我已经成功地向媒体上传器添加了一个自定义选项卡，但由于某些原因，它的布局不同-它不会加载包含所有其他选项卡的媒体上传器标题：

  add_filter(\'media_upload_tabs\', \'my_media_upload_tabs_filter\');

function my_media_upload_tabs_filter($tabs) {
        unset($tabs["type_url"]);
        unset($tabs[\'library\']);
        $newtab = array(\'ell_insert_gmap_tab\' => __(\'Google Map\',\'insertgmap\'));

        return array_merge($tabs,$newtab);
}

add_action(\'media_upload_ell_insert_gmap_tab\', \'media_upload_ell_gmap_tab\');

function media_upload_ell_gmap_tab() {
    return wp_iframe(\'media_upload_ell_gmap_form\', $errors );
}

function media_upload_ell_gmap_form() {
    ?>
    <h2>HTML Form</h2>

<?php
}
