[Drupal] Simple steps of building a module theme

1. Scene of building a theme.

/**
* Implementation of hook_block().
*/
function mymodule_block($op = 'list',$delta = 0, $edit = array()) {
  switch ($op) {
    case 'list':
      $blocks[0]['info'] = t('my testmodule');
      return $blocks;
    case 'view':
      $content = theme('mymodule_get_sth','David Lee', 'David Lee 2.0');
      $blocks['subject'] = t('Just atest');
      $blocks['content'] = $content;
      return $blocks;
  }
}

 

 

2. Build a function: hook_theme()

function mymodule_theme() {
  return array(
    'mymodule_get_sth' => array(
    'arguments' => array('arg_1' =>NULL, 'arg_2' => NULL),
    ),
  );
}

 

3. Build a function: theme_hook()

function theme_mymodule_get_sth($arg_1,$arg_2) {
  return '<divclass=”mymodule_theme”>'.$arg_1.' and '.$arg_2.'</div>';
}
