从Metabox调用WordPress库上传器/选择器

Question

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Insert Into Post,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.

这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,现在它忽略了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', 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({
        frame: "post",
        state: "featured-gallery",
        library : { type : 'image'},
        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', function() {
        var selection = file_frame.state().get('selection');
        ids = jQuery('#fg_metadata').val().split(',');
        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();

});

编辑2:

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', 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');
        }
    });

$ imageArray或$ imageHTML没有任何结果.$ image是某种东西,它是一个[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', 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({
        frame: "post",
        state: "gallery",
        library : { type : 'image'},
        button: {text: "Edit Image Order"},
        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, run a callback.
    file_frame.on('update', 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.我可以让它在那里打开,但没有选择图像.我在调查.我也在考虑重新开放而不是创建新视图并发送预选.如果我转到选择窗口,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.

根据以下答案中的代码,我已将预选代码更改为:

    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.我尝试预先填充库和选择,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.由于我们直接打开图库编辑,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/

WP对我来说比较新.事实上,我正在构建我的第一个WP主题,而且我和你一样困在同一个问题上.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'.你必须每次创建新的框架并检查是否有图像打开'gallery-edit'而且,我更喜欢'gallery-library'而不是'gallery',因为我希望用户专注于我的画廊.
