ColdFusion Preserve POST variable name case
Posted by Eric in ColdFusion, Programming on April 1st, 2008
ColdFusion provides access to POSTed data via the FORM structure. Unfortunately ColdFusion always upper-cases the names of these variables. Recently a chunk of code I was working on needed to know the original case of these keys. At first I worked on passing a hidden form field with the original field name text, but this bothered me as way too much of a work-around.
This chunk of code will give you a structure called FormContent where the case of the field names is preserved.
Unfortunately this code will not distinguish between two fields with the same name but different case. To do that, you’ll want to use a case-sensitive StructNew() alternative. I recommend CreateObject(”java”, “java.util.LinkedHashMap”).init(). This has the added value of preserving the order that the fields appeared in the calling form when you iterate over it for output. It has the disadvantage that you’ll have to properly match case of the keys when you retrieve them in your code.
ColdFusion REMatchAll

This ColdFusion method offers functionality similar to PHP’s preg_match_all function. It searches for the supplied regular expression in the supplied text. The return value is an array with one entry for each time the pattern matches the string. The array entries are structs with a numbered element for each parenthesized sub-expression within the match, and a zero-entry for the whole match.
It’s probably easier to see example data.
As you can see, it returns every match, position, and full text of the match, as well as each parenthesized subexpression. The example pattern basically matches {foo|bar|baz}, {foo|bar}, or {foo}, and returns the alphabetical sub-components as the sub-expressions.
Here is the code.
