form submit change field value

  • Hello.
    I’d like to do this:
    Before the form is submitted, change the value of one field (eg.your-name field).I think I found the code that does it, in submission.php file

    public function get_posted_data( $name = '' ) {
		if ( ! empty( $name ) ) {
			if ( isset( $this->posted_data[$name] ) ) {

				$posted_data['your-name']="lalala"; //i want to change this
				return $this->posted_data[$name];
			} else {
				return null;
			}
		}

		return $this->posted_data; //the values of all the fields
	}

    How can I add the new value to the posted data, can anyone help me with this? My goal is to show the new value in the success message after the form is submitted.

  • Since CF7 v3.9, you have to do this differently.

    See below for example:

    add_action('wpcf7_before_send_mail', 'custom_wpcf7_before_send_mail');
function custom_wpcf7_before_send_mail($form) {
  $id = $form->id; // gets current form id

  // CF7 form id => "form label (for you to distinguish)" -- you don't need this, but if you use multiple forms, it may be useful to TARGET x, y, or z forms instead of all forms
  $formTypes = array(
    176 => "Contact Page",
    //202 => "Questions/Comments Form"
  );

  // check if we want to run this code on selected form
  if(array_key_exists($id, $formTypes)) {
    // get current FORM instance
    $wpcf7 = WPCF7_ContactForm::get_current();

    // get current SUBMISSION instance
    $submission = WPCF7_Submission::get_instance();

    // get submission data
    $data = $submission->get_posted_data();

    // nothing's here... do nothing...
    if(empty($data)) return;

    // extract posted data
    $name     = isset($data['your-name'])     ? $data['your-name']     : "";
    $email    = isset($data['email'])         ? $data['email']         : "";
    $phone    = isset($data['phone'])         ? $data['phone']         : "";
    $message  = isset($data['message'])       ? $data['message']       : "";

    // do other stuff here

    // maybe do some replacements in the cf7 email body?
    $mail = $wpcf7->prop('mail');

    // Find/replace the "special" tag as defined in your CF7 email body
    $mail['body'] = str_replace("[MyCustomTag]", "Some dynamic text here", $mail['body']);

    // Save the email body
    $wpcf7->set_properties(array("mail" => $mail));

    // return current cf7 instance
    return $wpcf7;
  }
}

    Does this code go to the functions.php of my theme?
