Module development and code questions

Hello there!

I am attempting to write a module for drupal for the first time. I am working on putting together a basic skeleton of a module together. I have created the file, inserted it into the module directory, named it properly, and inserted the following code, and activated the module in an attempt to have the module return a test string when I goto http://www.mywebpage.com/wpiupdates - all it does is return an error along the lines of index.php has failed to open stream. Bad file descriptor.

my web site has been working fine - and still works fine after the module is activated via the admin - I believe the problem lays with my code. can someone help me to figure out what i am doing wrong?

Here is the code:

function wpiupdates_settings() {
// only administrators can access this module
if (!user_access("admin wpiupdates")) {
return message_access();
}
}

function wpiupdates_node($field) {
$info["name"] = t("wpi updates");
$info["description"] = t("WPI Update Module.");

return $info[$field];
}

function wpiupdates_link($type, $node=0) {
if (($type == "system")) {
// URL, page title, func called for page content, arg, 1 = don't disp menu
menu("wpiupdates", t("WPI Updates"), "wpiupdates_all", 1, 1);
}
}

function wpiupdates_form(&$node, &$help, &$error) {

$help = ("Enter the latest WPI update inside this form.");

I need to know more about xtemplate and how it adds information and parses it. I'm developing a page shell module and I need to modify xtemplate so that it renders the shells correctly.

Ideally I would like to create a new function(s) within xtemplate that parses my information. Then within the xtemplate.xtmpl file I could add a new subsitution tag for page shells, {shell}.

Can anyone point me in the right direction?

I wasn't able to figure this out so I modified the _page function so that the $content variable was wrapped in an "if" statement. The "if" statement checked the type of the node and if it was a shell then it rendered my shell content instead of the node content. This almost worked, however the _page function doesn't get the $node information passed to it. So I had to call the node information using node_load. This method prints my content, but it also generates a permissions error.

In addition to modifying the _page function. I also tried putting an if statement within the _node function which checked the type and then tried to add the shell information to the node. For example taxonomy is added to the node variable, and so is avatar. I tired to add shell to the node variable using assign() and parse() but I was unsuccessful. Does anyone know how to do this?

Thanks, - Strayhand

Does any one know how to make it so that I can set settings in my module settings bit, and then have the setting commited to database?#

thanks

Is there a list for the user->name and user->uid sort of varibles?

this is a more efficient version of archive_calendar_listing that is mysql-specific. it also displays the total post count for each month:

function archive_calendar_listing_mysql() {
  $cache = cache_get("archive:calendar:listing");
  if (!empty($cache)) {
    return $cache->data;
  }

  $months = array(1 => t("January"), 2 => t("February"), 3 => t("March"), 4 => t
("April"), 5 => t("May"), 6 => t("June"), 7 => t("July"), 8 => t("August"), 9 =>
 t("September"), 10 => t("October"), 11 => t("November"), 12 => t("December"));

  $sql = "
    SELECT SUBSTRING(FROM_UNIXTIME(created), 1, 7) as date, COUNT(*) as count
    FROM   {node}
    WHERE  status = 1
    GROUP  BY date DESC
  ";

  $count = variable_get("archive_months", 0);
  if ($count) {
    $sql .= " LIMIT $count";
  }

  $result = db_query($sql);

  while ($month = db_fetch_object($result)) { 
    list($y, $m) = explode('-', $month->date);
    $mname = $months[intval($m)];
    $items[] = l("$mname $y", "archive/$y/$m") . " (" . $month->count . ")";
  }
  $output = theme("item_list", $items); 

  cache_set("archive:calendar:listing", $output);

  return $output;
}

Hi All! I'm working on a new module intended for my Drupal 4.4.x system. So I thought I would follow the recommendations of using these hooks instead of _nodeapi. However, for some reason they are NOT being called. Any tips on how to diagnose / correct this problem are appreciated!
