Explanation

Want to make sure your form fields don't get overloaded with text? Here's how you can set limits on both characters and words for specific fields in WPForms.

Character Limit:

This code snippet sets a maximum number of characters a user can type into a specific form field.
It uses JavaScript to automatically apply a character limit when the page loads.
Simply replace the placeholder numbers with your actual form and field IDs.
Adjust the number '100' to whatever character limit you prefer.

Word Limit:

This part of the code restricts the number of words a user can enter in a form field.
It listens for input changes and trims the text if the word count exceeds the set limit.
Again, swap out the placeholder IDs with your actual form and field IDs.
Change the number '20' to set your desired word limit.

Both functions are hooked to the wp_footer action, ensuring the scripts are loaded at the right time. Just make sure to update the IDs to match your specific form setup, and you're good to go!

Code
// Function to add a character limit to a specific WPForms field
function wp_dudecom_limit_wpforms_field_character_count( $field_id, $form_data ) {
    ?>
    <script type="text/javascript">
        document.addEventListener('DOMContentLoaded', function() {
            var field = document.querySelector('#wpforms-<?php echo esc_js( $form_data['id'] ); ?>-field_<?php echo esc_js( $field_id ); ?>');
            if (field) {
                field.setAttribute('maxlength', '100'); // Set the maximum character limit here
            }
        });
    </script>
    <?php
}

// Hook the function to wp_footer to ensure the script is added to the footer
add_action( 'wp_footer', function() {
    // Replace '1' with the actual field ID and '123' with the actual form ID
    wp_dudecom_limit_wpforms_field_character_count( 1, array( 'id' => 123 ) );
});

// Function to add a word limit to a specific WPForms field
function wp_dudecom_limit_wpforms_field_word_count( $field_id, $form_data ) {
    ?>
    <script type="text/javascript">
        document.addEventListener('DOMContentLoaded', function() {
            var field = document.querySelector('#wpforms-<?php echo esc_js( $form_data['id'] ); ?>-field_<?php echo esc_js( $field_id ); ?>');
            if (field) {
                field.addEventListener('input', function() {
                    var words = field.value.split(/\s+/);
                    if (words.length > 20) { // Set the maximum word limit here
                        field.value = words.slice(0, 20).join(' ');
                    }
                });
            }
        });
    </script>
    <?php
}

// Hook the function to wp_footer to ensure the script is added to the footer
add_action( 'wp_footer', function() {
    // Replace '2' with the actual field ID and '123' with the actual form ID
    wp_dudecom_limit_wpforms_field_word_count( 2, array( 'id' => 123 ) );
});

Instructions

File Location: Add the following code to your theme's functions.php file or a custom plugin file.

Prerequisites:

Ensure you have the WPForms plugin installed and activated.
Identify the form and field IDs you want to apply the limits to.

Implementation Steps:

Open your WordPress admin dashboard.
Navigate to Appearance > Theme Editor if you are adding the code to functions.php, or go to Plugins > Editor if you are using a custom plugin.
Locate and open the functions.php file or your custom plugin file.
Copy and paste the provided code into the file.
Replace the placeholder numbers in the code:
- For character limit: Replace '1' with your specific field ID and '123' with your form ID.
- For word limit: Replace '2' with your specific field ID and '123' with your form ID.
Adjust the character limit (currently set to 100) and word limit (currently set to 20) as needed.
Click Update File to save your changes.
Test your form to ensure the character and word limits are working as expected.
