Retrieve cck node form array

pedro — Mon, 13 Dec 2010 17:48:59 -0500

The code bellow is to be used in any module. It requires cck module to be installed. The advantage of this code is that it allows you to use labels and field definitions done through the cck ui. It allowed me to build a custom form based in the fields previously defined, it saves time and keeps your custom form consistent with the content type form.

http://www.realityloop.com/blog/2009/05/24/fixing-gd-image-rotation-drup...

Thanks a lot for this really good quick fix to gd library in ubuntu.

I modified the first two lines:

deb http://packages.dotdeb.org stable all deb-src
deb http://packages.dotdeb.org stable all

I also noticed that the /etc/apt/sources.lst file in ubuntu is called sources.list

Remove or disable style sheets for single node on Drupal

pedro — Fri, 28 Aug 2009 18:09:57 -0400

I wanted to make one of the pages in my site look and feel completely different than the rest of the site. I wanted to use a different style sheet css file for this page and also didn't want to override all the existing styles.

I found a very good post about it on http://drupal.org/node/258756

Path redirect wildcard patch for path_redirect module

pedro — Wed, 22 Jul 2009 20:24:27 -0400

In order to make the path_redirect module handle redirections with wildcards, I created a patch for it. There wasn't a simple way to do wildcard redirections through the .htaccess file. Some times is important to make a wildcard drupal redirects.

The way wildcards work:
When you want to redirect a path like "/about/" to "/" then any path based in about will be redirected to "/" like "/about/something/" or "about/anything" will be redirected to "/".

Patched module is in the attachment. The attachment contains all the module files already patched.

Some handy tips to get the nodetrail module up and running quickly. Nodetrail is a great module that allows you set customs menu trails to any node.

When you install the node, you will get error messages, in order to fix them modify nodetrail.module file.

_nodetrail_recurse_crumbs($tree, $item, $crumbs);

Creating a node programmatically

Creating a node programmatically.

The best code snippet I found about this:

http://drupal.org/node/178506#comment-1590834

Some people say is better to use drupal_execute(), but on my experience I would recommend to use the snippet above.

Remove Page title based on node type

pedro — Fri, 05 Jun 2009 18:37:01 -0400

Quick and easy php snippet to have the page title not show on only certain node types.

Copy and paste the code below inside your template.php file.

<?php
function mythemename_preprocess_page(&$variables){
    if($node = menu_get_object()){
        if($node->type == 'my_node_type'){
            $variables['title'] = '';
        }
    }
}
?>

Works on Drupal 6

Setting up MENU_LOCAL_TASK for secondary tabs

pedro — Fri, 27 Mar 2009 16:02:53 -0400

How to create secondary local tasks or secondary tabs, also called sub tab (second level) menu items.

It was not clear to me why it was necessary to create a MENU_DEFAULT_LOCAL_TASK in every tab level. In order to tell drupal's menu system to show primary and secondary local tasks, there is a need to create a default local task every time. The default local task points to the same page as the parent item but has a path longer by one element.

Parent path:
'admin'

Default primary local task path:
'admin/home'

Embed VIEWS 2 into nodes

pedro — Wed, 25 Mar 2009 20:02:45 -0400

Very useful lines of code to embed "Views 2" views into your nodes.

Works almost as the old

<?php
$view = views_get_view('views_name');
print (views_build_view('embed', &$view, array(), $view->use_pager, $view->nodes_per_block)); 
?>

in Drupal 5 but for Drupal 6. This is also a way to embed views programatically into your pages and nodes.

The following lines of code will load a view and print the display.

Create list of links to taxonomy terms

pedro — Sat, 07 Mar 2009 19:43:40 -0500

This piece of code is to generate a menu or list of links to taxonomy pages. I used it inside a block. I created a view that shows all items under certain taxonomy term.

It is basically a taxonomy menu but you can customized an place it anywhere.
