当我单击帖子/页面上的添加媒体按钮时,我可以选择添加媒体.选择媒体后,单击“插入到帖子”,然后插入图像.但是,还有另一个选项,位于左侧边栏.我可以点击创建图库.图像选择过程是相同的,但是当我单击“创建新图库”时,它会转到一个新框架,允许我编辑图像的顺序.
第二个窗口就是我追求的目标.我从MetaBox调用框架,我已经成功地让它抓住单个或多个图像并将ID保存为字符串,以及将缩略图直接插入预览框.我找不到任何关于调用Gallery框架的信息.
我目前的代码如下：
jQuery('#fg_select').on('click',function(event){
event.preventDefault();
// If the media frame already exists,reopen it.
if ( file_frame ) {
file_frame.open();
return;
}
// Create the media frame.
file_frame = wp.media.frame = wp.media({
title: "Select Images For Gallery",button: {text: "Select",},library : { type : 'image'},multiple: true // Set to true to allow multiple files to be selected
});
file_frame.on('open',function() {
var selection = file_frame.state().get('selection');
ids = jQuery('#fg_Metadata').val().split(',');
ids.forEach(function(id) {
attachment = wp.media.attachment(id);
attachment.fetch();
selection.add( attachment ? [ attachment ] : [] );
});
});
file_frame.on('ready',function() {
// Here we can add a custom class to our media modal.
// .media-modal doesn't exists before the frame is
// completly initialised.
$( '.media-modal' ).addClass( 'no-sidebar' );
});
// When an image is selected,run a callback.
file_frame.on('select',function() {
var imageIDArray = [];
var imageHTML = '';
var MetadataString = '';
images = file_frame.state().get('selection');
images.each(function(image) {
imageIDArray.push(image.attributes.id);
imageHTML += '<li><button></button><img id="'+image.attributes.id+'" src="'+image.attributes.url+'"></li>';
});
MetadataString = imageIDArray.join(",");
if(MetadataString){
jQuery("#fg_Metadata").val(MetadataString);
jQuery("#featuredgallerydiv ul").html(imageHTML);
jQuery('#fg_select').text('Edit Selection');
jQuery('#fg_removeall').addClass('visible');
}
});
// Finally,open the modal
file_frame.open();
});
有任何想法吗？
编辑：
我已经把它直接调用了画廊,没有任何侧边栏等等.但是,它现在忽略了on(‘select’)调用.我猜画廊在选择图像时会发出不同的电话？
jQuery(document).ready(function($){
// Uploading files
var file_frame;
jQuery('#fg_select').on('click',reopen it.
if ( file_frame ) {
file_frame.open();
return;
}
// Create the media frame.
file_frame = wp.media.frame = wp.media({
frame: "post",state: "featured-gallery",button: {text: "Edit Image Order"},multiple: true
});
file_frame.states.add([
new wp.media.controller.Library({
id: 'featured-gallery',title: 'Select Images for Gallery',priority: 20,toolbar: 'main-gallery',filterable: 'uploaded',library: wp.media.query( file_frame.options.library ),multiple: file_frame.options.multiple ? 'reset' : false,editable: true,allowLocalEdits: true,displaySettings: true,displayUserSettings: true
}),]);
file_frame.on('open',');
if (!empty(ids)) {
ids.forEach(function(id) {
attachment = wp.media.attachment(id);
attachment.fetch();
selection.add( attachment ? [ attachment ] : [] );
});
}
});
file_frame.on('ready',function() {
// Here we can add a custom class to our media modal.
// .media-modal doesn't exists before the frame is
// completly initialised.
$( '.media-modal' ).addClass( 'no-sidebar' );
});
file_frame.on('change',function() {
// Here we can add a custom class to our media modal.
// .media-modal doesn't exists before the frame is
// completly initialised.
setTimeout(function(){
$('.media-menu a:first-child').text('← Edit Selection').addClass('button').addClass('button-large').addClass('button-primary');
},0);
});
// When an image is selected,run a callback.
file_frame.on('set',function() {
alert('test');
});
// Finally,open the modal
file_frame.open();
});

好的,所以我已经把所有东西都正确地解雇了.但我无法破译输出的图库代码.
// When an image is selected,run a callback.
file_frame.on('update',");
if (MetadataString) {
jQuery("#fg_Metadata").val(MetadataString);
jQuery("#featuredgallerydiv ul").html(imageHTML);
jQuery('#fg_select').text('Edit Selection');
jQuery('#fg_removeall').addClass('visible');
}
});
$imageArray或$imageHTML没有任何结果. $image是东西,它是[对象对象].
编辑3：如下面评论中所述,编辑2中的代码的主要问题是,当使用Gallery时,您必须调用“库”而不是“选择”.
// Uploading files
var file_frame;
jQuery('#fg_select').on('click',state: "gallery",multiple: true
});
file_frame.on('open',function() {
var selection = file_frame.state().get('selection');
var ids = jQuery('#fg_Metadata').val();
if (ids) {
idsArray = ids.split(',');
idsArray.forEach(function(id) {
attachment = wp.media.attachment(id);
attachment.fetch();
selection.add( attachment ? [ attachment ] : [] );
});
}
});
// When an image is selected,function() {
var imageIDArray = [];
var imageHTML = '';
var MetadataString = '';
images = file_frame.state().get('library');
images.each(function(attachment) {
imageIDArray.push(attachment.attributes.id);
imageHTML += '<li><button></button><img id="'+attachment.attributes.id+'" src="'+attachment.attributes.url+'"></li>';
});
MetadataString = imageIDArray.join(",");
if (MetadataString) {
jQuery("#fg_Metadata").val(MetadataString);
jQuery("#featuredgallerydiv ul").html(imageHTML);
jQuery('#fg_select').text('Edit Selection');
jQuery('#fg_removeall').addClass('visible');
}
});
// Finally,open the modal
file_frame.open();
});
我现在遇到的主要问题是我无法通过选择打开图库编辑.我可以把它打开,但没有选择图像.我在调查那个.我也在考虑重新开放而不是创建新视图并发送预选.如果我进入选择窗口,然后是订单窗口,但是单击X关闭,我可以重新打开订单窗口.所以应该有办法.

file_frame.on('open',function() {
var library = file_frame.state().get('library');
var ids = jQuery('#fg_perm_Metadata').val();
if (ids) {
idsArray = ids.split(',');
idsArray.forEach(function(id) {
attachment = wp.media.attachment(id);
attachment.fetch();
library.add( attachment ? [ attachment ] : [] );
});
}
});
这允许我直接重新打开图库编辑状态并预先选择图像.但是,当我直接打开这个状态时,我无法点击取消图库(返回图像选择状态).单击该按钮/链接只会关闭框架.我尝试预填充库和选择,但这也不起作用.以下是来自media-views.js,似乎是控制该按钮的内容.它不是将状态更改为特定状态,而是将其更改为先前的状态.由于我们直接打开gallery-edit,因此没有过去的状态.我想知道是否可以打开图库,然后打开,更改为图库编辑.立即执行以便用户看不到,但是它会将过去的状态带入系统.
galleryMenu: function( view ) {
var lastState = this.lastState(),prevIoUs = lastState && lastState.id,frame = this;
编辑5：
终于想通了.我根本无法完成上述任务,我不知道为什么.因此,可能有更好的方法来执行此操作,涉及该代码.如果是这样,我很想知道.
file_frame.on('open',function() {
var selection = file_frame.state().get('selection');
var library = file_frame.state('gallery-edit').get('library');
var ids = jQuery('#fg_perm_Metadata').val();
if (ids) {
idsArray = ids.split(',');
idsArray.forEach(function(id) {
attachment = wp.media.attachment(id);
attachment.fetch();
selection.add( attachment ? [ attachment ] : [] );
});
file_frame.setState('gallery-edit');
idsArray.forEach(function(id) {
attachment = wp.media.attachment(id);
attachment.fetch();
library.add( attachment ? [ attachment ] : [] );
});
}
});
最终编辑
我的代码现在完全正常工作,我很感激帮助！如果您想看到它的实际效果,请查看http://wordpress.org/plugins/featured-galleries/
我对WP比较陌生.事实上,我正在构建我的第一个WP主题,我和你一样陷入了同样的问题.感谢您的代码,我可以访问Gallery页面.幸运的是,我已经保存了图像.这是我的代码：
// when click Insert Gallery,run callback
wp_media_frame.on('update',function(){
var library = wp_media_frame.state().get('library');
var images = [];
var image_ids = [];
thumb_wraper.html('');
library.map( function( image ) {
image = image.toJSON();
images.push(image.url);
image_ids.push(image.id);
thumb_wraper.append('<img src="' + image.url + '" alt="" />');
});
});
我发现你应该得到’图书馆’而不是’选择’.
编辑：
我已经想出如何回到画廊编辑.这是我的完整代码：
$( '#btn_upload' ).on( 'click',function( event ) {
event.preventDefault();
var images = $( '#image_ids' ).val();
var gallery_state = images ? 'gallery-edit' : 'gallery-library';
// create new media frame
// You have to create new frame every time to control the Library state as well as selected images
var wp_media_frame = wp.media.frames.wp_media_frame = wp.media( {
title: 'My Gallery',// it has no effect but I really want to change the title
frame: "post",toolbar: 'main-gallery',state: gallery_state,library: {
type: 'image'
},multiple: true
} );
// when open media frame,add the selected image to Gallery
wp_media_frame.on( 'open',function() {
var images = $( '#image_ids' ).val();
if ( !images )
return;
var image_ids = images.split( ',' );
var library = wp_media_frame.state().get( 'library' );
image_ids.forEach( function( id ) {
attachment = wp.media.attachment( id );
attachment.fetch();
library.add( attachment ? [ attachment ] : [] );
} );
} );
// when click Insert Gallery,run callback
wp_media_frame.on( 'update',function() {
var thumb_wrapper = $( '#thumb-wrapper' );
thumb_wraper.html( '' );
var image_urls = [];
var image_ids = [];
var library = wp_media_frame.state().get( 'library' );
library.map( function( image ) {
image = image.toJSON();
image_urls.push( image.url );
image_ids.push( image.id );
thumb_wrapper.append( '<img src="' + image.url + '" alt="" />' );
} );
} );
} );
我想如果你重新打开现有的框架,它将始终保持初始状态,在你的情况下它是’画廊’.你必须每次都创建一个新的框架并检查是否有图像打开’gallery-edit’此外,我更喜欢’gallery-library’而不是’gallery’,因为我希望用户专注于我的画廊.
