I recently posted about changes that I needed to make to my Apache configuration files to get my custom virtual hosts settings working again, after upgrading to Mac OS X 10.8, aka Mountain Lion. In addition to those changes, I’ve also discovered that the update removed my JRun server settings from the httpd.conf file, making it impossible to start my local Adobe Coldfusion server.

These settings are added by the ColdFusion installer to setup JRun to correctly load the ColdFusion server instance. All you need to do is to put the settings back in the file and CF will start up again. However, I decided to put these settings into their own file so future Mac OS X updates will not remove them (although a future CF update would put new settings directly into the conf file again).

To get this done, follow these steps:

I recently needed to verify that a user’s input was a valid US social security number.  Initially, I thought it was just a simple task of verifying 3 digits, a dash, 2 numbers, another dash, and finally 4 numbers.  However, as I started reading online, I realized that each block of numbers has a significance (which I assumed) and more importantly to my task, that they have specific numeric ranges.

If you want to read the details of the format then see the links at the bottom of the post.  The gist is that as of June 25, 2011, a valid social security number needs to follow the following guidelines: View full article »

I recently updated a Mura CMS site I maintain, by adding a new “portal of portals” section. The main portal listed a series of guest authors that are writing articles for our site. Each author block in the portal list was actually its own portal or article pages. This is all common practice in Mura and in my opinion, one of the areas where it excels at adding content.

All the pages in this section are a two-column, 70/30 layout, with the main content on the left and some author specific information in the right. Both the author article portal list and each article all have the same content on the right, so I made an “authors info” component for that information. This content is a set of the author’s favorite Web sites. To make that content easy for my Editors to maintain, I extended the author’s portal template in the Class Extension Manager, and added new attributes to collect the link information. In my case, I added 10 fields to collect up to 5 links in the form of a Text/URL combination. My attributes are named Link1Text, Link1Url, Link2Text, Link2Url and so on.

So I now have one common “authors info” component in mu Mura admin that I include in the right side of my two column layout. The code view of that component looks like this:

<div class="span-7 last sidebar">
   <img alt="About the Author" src="/xyzsite/assets/Image/sidebars/sidebar_authorsinfo.gif" />

   <p style="font-style: italic;">"Take a look at some of my favorite sites"</p>
   <ul>
	[mura]dspInclude('display_objects/custom/ali/dsp_authorsInfo.cfm')[/mura]
   </ul>

<!--- static content to link users to other author sections --->
   <hr width="50px" />
   <p>See all of our authors pages:</p>
   <ul>
	<li> <a href="/index.cfm/articles/author/Author-A/">Author A</a> </li>
	<li> <a href="/index.cfm/articles/author/Author-B/">Author A</a> </li>
	<li> <a href="/index.cfm/articles/author/Author-C/">Author A</a> </li>
	<li> <a href="/index.cfm/articles/author/Author-D/">Author A</a> </li>
	<li> <a href="/index.cfm/articles/author/Author-E/">Author A</a> </li>
   </ul>
</div>

To pull the links and information into the component, I made a custom Mura display file (a CMF file) that I include in my template. That file started like this:

/xyzsite/includes/display_objects/custom/xyz/dsp_authorsInfo.cfm

<cfloop from="1" to="5" index="x">
   <cfset txt = $.content('Link'&x&'Text')/>
   <cfset lnk = $.content('Link'&x&'Url')/>

   <cfif (len(txt) GT 0) AND (len(lnk) GT 0)>
      <cfoutput>
           <li><a href="#lnk#">#txt#</a></li>
      </cfoutput>
   </cfif>
</cfloop>

In my Extended Attributes I have fields that collect a link and the text to hyperlink for up to 5 links. So here I run a loop from 1 to 5, set my link and text values, and then if both have content I add them as a list item.

When i saved all of this and reloaded an author’s portal page, I saw my links loaded as expected. However, when I opened an actual article written by that author, all I saw at the on the right was “Take a look at some of my favorite sites” then nothing. That is because my extended attributes are part of the main portal page and not the article sub-page. If you look at the code, I am loading Mura’s “content” object. The Mura Programer’s Guide explains that the “…Content scope wraps the CURRENT front end request’s contentBean”. So when I look at the portal page, where the custom link attributes are defined, they are available in the content scope.

So, if I can only get the currently loaded page’s info in the content bean, then how can I get the content from other pages? In my case, the Programmer’s Guide led me to a very simple solution: call the parent object using the getParent() method of the $.content() method. Doing this will return the data from the current’s page’s parent page as a contentBean. With that knowledge I updated my custom display file as so:

/xyzsite/includes/display_objects/custom/xyz/dsp_authorsInfo.cfm

<cfloop from="1" to="5" index="x">
<cfsilent>
   <cfset page = ListLast(cgi.PATH_INFO,'/') />

   <cfif  (page IS 'Author-A')
       OR (page IS 'Author-B')
       OR (page IS 'Author-C')
       OR (page IS 'Author-D')
       OR (page IS 'Author-E')
   >
     <!--- user is on a author portal page where the link values are available --->
     <cfset txt = $.content('Link'&x&'Text')/>
     <cfset lnk = $.content('Link'&x&'Url')/>
   <cfelse>
     <!--- user is on a article page, so grab info from the parent --->
     <cfset parentBn = $.content().getParent() />
     <cfset txt = parentBn.getValue('Link'&x&'Text')/>
     <cfset lnk = parentBn.getValue('Link'&x&'Url')/>
   </cfif>

   <cfif (len(lnk) GT 0) AND (lnk CONTAINS 'mysitedomain.com')>
       <cfset openIn = "_self" />
   <cfelse>
       <cfset openIn = "_blank" />
   </cfif>
</cfsilent>
   <cfif (len(txt) GT 0) AND (len(lnk) GT 0)>
       <cfoutput>
          <li><a href="#lnk#" target="#openIn#">#txt#</a></li>
       </cfoutput>
   </cfif>
</cfloop>

As you can see, at the top I updated my code to determine if the right side component was being loaded on an author’s page, by looking at a CGI var. If so, I set my links the same way I did originally. If not, then I assume the right side component is being loaded on a nested article page, so I first get my parent page’s contentBean, then set my links that way. In addition, I added some code to determine my link’s target value.

This all seems to work well. I would like to dig a little deeper and find out if I can dynamically find out how many attributes my page has. That way I wouldn’t need to hard code the 1 to 5 loop, and could easily add more link pairs in the future.

3.25 inch Floppy Disk

Yesterday, a co-worker brought me a 3.25″ floppy disk and asked if my Macbook could open it (you know because Mac’s never update their storage tech!). As it turns out, I could open the disk, as I still have an old VST USB Floppy Drive lying around in a drawer at home. When he told me that the disk stored some ColdFusion code from an old project they worked on in 1996. I became very motivated to help out, mainly just wanting to see some of their old code.

Well, today I brought in my disk and we cracked open the file.  There wasn’t any code, but there was some old libraries, MAPIPOP and SMTPGATE (both Windows .exe files to add functionality to their old project) and a ColdFusion White Paper as an HTML file. Turns out it’s from Allaire and is a white paper on ColdFusion version 1.5!  Yes I said 1.5.  I thought it was pretty neat to see what they supported then and some of the code examples.  The link to the file is below.  None of the links work of course and none of the images were on the disk, so it’s sort of bare bones.  At any rate, I got a kick out of reading it.  Hope you will too!
