How to install and configure your forms (pro version)

The following areas are covered in this guide:

More detailed information on how the code works can be found in the following areas.

Form installation overview

This guide covers how to install and configure your form (which was purchased after 9th September 2020).

Although our forms are simple to use and setup, they do contain a lot of flexibility and have been designed to work out of the box as much as possible with minimum effort. However, you are required to provide some settings during installation.

Using the form installer to set up your form

To make your setup as easy as possible, the form package comes with an installer. This is a form where you enter in the settings for your form. Here's an overview of the form installer.

Unzip the download package

The first thing to do when you download your package is to unzip the files to a folder on your computer. Double clicking on the zip file will usually extract the files for you.

Unzip files to computer

Upload files to your website

Connect to your website for file transfer (SFTP or Cpanel file upload for example), and upload ALL the files to the folder where you want your contact form to be installed. You must upload all files including the folder "fcf-assets" and all the files unside this folder.

Important: The installer will generate your form with the name fcf.form.htm, please make sure you don't already have a file with that name in the same directory as the installer (if you do, please back it up before running the installer!).

Upload files to your website

Browse to the installer

In your browser, go to your website as you normally would. If you uploaded your files to the root of your website, then go to Or if you uploaded your files to a folder (for example "folder"), then go to

Browse to the installer url

Enter your License Key

Install form license key field

Enter your License Key which you can find in your purchase email, or the members page.

Email message details

Form email message details

The first field "To address" is the email address where your form submissions will be sent to.

The second field "From" is the email address used to send the email from. It's highly recommended that you use an email address used by your hosting account, otherwise emails may be rejected.

The third field "Subject" is the email subject line used for the email.

There is more advanced settings you can use, more details available in the Configuration section later on.

Do you want to send an Auto-Response email to your visitor? Optional

Auto respond email to visitor

This is entirely optional, if you want to configure this, first tick the checkbox before completing the fields shown.

The first field "Subject" is the email subject line used for the auto-respond email to your visitor.

The second field "From" is the email address used to send the email from. It's highly recommended that you use an email address used by your hosting account, otherwise emails may be rejected.

Use SMTP to send emails

If you want to send your emails using SMTP (highly recommended!), tick this box and complete the fields with your own SMTP values.

Please check out the help guide for which form email smtp settings to use with your hosting provider.

Send form emails using SMTP

Protect your form with reCAPTCHA Optional

If you intend on using reCAPTCHA to protect your form from unwanted spambots and suspicious traffic, tick this box and enter your site key and secret key.

Use reCAPTCHA to protect your form

reCAPTCHA V3 is mostly invisible to the user. They no longer need to complete a challenge.

Complete the installation

The final stage is to click on the "Install Form" button. This will generate all the required code and configuration for your form. Once complete, you should see the following message.

form installation is complete

Your form is now ready to use!

Please now test your form to make sure it's been configured correctly and is sending emails. If you experience any problems, please double check all your settings. If you continue to have issues, take a look at the form troubleshooting page for help.

You can now add additional page contents around the form, or take the form HTML code and add it to your existing contact page.

Adding the form to your website

At this point, your form should be installed (see above). To add the form to an existing webpage, simply copy the HTML code from your new form page (fcf.form.htm) and paste it to your page.

To keep things nice and tidy, you should exclude the following code:

At the very top - remove

<!DOCTYPE html>
<html lang="en">
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

Keep the Style Sheets link (for example: <link href="fcf-assets/css/fcf.default.css" rel="stylesheet">).

Also remove.

<title>your title</title>


At the very bottom - remove


You can also move the JS and CSS code references to where you're other JS and CSS code references are. It's often best-practice to put the CSS references at the top of your page and the JS at the end.

The rest of this page contains more advanced information which you don't usually need to know.

Getting to know the files

Contact Form file types

Here's a quick list of some of the important files which make up the form package.

Usually, you only need to consider the configuration file. However, if you want more power, gaining a basic understanding of some of the other files will come in useful.

  1. fcf.form.htm - This is the form which appears on your website. You can rename it if you want.
  2. fcf-assets/fcf.config.php - Configuration file
  3. fcf-assets/css/fcf.default.css - Default styles sheet.
  4. fcf-assets/css/fcf.materialize.css - Alternative (material design) styles sheet
  5. fcf-assets/js/fcf.form.js - Form validation (client-side).
  6. fcf-assets/email-templates/ - Email templates (4 files in total)

The forms HTML file


The form code is made up of the four main sections:

  1. Reference to the style sheet
  2. The form
  3. The thank you message (hidden before the form is submitted)
  4. References to the JavaScript files
    <link href="fcf-assets/css/fcf.default.css" rel="stylesheet">
    <!-- 2: THE FORM -->
    <div id="fcf-form"> 
    <!-- 3: THANK YOU MESSAGE -->
    <div id="fcf-thank-you">
    <script src="fcf-assets/js/fcf.just-validate.js"></script>
    <script src="fcf-assets/js/fcf.form.js"></script>

Top Tip!

You may be interested in changing the message which is shown to your visitor after they submit the contact form.

This is the default code (your message may be different):

    <div id="fcf-thank-you">
    <!-- Thank you message goes below -->
    <h3 class="fcf-h3">Thank you for getting in touch</h3>
    <p>We appreciate you contacting us. We will get back in touch with you soon.</p>
    <!-- Thank you message goes above -->


Spam Prevention with reCAPTCHA

If you're using reCAPTCHA V3, then there are two additional parts you should be aware of.

  1. Sitekey inside a hidden form field
  2. Sitekey in a JavaScript reference
    <input type="hidden" id="recaptcha-sitekey" value="[SITEKEY]">
    <script src="[SITEKEY]" async defer></script>

You should make sure that you put your sitekey value in the [SITEKEY] parts.

The forms configuration file


As you can see from the file extension, this is a PHP file and is used by your Server when processing the form submissions.

The file is split into the following sections:

  1. License key
  2. Form field validation
  3. Form field mapping
  4. Email templates - incoming
  5. Email templates - auto-response
  6. Email message
  7. Email transport
  8. reCAPTCHA V3

Let's go through each part.

Configuration - License Key

    // ***********
    // ***********
    define('KEY', 'YOUR-KEY-HERE');

This one is nice and simple. Just replace the YOUR-KEY-HERE part with your license key.

Configuration - Form Field Validation

    // *********************
    // *********************
    $validate = array(
        "Name" => "NOT_EMPTY,2,60",
        "Email" => "EMAIL",
        "Subject" => "NOT_EMPTY,2,100",
        "Message" => "NOT_EMPTY,15,3000"

The purpose of the form field validation section is to set which fields on the form should be validated. This is pre-set, so you probably don't need to change.

It's also good to know that the form validation is already carried out in the browser prior to this. This is only a back-up in case your visitor has a browser issue that prevents the validation from functioning client-side.

The fifth line down has "Name" => "NOT_EMPTY,2,60". The first part is the field "Name", the second part is split into three "NOT_EMPTY", 2 and 60. This means that the field "Name" must not be empty, contain at least 2 characters and a maximum of 60 characters.

Configuration - Form Field Mapping

    // ******************
    // ******************
    $mapping = array(
        "Name" => "Your name",
        "Email" => "Your email address",
        "Subject" => "Help you with",
        "Message" => "Your message"

This Form Field mapping part allows you to map a friendly name against the field value. If the above validation fails, then a user is shown a message on the form. The user-friendly field name is used.

Example: 'Your email address' is required.

You usually don't need to change this as it's pre-set.

Configuration - Email Templates Incoming

    // **************************
    // **************************
    define('EMAIL_TEMPLATE_IN_HTML', '');
    define('EMAIL_TEMPLATE_IN_TEXT', '');

Email Templates Incoming is referencing template files that are used to create the email sent to you after someone uses your form. You do not need to change anything directly here, however, if you want to change the format of your email, then take a look at the template .htm and .txt files.

Emails are sent as multipart HTML with a Text alternative. So, if you can't receive HTML emails for whatever reason, then the text version will be shown.

Because we're looking at the configuration file, We'll not explain how the email template works here. You can find out more about that later.

Configuration - Email Templates Auto-Response Pro Feature

    // *******************************
    // *******************************
    define('EMAIL_TEMPLATE_OUT_HTML', '');
    define('EMAIL_TEMPLATE_OUT_TEXT', '');

    define('SEND_AUTO_RESPONSE', 'YES'); // YES OR NO
    define('EMAIL_OUT_SUBJECT', 'Thanks for your message');
    define('EMAIL_OUT_TO', 'FIELD:Email');
    define('EMAIL_OUT_TO_NAME', 'FIELD:Name');
    define('EMAIL_OUT_FROM', '');
    define('EMAIL_OUT_FROM_NAME', '');

If you would like to send an email to your visitor after they send a message through your form, then look at this section.

The first two lines reference where the HTML and Text email templates are located.

SEND_AUTO_RESPONSE - setting the value to YES will send the auto-response, NO will not.

EMAIL_OUT_TO - The default value for this is 'FIELD:Email', this means the email will be sent to the email address which was entered into the "Email" field in the form.

EMAIL_OUT_TO_NAME - The value for this is 'FIELD:Name', this means the email will be marked with the name which was entered into the "Name" field in the form.

The last two fields are very important (if you want to use an auto-response email feature), you MUST complete these two fields. The first with the email address which the auto-response email will be sent from, the next is the name related to it.

Examples of the last to fields:

define('EMAIL_OUT_FROM', '');
define('EMAIL_OUT_FROM_NAME', 'Example Inc.');

Configuration - Email Message

    // *************
    // *************
    define('EMAIL_TO', '');
    define('EMAIL_TO_NAME', '');

    define('EMAIL_TO_CC', '');
    define('EMAIL_TO_CC_NAME', '');

    define('EMAIL_TO_BCC', '');
    define('EMAIL_TO_BCC_NAME', '');

    define('EMAIL_FROM', '');
    define('EMAIL_FROM_NAME', '');

    define('EMAIL_REPLY_TO', 'FIELD:Email');
    define('EMAIL_REPLY_TO_NAME', 'FIELD:Name');

    define('EMAIL_SUBJECT_BEFORE', 'Contact Form:');
    define('EMAIL_SUBJECT', 'FIELD:Subject');
    define('EMAIL_SUBJECT_AFTER', '');

Here's a grid with details of each field:

Setting Description
Email address where the form will be sent to.
Name part of the email.
Email CC address where the form will be sent to.
Name CC part of the email.
Email BCC address where the form will be sent to.
Name BCC part of the email.
Email address where the form will be sent from. You can use "FIELD:Email" if you want the email address to be the one entered into the forms Email field. Some hosting providers or SMTP providers need to have a known email address in here, if that's the case, then you may need to put your own email address in here. It's ok for this to be your own email, as the EMAIL_REPLY_TO option below can also be used.
Name part of the email. You can use "FIELD:Name" if you want the name to be the one entered into the forms Name field.
Email address where the form will be sent if you reply to the message. You can use "FIELD:Email" if you want the email address to be the one entered into the forms Email field.
Name part of the email.
If you make use of the next setting using a "FIELD:Subject" option, then this value is prepended to the subject line.
If you want the subject to be a value from your form, for example if you have a "Subject" drop-down field, then you can use "FIELD:Subject". Or you can just enter a subject line. For example, "Contact form message"
If you make use of the above setting using a "FIELD:Subject" option, then this can be appended to the subject line.

Configuration - Email Transport

    // ***************
    // ***************
    define('USE_SMTP', 'YES'); // YES or NO
    define('SMTP_HOST', '');
    define('SMTP_USER', '');
    define('SMTP_PASS', '');
    define('SMTP_AUTH', 'YES');
    define('SMTP_SECURE', 'STARTTLS'); // STARTTLS, SMTPS (port 465) or empty
    define('SMTP_PORT', '587');
    define('SMTP_DEBUG', 'NO'); // YES or NO

Here are more details on these settings:

The first setting USE_SMTP can accept two values, either YES or NO. If you set it to YES, then you must provide values for the rest of the settings in this section.

If you're using SMTP, then you will need to supply the HOST, USER, and PASS values.

SMTP_AUTH should usually be set to YES. But if your SMTP server has authentication switched-off, then change this to NO.

The next two settings, SMTP_SECURE and SMTP_PORT usually work together. The most common settings are:

STARTTLS with port 587, or SMTPS with port 465.

Sometimes you may need to try different combinations to find the correct values for your environment.

If you're having issues getting your form to send emails, then set SMTP_DEBUG value to YES. This will provide a whole bunch of information that can help identify the issue. The most common issue is with the user, pass, and port number having the wrong values.

Configuration - reCAPTCHA Pro Feature

    // ************
    // reCAPTCHA V3
    // ************
    define('RECAPTCHA_SITEKEY', '');
    define('RECAPTCHA_SECRETKEY', '');
    define('RECAPTCHA_SCORE', '0.5');

If you would like to make use of Google's reCAPTCHA human verification system to stop unwanted automated spam, then complete this section.

Obtain your "site key" and "secret key" values from reCAPTCHA. Read our guide on how to get your Google reCAPTCHA Keys.

The RECAPTCHA_SCORE is a score which the service provides on how likely the form visitor is to be a bot. The score can be anything from 0 to 1. The current minimum accepted value is 0.5 if you want you can change this.

If you want to allow all messages through regardless of the score, then set RECAPTCHA_ACCEPT_LOW_SCORE value to YES. Otherwise set it to NO will silently discard any form submissions below the score limit.

The forms CSS file




The required styles for the form are included in this file. If you want to change anything to do with the colours or layout, this is the place to do it.

Depending on the form version you have, there may other alternative styles available which changes the form look. If you want to switch styles, change the CSS reference in your forms HTML file.

The contact forms JavaScript file


This file has a number of responsibilities, but the main one you may be interested in is the form field validation.

As mentioned above in the configuration section, the form validation is first done in the browser before the form is submitted.

This is the part in the JS file which sets the required validation settings you want.

rules: {
    Name: {
        required: true,
        minLength: 2,
        maxLength: 60
    Email: {
        required: true,
        email: true
    Subject: {
        required: true,
        minLength: 2,
        maxLength: 100
    Message: {
        required: true,
        minLength: 15,
        maxLength: 3000

In the above example, four fields have been included. Name, Email, Subject, and Message all specify that the fields are required and set the minimum and maximum acceptable value lengths. The email field is a required field, and it also states the validation type is 'email'. This will be pre-set for you, so you shouldn't need to change.

The forms Email templates


This file (along with the .txt version) is used to generate the email which is sent to you after each form submission.

Element like this one: {Name} will be replaced with the form field submitted value.


This file (along with the .txt version) is used to generate the email which is sent to your visitor (if you have enabled auto-respond option) after each form submission.
