Hi,
I am trying to put more structure into my CF code. My idea is to separate
the ColdFusion processing from the HTML structure and use CSS for the look
of the site. I am trying to get an idea of what is the best way to separate
the CF. I know that I could use custom tags, user defined function and if I
was using MX, then components. But these are for code that can across used
in multiple pages. What I am talking about is the CF for an individual
page.
What has all this to do with CFIF statements, well. I was thinking of
setting a series of flags that are checked against in my HTML. The CFIF
statements are there to check the value of these flags and amend the page
depending on these flags. So I want to be able to write good efficient CFIF
statements so that my code is up to speed.
Here's an example of what I am talking about:
<!--- Default ColdFusion Parameters --->
<cfparam name="QueryResults" default="" type="string">
<!--- ColdFusion Processing --->
<cfquery name="myQuery" datasource="myDSN">
SELECT *
FROM myTable
</cfquery>
<!--- Sets flags --->
<cfif myQuery.RecordCount EQ 0>
<cfset QueryResults = 1>
</cfif>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled</title>
</head>
<body>
<cfif QueryResults EQ "1">
<table cellspacing="2" cellpadding="2">
<tr>
<td class="mainFont">Results found.</td>
</tr>
</table>
<cfelse>
<table cellspacing="2" cellpadding="2">
<tr>
<td class="mainFont">No results found.</td>
</tr>
</table>
</cfif>
</body>
</html>
This is a simple example, but it shows how I want to keep the processing
separate at the top of the page.
My question, finally, is how are CFIF statements best written if I want to
code this way and or is there a better way of writing my CF code.
Thanks.
