Module development and code questions

Hello,

For some nodes in my module, I'd like to add some data in the headers, like additional META tags, or some extra css styles.

I can't find a hook_html_head() function that would allow me to do so?

Can you confirm it's impossible, or is there a way I missed?

thanks.

Hello ,

I am having difficulties installing the patch taxonomy_all.patch on top of drupal 4.6.1
with both normal and enhanced privileges.

The patch has been uploaded to the root of my drupal installation.

From this directory when i issue the shell command
# patch < taxonomy_all.patch
File to patch : database/database.mysql

i receive the error
... can't find file to patch at input line 28

Similar problems are found for other patches for database/updates.inc and modules/taxonomy.module

I'm brand new to Drupal, after about 4 years of PostNuke.

One of the features that is super cool in Drupal, and one I would have written for my PostNuke sites if I were not making the switch is the drop down menus, and just to be sure we're on the same page, I mean the menu options you click on that then roll down more directly underneath.

I'm going through the docs now. I've been through modules developer guide, but maybe I missed how you make one module a 'sub-module' of another.

Can anyone point me in the right direction?

Thanks!

I wrote a flexinode field to easily manage a list of elements. You can choose to have an ordered or an unordered list; each element will have its own textfield.

Known issues: preview doesn't work (any idea?)

Here's the code, put it in

field_list.inc

in your flexinode directory.


<?php

function flexinode_field_list_name($field) {
return t('list');
}

function flexinode_field_list_form($field, &$node) {
$fieldname = 'flexinode_'. $field->field_id;

foreach ($node->$fieldname as $item) {
$item_fields .= form_textfield('', 'items][', $item, 60, 128);
}

$edit = $_POST['edit'];
if ($edit['items']) {
foreach ($edit['items'] as $item) {
$item_fields .= form_textfield('', 'items][', $item, 60, 128);
}
} else {
$item_fields .= form_textfield('', 'items][', '', 60, 128);
$item_fields .= form_textfield('', 'items][', '', 60, 128);
$item_fields .= form_textfield('', 'items][', '', 60, 128);
}
if($_POST['more']) {
$item_fields .= form_textfield('', 'items][', '', 60, 128);
$item_fields .= form_textfield('', 'items][', '', 60, 128);
$item_fields .= form_textfield('', 'items][', '', 60, 128);
}
$item_fields .= form_button(t('More fields'), 'more');

return form_group(t($field->label), $item_fields);
}

function flexinode_field_list_db_select($field) {
$fieldname = 'flexinode_'. $field->field_id;

Hello,

I'm very happy that Drupal is so quickly responding for new possibilities. The Google SiteMaps is very exciting possibility to increase number of visits.

But I can find to such modules on Drupal site.

I need an extra password widget in a module, and have run into a snag.

I've implemented hook_settings. The behavior I want is to check if the password and the confirm password fields don't match, I want the usual sort of "Passwords Must Match" error message to appear.

The problem is that system.module saves my password settings very early in the request processing. I can't use hook_validate because it won't get called for the _settings page. I can't do the validation in hook_settings because the system steps in long before that.

What's the recommended way to deal with this. I have a solution that works, but it's so fragile that it's pretty much guaranteed to get broken the next time system.module changes:

if(isset($_POST['edit']['my_password'])){
//looks like we are setting the site password.
//make sure the copies match so we do not get locked out.
$pw = $_POST['edit']['my_password'];
$pw_confirm = $_POST['edit']['my_password_confirm'];
if($pw != $pw_confirm){
form_set_error('my_password', t('Passwords must match!'));
//and we must unset some globals to fool the systems settings
//gremlin. TO DO: This is hinkey, and may break.
unset($_POST['edit']['my_password']);
unset($_POST['edit']['my_password_confirm']);
if($_POST['op'] == t('Save configuration')){
$_POST['op'] .= "--mod"; //to fool system.module
