Form Solution -- Change Log

Version	Changes
5.10	Add note to top of email saying which web page sent the email. Remove blocking < and > characters in the body. Allow modifying email form name attributes via $Opt parameter. Add `suppressresults` to $Opt parameter, allowing suppression of the "results" output table on success.
5.9	Update docblock to indicate PHP 5 is required.
5.8	Requires PHP 5. The class has been updated to use PHP 5 OOP syntax. ereg is being deprecated in PHP 5.3, so use preg functions instead.
5.7	Several `EmailForm()` improvements: Renamed form elements to impede spammers. Removed `max` option. Was used in Name and Subject lines. Removed `maxlength` from `<textarea>` element. Removed `idf` from all but the `<form>` element. Removed `idp` from all but the preview `<table>` element. Added `prefixs` option, allowing you to prepend an identifier to the subject line of the emails sent to you by the form. Added `-f` as an additional parameter to PHP's `mail()` call. Added `action` element to the form. Added `Content-Type: text/plain` to email headers. Fixed minor typo in `EmailMatch` regular expression. Skip Time Sent output in Preview mode.
5.6	Coding standards tweaks.
5.5	Improve XHTML compliance by using selected="selected".
5.4	Use RFC 2822 to define legitimate email address characters. Improve docblocks a little bit.
5.3	Save some memory by assigning $Source by reference and unsetting HTTP_*_VARS earlier when possible. Added "Y" accesskey to `EmailForm()`. Added $ID parameter to `DateTimeOptionList()` for use with labels to permit accesskeys. Removed class from <br /> since classes don't apply to them.
5.2	Prepare for PHP5 defaults: $_GET and $_POST used first, then $HTTP_GET_VARS and $HTTP_POST_VARS used as fallback.
5.1	Changed line endings from CR LF to LF.
5.0	`AddressLineStandardization(), StateList()` and `CreditCardValidation()` moved to a separate classes. Started adding phpDocumentor comments. A few minor efficiency tweaks, requiring the use of PHP 4.
4.14	`empty()` check added to `CreditCardValidation()` to eliminate vulnerability. " changed to ' in some locations.
4.13	`CreditCardValidation()` added. Further modified `DateTimeOptionList()`: New options to the `Zero` argument, `E` and `B`, allow `E`mpty strings or `B`oth empty and zeros to be in the lists. `Default` and `Begin` are now validated. `Class` and `Size` now evaluated against `if (* != '')` instead of `if (*)`. Added the `C` option to the `Default` argument.
4.12	`DateTimeOptionList()` set up to handle empty strings for null times.
4.11	Eliminated situation where submissions containing variables named `$Keep` or `$Max` would interfere with proper cleaning of the input. System now clobbers the raw `$_POST, $_GET` and `$_REQUEST` superglobals. Accounted for changes in PHP so that the raw `$HTTP_POST_VARS, $HTTP_GET_VARS` and directly named variables are always deleted. Added the `EmailForm()` function. Added new `Keep` types: `AlphaNumAll, AlphaForeignNumAll` and `EmailForm`. Added a `Keep` pattern named `EmailMatch` for validating email addresses. Programmers can now add/edit the `Keep` patterns used in `StripBadCharacters()`. Further improved readability of the code. The system now has three reserved variable names: `Patterns_FS_RESERVED, Keep_FS_RESERVED` and `Max_FS_RESERVED`.
4.10	Made some code easier to read. `is_object()` check added to `CopyObjectContentsIntoForm()`.
4.09	`HTTP_GET` arrays are now handled. If input of `StripBadCharacters()` is an array, an empty string is returned.
4.08	Emails can now have "+" in them.
4.07	Changed the `DateTimeOptionList()` function in two ways. First, added the `$Class` argument. Second, changed an argument name from `$Selected` to `$Default` to maintain consistency between my programs. This second change has no impact on your scripts.
4.06	Added two optional arguments to the Constructor Function, providing the ability to dynamically alter which characters are kept in variables submitted by forms and URI query strings.
4.05	Tweaked `TimeValidateAndFormat()` so it doesn't get hung up if numeric strings are submitted rather than integers.
4.04	The `GetVariableHandler()` and `PostVariableHandler()` functions were eliminated and their functionality moved into the constructor function.
4.03	`DateValidateAndFormat()` ran into untrapped problems with dates earlier than 1970 when running PHP 4.0.2.
4.02	Added `Zero` argument to `DateValidateAndFormat()`.
4.01	First public release.
