Calculated Fields Form – AI Form Builder for WordPress – Contact, Payment, Quote, Quiz & More vs Forms

Calculated Fields Form is a full-featured WordPress form builder plugin. It lets you create any type of form — from simple contact forms to complex multi-step booking systems, quote generators, order forms, and payment forms — without writing a single line of code. Its standout capability is real-time dynamic calculations: form fields can automatically compute results (totals, prices, dates, distances, scores) based on values entered by the user. This makes it the ideal choice whenever a form needs to respond intelligently to user input. Is Calculated Fields Form only for forms with calculations? No. Despite its name, Calculated Fields Form is a complete, general-purpose WordPress form builder suitable for any use case. The “calculated fields” refer to an advanced feature the plugin offers on top of all standard form capabilities. You can use it to build: Contact forms — simple name, email, and message forms Booking and reservation forms — with date pickers and availability logic Quote and estimate forms — with automatic price calculation Order forms — with dynamic product pricing Payment forms — integrated with PayPal, Stripe, and many other gateways Registration and sign-up forms — for events, services, or user accounts Survey and quiz forms — with conditional logic and scoring Lead generation forms — connected to Mailchimp, HubSpot, Salesforce, and more Mortgage and loan calculators — with financial operation modules Shipping and logistics forms — with distance and travel time calculations Why choose Calculated Fields Form over other WordPress form plugins?

Send Contact Form 7, Gravity Forms, or Ninja Forms Submissions to a 3rd-party Service, like a CRM. Multiple configurable services, custom field mapping. Provides hooks and filters for pre/post processing of results. Allows you to send separate emails, or attach additional results to existing emails. Comes with a couple examples of hooks for common CRMs (listrak, mailchimp, salesforce). Check out the FAQ section for add-on plugins that extend this functionality, like sending XML/SOAP posts, setting headers, and dynamic fields. The plugin essentially makes a remote request (POST) to a service URL, passing along remapped form submission values. Based on idea by Alex Hager “How to Integrate Salesforce in Contact Form 7“. Original plugin, Contact Form 7: 3rdparty Integration developed with the assistance of AtlanticBT. Current plugin sponsored by Stephen P. Kane Consulting.

Hooks Please note that this documentation is in flux, and may not be accurate for latest rewrite 1.4.0 add_action('Forms3rdPartyIntegration_service_a#', $response, $param_ref); hook for each service, indicated by the # – this is given in the ‘Hooks’ section of each service provide a function which takes $response, &$results as arguments allows you to perform further processing on the service response, and directly alter the processing results, provided as array('success'=>false, 'errors'=>false, 'attach'=>'', 'message' => ''); success = true or false – change whether the service request is treated as “correct” or not errors = an array of error messages to return to the form attach = text to attach to the end of the email body message = the message notification shown (from CF7 ajax response) below the form note that the basic “success condition” may be augmented here by post processing add_action('Forms3rdPartyIntegration_service', $response, $param_ref, $sid); same as previous hook, but not tied to a specific service add_filter('Forms3rdPartyIntegration_service_filter_post_#, ... hook for each service, indicated by the # – this is given in the ‘Hooks’ section of each service allows you to programmatically alter the request parameters sent to the service should return updated $post array add_filter('Forms3rdPartyIntegration_service_filter_post', 'YOUR_HOOK', 10, 4); in addition to service-specific with suffix _a#; accepts params $post, $service, $form, $sid add_filter('Forms3rdPartyIntegration_service_filter_args', 'YOUR_HOOK', 10, 3); alter the args array sent to wp_remote_post allows you to add headers or override the existing settings (timeout, body) if you return an array containing the key response_bypass, it will skip the normal POST and instead use that value as the 3rdparty response; note that it must match the format of a regular wp_remote_post response. Note: if using response_bypass you should consider including the original arguments in the callback result for debugging purposes. add_action('Forms3rdPartyIntegration_remote_failure', 'mycf7_fail', 10, 5); hook to modify the Form (CF7 or GF) object if service failure of any kind occurs — use like: function mycf7_fail(&$cf7, $debug, $service, $post, $response) { $cf7->skip_mail = true; // stop email from being sent // hijack message to notify user ///TODO: how to modify the “mail_sent” variable so the message isn’t green? on_sent_ok hack? $cf7->messages[‘mail_sent_ok’] = ‘Could not complete mail request:** ‘ . $response[‘safe_message’]; } needs some way to alter the mail_sent return variable in CF7 to better indicate an error – no way currently to access it directly. add_action('Forms3rdPartyIntegration_service_settings', 'YOUR_HOOK', 10, 3) accepts params $eid, $P, $entity corresponding to the index of each service entity and this plugin’s namespace, and the $entity settings array allows you to add a section to each service admin settings name form fields with plugin namespace to automatically save: $P[$eid][YOUR_CUSTOM_FIELD] $rarr; Forms3rdPartyIntegration[0][YOUR_CUSTOM_FIELD] add_action('Forms3rdPartyIntegration_service_metabox', 'YOUR_HOOK', 10, 2) accepts params $P, $entity corresponding to the index of each service entity and this plugin’s namespace, and the $options settings array (representing the full plugin settings) allows you to append a metabox (or anything else) to the plugin admin settings page name form fields with plugin namespace to automatically save: $P[YOUR_CUSTOM_FIELD] $rarr; Forms3rdPartyIntegration[YOUR_CUSTOM_FIELD] add_filter('Forms3rdPartyIntegration_debug_message', 'YOUR_HOOK', 10, 5); bypass/alternate debug logging add_filter('Forms3rdPartyIntegration_plugin_hooks', 'YOUR_HOOK', 10, 1); Accepts an array of contact form plugin hooks to attach F3p to, and returns that array. Modify result to attach to additional plugin hooks, like GF edit. add_filter('Forms3rdPartyIntegration_service_filter_url', 'YOUR_HOOK', 10, 2); hook a function that takes the $service_url, $post_args and returns the endpoint $url used to modify the submission url based on mappings or other information $post_args contains the body and other wp_remote_post details Basic examples provided for service hooks directly on plugin Admin page (collapsed box “Examples of callback hooks”). Code samples for common CRMS included in the /3rd-parties plugin folder. Stephen P. Kane Consulting From the website and Handpicked Tomatoes: Transparent and Holistic Approach Transparency is good.
