Calculated Fields Form – AI Form Builder for WordPress – Contact, Payment, Quote, Quiz & More vs Brilliant Web-to-Lead for Salesforce

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?

Brilliant Web-to-Lead for Salesforce creates a solid integration between your WordPress install(s) and your Salesforce CRM account! People can enter a contact form on your site, and the lead (or case) goes straight into Salesforce CRM: no more copy pasting lead info, no more missing leads: each and every one of them is in Salesforce.com for you to follow up. Features You can fully configure all the different settings for the form, and then use a shortcode to insert the form into your posts or pages, or you can use the widget that comes with the plugin and insert the form into your sidebar! Previous contributors: Joost de Valk ModernTribe Daddy Donkey Labs Filters and Hooks Note: These should be placed in your active theme functions.php or a functionality plugin. Never edit a plugin directly (unless you understand the implications of doing so). You can use Pluginception to create a custom plugin for these to make them independent of your theme: https://wordpress.org/plugins/pluginception/ Filters salesforce_w2l_api_url Change the API url the plugin posts data to. Passes the form type (lead or case) add_filter( 'salesforce_w2l_api_url', 'my_w2l_api_url', 10, 2 ); function my_w2l_api_url( $url, $form_type ){ return 'https://my.custom-api-url.com/something/'; } sfwp2l_validate_field Provide your own validation logic for each field. An error array is passed in, along with the field name, submitted value, and field configuration (type, default value, required, etc). Here’s an example of blocking common free email providers: add_filter('sfwp2l_validate_field','block_non_biz_emails', 10, 4); function block_non_biz_emails( $error, $name, $val, $field ){ if( $name == 'email' ){ $non_biz_domains = array( 'gmail.com', 'yahoo.com', 'hotmail.com', 'aol.com' ); $domain = array_pop(explode('@', $val)); if( in_array( $domain, $non_biz_domains ) ){ $error['valid'] = false; $error['message'] = 'Please enter a business email addresss.'; } } return $error; } You can add to the $non_biz_domains to block other providers as well. salesforce_w2l_form_html HTML of the form before it’s returned to WordPress for display salesforce_w2l_cc_user_from_name Change from name (user confirmation) salesforce_w2l_cc_user_from_email Change from email (user confirmation) salesforce_w2l_cc_admin_from_name Change from name (admin notification) salesforce_w2l_cc_admin_from_email Change from email (admin notification) salesforce_w2l_cc_admin_email_list Adding this code to your functions.php file will add 3 emails to the list. You can add as many as you want and each will get an admin notification email. add_filter('salesforce_w2l_cc_admin_email_list','salesforce_add_emails'); function salesforce_add_emails( $emails ){ //uncomment line below to remove site admin //unset($emails[0]); $emails[]='[email protected]'; $emails[]='[email protected]'; $emails[]='[email protected]'; return $emails; } salesforce_w2l_cc_user_email_content salesforce_w2l_cc_admin_email_content Allows you to filter (append, prepend, modify) the email message content sent to the user or admin(s). add_filter('salesforce_w2l_cc_user_email_content','salesforce_filter_user_message', 10, 1); function salesforce_filter_user_message( $message ){ $message = 'Before the user message' . "\r\n\r\n" . $message . "\r\n\r\n" . 'After the user message'; return $message; } add_filter('salesforce_w2l_cc_admin_email_content','salesforce_filter_admin_message', 10, 1); function salesforce_filter_admin_message( $message ){ $message = 'Before the admin message' . "\r\n\r\n" . $message . "\r\n\r\n" . 'After the admin message'; return $message; } salesforce_w2l_cc_admin_replyto_email Filter the Reply-To email header (e.g. to allow replies to go to the form submitter) salesforce_w2l_returl salesforce_w2l_returl_{Form ID} Allows you to filter the value of a field before it is output to dynamically populate it with a value, auto set it based on another value, etc. Examples: // Filter Return/Success URL on a specific form // salesforce_w2l_returl_{Form ID} add_filter( 'salesforce_w2l_returl_1_tester', 'salesforce_w2l_returl_1_tester_example', 10, 1 ); function salesforce_w2l_returl_1_tester_example( $returl ){ return 'http://123.com'; } salesforce_w2l_success_message salesforce_w2l_success_message_{Form ID} Allows you to filter the contents of the success message before it is output to dynamically populate it with a value, auto set it based on another value, etc. Examples: // Filter Success Message on a specific form // salesforce_w2l_success_message_{Form ID} add_filter( 'salesforce_w2l_success_message_1_tester', 'salesforce_w2l_success_message_1_tester_example', 10, 1 ); function salesforce_w2l_success_message_1_tester_example( $success ){ return 'Testing 123'; } salesforce_w2l_field_value salesforce_w2l_field_value_{Form ID}_{Field Name} Allows you to filter the value of a field before it is output to dynamically populate it with a value, auto set it based on another value, etc. Note that the second filter requires you to replace {Form ID} and {Field Name} to be replaced with the relevant form id and field name. If you need access to the field or form settings in your filter you can use: $field = salesforce_get_field( $field_name, $form_id ); $form = salesforce_get_form( $form_id ); Examples: // Pre-check a checkbox add_filter( 'salesforce_w2l_field_value', 'salesforce_w2l_field_value_precheck_example', 10, 3 ); function salesforce_w2l_field_value_precheck_example( $val, $field, $form ){ $form_id = 1; // form id to act upon $field_name = 'checkboxfield__c'; // API Name of the field you want to auto check if( $form == $form_id && $field_name == $field && !
