update-checker/issues/1
 * 
 * @param string $source
 * @param string $remote_source
 * @param object $thiz
 * @return string
 */
public function rename_github_zip( $source, $remote_source, $thiz )
{
    if(  strpos( $source, self::$repo_slug ) === false )
        return $source;

    $path_parts = pathinfo($source);
    $newsource = trailingslashit($path_parts['dirname']). trailingslashit( self::$repo_slug );
    rename($source, $newsource);
    return $newsource;
}
