	A quick question. I have dynamic form fields like HEADLINEID_1 HEADLINEID_2 HEADLINEID_3 HEADLINEID_4 how can I count those in the action page. Also there are so many more fields are also getting submitted so, I can't use StructCount() I need something like I can specify that count that mactched headlineID_* Regards, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\| Purchase from House of Fusion, a Macromedia Authorized Affiliate and support the CF community. http://www.houseoffusion.com/banners/view.cfm?bannerid=37 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:174225 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=13123.11886.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54

	First off, on that page, make a hidden field, name it like num_heads, and give it the value of the number of headlineid forms. Then on the action page, which I am sure you will be using a loop, you can access each of those forms. You will use the evaluate function to access the form variables. <CFLOOP index = "num" from=1 to="#form.num_heads#"> <CFSET temp = evaluate("form.headlined_" & form.num_heads)> <--- Then do stuff with temp then the loop starts over again to the next form.---> </CFLOOP> I'm sure there's a betetr way tho ehehe. ----- Original Message ----- From: Asim Manzur To: CF-Talk Sent: Friday, August 13, 2004 12:39 PM Subject: Dynamic Form Element A quick question.

	You certainly do not need to do any of the below. Items in the Form scope are treated like a structure. To get all the fields, you can use structKeyList(). You can also use form.fieldnames, a built in list of form fields. To get the value, you use struct notation. Assume "key" is one form field. The value can be retrieved like so: form[key] So all you need to do is loop through and examine fields that begin with HEADLINEID.

	I assume you can set a hidden form field (intHeaderCount) for the number of HEADLINE_ID fields on the form page. <cfif Len(Trim(form['intHeaderCount'])) GT 0> <cfloop from="1" to="#form['intHeaderCount']#" index="x"> #form['HEADLINEID_' & x]# </cfloop> </cfif> HTH, Mike ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\| Sams Teach Yourself Regular Expressions in 10 Minutes by Ben Forta http://www.houseoffusion.com/banners/view.cfm?bannerid=40 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:174230 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=13123.11886.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54

Joe Rinehart 13 August 2004 21:42:53 [ permanent link ]
	Hey Ray, This is another approach I've used. Since there's a pattern to the names, I just reReplace out the fields we're trying to count from form.fieldNames and take the difference. <cfset count = listLen(form.FieldNames) - listLen(reReplaceNoCase(form.fieldNames, "headlined_[0-9]+,", "", "all"))> -joe ----- Original Message ----- From: Raymond Camden <rcamden-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> Date: Fri, 13 Aug 2004 13:07:09 -0500 Subject: Re: Dynamic Form Element To: CF-Talk <cf-talk-2K/2x8RPSj9p9z4BATjFtQC/G2K4zDHf@public.gmane.org> You certainly do not need to do any of the below.
