parsing string variables using CF 4.1.xx

Hi,

I am passing id's for records that I want in the url. I have the id's delimeted by a "|". I can parse these using javascript, but I need to use each one so that I can have my query select only records with those ids.

I am not familiar with cf string manipulating methods, and have not found a good solution yet.

Anyone know a good way to get these record ids ?

They are in this format: http://www.mysite.cfm?ids=1|2|4|7

Thanks for any input.

The easiest way is probably to treat it as a pipe-delimited list. Check the list functions in the docs.

Thanks for the input--I am glad there is a way.

I went to Macromedia, and searched google, but don't see a good tutorial for pipe-delimeted list methods in ColdFusion.

How do I get started using this method?

For example, to get the second element in your list you would do

#listGetAt( url.ids, 2, '|' )#

These functions are covered in detail in the docs.

How about if I wanted to do a foreach id in #listGetAt( url.ids)# type of application.

What method/procedure call be that would work for that?

<cfset idsNumber = ListValueCount(url.ids,"|")> isn't working for me either.

I just need to be able to count and identify the number of id's that I have in the URL that are separated by the "|" character.

OK -- I'm set.

I used the code you sent and some googling to figure out how to convert the url.ids to an array with ListToArray().

Now I can just index through the array using a for loop and #ArrayLen# of my array.

Thanks for input.
