PVB Contact Form 7 Calculator vs Message Bridge for Contact Form 7 and VK

Message Bridge for Contact Form 7 and VK sends Contact Form 7 submissions to VKontakte users through a connected VK community. The number of VK recipients is not limited by the plugin: users subscribe to messages from the connected community, and the community acts as the notification bridge. To set up delivery: Create a VK community that will send the notifications. In the VK community settings, open Community management > Messages and enable community messages. Open Advanced > API usage, go to the LongPoll API tab, enable LongPoll API, and select API version 5.199 from the dropdown. Switch to Event types and enable Incoming messages. Open the Access keys tab and create a community access token with permission to use community messages. Open the Callback API tab and copy the group_id value. In the plugin interface, click Create Bot. Enter the Group ID, save the access token, or use the Copy PHP const controls to keep these values in PHP constants. Then wait for the bot status to become online. Configured and working bots are shown in blue. Ask each VK recipient to open the community messages and send start to the community. Approve or reject each subscription request in the plugin interface. Create a channel in the plugin interface to connect specific Contact Form 7 forms with the VK bot/community that should send their notifications. Hooks Filter cf7vk_skip_delivery Return a truthy value to stop delivery for the current Contact Form 7 submission before channels and messages are resolved.

Filter cf7vk_unfiltered_message Filters the Contact Form 7 mail body after mail-tag replacement and before VK-specific formatting. Arguments: $message (string), $submission (WPCF7_Submission). Filter cf7vk_prepared_message Filters the formatted VK notification text before it is passed to the linked delivery channels. Arguments: $prepared_message (string), $submission (WPCF7_Submission), $contact_form (WPCF7_ContactForm), $mail (array). Action cf7vk_channel_sendout Fires when a channel starts processing a prepared outgoing message, before bot and chat availability checks. Arguments: $channel (iTRON\cf7Vk\Channel), $message (string), $context (array). Action cf7vk_delivery_exception Fires when delivery relation lookup, chat status lookup, or VK transport delivery fails. The $chat argument can be null for relation lookup errors.

External Services VK API This plugin connects to the VK API to verify the configured community, request Bots Long Poll bootstrap data, load user and conversation details for connected dialogs, and send Contact Form 7 notifications to VK dialogs. When an administrator verifies or syncs a connection, the plugin sends the configured community ID, community access token, API version, and the identifiers required for the requested VK API call, such as peer IDs, conversation message IDs, and user IDs. When a Contact Form 7 submission is delivered, the plugin sends the destination dialog peer ID and the formatted notification text. That notification text can include the form title, mail subject, and submitted field values.

When an administrator runs dialog sync, the plugin sends the current Long Poll server key and timestamp issued by VK. VK returns new community message events and related dialog metadata, which can include peer IDs, sender IDs, conversation message IDs, message text, and chat titles.

Overview With PVB Contact Form 7 Calculator, you can easily turn any Contact Form 7 form into a calculator. Calculated fields are based on user input and selections in other parts of the form. The plugin can be used for creating various types of calculators, such as an ideal weight calculator, calorie calculator, quote calculator for hotel booking, car rental quote calculator, mortgage calculator, tax calculator, finance calculators, date calculator, etc. Features Advanced calculations – set your custom formula based on user input, for example: cost_per_day * days * (1 + (tax_percentage / 100)) Hide calculated fields – they can be visible to the user or not. Your choice! Server-side calculation – you don’t have to disclose your top secret formula! Calculations are performed behind the scenes, on the server. Calculate on button click – you can let your users trigger the calculations without submitting the form. Calculate on submit – values are always calculated on submit, so you can use them in your notification emails. Calculate on other events – you can also trigger calculations from another script at any time! Correct floating-point math – PVB Contact Form 7 Calculator handles decimal floating-point math properly, unlike many online calculators that introduce rounding errors when converting to binary and back, yielding incorrect results (such as 0.6 + 0.3 = 0.8999).
