Question

I want to count the variables and show it somewhere in my code. I have a loop:

<cfloop query="get_serial">
  <cfif PROCESS_ID eq attributes.action_id> #SERIAL_NO# </cfif>
</cfloop>

and its query:

<cfquery name="get_serial" datasource="#dsn3#">
SELECT * 
FROM SERVICE_GUARANTY_NEW 
WHERE STOCK_ID = #attributes.action_row_id# 
ORDER BY SERIAL_NO
</cfquery>

Everything works fine, but I want to count how many variables are displayed exactly. I actually want to do it in this way because I lack of database variables. Actually it is possible to get the amount of these variables from database, I just don’t know which variables to use. That is why I want to count it manually.

Answer 1

If I understand you correctly you can do it with a counter in your loop.

<cfset counter = 0 />

<cfloop query="get_serial">
  <cfif PROCESS_ID eq attributes.action_id> 
    #SERIAL_NO# 
    <cfset counter ++ />
  </cfif>
</cfloop>

<cfoutput>Output #counter# times!</cfoutput>

EDIT: to answer your follow up question:

<cfset counter = 0 />
<cfsavecontent variables="myContent">

  <cfloop query="get_serial">
    <cfif PROCESS_ID eq attributes.action_id> 
      #SERIAL_NO# 
      <cfset counter ++ />
    </cfif>
  </cfloop>

</cfsavecontent>

<cfoutput>

  <p>Output #counter# times!</p>
  <p>#myContent#</p>

</cfoutput>

Hope that helps!
