Dynamic File Attachments

Hello,

I am trying to figure out how to dynamically attach files to mail2 based on checkboxes that are selected by the user when filling out the contact form.

Essentially if I have 2 checkboxes “File 1” and “File 2” if the user only checks “File 1” I want to email them and attach only File 1 to the email.

Been banging my head for hours trying to figure out hooks available in Conact Form 7 using filters like wpcf7_mail_components and wpcf7_before_send_mail

Example 1:

add_filter( 'wpcf7_mail_components', 'mycustom_wpcf7_mail_components');
function mycustom_wpcf7_mail_components($components){
define ('ATTACHMENT_PATH',$uploads['path'].'/attachments');
$pdf_filename = 'file1.pdf';
$components['attachments'] = array(ATTACHMENT_PATH.'/'.$pdf_filename);
return $components;
}

Example 2:

add_action( 'wpcf7_before_send_mail', 'create_unique_coupon_and_send_it' );
function create_unique_coupon_and_send_it( $cf7 ) {
	//check if this is the right form
	if ($cf7->id==741){
 		$uploads = wp_upload_dir();
		//define some constants
		define ('MY_FILE_PATH',$uploads['path'].'/myfile/');

		//set filenames
		$master_copy='https://www.mysite.it/subfolder/private/my_remote_file.pdf';
		$copy_to_send=MY-FILE_PATH.'attachment.pdf';

		if ($cf7->mail['use_html']==true)
			$nl="<br/>";
		else
			$nl="\n";
		// get the remote file
		$content = file_get_contents('$master_copy');
		if ($content !== false) {
			//make a copy of the master file and attach it
			if ( file_put_contents($copy_to_send, $content) !== false ){
				//Let'go to the file attachment!
				$cf7->uploaded_files = array ( 'coupon' => $copy_to_send );
			}
		}
		//Let'go to the file attachment!
		$cf7->uploaded_files = array ( 'coupon' => $copy_to_send );

		//append some text to the outgoing email
		$message=$nl.$nl.'Blah blah blah.....'.$nl;
 		$message.='So Long, and Thanks for All the Fish!'.$nl;
		$cf7->mail_2['body'].=$message;
	}
}

Any help or direction is appreciated.
