Maximum Word Count

    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;
    	}

  4. 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.
