GF_GW_Req_Char_Length

Require a minimum and/or maximum character length for specific Gravity Forms fields, displaying an informative Gravity Form validation error to the user for disallowed entries.

Example Usage of this Class

See https://gist.github.com/cliffordp/551eb4f67b8db8e19d3d59a0f2b7a6f9 for several examples.

Example Composer Usage

Here's an example of what you might want to put in your own project's composer.php:

{
	"require": {
		"gf-gw-req-char-length/gf-gw-req-char-length": ">=2.0.1 <3.0"
	},
	"minimum-stability": "stable"
}

In plain English:

use version 2.0.1 or greater, as long as it is below version 3.0
only use versions that are official Releases in the project's repo

Pro tip: Installing this class via Composer allows you to do autoloading.

Of course, a big hat tip to Gravity Wiz:

This repo began as a forked from the May 30, 2014, version of https://gist.github.com/spivurno/8220561

Changelog

Version 2.0.1: October 26, 2018

Fix to avoid applying character length minimums to non-required fields that have no input.

Version 2.0.0: October 26, 2018

Pretty much fully rewritten.
Now requires Gravity Forms version 2.3+ (an arbitrarily-chosen recent version where GFForms::$version is used instead of the now-deprecated GFCommon::$version). Current GF version at time of this release is 2.3.6.
Now requires PHP 5.4+ (uses array short syntax).
Changed license from GPLv2+ to GPLv3+.
Renamed class to better describe actual functionality, as it can be used for minimum and/or maximum.
'field_id' argument now supports array type fields, such as Name and Address fields. (e.g. require Address Line 1 to be 5-30 characters long)
'field_id' argument now supports passing an array to apply the same rules and messaging to multiple fields at once. (e.g. same length and messaging to First Name and Last Name)
Added composer.php
Added multiple new examples to demonstrate available functionality, but removed them from this file in case this class is added to your project via Composer. See them at https://gist.github.com/cliffordp/551eb4f67b8db8e19d3d59a0f2b7a6f9
