Set id of cf7 in the data save function [closed]

Question

My goal is to save the data sent by the cf7 module inside a table external to those created by wordpress I found this procedure:

1. Create Custom table

   CREATE TABLE candidate( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, title VARCHAR(50) );

2. Create contact form 7 fields

   [text* title] [submit "Send"]

3. Add Below code to function.php

     function contactform7_before_send_mail( $form_to_DB ) {
        //set your db details
        $mydb = new wpdb('root','','cistom_db','localhost');
   
        $form_to_DB = WPCF7_Submission::get_instance();
        if ( $form_to_DB ) 
            $formData = $form_to_DB->get_posted_data();
        $title = $formData['title'];
   
        $mydb->insert( 'candidate', array( 'title' =>$title ), array( '%s' ) );
    }
    remove_all_filters ('wpcf7_before_send_mail');
    add_action( 'wpcf7_before_send_mail', 'contactform7_before_send_mail' );
   

all clear and simple, however, I was wondering how to mix the specific id of the cf7 module?

$form_id = $contact_form->id();
if ($form_id == 2654 ) // 123 => Your Form ID.
{
}

Answer 1

Try this:

// Get current form.
$wpcf7      = WPCF7_ContactForm::get_current();
$contact_form_id = $wpcf7->id;
