我的Wordpress插件给了我WSOD

标签： wordpress-plugin wordpress custom-post-type wsod

我遵循了本教程http://wp.tutsplus.com/tutorials/plugins/a-guide-to-wordpress-custom-post-types-creation-display-and-meta-boxes/，我非常仔细地考虑过但是当我完成它时，我的插件可以工作，但它会给网站上的每个其他页面提供WSOD！一旦我停用插件，我的其他页面再次工作。我在使用MAMP的Mac上运行它，如果这有帮助的话。我希望在我上传和在线测试之前完成所有工作，即使我的网站不在线。

以下是我的代码。关于我做错了什么的任何想法？非常感谢你给我的任何帮助。

我拿出了一些部分，但将其缩小到下面导致问题的部分。

// Custom Template Dedicated to Custom Post Types

add_filter( 'template_include','include_template_function', 1 );

function include_template_function( $template_path ) {
    if ( get_post_type() == 'nm_portfolio' ) {
        if ( is_single() ) {
            // checks if the file exists in the theme first,
            // otherwise serve the file from the plugin
            if ( $theme_file = locate_template( array ( 'single-nm_portfolio.php' ) ) ) {
                $template_path = $theme_file;
            } else {
                $template_path = plugin_dir_path( __FILE__ ) . '/single-nm_portfolio.php';
            }
        }
            elseif ( is_archive() ) {
        if ( $theme_file = locate_template( array ( 'archive-nm_portfolio.php' ) ) ) {
            $template_path = $theme_file;
        } else { $template_path = plugin_dir_path( __FILE__ ) . '/archive-nm_portfolio.php';

        }
    }
    return $template_path;
}

我删除了add_filter( 'template_include','include_template_function', 1 );，现在似乎工作正常。

下面是我的代码，它们一起工作并且已经过编辑，以摆脱一些我不想要的东西。

感谢您的帮助！

没有定义'column_ordering'函数，尽管«add_filter（'request'，'column_ordering'）;» 从代码中删除这个过滤器，并且会出现烦恼！
