Module development and code questions

I am working on a couple of modules and am using the core modules as an example style. But it would be nice to know if there is a style guide for modules that the Drupal community prefers. A search found too many hits to be useful. Based on existing modules and some forum comments I am guessing something like:

Hello,

I am trying to modify event.module (the calendar module) so that the Upcoming events block will only list an event if its audience includes the group that the user is currently viewing. I think that I can get this behavior by modifying the following function from event.module so that the assignment statement in the body of the while loop is only executed if the audience of $node (an event) includes the group that the user is currently viewing (the group with node id equal to arg(1)). But I'm not sure how to perform that test.

Has anyone tweaked flexinode to enable exporting of each flexinode type's data into excel or CSV, and also export the data w/ it's associated taxonomy vocab and terms?

I see how the contact module does this, but it does not export w/ corresponding taxonomy data. Any ideas?

Hi all,

I've been stucked with this for two weeks now.

This block of code does exactly what I want

<?php
  $random_nid = 42;
  $tids = array_keys(taxonomy_node_get_terms($random_nid));
  $result = taxonomy_select_nodes($tids);
  $output .= '<p>';
  $output .= taxonomy_render_nodes($result);
  $output .= '</p>';
  return $output;
?>

but when I use it in my module below, the taxonomy_render_nodes function fails with "memory exausted".
I've tried to increase the memory, but it didn't help.

Any Ideas ?

function committee_view(&$node, $teaser = FALSE, $page = FALSE) {
  $content = theme('committee',$node);
  $node->body = $content;
  return $node; 
}

function theme_committee($node) {
  $output ='';

  $header = array(t("Chair"),t("Secretary"),t('Frequency'),t('Rep/Delegate'));

  $rep = ''; 
  $rows[0] = array($node->chair,$node->secretary,$node->frequency,$rep);

  $output .= theme('table', $header, $rows);

  $output .= '<div class="content">';
  $output .= l(t("Go to the Committee Homepage for more Information"), "$node->homepage");
  $output .= "<br/><br/>";
  $output .= t("$node->body\n");
  $output .= '</div>';

  $tids = array_keys(taxonomy_node_get_terms($node->nid));
  $result = taxonomy_select_nodes($tids);
  $output .= '<p>';
  $output .= taxonomy_render_nodes($result);
  $output .= '</p>';

  return $output;
}

I'm aware some of them wont work but off hand anyone know which ones do work out of the modules that haven't be updated specifically to the new 4.6.1? I'm thinking of using the cafepress one but unsure if it will bork if I attempt to use it.
