InReview, by elegantthemes.com,  is an ideal starting platform for WordPress sites based on reviewing any kind of content, products and website. I think I can get some inspiration from the theme for my own Design Gallery. If you are interested in the WordPress theme used on cssexpression.com, please fill the contact form there.

Add Files To WordPress SVN Repository

add_action(‘wp_footer’, ‘omniture_tag’);

After searching the internet for a solution, I figured that the theme I was using needed to have the following missing statement in the footer.php just before the </body> tag to make it work:

<?php wp_footer(); ?>

ASP.NET CAPTCHA Library for reCAPTCHA

On September 16, 2009, Google announced acquisition of reCAPTCHA in a bid to digitize old time books and newspapers and support Google’s on going OCR research.

Custom URL rewrites in WordPress — A Getting Started Guide

Comment the following line in /wp-includes/default-filters.php:
add_filter($filter, ‘wpautop’)

Solution

<cfif cgi.CONTENT_LENGTH eq “”>
<cfset redirect_url = “http://” & CGI.SERVER_NAME & left(CGI.SCRIPT_NAME, len(CGI.SCRIPT_NAME) – 10)>
<cfheader statuscode=”301″ statustext=”Moved permanently”>
<cfheader name=”Location” value=”#redirect_url#”>
</cfif>

The above code works perfect for me although I don’t understand why Content_length is different for both URLs. I found the solution by cfdumping CGI variable using one url without index.cfm and another with index.cfm and observed that content-length was empty when url included index.cfm.

I hope it works for other ColdFusion folks as well.

Calling Google Custom Search (CSE) Web Services

<cfhttp result=”cseresult” url=”http://www.google.com/cse?cx=#googleAPIKey#&client=google-csbe&output=xml_no_dtd&q=#q#&start=#start#&filter=0″ method=”get” resolveurl=”yes” />

In the above statement, googleAPIKey=key of the custom search engine; q=search query; start=Zero based paging index, use start=10 for page 2; filter=0= Don’t filter similar result, use 1 to filter results.

Extracting Metadata and Results

<cfscript>
resultsxml = XMLParse(cseresult.FileContent);
RES = XMLSearch(resultsxml, “GSP/RES”);
if (ArrayLen(RES) gt 0)
{
totalResults = XMLSearch(RES[1], “M”);
searchResults = XMLSearch(RES[1], “R”);
iTotalResults = totalResults[1].XmlText;
iStartNumber = RES[1].XmlAttributes.SN;
iEndNumber = RES[1].XmlAttributes.EN;
}
</cfscript>

All XPath queries in above code return Arrays of Structures. RES element in the xml contains all the results information. SN is the index of the first result on the page while EN is the index of the last result on a page. For example, if page 2 has 4 results, then SN=11 and EN=14 while START remains 10.

Displaying Results and Pager

<div id=”google-cse”>
<cfif ArrayLen(RES) gt 0><!— If more than zero results returned —>
<!—Results Pager Header —>
<cfoutput><p>Results <b>#iStartNumber#</b> – <b>#iEndNumber#</b> of about <b>#iTotalResults#</b> for <b>#q#</b></p></cfoutput>
<cfloop index=”i” from=”1″ to=”#ArrayLen(searchResults)#”>
<cfset current_result = searchResults[i]>
<!—Unique Result —>
<div>
<h2><a <cfif isdefined(‘current_result.XmlAttributes.MIME’) AND current_result.XmlAttributes.MIME eq ‘application/pdf’>class=”mime_pdf”</cfif> href=”<cfoutput>#current_result.U.XmlText#</cfoutput>”><cfoutput>#current_result.T.XmlText#</cfoutput></a></h2>
<p><cfoutput>#current_result.S.XmlText#</cfoutput></p>
<p><cfoutput>#current_result.UE.XmlText#</cfoutput></p>
</div>
</cfloop>
<cfif iTotalResults gt numresults>
<cfset num_of_pages = Ceiling(iTotalResults/numresults) >
<cfset current_page = (iStartNumber – 1) / numresults + 1 >
<!—Pager Navigation —>
<div id=”cse-pager”>
<cfif current_page gt 1>
<cfset startnew = (current_page-2)* numresults>
<cfoutput><a href=”#CGI.SCRIPT_NAME#?q=#q#&start=#startnew#”>Previous</a></cfoutput>
</cfif>
<cfloop index=”i” from=”1″ to=”#num_of_pages#”>
<cfset startnew = (i-1)* numresults>
<cfoutput><a <cfif current_page eq i >class=”active” <cfelse>href=”#CGI.SCRIPT_NAME#?q=#q#&start=#startnew#”</cfif>>#i#</a></cfoutput>
</cfloop>
<cfif current_page lt num_of_pages>
<cfset startnew = (current_page)* numresults>
<cfoutput><a href=”#CGI.SCRIPT_NAME#?q=#q#&start=#startnew#”>Next</a></cfoutput>
</cfif>
</div>
</cfif>
</cfif>

The above code will show specific icon for PDF files and a basic pager that includes all the links according to the number of results found.

Above code integrates everything and handles manages output when provided with empty search query or getting zero results from Google. To see the implementation of the above code, Take a look at OSHACampus.com

GWT, however, does not eliminate the need to learn JavaScript or CSS and even provides ways to insert hand written JavaScript based on the complexity of the situation.
