您可以致电：

add_meta_box( $widget_id, $widget_name, $callback, $screen->id, $location, $priority );

其中，通过以下方式获得屏幕ID：

$screen = get_current_screen();

然后显示每个位置，例如：

do_meta_boxes( $screen->id, \'column3\', \'\' );

以下是显示仪表板的仪表板功能：

function wp_dashboard() {
    global $screen_layout_columns;

    $screen = get_current_screen();

    $hide2 = $hide3 = $hide4 = \'\';
    switch ( $screen_layout_columns ) {
        case 4:
            $width = \'width:24.5%;\';
            break;
        case 3:
            $width = \'width:32.67%;\';
            $hide4 = \'display:none;\';
            break;
        case 2:
            $width = \'width:49%;\';
            $hide3 = $hide4 = \'display:none;\';
            break;
        default:
            $width = \'width:98%;\';
            $hide2 = $hide3 = $hide4 = \'display:none;\';
    }
?>
<div id="dashboard-widgets" class="metabox-holder">
<?php
    echo "\\t<div class=\'postbox-container\' style=\'$width\'>\\n";
    do_meta_boxes( $screen->id, \'normal\', \'\' );

    echo "\\t</div><div class=\'postbox-container\' style=\'{$hide2}$width\'>\\n";
    do_meta_boxes( $screen->id, \'side\', \'\' );

    echo "\\t</div><div class=\'postbox-container\' style=\'{$hide3}$width\'>\\n";
    do_meta_boxes( $screen->id, \'column3\', \'\' );

    echo "\\t</div><div class=\'postbox-container\' style=\'{$hide4}$width\'>\\n";
    do_meta_boxes( $screen->id, \'column4\', \'\' );
?>
</div></div>

<form style="display:none" method="get" action="">
    <p>
<?php
    wp_nonce_field( \'closedpostboxes\', \'closedpostboxesnonce\', false );
    wp_nonce_field( \'meta-box-order\', \'meta-box-order-nonce\', false );
