如何限制v3中出现的图像。5媒体库模式，仅显示附加到特定帖子id的内容？
我正在创建一个前端管理模板，允许多个作者编辑任何特定的帖子，因此需要限制每篇帖子上显示的内容，而不是特定用户上传的内容。
上载模式基于Mike Jolley\'s upload modal tutorial. 它被修改为在body类中查找post id，并将上传的媒体附加到$pid。
这是迄今为止完整的modal js：
// Uploading files
jQuery(document).ready(function($) {
var file_frame;
var wp_media_post_id = wp.media.model.settings.post.id; // Store the old id
var classes = $(\'body\').attr(\'class\'); // get all classes from <body> element
var set_to_post_id = classes.match(/postid-(\\d+)/)[1]; // pid to attach media to
jQuery(document).on(\'click\', \'.upload_image_button\', function(){
event.preventDefault();
// If the media frame already exists, reopen it.
if ( file_frame ) {
// Set the post ID to what we want
file_frame.uploader.uploader.param( \'post_id\', set_to_post_id );
// Open frame
file_frame.open();
return;
} else {
// Set the wp.media post id so the uploader grabs the ID we want when initialised
wp.media.model.settings.post.id = set_to_post_id;
}
// Create the media frame.
file_frame = wp.media.frames.file_frame = wp.media({
title: jQuery( this ).data( \'uploader_title\' ),
button: {
text: jQuery( this ).data( \'uploader_button_text\' ),
},
multiple: false // Set to true to allow multiple files to be selected
});
// When an image is selected, run a callback.
file_frame.on( \'select\', function() {
// We set multiple to false so only get one image from the uploader
attachment = file_frame.state().get(\'selection\').first().toJSON();
// Do something with attachment.id and/or attachment.url here
// Restore the main post ID
wp.media.model.settings.post.id = wp_media_post_id;
});
// Finally, open the modal
file_frame.open();
});
// Restore the main ID when the add media button is pressed
jQuery(\'a.add_media\').on(\'click\', function() {
wp.media.model.settings.post.id = wp_media_post_id;
});
});
媒体库上的两个主要权威WPSE线程只处理用户的限制。

我不确定这就是你要找的。此代码将；“锁定”；上载以在媒体面板中仅显示“上载到此帖子”
add_action( \'admin_footer-post-new.php\', \'firmasite_mediapanel_lock_uploaded\' );
add_action( \'admin_footer-post.php\', \'firmasite_mediapanel_lock_uploaded\' );
function firmasite_mediapanel_lock_uploaded() { ?>
<script type="text/javascript">
jQuery(document).on("DOMNodeInserted", function(){
// Lock uploads to "Uploaded to this post"
jQuery(\'select.attachment-filters [value="uploaded"]\').attr( \'selected\', true ).parent().trigger(\'change\');
});
</script>
<?php }

我花了两天的时间寻找解决方案，来自Ünsal Korkmaz的答案对我来说并不适用。最后，我找到了正确的答案，我想与大家分享。
只是想澄清一下，Ünsal Korkmaz的回答将在媒体管理器窗口中预先选择“上传到此帖子”选项，但如果您在自己的插件、主题、自定义元框等中使用媒体管理器，并且您正在构建自己的媒体管理器框架，这将不起作用。即使它可以工作，您也会有一个预选的过滤器，但这并不能有效地将媒体库限制为定义的post附件。
以下是我找到的解决方案：
//Chame the selector to fit your code
jQuery(\'#manage-gallery-button\').click(function(e) {
e.preventDefault();
var frame = wp.media({
title : \'Pick the images for the gallery of this entry\',
frame: \'select\',
multiple : true,
library : {
type : \'image\',
//HERE IS THE MAGIC. Set your own post ID var
uploadedTo : wp.media.view.settings.post.id
},
button : { text : \'Insert\' }
});
frame.on(\'close\',function() {
// get selections and save to hidden input plus other AJAX stuff etc.
var selection = frame.state().get(\'selection\');
var gallery_ids = new Array();
var my_index = 0;
selection.each(function(attachment) {
gallery_ids[my_index] = attachment[\'id\'];
my_index++;
});
var ids = gallery_ids.join(",");
//Store ids in my hidden input
jQuery(\'#gallery-ids\').val(ids);
Refresh_Gallery(ids);
});
frame.on(\'open\',function() {
//Preselect attachements from my hidden input
var selection = frame.state().get(\'selection\');
ids = jQuery(\'#gallery-ids\').val().split(\',\');
ids.forEach(function(id) {
attachment = wp.media.attachment(id);
attachment.fetch();
selection.add( attachment ? [ attachment ] : [] );
});
});
frame.open();
});
