Get SEO keywords automatically from an article or page

tjarko_NOSPAM-HONEYPOT_@carlosgallupa.com — Tue, 13 Oct 2009 15:19:00 GMT

I just finished a nice little function to get the "best" keywords for the page displayed in every website we build with our CMS. Below is an example, what you get is a list of the words that are mostly used in the given page and therefore the best to use as META keywords or tags in your page. At least if you like to be found on the contents of your page...

<cfsavecontent variable="txt">
A nice little piece of text with at least twice the word little in the text, and off course three times the word text ;-)
</cfsavecontent>

<cffunction name="getSEOWords" access="public" output="true">
    <cfargument name="content" required="true" type="string" />
    <cfset var lsStopWords = "stop wordlist in your language (google it)" />
    <cfset list = arrayToList(listToArray(REReplace(arguments.content, "[[:space:]]{2,}"," ", "all" ), " ")) />
    <cfset var stWords = structNew() />
    <cfset var lsTop = "" />
    <cfset var aSort = arrayNew(1) />

    
    <cfloop list="#list#" index="value">
       <cfif !listFindNoCase(lsStopWords, value) && !isNumeric(value)>
           <cfset value = trim(value) />
           <cfif structKeyExists(stWords, value)>
               <cfset stWords[value] = stWords[value] + 1 />
           <cfelse>
               <cfset stWords[value] = 1 />
           </cfif>
       </cfif>
    </cfloop>

    
    <cfset aSort = structSort(stWords, "numeric", "desc") />

    
    <cfloop from="1" to="15" index="i">
       <cfif stWords[aSort[i]] GT 1>
           <cfset lsTop = listAppend(lsTop, aSort[i]) />
       </cfif>
    </cfloop>

    <cfreturn lsTop />
</cffunction>

<cfoutput>
    #getSEOWords(txt)#
</cfoutput>

Delete errors since hotfix 3 Coldfusion 8

tjarko_NOSPAM-HONEYPOT_@carlosgallupa.com — Thu, 10 Sep 2009 10:13:33 GMT

Since the last hotfix these errors come flying by. This has always worked without any problems and all of a sudden these errors appear.

ColdFusion could not delete the file C:\somedir\somefile.jpg for an unknown reason.

Does someone know what a good solution is?? We need to delete the file after some file operations. These are not big files, maybe 1MB at the most. Seems like a timing or locking issue but it always worked until last week when we installed the hotfix.

Strange font behaviour with cfdocument pdf

tjarko_NOSPAM-HONEYPOT_@carlosgallupa.com — Fri, 17 Jul 2009 07:48:33 GMT

When we run a scheduled task that produces PDF files with cfdocument we get randomly PDF files with the complete text but in a strange font, or something?? (see example)

After searching on the internet I cannot find anything that explains this.... Does anyone have a clue on what's going on with these PDF files?? We produce hundreds a day without a problem but every now and then we get jibberish like below. It's becoming a real problem because these are contracts with people who are getting or wanting a home and can't see what's in the letter.

The PDF document that looks strange

If someone from Adobe sees this, I still have the other issue posted on this blog with PDF files (and more people do) fix it please!! We pay you for it!!

Thanks in advance if you can point me in the right direction.

Simple file upload protection

tjarko_NOSPAM-HONEYPOT_@carlosgallupa.com — Tue, 07 Jul 2009 10:27:32 GMT

These days it's all over the news that there is a new security bug in ColdFusion regarding file uploads and spoofing the mimetype. We use the bit of code below to simply check for the combination contenttype / extension. If the combination does not match... bye bye

 <cfset stAllow = structNew() />
<cfset stAllow["image"] = "jpg,gif,png,jpeg" />
<cfset stAllow["file"] = "doc,xls,pdf,rtf,txt" />
<cfset stAllow["application"] = "zip,rar,doc,pdf,xls,ppt,swf,flv,txt" />
<cfset stAllow["audio"] = "mp3,mpa,mpg,ra,wav" />
<cfset stAllow["video"] = "mov,qt,mpeg,mp3,mpa,mpg" />
<cfset stAllow["text"] = "txt,htm,html,log,css" />

<cfif structKeyExists(stAllow, file.contenttype) && listFindNoCase(stAllow[file.contenttype],file.serverfileext)>
    You may pass...
<cfelse>
    You will NOT pass!!!
    <!--- Delete the file or something --->
</cfif>

This works in a simple yet very effective way. People could still upload a file that is a .cfm and rename it to .gif but for the webserver it will be an image file.. no harm there. You can change the structure to your liking offcourse.

Some other tips are to only set "read" rights to the upload dir, place an application.cfm file with a <cfabort> tag in the upload dir (if it's accessible from the web)

Strange behaviour component, methods not found

tjarko_NOSPAM-HONEYPOT_@carlosgallupa.com — Wed, 27 May 2009 19:25:27 GMT

I have a really really strange bug. All my applications have a settings.cfc in the webroot of the application. Some cfc's have more methods than others but all my other cfc's extend the root settings.cfc, all cfc's are stored in an application variable called application.cfc and all applications have their own application_name (in case you are wondering)

The bug i'm having is that the correct settings.cfc is extended but a certain method in that cfc is not found..... if I remove all methods it keeps finding the other methods???, but if I change the this variables with other values in the settings.cfc it will see those changes???

It appears to me that the application scope is saving or caching a different settings.cfc and his methods instead of the correct one. Especially because if I remove the methods it will still show the methods in a cfdump....

Could anyone point me in the right direction??

Simple Standard CSS

michiel_NOSPAM-HONEYPOT_@carlosgallupa.com — Fri, 22 May 2009 12:16:56 GMT

Just add to your stylesheet and enjoy the simple enhancements..

::selection {background:#c3effd;color:#000;} /* Safari & Opera */
::-moz-selection {background:#c3effd;color:#000;} /* Firefox */

input, textarea, select {-moz-border-radius:4px;-webkit-border-radius:4px;}

Stop whining for scripting support

tjarko_NOSPAM-HONEYPOT_@carlosgallupa.com — Thu, 05 Feb 2009 09:04:26 GMT

In several articles people start asking for better scripting support in ColdFusion version 9. I hope from the bottom of my heart that this will not happen. ColdFusion has been and hopefully always will be a tag-based language and if you like scripting start using JSP or JAVA together with ColdFusion or not.

Scripting is killing for the language. It doesn't make sence to use scripting in a language that uses tags.. it's total chaos if you look at some of the applications where tags and scripting is used for the only reason that it is possible to do so... And don't say it's easier to set variables as arrays and structure because it isn't. For logical and "clean" coding we all need to be doing the same thing and that's using tags for this purpose, this way every other CF developer will understand what is being done, even the once that just startout using CF.

The language would be better of to be more strict about the use of it's tags and variables, then keep adding support for programming in different ways.

My humble 2 cents

Simple, but effective mobile redirect function

tjarko_NOSPAM-HONEYPOT_@carlosgallupa.com — Sun, 01 Feb 2009 21:21:52 GMT

 <cffunction name="isMobile" returntype="boolean">
    <cfset var ret = false />
    
    <cfif cgi.http_accept contains "text/vnd.wap.wml" || cgi.http_accept contains "application/vnd.wap.xhtml+xml" || structKeyExists(cgi,"HTTP_X_WAP_PROFILE")>
        <cfset ret = true />
    <cfelseif findNoCase("iphone", cgi.http_user_agent)>
        <cfset ret = true />
    </cfif>
    
    <cfreturn ret />
</cffunction>

<cfoutput>
    Is it a mobile? #yesNoFormat(isMobile())#
</cfoutput>

Lorem ipsum

Nothing new here, just never realised it actually stands for something..:

Cicero's original text:
…neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt ut labore et dolore magnam aliquam quaerat voluptatem."

H. Rackham's 1914 translation:
Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. (more in the Wiki)

Those guys just took some random words and letters from our homeboy Cicero! Also check out this brilliant site for us webdesigners: http://html-ipsum.com
