Today I needed to add a class to a Drupal 7 region and found the lovely template_preprocess_region() function to do the dirty work for me. With this function, you can easily add any class to your regions with the code below.
In a nutshell, you find the region you want to add the class to and then append your class onto the end of the classes_array variable.
I'm currently building a website that has a three columned layout. The left most column contains the navigation elements, the center column contains the body, and the right side column contains supporting text for the article. So I created three block regions in my theme: left_sidebar, content, and right_sidebar. The problem I ran into was that the text in the right side column was different for every node. Having the user create a separate block for each node seemed very inefficient.
This is a list of some of the more unique, excellent photo galleries I've come across.
Full screen, would be good for a touch screen interface:

Today I tried to ssh into a production server of ours and I began receiving this error message:
ssh_exchange_identification: Connection closed by remote host
Some thoughts for setting up a high performance Drupal stack:
Today I needed to change the format of a taxonomy term exposed filter to display the vocabulary hierarchy in groups instead of the normal '-Item', '--Sub-Item' format (see the before and after photos below).

Today I needed to add the html character "»" to a Drupal 7 form value. The first thing I did was alter the form and add the » character to the end of the submit button's value. Upon reloading the form, I noticed that instead of the character being displayed, the plaintext was displayed.
Today I ran into an issue of needing to programmatically remove file attachments from a node. To accomplish this I referred to the upload_nodeapi() function and found the upload_save() function. After examining the code I found that upload_save looks for the 'remove' parameter for the file object. If $file->remove exists, the file will be deleted from the database and file system. So by adding the 'remove' parameter to the files I needed removed before calling node_save() results in the files being removed from the node upon calling node_save(). Done!
Today I needed to import about 2000 user accounts into a new Drupal 7 database. To do this I decided to use the Feeds module which includes a Feeds Import module. Perfect! First, I went to the feeds admin interface and setup the import by mapping all of my fields to the .csv. Next, I opened Excel and generated my spreadsheet. Once that was completed I saved the spreadsheet as a .csv file and tried to import. The form returned with the following message "0 users created". WTF!
Today I had the pleasure of launching a new Drupal 7 website into the Aegir hosting platform. However, I quickly discovered that migrating a Drupal 6 site and a Drupal 7 site, while similar, are really quite different.
We are working on an Ubercart store running Drupal 7 and we needed to add the price per unit to the shopping cart page. I didn't see any options for enabling this in the store administration area so I began looking for some code to make this happen. I came across this post, http://pixeljets.com/blog/adding-price-field-ubercart-cart-page, which was close to what I needed, but I figured there was a theme function I could use instead of a custom module.
We have a site that is running the views slideshow module to display advertisement images. Recently a client asked us to prevent these advertisements from displaying only one item on the screen. In order to do this I began dissecting the views slideshow module code and I came across the template_preprocess_views_slideshow_cycle_main_frame() function. This function takes care of rendering the rows.
Today I needed to prevent a Drupal 6 website from getting indexed by the search engines. This would normally be a relatively easy task by having the robots.txt file disallow everything. The problem I ran into was that I was using Drupal's multisite feature and I needed to prevent a sub-domain from getting indexed while the main site continued getting indexed.
The other day I was tasked with redirecting the Drupal login form to the user account page. On any other form this would work by adding the #redirect tag to the form in a form alter function like this:
Today I needed to create an ajax powered form using Drupal 7, the caveat being that I needed one user action to perform multiple ajax actions to different sections of the form.
To begin, my form element with the ajax looks like this:
Today I was setting up a website that was using FlickrSync to pull images from Flickr. FlickrSync creates one node per image and uses Flickr's tags as taxonomy terms. Perfect.
I created a new Term view to pull all taxonomy terms associated to the 'Gallery' vocabulary I had created. The problem I ran into was that the view pulled ALL image nodes tagged with each gallery term. This was not what I was looking for. Instead, I wanted a list of each term and one image node, not all nodes.
I've recently been exposing a custom module's data to views 3 in Drupal 7. I copied the code from the uc_product module and for some reason, I couldn't get my views handlers to get registered with the system. Everything I tried would result in a broken/missing handler error. After scouring the online views documentation, http://views.doc.logrus.com, I finally found a line directing me to the advanced help module.
I'm building an e-commerce website and I decided to use Drupal 7 and Ubercart. During development I discovered that Ubercart 2's function, hook_cart_item, was no longer available to Drupal 7. This led me to the question:
Today I needed to take the parent menu item from my primary links and add it to the beginning of my secondary menu links. To begin, my menu structure looks like this:
The $main_menu variable will print a list item with:
When you click on the 'Primary 2' link the $secondary_menu variable will display:
Today I needed to create a view the filtered items by a range of prices. The prices for these nodes were stored in a CCK number field. After searching for an easy 'plug and play' method of doing this I quickly began writing my own code to accomplish this task. To summarize, I accomplished this by using the following functions:
