How to change data before sending in Contact form 7?

2 Views

I have contact form on my website. And I need to change the value of one field before sending mail. For example name. I try like this: 

function contactform7_before_send_mail( $cf7 ) {
    $cf7->posted_data['your_name'] = 'John Doe';
}

add_action( 'wpcf7_before_send_mail', 'contactform7_before_send_mail' );

But in the email comes the value that is specified in the form.

  1. Recently faced the same problem.

    There is a field in this form called “[s2-name]” for example. When a visitor submit out a form, I want to get this field, then change and send. After some information searching, I wrote this code:

        add_action( 'wpcf7_before_send_mail', 'wpcf7_do_something_else_with_the_data', 90, 1 );
    
    function wpcf7_do_something_else_with_the_data( $WPCF7_ContactForm ){
    
        // Submission object, that generated when the user click the submit button.
        $submission = WPCF7_Submission :: get_instance();
    
        if ( $submission ){
            $posted_data = $submission->get_posted_data();      
            if ( empty( $posted_data ) ){ return; }
            
            // Got name data
            $name_data = $posted_data['s2-name'];
    
            // Do my code with this name
            $changed_name = 'something';
    
            // Got e-mail text
            $mail = $WPCF7_ContactForm->prop( 'mail' );
    
            // Replace "[s2-name]" field inside e-mail text
            $new_mail = str_replace( '[s2-name]', $changed_name, $mail );
    
            // Set
            $WPCF7_ContactForm->set_properties( array( 'mail' => $new_mail ) );
            
            return $WPCF7_ContactForm;
        }
    }

    Tested with: WP 5.4.2 and Contact Form 7 Version 5.2

  2. Try this:

    post.php

        $_POST["your_name"] = "John Doe");
    do_shortcode("[cfdb-save-form-post]");

    form.html

    <form class="form-contact" action="post.php" method="post">
  <input type="text" name="your_name" />
</form>
