Code to escape WordPress strings for Google Analytics.

Code to escape WordPress strings for Google Analytics. :

A Quick Template Tag to create Google Analytics Event Tracking on links. Built on behalf of CFO Publishing. 

I don’t really see anyone doing this in a way that guarantees completely safe strings for event tracking or custom variables. I think this way does, especially for strings with quote marks in them, which could be nasty. Thoughts?

Etherpad Lite AMI – alpha setup for folks interested in Participad

Etherpad Lite AMI – alpha setup for folks interested in Participad:

Working on setting up an AMI for people to run Etherpad Lite. This one is built using the BitNami node.js install. 

Right now, this is the most basic possible install. All that’s been done is everything has been installed and the correct ports open. You still have to start it from the command line and no configuration or security options have been enabled. However, I figure it is a good start. 

If you pop this up and have a good configuration set up, pass it along by sharing your AMI as well. 

Once running, the Etherpad Lite install is available from yourAMIurl:9001/.

This set up will one day be a lot easier to use and is currently still quite technical, but is, at least, less technical to set up than before and is a great alternative for those who want to run Participad, but don’t have the command line access needed to set up Etherpad Lite on a shared server. 

Stand by for more updates on this AMI, with better configuration.

User Roles, Capabilities, and control: How to allow WordPress users to control access to parts of their site without diving into the code.

April 17 Comments Off Category: Code, Feed, Tumblr, Wordpress

So, earlier today I discovered that there is not an easy way to allow users to control user access to various parts of the back end. As far as I can tell, the functions just don’t exist in the core and the two parts WordPress cares about.

The problem is that WordPress controls access to its various components (and to any developer-added components) using capabilities. The capability system is pretty cool, but in order to make it as customizable as possible, they are not tied to specific user roles. 

This sounds like a good idea, until you want to create a way for a site’s administrators to give specific user roles the ability to access (or not access) parts of a site or plugin. 

Your average user has no interest in checking the user/capability chart every time they want to switch a user’s access. It would be ridiculous to ask them to do so. But just setting up an option for administrators to select user levels is useless to me as a developer, because all the actual functionality resides in setting capabilities matched to things like menus. 

So, I need to be able to do a few things in order to make the two ends meet here. 

  1. I need to be able to find out what the user level is based on the capability. 
  2. I need to be able to identify a capability that ‘defines’ a user role, that  being one that a user role can do, but that no lower user roles can do. 

So, to do all that, I set up three functions.

The first allows you to get just a list of capabilities, with each capability having an array of the user roles that can use it. As an added bonus, it will also allow you to get just a specific capability and its array. 

The second allows you to get a role by capability. There are two approaches here, you can get the lowest role or the highest role for any capability. I set the function to be able to do both (plugins and themes can create capabilities that do not propagate up, I think), but by default, it will get the lowest possible user role for the capability parameter. 

The third allows you to find that ‘defining’ capability for a user role. By sending the role slug, it will walk through the list until it finds the first capability where the lowest level role is the parameter role. You can then use that capability to set the user level throughout your plugin/theme and then use it to build a set of setting checkboxes or a select where the roles are displayed, but the values are the defining capabilities. 

As far as I could tell, WordPress doesn’t have anything set up to do this yet. So here’s the code
