Module development and code questions

Iam updating the flexiblock for 4.7 here. But I get this error:

Fatal error: Call to undefined function form_checkbox() in www.myserver.tld\cvs\modules\flexiblock.module on line 141

I've red about the form api, but i dont understand much of it to be quite honest...so all help would be most appreciated!

These are the 6 lines I need to convert:

in 4.7 HEAD
My simple module, copied from page.module and somewhat modified behaves as follows:
on any menu or home url, the main drupal code seems to be running through my module's hook_help functions twice. The first time all is well, $section has appropriate contents and my embedded print statements appear before the header on screen. But then the hook_help module is called again, with "" in $section, and my embedded print statemenst also appears on screen before the header is printed. The return text shows up in the middle of the page node.

here is my hook_help:

function iquote_help($section) {
print " strt of help hook... section = $section" ;
  switch ($section) {
    case 'admin/help#iquote':
print "iquote admin help hook... section = $section" ;
      $output = t('The iquote module admin help page. ') ;
      return $output;
    case 'admin/modules#description':
print " iquote adminmodulesdeschelp hook... section = $section" ;
      return t('Enables the creation of ....');
    case 'node/add#iquote':
print " iquote nodeadd help hook... section = $section" ;
      return t('node add help text.');
default:
print " iquote no section " ;
      return t('nada babeeeeeee.');

  }
}

and hook_menu:

function iquote_menu($may_cache) {
$items = array();
//_vd("mixed var", "start iquote_menu");
print " strt of menu hook..." ;

I have problems with the feedback module. The spammers can use the mail server in the Drupal webpage with the following line in the body of the message (in feedback form):

This seems like it should be pretty easy but my knowledge of php is so very limited, so here goes...

I have a module that is basically adding one line to the end of blog nodes, which works fine in itself. But I need it to pull a specific profile field from the author of the node.

First, I need to define who the author of the node is, and then take a profile field based on that.

I could just use a nudge in the right direction, since everything I try seems to fail miserably.

Any help would be awsomeness.

REALLY ANNOYING that the forum posts dump your post cuz you added something it didn't like... but i'll try again...

=================

I am trying to have a module add a VAR so that my JS code can access it. I thought perhaps drupal_to_js sounded like the right thing - but it doesn't seem to do anything.

anyone know how to do this?

alternatively.. simply some way to add text string to < h e a d> would be useable as well.

if drupal_to_js is the right thing to use here; can some point me to an example?

i tried the obvious

Did the moderation queue module used to come standard?
