Using imagecache with the Image or Embedded Media Field modules

Submitted by madmatter23 on Mon, 09/12/2011 - 09:49

Actually, there is a way to use imagecache presets with the image module without patches. It involves creating a View that manually applies the imagecache preset to the image field (not imagefield). You'll need views customfield.

Create a view and add the relationships "Image:File" and "Image:Node." Then add fields "File:path," "Node->title," and "Customfield: PHP Code." Add this to your php customfield script:

Add address field to Signup form, save to Content Profile

Submitted by madmatter23 on Fri, 09/02/2011 - 17:22

Alright, so this a bit nuanced, but I thought that I'd share it anyway. Maybe this snippet will help someone somewhere.

Scenario

I'm using the Signup module to permit users to signup for events, but I'd like them to be able to enter more than the standard name and phone number. I'd like my users to be able to provide their address.

Beyond that, if the user has already provided their address on their user profile (generated using Content Profile and the Location CCK module), then I'd like the fields to prepopulate.

Furthermore (we're getting crazy here), if they enter a new address on the signup form, I'd like them to be able to save that address to their profile.

Whoa!

Actually, with the power of the Forms API, this becomes an easy task.

Drupal: dealing with nested children that share their parent's path

Submitted by madmatter23 on Wed, 08/24/2011 - 10:21

Let's say that you'd like to create a nested menu in which one of the children links to the same path as its parent. Something like:

  •  people/friends
    • people/friends
    • people/family
    • people/neighbors

This works in theory-- the menu items will take you to the correct page. But if you're relying on Drupal to correctly set the active trail and expand the correct sub menus, you'll have to use a bit of a workaround. You're basically going to create dummy nodes that will redirect to the desired page rather than creating two menu links that have the exact same path. The parent (in menu) will redirect to the child's node.

Drupal: Add body classes based on user permissions

Submitted by madmatter23 on Thu, 08/18/2011 - 09:17

This one is a little bit more esoteric. I found the need change the page style (via CSS) based on whether the current user had permission to update the current node. Drupal preprocess_page to the rescue!

Just add this snippet to the yourTheme_preprocess_page function in your template.php file. It will add body classes (e.g., user-node-update, user-node-delete) to your page depending on the current user's permission to access the node being viewed.

Drupal: Add current user's role to body classes

Submitted by madmatter23 on Thu, 08/18/2011 - 08:49

If you'd like to change your site's appearance based on the current user's role, you can easily add the current user's role to the $body_classes array.

Just add this snippet to the yourTheme_preprocess_page function in your template.php file.

Escape Views' replacement patterns

Submitted by madmatter23 on Wed, 08/17/2011 - 17:25

Views replacement patterns are great, but they take up valuable variable real-estate. If you need to literally output "[nid]" rather than the value of its corresponding replacement pattern, you might start hitting your head against the wall.

I found this issue to be particularly annoying when using the Prepopulate module, which required CCK field names (with bracketed arrays) to a URL.

Never fear! Rather than using "[nid]" in your views text, try using percent encoding rather than literal brackets. The result would be:

%5Bnid%5D

Using percent encoding with stop views from replacing the replacement pattern with a dynamic value.

Add a Drupal template suggestion for Panels: page-panel.tpl.php

Submitted by madmatter23 on Mon, 08/15/2011 - 14:45

Drupal has a standard array of template suggestions that let you specify which TPL file should be used according to node type, node id, etc. However, there is no default template suggestion for pages generated by Panels.

You can easily fix that by adding a little snippet to your template.php files' preprocess_page() function.

Link to search page with advanced search fieldset expanded!

Submitted by madmatter23 on Thu, 08/11/2011 - 13:55

Create the link:

<a href="/search#advanced-search" class="advanced-search">Advanced Search</a>

Or you could even add it to the search box with jQuery (I'm adding it to a Custom Search block here):

Downgrading from Views 6.x-3.x-dev to 6.x-2.x

Submitted by madmatter23 on Wed, 08/10/2011 - 13:49

You may notice that after downgrading, you receive and error like:

Unknown column 'view_php' in 'field list' query:..sites/all/modules/views/includes/view.inc on line 1722.

If so, backup your database and then run this mySQL query:

Creating a dynamic menu link in Drupal

Submitted by madmatter23 on Mon, 08/08/2011 - 14:43

Sometimes you'll need to create a menu link that is different for each user that views it. The simplest way to do this is to create a small custom module that will add the menu link and generate a dynamic URL.

In my case, I wanted a link title 'My Company' that would redirect the user to their own Organic Group.

What to do
