Contact Form 7: Overwrite/Manipulate Posted Data Before Sending Email

Copy this code to your theme’s functions.php to manipulate the posted data by the visitor, update, add or remove fields and such.

There’s a lot that you can do with it!

add_filter( 'wpcf7_posted_data', 'compform_file_url', 10, 1 );
function compform_file_url($posted_data){
	
	// Add / update field with value
	$posted_data['new_field'] =  'new value';
	
	// Check if 'your-email' is [email protected]
	if ($posted_data['your-email']=='[email protected]')
	{
		//Remove the email field from the posted data
		unset($posted_data['your-email']);
	}
	
	return $posted_data;
}
