从…起this Q&A, 我已经了解了全局变量$wp_meta_boxes. 另外还有删除默认元框的代码。

检查完变量后，这是我为删除所有仪表板小部件而编写的代码，including the ones added by plugins:

add_action(\'wp_dashboard_setup\', \'wpse_73561_remove_all_dashboard_meta_boxes\', 9999 );

function wpse_73561_remove_all_dashboard_meta_boxes()
{
    global $wp_meta_boxes;
    $wp_meta_boxes[\'dashboard\'][\'normal\'][\'core\'] = array();
    $wp_meta_boxes[\'dashboard\'][\'side\'][\'core\'] = array();
}

答案是force one column 作为屏幕选项from here:

add_filter( \'get_user_option_screen_layout_dashboard\', \'wpse_4552_one_column_layout\' );

function wpse_4552_one_column_layout( $cols ) {
    if( current_user_can( \'basic_contributor\' ) )
        return 1;
    return $cols;
}

<小时>This one 提供了隐藏屏幕选项和帮助选项卡的代码：

add_filter( \'contextual_help\', \'wpse_25034_remove_dashboard_help_tab\', 999, 3 );
add_filter( \'screen_options_show_screen\', \'wpse_25034_remove_help_tab\' );

function wpse_25034_remove_dashboard_help_tab( $old_help, $screen_id, $screen )
{
    if( \'dashboard\' != $screen->base )
        return $old_help;

    $screen->remove_help_tabs();
    return $old_help;
}

function wpse_25034_remove_help_tab( $visible )
{
    global $current_screen;
    if( \'dashboard\' == $current_screen->base )
        return false;
    return $visible;
}

好了，现在仪表板上几乎什么都没有了，接下来怎么办

一点CSShide 这个icon-index 和H2 title, 还有一些jQueryfill the void:

add_action( \'admin_head-index.php\', \'wpse_73561_dashboard_scripts\' );

function wpse_73561_dashboard_scripts() {
    ?>
        <style>#icon-index, .wrap h2 {display:none}</style>
        <script language="javascript" type="text/javascript">
            jQuery(document).ready(function($) {
                fillTheVoid(); // soon in StackOverflow 
            });
        </script>   
    <?php
}

更新

填充的空隙可在中找到StackOverflow.
Use that wpse_73561_dashboard_scripts 函数而不是此函数。
