While writing the security component for Views Bulk Operations, I needed to create a permission for the execution of each action declared in the system. This would allow the admin to decide which user groups would be able to execute which actions.Read more
Google Spreadsheets are cool, but their problem is that they are hosted at Google instead of in your intranet portal. That means that they don't integrate easily with your other Web documents, in terms of classification, indexing, permissions, etc. The API provided by Google does help there, it's true. But what about adding new features? Google Docs simply isn't open source, and therefore is not ideal.Read more
In Drupal, can you modify the author of all nodes of type 'Story' whose title contains the word 'News:' to be user 'editor', without going through each node manually (or programmatically) ?
Before Views Bulk Operations (VBO for friends), you couldn't.
VBO builds upon existing modules and APIs to perform the useful function of mass-editing nodes, users, comments, or any other Drupal object. It reuses the incredibly powerful query builder [Views][] to list the nodes of interest, and it reuses the [Actions API][] to allow users to apply operations upon all selected nodes at once.Read more
What happens if you need to open a file with fopen, but find that your function can exit at multiple points? It is tedious and error-prone to call fclose at each exit point. Alternatively, you could re-structure your code to only exit at the bottom, thereby calling fclose only once, but you would end up with many nested blocks that hamper readibility and are generally considered bad programming style.Read more
Red Hat released an interesting map of open source activity worldwide. I was happy to find that Egypt is ranked among FOSS contributors, along with Jordan, Tunisia, and a few other Arab countries. Here at OpenCraft we are proud to be part of the companies that put Egypt on this map. At a rank of 58 (out of 75), there's only room to grow!
I recently came across an interesting bug that I thought to share with you PHP/Drupal heads.Read more
Using the CCK + Views platform, we can replicate the traditional ER (Entity-Relationship) framework into a rapid application development environment that minimizes procedural and SQL programming by replacing most of it with "Visual ER programming": a way to specify data model and behaviour in terms of SQL-like abstractions directly inside the runtime Drupal environment - and reaping the benefits of incremental, always functional output.Read more
The beginning of a new year is always a busy time. I hope it started in
the right direction for all of you! This year, we have plans to enlarge
the scope of the OC TechSeminar, with a little help from our friends and
partners. More on that later, but for now we are happy to announce an
exciting topic that should be of interest to many of you.
PRESENTATION ABSTRACT
Speech recognition is the most natural human interface to work with
computers and mobiles, we will present a technology overview of existingRead more
This article applies to Ubuntu with Apache 2, MySQL 5 and PHP 5 installed from the package manager.
When you start using Drupal on Ubuntu, one of the first things to do is to enable clean urls. That page will first ask you to run the clean URL test, which will show you if the underlying Apache infrastructure is ready for this or not. It it's ready, clicking the test link should bring you back to the same page, but with the radiobuttons enabled. Otherwise, you will get a "page not found" error.Read more
Drupal uses jQuery for all its JavaScript work. This library defines the variable "$" as a shorthand for jQuery, to allow writing concise code. However, other JavaScript libraries such as script.aculo.us and prototype also use the same variable name, making it a problem to use them in Drupal!Read more
