这是一条古老的线索，但对我来说仍然是相关的。我一直在摆弄并想出了在此处添加媒体选项卡的代码，也许有人想继续了解如何处理选项卡的内容？：）

add_action(\'admin_enqueue_scripts\', function(){
    wp_enqueue_script( \'my-media-tab\', plugin_dir_url( __FILE__ ) . \'/js/mytab.js\', array( \'jquery\' ), \'\', true );
});

var l10n = wp.media.view.l10n;
wp.media.view.MediaFrame.Select.prototype.browseRouter = function( routerView ) {
    routerView.set({
        upload: {
            text:     l10n.uploadFilesTitle,
            priority: 20
        },
        browse: {
            text:     l10n.mediaLibraryTitle,
            priority: 40
        },
        my_tab: {
            text:     "My tab",
            priority: 60
        }
    });
};

jQuery(document).ready(function($){
    if ( wp.media ) {
        wp.media.view.Modal.prototype.on( "open", function() {
            if($(\'body\').find(\'.media-modal-content .media-router a.media-menu-item.active\')[0].innerText == "My tab")
                doMyTabContent();
        });
        $(wp.media).on(\'click\', \'.media-router a.media-menu-item\', function(e){
            if(e.target.innerText == "My tab")
                doMyTabContent();
        });
    }
});

function doMyTabContent() {
    var html = \'<div class="myTabContent">\';
    //My tab content here
    html += \'</div>\';
    $(\'body .media-modal-content .media-frame-content\')[0].innerHTML = html;
}

根据WordPressCodex 您可以在media uploader中添加自定义选项卡，如下所示：

// add the tab
add_filter(\'media_upload_tabs\', \'my_upload_tab\');
function my_upload_tab($tabs) {
    $tabs[\'mytabname\'] = "My Tab Name";
    return $tabs;
}

// call the new tab with wp_iframe
add_action(\'media_upload_mytabname\', \'add_my_new_form\');
function add_my_new_form() {
    wp_iframe( \'my_new_form\' );
}

// the tab content
function my_new_form() {
    echo media_upload_header(); // This function is used for print media uploader headers etc.
    echo \'<p>Example HTML content goes here.</p>\';
}

   function axcoto_genify_media_menu($tabs) {
            $newtab = array(\'genify\'  => __(\'Axcoto Genify\', \'axcotogenify\'));
            return array_merge($tabs, $newtab);
            }
            add_filter(\'media_upload_tabs\', \'axcoto_genify_media_menu\');

           array(\'genify\' => __(\'Axcoto Genify\', \'axcotogenify\'));


        function axcoto_genify_media_process() {
        media_upload_header();
        echo \'hello\';
        }
        function axcoto_genify_media_menu_handle() {
        return wp_iframe( \'axcoto_genify_media_process\');
        }



 if ( ( is_array( $content_func ) && ! empty( $content_func[1] ) && 0 === strpos( (string) $content_func[1], \'media\' ) ) || 0 === strpos( $content_func, \'media\' ) )
        wp_enqueue_style( \'media\' );
