Module development and code questions

I'm currently wrapping up development on Gallerix v1.0, a full featured AJAX gallery for Drupal. Features include:

• Batch uploading.
• Grid album view.
• AJAX photo browsing, commenting, voting, and minor editing.
• Easily expandable widget engine.
• Adjustable resolutions, originals left untouched.
• Security features.
• And many other features...

Requirements

Hi,
where can i find documentation to make custom triggers?

I'm trying to make a link directly from the thumbnail to the original image in the image gallery module. I found where it gets the url for this in image_gallery.module on line 381.

My code looks like this:
$content .= '<h3>'. l($image->title, 'node/'. $image->nid . '?size=_original') .'</h3>';

I was wondering if someone can help me out on this one ...

i have a function that looks up the record id of a record in filemaker and makes changes to that record based on the returned record id ... i am using fx.php along with FileMaker Pro 8... the edit function basically changes the password stored on the database .. however, whenever this function is executed .. the password doesn't really change and the module then takes me to a page that is intended to be shown after the password is successfully reset .. any pointers on where i am erring ?

code:

<?php

function reset_password_submit($form_id, $form_values) {

$arrErrors = array();
$newPass = $form_values['password_new'];
$currentPass = $form_values['password_current'];

$memberrecid = reset_password_connect_to_fm("web");
$memberrecid->AddDBParam('people::userid', $user->name,'eq');
$memberrecid->AddDBParam('people::drupal_uid', $user->uid,'eq');
$memberrecidresult = $memberrecid->FMFind();
$recid = array_shift(explode('.',array_shift(array_keys($memberrecidresult['data'])))); // retreieving record id

$resetPassword = reset_password_connect_to_fm("web");
$resetPassword->AddDBParam('-recid',$recid);
$resetPassword->AddDBParam('people::password',$newPass);
$resetPassword->AddDBParam('ipeople::webxstatus','pending');

modify trip forms needs to ad new feilds nd values "how"

how to modify zipcode coupon etc all the things in the forms

what to do
go of a code change or any other modulke needed to change it

I have a fairly simple form with a multiple select and a date field and when I submit the form, both of the mentioned fields seem to give me the error "warning: htmlspecialchars() expects parameter 1 to be string, array given in /var/www/html/drupal/includes/bootstrap.inc on line 636."

I checked bootstrap.inc and the error is in check_plain(). The only way I found to not display the message is to add a check on the variable passed and was wondering if there was something I was doing wrong.

Thanks,
Craig
