Module development and code questions

File uploads (core module) are working fine. Uploading images with the image module only gives me the following error and a post without image: "Invalid argument supplied for foreach() in /export/www/students/projects/gamedevclub/modules/image/image.module on line 316."

Drupal 4.6
PHP Version 4.3.3
Apache
pgsql

I don't really understand what's going wrong. If only I had a more useful error to work with I might find out something more. I'm not good at php though.

If you need more info to answer my question, just let me know.

Hi.
I've created a module which displays a node instead of term-listing. If i call it without menu-modification all is ok. The "view" and "edit" tabs are displayed and teh breadcrumb is set correct.
But if i use "menu_set_location" to activate the corresponding menu-item the tabs aren't displayed anymore.
How can I set the active menu-item and display the tabs?
I tried to add

$items[] = array(
                 'path' => 'node/'. $nd->nid, 
			   'title' => t('view'), 
			   'callback' => 'node_page', 
			   'access' => node_access('view', $nd), 
			   'type' => MENU_CALLBACK
			   );
$items[] = array(
                 'path' => 'node/'. $nd->nid .'/view', 
			   'title' => t('view'), 
			   'access' => node_access('view', $nd), 
			   'type' => MENU_DEFAULT_LOCAL_TASK, 
			   'weight' => -10
			   );
$items[] = array(
                 'path' => 'node/'. $nd->nid .'/edit', 
		           'title' => t('edit'), 
			   'callback' => 'node_page', 
			   'access' => node_access('update', $nd), 
			   'weight' => 1, 
			   'type' => MENU_LOCAL_TASK
			   );

but it do not work ("access denied", even if "'access' => 1"). Changing "MENU_DEFAULT_LOCAL_TASK" to "MENU_LOCAL_TASK" displays the node but without tabs :-{

Any suggestions?

best regards,

I want to make a module that allows the user to selcct the background image of a node.

This will by done by selecting the image from one in image.module (maybe using image assist - or something like that) and then write it out to a style tag when the node is viewed.

I have never written a module before (apart from the getting started thing in the handbook) so can anyone give me some ideas of how to go about it? I was looking at nodewords to see if I could hack it about a bit, but it's a bit too complex for my needs.

Hello

I want to change the

Not that I've been able to find anything like this for any other site or message board software, but I'd really be interested in someday applying a dice roller to one of my sites, for the purpose of play-by-post roleplaying and such. If I'm missing something notable, could someone point it out to me? (..not limited to drupal.. I haven't been able to find a dice roller for anything!.. even something as common as phpbb..) If I knew how to go about it, I'd build it myself.. but I still have my hands slightly full getting used to customizing themes. For someone that is fully capable of envisioning and for that matter executing such a task, at very least (if you don't want to just go ahead and make it for me.. :D ) could you give me an idea of a difficulty level?

Some features I had imagined it could have..
_{~simple XdY format.. probably a string of text in brackets .. [roll=2d4]
~multiple dice in one roll .. [roll=1d4,2d6,8d100]
~have some sort a history table in the database or something? the rolls would be numbered in sequence.. perhaps a page could display the numbers, each of these numbers could then be linked to the article or post in which they were rolled.}

My followup question basically being, would the history feature be the downfall of an attempt at such a project? I MIGHT have a person or two to beg to do this for me, but I have to be able to convince them that it's not a waste of time first. ;)
