Minimum Word Count Custom Validation

  1. Hello,

    I had a need to perform custom validation on a field so that at least 150 words were filled in. I noticed on the support forums that no code example existed. Since I figured this out, I thought I would share my code. 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

    Kind regards,
    Casey

    // Added custom validation for minimum word count
    add_filter("gform_field_validation_11_70", "validate_word_count", 10, 4);
    
    function validate_word_count($result, $value, $form, $field){
        if (str_word_count($value) < 150) //Minimum number of words
        {
            $result["is_valid"] = false;
            $result["message"] = "Please enter at least 150 words.";
        }
        return $result;
    }
