Question

How to display variable values within stored html code.

Asked by: lexo

I have html and cf code stored in a database. When I call the HTML/CF code into a webpage, it displays all of the coldfusion variables as #variablename# on the actual generated page. I obviously need this to display the variable value.  How do I do this?

try use <cfhtmlhead

<cfhtmlhead text="??????????">

HuyBD;

 

by: lexoPosted on 2007-03-08 at 00:18:02ID: 18677181

That doesnt work either. I tried <cfhtmlhead text="#variableName#"> and all it did was remove my css div placement.  The variables still did not display properly, they display just like they are written in code.

coul you try

#Evaluate(DE(yourdata))#

HuyBD;

 

by: lexoPosted on 2007-03-08 at 01:10:02ID: 18677347

Nope I tried to put that in the main page as well as wrapping all variables in the database field with evaluate DE and no dice. Doesnt seem like this should be that hard to do but it's killing me.

database output is designed that way
otherwise you'd get a CF error everytime your db text had a # in it or
let's say the text is a forum like this where someone may post an example
"<cfif StructKeyExists>" which is malformed so another error would arise.

To do what you want to do you need to use "replacement flags"
lets say you have a newletter in your db that you mail out to subscribers.
You would construct the newsletter like so:
====================================
^tDate^<br />
^fName^,<br />
I'm sure you are as happy as a clam to receive this spam.<br />
Your full name is ^Name^.<br /><br />
Your Spam Team
====================================
that would be the text stored in the db

then when you email it you replace the flags like so:

<CFQUERY datasource="#Request.Datasource#" Name="getNews">
Select NewsText,NewsSubject,NewsFrom
From News
Where whatever ...
</CFQUERY>
<cfset TEXTMail=getNews.NewsText>

<CFQUERY datasource="#Request.Datasource#" Name="getSubscribers">
SELECT fname,lname, email
FROM Subscribers
where whatever ....
</cfquery>      
      
<CFMAIL FROM="#getNews.NewsFrom#"
      TO="#fname# #lname# <#email#>"            
      SUBJECT="#getNews.NewsSubject#"            
      SERVER="#Application.mailserver#"      
      type="html"
      query="getSubscribers">
      
<cfset TEXTMail=replacenocase(TEXTMail,"^FNAME^",getSubscribers.fname,"all")>
<cfset TEXTMail=replacenocase(TEXTMail,"^LNAME^",getSubscribers.lname,"all")>
<cfset TEXTMail=replacenocase(TEXTMail,"^NAME^","#getSubscribers.fname# getSubscribers.lname","all")>      
<cfset TEXTMail=replacenocase(TEXTMail,"^TDATE^","#DateFormat(now())# #TimeFormat(now())#","all")>
      <TABLE>
            <TR>
                  <TD colspan="100%" align="left">                  
                    #TEXTMail#                  
                  </TD>
            </TR>                        
      </TABLE>                  
</CFMAIL>

And it's as simple as that
you can get more creative also
good luck ...

try saving your html/cf code from the db to a temp file, then including that.
