so need php method save image post id in ths line

file_put_contents('wp-content/uploads/2014/imagenamepostidhere.png', $image);

thanks

if $image fine, simple utilize concatenation or utilize double quotes utilize id:

file_put_contents('wp-content/uploads/2014/text-$id.png', $image); // you're using single quotes, variables not interpolated

either:

$id = get_the_id(); file_put_contents('wp-content/uploads/2014/text-'.$id.'.png', $image);

or

file_put_contents("wp-content/uploads/2014/text-$id.png", $image);

note: assuming have proper permissions.
