Message In Drupal

It's easy to make message in drupal. If your form function is data_form($form, &$form_state), so your submit function is data_form_submit($form, &$form_state). What's the point? The point is that you add "_submit" on the for function for your submit function. Look this  code

// form function

function data_form( $form, &$form_state){

    // implement codes

}

// form submit function

function data_form_submit( $form, &$form_state){

    drupal_set_message( t('Your data has been saved successfully') );

}

Drupal Form

When you code for drupal form, it's rather feel complicated. But it's simple enough to build what you want.
The procedures are:
1. Build your hook_menu to call the page that contain the form. In the hook_menu implementation, you need supply at least
a. title
b. page callback - for form, this is default to drupal_get_form
c. page argument - the function name you write inside array. This function implements drupal form
d. access callback - set to TRUE so averyone can access it

2. Build your form function
a. Insert in the arguments of the function definition: $form and &$form_state
b. define what form elements you provide

The list of the form elements:
a. submit: '#type' => 'submit', '#value' => 'Save'
b. item - provide small description '#type' => 'item', '#title' => t('The description')
c. textfield: '#type' => 'textfield', '#title' => t('The title'),
For more info, see code repositories
