Module development and code questions

"Invalid argument supplied for foreach() in .../drupal/modules/taxonomy_jsmenu.module on line 51"

Can anybody tell me what this means?
I have some taxonomies set up and when I enable the taxonomy_jsmenu module I get this message. at the top of the screen, and no menu blocks are created. Does anybody know what I'm not doing? This module seems to have worked for everybody else!

line 51 reads foreach ($tree as $term) {

I am new to this drupal .I want to write a course module .I want to write some test modules before actually writing the module.I looked at documentation and found some
sample code to write a node module .I tried that but it did not work .I kept the following lines if code in a file called diary.module . I enabled the module in site configuration /modules .But I did not find any node on the website .I did not find any blocks .

I am building an external php script that interfaces with drupal. I am looking to maintain some of the drupal functionality - mainly the blocks from my theme. presently I am including common.inc & theme.inc - I am looking to display the blocks (logon & navigation specifically)

I have a statement in my code: theme_blocks("all"); and a return; at the end of my script. If a user is not logged on it will display the logon block, but if a user is already logged in, it doesn't display anything.

Hi,

I can add a link to a node, but the delimiters are getting messed up. I'm getting this:

» add new comment | MY LINK | | read more | administer

Which cant be right of course....

Here's what im using to do this:

function emailpage_link($type="node", $node=0, $main=0) {
$links[] = l(t('email this page'), "emailpage", array('title' => t('Send this page to a friend!'), 'class' => 'read-more'));
$links[]=menu("emailpage", t("email this page"), "emailpage_page", 0, 0);
return $links;
}

Hi,

I am going to write a module that instead of providing a block, as outlined here: http://drupal.org/book/view/4721 will provide an extra link to a page where the 'comment' and 'administer' and 'read more' links appear.

It's an 'email this story' thingy.

So, my question is: Where/what/how on getting that link instead of a block?

Many thanks

Nick
