php - Contact Form 7 - Get final mail HTML output

Solution:

The email body is in the classWPCF7_ContactForm which is passed to the hookwpcf7_before_send_mail

Use the methodprop to accessmail from there.

At this point, you can hook the mail and update the output however you want. Use $contact_form->set_properties(array('mail' => $mail)); to update the mail body to whatever you want. There is no need to return the function, as you're updating the object directly.

add_action( 'wpcf7_before_send_mail', 'dd_handle_form_submission' );
function dd_handle_form_submission( $contact_form ) {
    $mail = $contact_form->prop('mail')['body'];

    // Output the content to the error log of your website.
    ob_start();
    echo $mail;
    error_log(ob_get_clean());

    // Use this to push new content to the mail before sending
    $mail = $new_mail_content // whatever you set it to
    $contact_form->set_properties(array('mail' => $mail));

}

UPDATED Answer:

To get the content of the email after variable replacement, you have to use the filterwpcf7_mail_components

$components is an array of the mail components

['subject', 'sender', 'body', 'recipient', 'additional_headers', 'attachments']

Since this function has no output to the screen, you would have to send it to the error log to debug it.

add_filter('wpcf7_mail_components', 'filter_mail_components', 10, 3);
function filter_mail_components($components, $current_form, $mail_class){
    ob_start();
    print_r($components['body']);
    error_log(ob_get_clean());
    return $components;
}

Solution:

For security reasons contact form 7 doesn't allow html but using below hook you can get the form data & send email in html format.

// define the wpcf7_before_send_mail callback 
function action_wpcf7_before_send_mail( $contact_form ) {
 
    // Use wp_mail() to send an email. To send html in body first add_filter with content type text/html within this function

add_filter('wp_mail_content_type', function( $content_type ) {
            return 'text/html';
});
//Send email..... Even you can put php variable values within html
wp_mail( '[email protected]', 'your_subject', '<div>The message</div>' );

}; 
         
// add the action 
add_action( 'wpcf7_before_send_mail', 'action_wpcf7_before_send_mail', 10, 1 );
