A maximum word count feature would be great.

I know there is maximum character count available, but word count as an option there would be very helpful.

This has been raised in pre-purchase question and this resource mentioned: http://roshanbh.com.np/2008/10/jquery-plugin-word-counter-textarea.html but having looked there I have no ideas about how to implement the code and don't have the resource to justify hiring a developer who does.

Add my vote for the integration of a word count feature :)

This can be done using the reverse of this post: http://www.gravityhelp.com/forums/topic/minimum-word-count-custom-validation

I added this to my functions.php file using the WordPress theme editor. Change the name of the filter to suit your situation.

Filter name: gform_field_validation_11_70
11 refers to my form id
70 refers to the field id on my form

Here is my modified solution:

// Added custom validation for minimum word count
	add_filter("gform_field_validation_1_6", "validate_word_count", 10, 4);

	function validate_word_count($result, $value, $form, $field){
	    if (str_word_count($value) > 50) // Maximum number of words
	    {
	        $result["is_valid"] = false;
	        $result["message"] = "Please enter 50 words or less.";
	    }
	    return $result;
	}

Another way to do it... we started with the resource in http://roshanbh.com.np/2008/10/jquery-plugin-word-counter-textarea.html but wound up a little differently.

Save this in /themes/yourtheme/js/ as jquery.gravity_wordcount.js:

jQuery(document).ready(function($) {
    $("[class*='count[']").each(function() {
        var elClass = $(this).attr('class');
        var maxWords = 0;
        var countControl = elClass.substring((elClass.indexOf('['))+1, elClass.lastIndexOf(']')).split(',');

        if (countControl.length > 1) {
            minWords = countControl[0];
            maxWords = countControl[1];
        } else {
            maxWords = countControl[0];
        }

        $(this).find('textarea').bind('keyup click blur focus change paste', function() {
            var numWords = jQuery.trim($(this).val()).replace(/\s+/g," ").split(' ').length;

            if ($(this).val() === '') {
                numWords = 0;
            }

            $(this).siblings('.word-count-wrapper').children('.word-count').text(numWords);

            if (numWords > maxWords && maxWords != 0) {
                $(this).siblings('.word-count-wrapper').addClass('error');

                var trimmedString = '';
                var wordArray = $(this).val().split(/[\s\.\?]+/);
                for (var i = 0; i < maxWords; i++) {
                    trimmedString += wordArray[i] + ' ';
                }

                $(this).val(trimmedString);
            }
            else if (numWords == maxWords && maxWords != 0) {
                $(this).siblings('.word-count-wrapper').addClass('error');
            }
            else {
                $(this).siblings('.word-count-wrapper').removeClass('error');
            }

        }).after('<span class="word-count-wrapper">Total Word Count: <span class="word-count">0</span></span>');
    });
});

In functions.php:

/* Gravity Forms Word Count Script */
function els_load_scripts() {
	wp_enqueue_script('gravity-forms-word-count', get_stylesheet_directory_uri() . '/js/jquery.gravity_word_count.js', array('jquery'), '0.1', true);
}
add_action('wp_enqueue_scripts', 'els_load_scripts');

Then in the form, for fields that need the word count, add the class ‘els-word-count[300].' Change [300] as needed for the maximum words that can be added to that particular field.
