Hide the "Created new forum XXX" message in Drupal

Question

Every time I create a new forum using the API, the message:

Created new forum blah blah

appears (status message).

Can I suppress it? maybe with a hook?

There is a module that creates a hook that you can use to alter messages. http://drupal.org/project/messages_alter

I think that it would work for your use case, however if you need something it doesn't offer or just want to roll your own option: A quick look at the module will give you ideas on how you can create your own implementation if you need it.

I honestly can't remember why we did it ourselves, instead of using the module, but here is some really simple example code.

/**
 * function to check the messages for certian things and alter or remove thme.
 * @param $messages - array containing the messages.
 */

function itrader_check_messages(&$messages){
  global $user;
  foreach($messages as &$display){
    foreach($display as $key => &$message){
    // this is where you'd put any logic for messages.
      if ($message == 'A validation e-mail has been sent to your e-mail address. In order to gain full access to the site, you will need to follow the instructions in that message.'){
        unset($display[$key]);
      }
      if (stristr($message, 'processed in about')){
        unset($display[$key]);
      }
    }
  }
  // we are unsetting any messages that have had all their members removed.
  // also we are making sure that the messages are indexed starting from 0
  foreach($messages as $key => &$display){
    $display = array_values($display);
    if (count($display) == 0){
       unset($messages[$key]);
     }
  }
  return $messages;
} 

Theme Function:

/**
 * Theme function to intercept messages and replace some with our own.
 */
function mytheme_status_messages($display = NULL) {
  $output = '';
  $all_messages = drupal_get_messages($display);
  itrader_check_messages($all_messages);
  foreach ($all_messages as $type => $messages) {
    $output .= "<div class=\"messages $type\">\n";
    if (count($messages) > 1) {
      $output .= " <ul>\n";
      foreach ($messages as $message) {
        $output .= '  <li>'. $message ."</li>\n";
      }
      $output .= " </ul>\n";
    }
    else {
      $output .= $messages[0];
    }
    $output .= "</div>\n";
  }
  return $output;
}
