We have a schedule that is dynamically generated using, in part, this code:
<cfloop from="0" to="6" index="x">
<cfset thisDate = dateFormat(dateAdd("d",x,theDate),"yyyy-mm-dd")>
<cfoutput><tr><td colspan="4" class="date"><strong>#dateFormat(thisDate,"DDDD, M/D")#</strong></td></tr></cfoutput>
<cfif structKeyExists(dayData,thisDate)>
<cfif arrayLen(dayData[thisDate]) gt 0>
<cfloop from="1" to="#arrayLen(dayData[thisDate])#" index="y">
<cfoutput><tr>#dayData[thisDate][y]#</tr></cfoutput>
</cfloop>
<cfelse>
<cfoutput><tr><td colspan="4">There are no classes scheduled for this day</td></tr></cfoutput>
</cfif>
<cfelse>
<cfoutput><tr><td colspan="4">Schedule not available</td></tr></cfoutput>
</cfif>
</cfloop>
What I'm trying to do is dynamically insert an anchor (e.g., < a name="anchor">) depending on whether the date in the displayed row is the current date. So I want a cfif that will display the anchor on the row of the current day in the schedule. The goal is to link to this using the anchor.
Any suggestions are much appreciated.
So something like this?
<cfif dateFormat(now()),"yyyy-mm-dd") eq thisDate>
<a name="anchor" />
</cfif>
BTW, did you know you can loop over dates in ColdFusion.
<cfloop from="#theDate#" to="#dateAdd("d", 6, theDate)#" index="thisDate" step="#CreateTimeSpan( 1, 0, 0, 0 )#">
</cfloop>
This assumes that the dates are in a format that CF sees as dates, like what now() returns.

I'm working with quite a large array of items in a cfloop. I would like to pare this down and add pagination. Is there anyway in my cfloop to limit the array to the first 10?
I have
<cfloop array="#qryItems#" index="index">
I have tried turning it into a condition loop with no luck and a few other things. I haven't touched coldfusion in a while and am a little rusty. Google is not helping haha
I have tried
<cfloop from="1" to="10" array="#qryItems#" index="index">
and have also tried max_rows
<cfloop maxrows="10" array="#qryItems#" index="index">
each time I get the error message
"Attribute validation error for tag CFLOOP."
<cfloop from="1" to="10" index="index">
<!--- Then do your business with array elements qryItems[index], that is, with qryItems[1], qryItems[2],..., qryItems[10] --->
</cfloop>
There is no combination of attributes for cfloop to accomplish what your expecting. As BKBK suggested, you'll need to use a from/to loop to output a select group of records. If I understand your requirements correctly, I would update your cfloop with a new index variable as well, and then set the old variable by referencing the array element.
The two cfloops below output the same data, with the second displaying only the records in the pagination range.
<cfset qryItems = [1,2,3,4,5,6,7,8,9,10,'a','b','c','d'] />
<cfoutput>
<!--- Current loop: Outputs all records --->
<cfloop array="#qryItems#" index="index">
#index#
</cfloop>
<cfset paginationStart = 1 />
<cfset paginationEnd = 10 />
<!--- Only the range of of records requested --->
<cfloop from="#paginationStart#" to="#paginationEnd#" index="indexNumber">
<cfset index = qryItems[indexNumber] />
<!--- code remain the same --->
#index#
</cfloop>
</cfoutput>
I am passing dynamically named parameters in the url. (The number of sSearch parameters can go beyond 5 to 7 or 8 etc)
sSearch_0
sSearch_1
sSearch_2
sSearch_3
sSearch_4
sSearch_5
I want to run a loop to do a search within a query. I am trying like this:
<cfloop from="0" to="5" index="k">
<cfset counter = k>
<cfif IsDefined('url.sSearch_' & counter)>
<cfset "check_" & k = 'url.sSearch_' & counter>
</cfif>
</cfloop>
I am trying to write in a query like this:
<cfquery datasource="#coldfusionDatasource#" name="qFiltered">
SELECT *
FROM mytable
<cfif len(trim(url.sSearch))>
WHERE
<cfloop list="#listColumns#" index="thisColumn">
<cfif thisColumn neq listFirst(listColumns)> OR </cfif>
#thisColumn# LIKE <cfqueryparam cfsqltype="CF_SQL_VARCHAR"
value="%#trim(url.sSearch)#%" />
</cfloop>
</cfquery>
But it is not working. The error says check_ is undefined.
For dynamic variable naming using quotes, try:
<cfset "check_#k#" = 'url.sSearch_' & counter>

I am getting the following details in my form. I need to loop through the fields which have "attachment" in the name and add the count to the table, and also the values in the new table.
ATTACHMENT C:\ColdFusion10\cfusion\runtime\work\Catalina\localhost\tmp\neotmp3230094756217875313.tmp

ATTACHMENT3 C:\ColdFusion10\cfusion\runtime\work\Catalina\localhost\tmp\neotmp2809169853442728277.tmp
I am trying to do a loop over the form fields, but I am lost in between, and am unsure where to proceed.
<CFLOOP collection="#structform#" item="whichField">
<cfif FindNoCase('attachment',whichField)>
<cfset total = len(whichField)>
<cfoutput>#total#</cfoutput><br><br>
</cfif>
<CFOUTPUT>#whichField# = #structform[whichField]#</CFOUTPUT><br>
</CFLOOP>
I'm still not certain I've understood what's going on, so this might need tweaking/changing to make it work as needed, but this is without doubt a better approach:
<cfset Total = 0 />
<cfloop collection=#StructForm# item="FieldName" >
<cfif findNoCase('attachment',FieldName) AND len(StructForm[FieldName]) >
<cfset ++Total />
</cfif>
</cfloop>
<CFLOOP collection="#structform#" item="whichField">
<cfif FindNoCase('attachment',whichField)>
<cfset lstvalue = ListAppend(lstvalue,whichField)>
</cfif>
</CFLOOP>
<cfset total = ListLen(lstvalue)>
<cfif (len(total) AND total EQ 1) AND (Evaluate(lstvalue) EQ '')>
<cfset total = 0>
</cfif>
I am looping through the results of a query, and I need to limit the number of rows displayed. I need to use cfoutput because I'm using the group attribute, and I cannot use the maxrows because not all rows will be displayed.
I tried to use <cfbreak> inside the <cfoutput>, but that throws an error.
How can I break out of the <cfoutput> loop?
If your group by is only there to remove duplicates from your results I would suggest using your query to cut them down then you can cfloop (select distinct and reducing your returned column list).
If you are using your group by to "group" your results You could run a counter within your loop and a cfif statement inside your first loop to omit later results.
You could fake the group by option in your cfloop by matching value from previous row if you need cfbreak
<cfloop query="queryname">
<cfif queryname.column[currentrow-1] neq queryname.column[currentrow]>
#queryname.column#
</cfif>
</cfloop>
Random note: you can maxrows on any/all levels of your grouped cfoutput
<cfset tmp = querynew('id,dd')>
<cfloop from="1" to="20" index="i">
<cfset queryaddrow(tmp,1)>
<cfset querysetcell(tmp,'id',rand(),i)>
<cfset querysetcell(tmp,'dd',(i mod 4),i)>
</cfloop>
<cfquery dbtype="query" name="tmp">select * from tmp order by dd</cfquery>
<cfoutput query="tmp" group="dd" maxrows="2">#dd#<br
<ul>
<cfoutput maxrows="2" group="id"><li>#id#</li></cfoutput>
</ul>
</cfoutput>
You could use the cfthrow tag to trigger an exception that will allow you to break out of the loop using cfcatch you can then ignore the exception and continue processing. That will give you what you want.
<cftry>
<cfset i = 0>
<cfoutput query="qMyQuery" group="someGroup">
<cfset i = i + 1>
Parent
<cfoutput>
Child
</cfoutput>
<cfif i GTE 10>
<cfthrow type="break">
</cfif>
</cfoutput>
<cfcatch type="break">
<!--- DO NOTHING - THIS IS A HACK FOR NOT BEING ABLE TO USE CFBREAK inside cfoutput. --->
</cfcatch>
</cftry>
i created a table using coldfusion lists system, rows are months and the columns are cities, and the variable is the sales, now i need to add to every evaluated sale variable, the list of companies that made these sales, so far there is no problem with writting the sql of this table and the sales, but i cant define-#evaluate# the list of these companies that belongs to each sale in the table, since it is the LIST of companies, not one variable like sale, i hope i made myself clear :) here is my code:
The query with some sets:

it says: Variable company_COMPANY_ID_1_1 is undefined. where is my mistake?
i cant evaluate the LIST of company_idies in the same way i evaluated the NETTOTAL, since net total is not the list, but only one value... And thank you all for the help and attention! ;)
There are a lot of things you can improve in this code.
Incrementing the number of cities inside a loop is unnecessary. You can get the count directly from SQL (select count(*) from setup_city) or from CF after building your list (listlen(cities_list).
For that matter, it's unnecessary to loop through the list manually when you can simply use ValueList to have CF do the work for you:
cities_list = ValueList( get_city.city_id );
cities_list_name = ValueList( get_city.city_name );
There's no reason to build a list of months if all you're ever going to do is loop from 1 to 12. Use the 1-to-12 loop instead.
type_index doesn't need to be a list if you only have one item. Use the variable instead. Replace it with a list only when you actually need a list; this will also remove the need to use evaluate, which is making your code hard to read and difficult for people to follow. Same thing for cc_index.
Because scopes can be accessed as if they were structs, it's generally better (and can be significantly faster) to use structkeyexists( attributes, "money" ) rather than isdefined( "attributes.money" ). Specifying the scope for isdefined does help, of course ... isdefined( "money" ) is not only slow, but could return a completely different variable if you're not careful.
Speaking of structs, I would definitely recommend that you use them rather than concatenated variable names. It's extremely difficult to parse what you have written in order to understand what you are trying to do: using structs would make it easier to follow.
Finally, it looks to me like you're doing a ton of work in ColdFusion to do something that your database could do for you much more easily. If you need grand totals for companies by city, why not just do this?
<cfquery name="GET_SALES_GRAND_TOTAL" datasource="#dsn#">
SELECT
SUM(NETTOTAL) NETTOTAL,
SC.CITY_ID,
C.FULLNAME,
C.COMPANY_ID AS COMPANY_ID
FROM
#DSN2_ALIAS#.INVOICE I,
SETUP_CITY SC,
COMPANY C
WHERE
MONTH(INVOICE_DATE) >= 1
AND MONTH(INVOICE_DATE) < 12
AND C.COMPANY_ID=I.COMPANY_ID
AND SC.CITY_ID=C.CITY
AND PURCHASE_SALES=1
GROUP BY
SC.CITY_ID,
C.FULLNAME,
C.COMPANY_ID
</cfquery>
Is there a need to check that the month is between 1 and 12? If INVOICE_DATE exists, then it has to have a month between 1 and 12. I would either remove those lines from the query entirely or replace them with INVOICE_DATE IS NOT NULL.
You should then be able to get your table of results with something that looks roughly like this:
<cfoutput query="GET_SALES_TOTAL" group="AY">
<!--- months first --->
<tr>
<!--- month-specific stuff goes here --->
<td>month_header</td>
<cfoutput group="city_id">
<!--- city-specific stuff --->
<td><!--- format NETTOTAL however you want here ---></td>
</cfoutput>
</tr>
</cfoutput>
<tr>
<td>grand_total_header</td>
<cfoutput query="GET_SALES_GRAND_TOTAL" group="city_id">
<td><!--- format NETTOTAL here ---></td>
</cfoutput>
</tr>
Hopefully this is of some help to you. I would strongly encourage you to read up on arrays and structs; someone using evaluate is typically doing it the hard way when there is a much easier way of managing things, and there are plenty of examples both on SO and elsewhere of CF code that you should be able to learn from.
