Hi everyone, i need to learn coldfusion this weekend, ive started by converting my ASP code to Coldfusion..

<cfquery name="GetItems" datasource="#Request.MainDSN#">

<cfif #URL.brand# NEQ "" and #URL.all# NEQ "true">
Select * from parts where catid = #URL.catid# and brand = #URL.brand# order by brand
<cfelseif #URL.brand EQ# ""> 
Select * from parts where catid = #URL.catid# order by brand
</cfif>

</cfquery>
 i get this error Context validation error for tag cfif.. for people who know asp the original is below. Basically i want to choose which sql gets executed based on the URl..

if request.querystring("brand") <> "" and request.querystring("all") <> "true" then
set objRS = objDB.execute("Select * from parts where catid = " &request.querystring("catid")& " and brand = '" &request.querystring("brand")& "' order by brand")

else
set objRS = objDB.execute("Select * from parts where catid = " &request.querystring("catid")&" order by brand")
end if

Also if anyone has any coldfusion coding, something i can learn from, id really appreciate it if some could email me some code.. mrsigma@yahoo.com

Cheers

<cfif URL.brand NEQ "" and URL.all NEQ "true">
Select * from parts where catid = #URL.catid# and brand = #URL.brand# order by brand
<cfelseif URL.brand EQ ""> 
Select * from parts where catid = #URL.catid# order by brand
</cfif>


even better...

<cfquery name="GetItems" datasource="#Request.MainDSN#">
SELECT *
FROM parts
WHERE catid = <cfqueryparam value="#url.catid#" cfsqltype="cf_sql_varchar">
<cfif len(trim(url.brand)) and url.all neq 'true'>
AND brand = <cfqueryparam value="#url.brand#" cfsqltype="cf_sql_varchar">
</cfif>
ORDER BY brand
</cfquery>

just a small change to jyokumz code [it will work] , but i think catid is numeric so

also use comparenocase to compare strings
also always use cfqueryparam, its a better coding practice and also improves site performance, as it acts as bind variables

<cfquery name="GetItems" datasource="#Request.MainDSN#">
SELECT *
FROM parts
WHERE catid = <cfqueryparam cfsqltype="cf_sql_numeric" value="#url.catid#">
<cfif len(trim(url.brand)) and ComapreNoCase(trim(url.all),'true') NEQ 0>
AND brand = <cfqueryparam cfsqltype="cf_sql_varchar" value="#trim(url.brand)#">
</cfif>
ORDER BY brand
</cfquery>

change
ComapreNoCase(trim(url.all),'true') NEQ 0
to
CompareNoCase(trim(url.all),'true') NEQ 0

thanks
one last thing
do you know why this
<OPTION VALUE="index.cfm?all=true&catid=#URL.catid#&brand=">All</OPTION>

gives me this

http://localhost/CF/index.cfm?all=true&catid=#URL.catid&brand=

ive also tried
#URLEncodedFormat(Trim(URL.catid))#

thanks

first of all don't send brand if its not required and in ur query

write
<cfif isDefined('form.brand') And len(trim(form.brand))>
and brand = blah blaj
</cfif>

secondly..

is your option inside a cfoutpot tag or not

what i mean is

<OPTION VALUE="index.cfm?all=true&catid=<cfoutput>#URL.catid#</cfoutput>">All</OPTION>

Hart
