Sometimes you find just the right resources that fulfill certain need and nothing much should be added to them, in those cases I will just collect them on this page and add short comment why is this so.

Omega 4 and Compiling Sass on Windows (how to install and make it work)

I know Sass and Less are major improvements in Css coding, but setting all this up is a drag. I was using Omega 4 and to style it we need to use Sass coding. There are enough resources out there, but they are often limited to some special use case scenario and as there are many components to make it work you will have problems when trying to set it up. So after a day of work I finally pulled it off and made this Sass thing work and auto compile to Css.

Great RFP (Request for Proposal) for new Drupal Job board site

https://association.drupal.org/node/18998 I just really like that RFP (Request for Proposal) was done online and you can access all the documents on that link and see how professional RFP should be made and what project documentation should every project have (as many don't have).

No file found - get the file object in file upload validate function

I had a form without this "name" parametar, and without that parametar there is just no file object in validate function for file upload

$form['image']['file']= array(
'#name' => 'files[advert]',
'#type' => 'file',
'#title' => '

'.t('Add New Image').'

',
'#description' => t('Upload a file, allowed extensions: jpg, jpeg, png, gif'),
);

and then you can get it in validate function like below with 'advert'

function item_validate($form, &$form_state)
{

Tableselect Form API - How to delete/edit selected rows from tableselect

To delete/edit selected rows from tableselect and have something to work in in form_state you should add keys to your array in your form like:

$rows = array();
foreach($fullList as $line)
{
$rows[$line->category] = array(
'tid' => $line->category,
);
}

This way you will be able to easily retrieve values on your submit/delete handler on $form_state

foreach ($form_state['values']['table'] as $rows) {
$delete = db_delete('htb_if_categories')
->condition('category', $rows, '=')

Setting Sessions and Cookies

Setting a session in Drupal is easy, everything is set from the Drupal boostrap, all you need to do is to set it and get it. Like

$_SESSION['zip'] = $form_state['values']['zip_code'];
and latter you just get value on some page like
$view_filters['field_zip_range']['value'] = $_SESSION['zip'];

and it works. Just be careful of caching and varnish and similar things as they sometimes do not cooparate.

Session is set on server side.

For client side, you use cookies and set it like this

user_cookie_save(array('key'=>'value'));
print $_COOKIE['Drupal_visitor_key'];

View 3, alter filters programmatically

function custom_views_pre_view(&$view) {
if ($view->name === 'pricing') {
$view_filters = $view->display_handler->get_option('filters');
$view_filters['field_zip_range']['value'] = $_SESSION['zip_code'];

$overrides = array();
$overrides['filters'] = $view_filters;
foreach ($overrides as $option => $definition) {
$view->display_handler->override_option($option, $definition);
}
}
}

Views 3 query altering with hook_views_query_alter

You can alter views, alter queries and much more. Problem with documentation online is that is lacking some crucial information.

First, you should put your alter function in separate file, your_module.views.inc
as it is said here
https://api.drupal.org/api/views/views.api.php/function/hook_views_query...

What you also need to do is implement hook_views_api, it is said above that you don't have to but with lates views 3.0 it won't work if you don't do it, so you add this little line

function your_module_views_api() {
return array('api' => 3.0);
}

Modal form, CTools automodal and redirect

Currently I am using a https://drupal.org/project/ctools_automodal for my modal forms, that use CTools and its form dialogs for nice overlay forms (well not so nice, they look ugly as hell, but you can theme things :) ).

So there are some good tutorials how to setup modal forms and make you forms in overlay

WSOD or white screen of death and error reporting

Sometimes you will have a WSOD and nothing to show for. One simple solution to get what is a problem is to insert the following lines into the Drupal's index.php, that should set PHP to report all errors.

<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
?>

and you will probably see that some module is making a problem, so you can fix it or disable it.
