Add a new widget to the dashboard. Note, this will add the widget to the bottom of the page. If you want to try to move it to the top, check out the Codex page about dashboard widgets
add_action('wp_dashboard_setup', 'add_custom_dash_boxes');
function add_custom_dash_boxes() {
wp_add_dashboard_widget(
'welcome_box',
__( 'Welcome', 'myplugin_textdomain' ),
'welcome_box_text'
);
}
function welcome_box_text() {
echo 'Custom welcome text here';
}
If you feel your dashboard is too cluttered, you can use this to remove any or all of the widgets
add_action( 'wp_dashboard_setup', 'remove_wp_dashboard_widgets' );
function remove_wp_dashboard_widgets() {
//Plugins
wp_unregister_sidebar_widget( 'dashboard_plugins' );
remove_meta_box('dashboard_plugins', 'dashboard', 'normal');
