Re: [OpenBD] creating an array of structs

[Alan Holden]

I'm glad that worked for you. Virtually every CFML engine I've used has given me random issues like this one : object elements persisting inside loops. I've come to explicitly cast the "index" element of (whatever complex thing I'm looping through) into its own variable right at the top of any loop, by habit now.

Ah but perhaps I need to be explicit about it being a new struct each time. Wait... let's try this. Ok. that is it. Now it works. I just added "<cfset fileInfo=strcutNew()>" just inside the loop and it works as expected. I wasearlier looking at a similar example I did a while back but couldn't see the difference (assuming implicit creation was the same as explicit) but in that case I used the full formal syntax for declaring and creating structs including declaring a new struct. So an easy fix. Thanks. On Monday, 6 January 2014 20:45:57 UTC-8, Al Holden wrote: oops. As a new struct, not a new array.

Just for debugging fun, add i as an array element too. On 1/6/2014 7:48 PM, Magnus wrote: I am trying to create an array of structs from values passed from a form. Using this code, the resulting array has the same value in each array cell from last iteration of the loop. The desired result, of course, is toi hae each pair of form values passed to a struct in each array cell. As far as I can tell, it seems the earsh array cell is only a reference to the fileInfo struct which gets rewritten each loop. I can't recall where I have read about assigning vallues and referencing variables in CFML to help me clarify wht is going on and how to get it working as I want. (If you are wondering, the form is from Plupload for uploading files. I want ot put the valuesinto an array because I will be doing a bunch of operations to or on the files and looping over and array each time will be simplier can repeatedly dealing with the dynamically generated form variables. Any help getting on track and beter understanding what is goingon here is much appeciated.
