WordPress 不需要的媒体库 URL 在帖子中？

问题描述

当我们在 Google 上搜索我们博客上的内容时，我注意到我的震撼和恐惧，媒体 Library 的个人图像以某种方式生成自己的 URL，Google 以某种方式找到并编制索引！

例如这个页面：http://blog.stackoverflow.com/2008/08/special-development-team-podcast/

包含图片：http://blog.stackoverflow.com/wp-content/uploads/bio-jarrod-dixon.jpg

这是很好的，但不知何故，这个图像也暴露为自己的 URL 和”post”：http://blog.stackoverflow.com/2008/08/special-development-team-podcast/bio-jarrod-dixon/

这是非常不需要的！

我检查了 WordPress 中的媒体设置，并浏览了媒体库，但我无法找出一种方法来禁用此行为。有任何想法吗？

最佳解决方案

你所说的这个东西是不需要的只是 WordPress 中的正常功能，它不能被删除。但是，有些事情您可以将不需要的 URL 指向更有用的东西。

这是一个关于这个问题的论坛帖子，有一些有趣的修复和关于发生的事情的描述：

http://wordpress.org/support/topic/disable-attachment-posts-without-remove-the-medias

Attachments are actually a post type, so they take a row in the posts table like a post does, they will always have a URL available, in the same way that posts do to..

ie. example.com/?p=16

16 is the post ID, and like posts they will always be available by a URL like the above. Media files aren’t simply considered files, they have a more content like element to them, in that they have a record in the posts table that corresponds to them, just like a post or page does.

What you’re asking is how to stop the automatic existance of individual attachment URLs for each media item(not really possible because they’re essentially a post type, which means they’ll always be a URL for them).

Here’s a suggestion though, take any template(theme) file, index.php, page.php, archive.php or whatever you like, create a copy and rename it to image.php or attachment.php if you want to target all media. Open the file, remove the loop, save… and load up one of the attachment pages(like the one you provided before)..

My point being, all you need to do is create an attachment template file: http://codex.wordpress.org/Template_Hierarchy
http://codex.wordpress.org/Template_Hierarchy#Attachment_display

If you wanted to, in theory you could place a redirect into the attachment template so individual attachment views are redirected (or any number of other things you might want to do).

有人发布了一个 attachment.php，可以在您的/themes 文件夹中重定向：

<?php
header ('HTTP/1.1 301 Moved Permanently');
header ('Location: '.get_permalink($post->post_parent));
?>

次佳解决方案

我想到这是关于时间，我至少尝试我的手擦除附件页面。

这是我的第一枪

add_filter( 'attachment_fields_to_edit', 'wpse_25144_attachment_fields_to_edit', 10000, 2 );

function wpse_25144_attachment_fields_to_edit( $form_fields, $post ) {

    $url_type = get_option( 'image_default_link_type' );

    if( 'post' == $url_type ) {
        update_option( 'image_default_link_type', 'file' );
        $url_type = 'file';
    }

    $form_fields['url'] = array(
        'label'      => __('Link URL'),
        'input'      => 'html',
        'html'       => wpse_25144_image_link_input_fields( $post, $url_type ),
        'helps'      => __('Enter a link URL or click above for presets.')
    );

    return $form_fields;
}

function wpse_25144_image_link_input_fields($post, $url_type = '') {

    $file = wp_get_attachment_url($post->ID);

    if( empty( $url_type ) )
        $url_type = get_user_setting( 'urlbutton', 'file' );

    $url = '';
    if( $url_type == 'file' )
        $url = $file;

    return "
    <input type='text' class='text urlfield' name='attachments[$post->ID][url]' value='" . esc_attr($url) . "' /><br />
    <button type='button' class='button urlnone' title=''>" . __('None') . "</button>
    <button type='button' class='button urlfile' title='" . esc_attr($file) . "'>" . __('File URL') . "</button>
";
}

add_filter( 'query_vars', 'wpse_25144_query_vars', 10000, 2 );

function wpse_25144_query_vars( $wp_query_vars ) {

    foreach( $wp_query_vars as $i => $qv ) {
        if( in_array( $qv, array( 'attachment', 'attachment_id' ) ) )
            unset( $wp_query_vars[$i] );
    }
    return $wp_query_vars;
}

add_filter( 'attachment_link', 'wpse_25144_attachment_link', 10000, 2 );

function wpse_25144_attachment_link( $link, $id ) {

    $link = wp_get_attachment_url( $id );
    return $link;
}

add_filter( 'rewrite_rules_array', 'wpse_25144_rewrite_rules_array', 10000 );

function wpse_25144_rewrite_rules_array( $rewriteRules ) {

    foreach( $rewriteRules as $pattern => $query_string ) {
        if( false === strpos( $pattern, 'attachment' ) && false === strpos( $query_string, 'attachment' ) )
            continue;
        unset( $rewriteRules[$pattern] );
    }

    return $rewriteRules;
}

删除附件重写，更新附件链接指向附件文件 (而不是固定链接)，删除附件查询变量，并删除将附件链接到现在的 non-existant 附件永久链接的功能。

开放批评:)

第三种解决方案

您可以对其父页面的附件进行 301 重定向，如下所示：

<?php
/*
Plugin Name: Redirect Attachments to Parent (301)
Plugin URI: http://wordpress.stackexchange.com/questions/25144/unwanted-media-library-urls-in-posts
Description: Redirect any attachemnt pages to their parent's page with 301 redirection
Author: Ashfame
Version: 0.1
Author URI: http://www.ashfame.com/
*/

add_action( 'template_redirect', 'attachment_post_type_redirection' );

function attachment_post_type_redirection() {
    global $wp_query;
    if ( is_attachment() ) {
        wp_redirect( get_permalink( $wp_query->post->post_parent ), 301 );
    }
}

第四种方案

Yoast’s SEO plugin 在「永久链接」下有「将附件 URL 重定向到父帖子」。我使用此选项来解决问题。插件是惊人的
