Add Content to Ubercart Checkout Panes

By Jimmy Bonney | August 16, 2011

While working on the online store of D-Sight, it was necessary to include a link back to the cart when a user is on the checkout page. It is possible to click on the Cancel button but this is a bit counter-intuitive and one might not know whether the cart will remain or whether it will be emptied. Therefore, two options have been considered:

  1. Change the Cancel button label to rename it “Back to cart” for instance
  2. Modify the cart pane in the checkout view to include additional information (such as a “Back to cart” link)

Getting Code to Display Properly With nanoc and HAML

By Jimmy Bonney | August 12, 2011

When I wrote the article about drupal and metadata, I needed to include some code snippets in order to illustrate what needed to be done. At the time, only nanoc, haml and sass were installed in my environment to generate this website. While I thought that it would be trivial to display code between pre tags, it turned out that I coudn’t get haml to display anything properly - even though I tried pretty much every combination (:preserve, whitespace preservation ~, …) in the haml-lang website.

Add Metadata to a Drupal Node

By Jimmy Bonney | August 12, 2011

While trying to ensure that a website created in Drupal was correctly verified with Google webmasters tools, I needed to add some metadata to the homepage of the website. Since this was a one shot only operation, it was not necessary to modify the full website template. Instead, in such cases, it can be done quite easily by adding the following bit of PHP code to the body of the home page and to ensure that the input format is set to PHP code.

<?php
    $meta = '<meta name="google-site-verification" content="ABCDEFGHWy6OxJzyJkzWGq4Um7FXYZTUVW" />';
    drupal_set_html_head($meta);
?>

The function drupal_set_html_head is fully documented in Drupal API. Put simply, it allows to add code in the head tag of the HTML output.


Encrypt Email Address

By Jimmy Bonney | July 9, 2011

An easy way to limit (or fully avoid) spamming is to encrypt the email addresses that appear on your website. In order to do that, services exist and help you convert your email address (or even the complete mailto: link) into hexadecimal entities.

The following two services can be used for such a purpose:

A lot of others services are obviously available and a simple search on Google for “encrypt email” will provide you a lot of results but I have been very happy with those two so far and they have been used with success on D-Sight website as well as on this website.


Drupal Inline Popup Reference Field

By Jimmy Bonney | October 7, 2009

It seems that I am spending some time learning Drupal so the content of this post may defer from the editorial line a bit but as usual, I hope it may help someone.

The current drupal installation I am working with has CCK and Popups: Add and Reference (let’s call it PAR for future (shorter) references) modules. Unfortunately, by default the links added by PAR are in a new div tag below the input fields which increase the length of the form quite a bit as you can see below.

PAR - Links under input field

What I am proposing here is a way to put the PAR links inline with the input field. I am quite a beginner with Drupal so the method may not be really clean or fail proof and your comments about any easier way of doing it are welcomed. The result looks like the screenshot below.

Drupal Private Download Folder

By Jimmy Bonney | August 26, 2009

Still working with Drupal and still learning a lot… The challenge I was facing was to let users upload files to a specific folder but to restrict access to that file so that it cannot be downloaded by anybody simply by giving the file path (private download). Therefore, users are allowed to post content but not access it (otherwise nothing prevent them to access files from other users in the folders).

Fortunately - as often with Drupal - there are already solutions on the web:

  1. Mixing private and public downloads in Drupal 6
  2. Restrict specific folders from public download (via .htaccess)

To summarize, I mixed the two solutions given here above, because I had a problem when using only solution 1 (my drupal site is not at the root of the website but in a subfolder). Therefore I used method 2 and edited the .htaccess file at the root of the website in order to add the following line somewhere in the block delimited by <IfModule mod_rewrite.c>...</IfModule>:

RewriteRule ^sites\/default\/files\/(protected_download_dir\/.*)$ index.php?q=system/files/$1

Share Firefox Profiles Between Computers

By Jimmy Bonney | July 7, 2009

It is no secret, it is easy to share a firefox profile. I am running a dual boot Linux / Windows and was therefore interested to share my Firefox profile between the two. But in the process, I actually became interested to be able to access that profile from my work computer. After all, there are already extensions to store bookmarks remotely so why not do the same with the complete profile.

This is the reason why I decided to create a new profile on my Dropbox. That way, the profile is stored remotely and synchronized in real-time between my work computer and my personal computer (both Linux and Windows).

Creating a new profile can be done in two ways. The first is by using the graphical interface and the second is by modifying the profiles.ini file directly. I will present both.

Install Linux Mint on Lenovo X200

By Jimmy Bonney | July 6, 2009

In my previous post, I detailed how I partitioned the drive of the X200 in order to install Linux. I will now give a few words about the installation process of Linux Mint 7. The focus of this post is set on how to keep your boot loader as it is and allow a dual boot Windows/Linux from the Windows boot loader.

There are only a few things that I changed from the default installation. The first one concerns the partitioning. Since the drive is already partitioned, it is necessary to tell the installer which partitions to use for what. From the picture below, you can easily see which partitions are used and where they are mounted.

Partitioning Lenovo X200 to Install Linux

By Jimmy Bonney | July 6, 2009

I wanted to install Linux on my computer (Lenovo X200) but I was a bit afraid to mess with the partition table due to the fact that there is a hidden Restore & Recovery partition available at boot up when one press on the ThinkVantage button.

I did want to keep Windows available as there are a few programs that can come handy and I didn’t want to mess with the default behavior of the computer (understand that the ThinkVantage button should still work, that windows should still be accessible and that I can basically still use the laptop the way I used to do :-)).

I will explain in the following paragraphs how to reformat the drive using open source tools and how I created the new partitions for the X200.

Create SOCKS Proxy to Bypass Censorship

By Jimmy Bonney | June 17, 2009

Using the method described in my previous article, you can easily see the benefit to bypass censorship. By using the set up previously described, you can encrypt all your traffic through the proxy and therefore appear as if you are only having one long SSH connection.

But in addition, it can be a good idea to configure Firefox to use the proxy to resolve the DNS requests (in case the DNS server you are using are “filtered”). To do so, type “about:config” in the adress bar and change the setting of network.proxy.socks_remote_dns from false to true as shown below.
