试着涵盖大多数解决方案：
使用tb_show("", "media-upload.php?type=image&TB_iframe=true");和window.send_to_editor
问题：没有标准的wp.media UI
在js代码中：
jQuery("#my_button").click(function() {
tb_show("", "media-upload.php?type=image&TB_iframe=true");
return false;
});
window.send_to_editor = function(html) {
console.log(html);
tb_remove();
}
使用wp.media({frame: 'post'})
问题：无法自定义UI元素，例如：title，button
在js代码中：
function clearField(){
#remove file nodes
#...
}
var frame = wp.media({frame: 'post'});
frame.on('close',function() {
var selection = frame.state().get('selection');
if(!selection.length){
clearField();
}
});
frame.on( 'select',function() {
var state = frame.state();
var selection = state.get('selection');
if ( ! selection ) return;
clearField();
selection.each(function(attachment) {
console.log(attachment.attributes);
});
});
frame.open();
将wp.media.editor与wp.media.editor.open( editor_id )
问题：无法自定义UI元素，例如：title，button
使用wp.media重写wp.media.controller.Library并在attachment
select
问题：复杂......，但一旦你明白了，这一切都有道理，这是我的最终解决方案
在js代码中：
/**
* Please attach all the code below to a button click event
**/
//create a new Library, base on defaults
//you can put your attributes in
var insertImage = wp.media.controller.Library.extend({
defaults : _.defaults({
id: 'insert-image',
title: 'Insert Image Url',
allowLocalEdits: true,
displaySettings: true,
displayUserSettings: true,
multiple : true,
type : 'image'//audio, video, application/pdf, ... etc
}, wp.media.controller.Library.prototype.defaults )
});
//Setup media frame
var frame = wp.media({
button : { text : 'Select' },
state : 'insert-image',
states : [
new insertImage()
]
});
//on close, if there is no select files, remove all the files already selected in your main frame
frame.on('close',function() {
var selection = frame.state('insert-image').get('selection');
if(!selection.length){
#remove file nodes
#such as: jq("#my_file_group_field").children('div.image_group_row').remove();
#...
}
});
frame.on( 'select',function() {
var state = frame.state('insert-image');
var selection = state.get('selection');
var imageArray = [];
if ( ! selection ) return;
#remove file nodes
#such as: jq("#my_file_group_field").children('div.image_group_row').remove();
#...
//to get right side attachment UI info, such as: size and alignments
//org code from /wp-includes/js/media-editor.js, arround `line 603 -- send: { ... attachment: function( props, attachment ) { ... `
selection.each(function(attachment) {
var display = state.display( attachment ).toJSON();
var obj_attachment = attachment.toJSON()
var caption = obj_attachment.caption, options, html;
// If captions are disabled, clear the caption.
if ( ! wp.media.view.settings.captions )
delete obj_attachment.caption;
display = wp.media.string.props( display, obj_attachment );
options = {
id: obj_attachment.id,
post_content: obj_attachment.description,
post_excerpt: caption
};
if ( display.linkUrl )
options.url = display.linkUrl;
if ( 'image' === obj_attachment.type ) {
html = wp.media.string.image( display );
_.each({
align: 'align',
size: 'image-size',
alt: 'image_alt'
}, function( option, prop ) {
if ( display[ prop ] )
options[ option ] = display[ prop ];
});
} else if ( 'video' === obj_attachment.type ) {
html = wp.media.string.video( display, obj_attachment );
} else if ( 'audio' === obj_attachment.type ) {
html = wp.media.string.audio( display, obj_attachment );
} else {
html = wp.media.string.link( display );
options.post_title = display.title;
}
//attach info to attachment.attributes object
attachment.attributes['nonce'] = wp.media.view.settings.nonce.sendToEditor;
attachment.attributes['attachment'] = options;
attachment.attributes['html'] = html;
attachment.attributes['post_id'] = wp.media.view.settings.post.id;
//do what ever you like to use it
console.log(attachment.attributes);
console.log(attachment.attributes['attachment']);
console.log(attachment.attributes['html']);
});
});
//reset selection in popup, when open the popup
frame.on('open',function() {
var selection = frame.state('insert-image').get('selection');
//remove all the selection first
selection.each(function(image) {
var attachment = wp.media.attachment( image.attributes.id );
attachment.fetch();
selection.remove( attachment ? [ attachment ] : [] );
});
//add back current selection, in here let us assume you attach all the [id] to <div id="my_file_group_field">...<input type="hidden" id="file_1" .../>...<input type="hidden" id="file_2" .../>
jq("#my_file_group_field").find('input[type="hidden"]').each(function(){
var input_id = jq(this);
if( input_id.val() ){
attachment = wp.media.attachment( input_id.val() );
attachment.fetch();
selection.add( attachment ? [ attachment ] : [] );
}
});
});
//now open the popup
frame.open();

我想添加到ZAC的选项4，因为当我使用他的代码时，图像src =“”丢失了。
这是修复
if ( 'image' === obj_attachment.type ) {
html = wp.media.string.image( display );
_.each({
align: 'align',
size: 'image-size',
alt: 'image_alt'
}, function( option, prop ) {
if ( display[ prop ] )
options[ option ] = display[ prop ];
});
html = wp.media.string.image( display, obj_attachment );
}

这样您就可以使用自定义标题和按钮以及右侧栏调用新媒体上传器。
var custom_uploader;
jQuery('#fileform').on('click','.select-files', function(e) {
var button = jQuery(this);
custom_uploader = wp.media.frames.file_frame = wp.media({
title: 'Choose File',
library: {
author: userSettings.uid // specific user-posted attachment
},
button: {
text: 'Choose File'
},
multiple: false
});
//When a file is selected, grab the URL and set it as the text field's value
custom_uploader.on('select', function() {
attachment = custom_uploader.state().get('selection').first().toJSON();
console.log(attachment.url);
console.log(attachment.id); // use them the way you want
});
//Open the uploader dialog
// Set post id
wp.media.model.settings.post.id = jQuery('#post_ID').val();
custom_uploader.open();
});
