Two submit buttons in one form

Two submit buttons in one form::

Multiple Submit Buttons in a form-

We can use more than one submit button in a single form.
We can give each input a different value and keep the same name or different name:

#Same name Like::
<input type="submit" name="action" value="Update" />
<input type="submit" name="action" value="Delete" />

PHP Code:
if ($_POST['action'] == 'Update') {
    //action for update here
} else if ($_POST['action'] == 'Delete') {
    //action for delete
} else {
    //invalid action!
}



#Diffent Name like::

<input type="submit" name="update_button" value="Update" />
<input type="submit" name="delete_button" value="Delete" />

PHP Code:

if (isset($_POST['update_button'])) {
    //update action
} else if (isset($_POST['delete_button'])) {
    //delete action
} else {
    //no button pressed

}
