Yeah, I wouldn't recommend passing an array via an HTML form, it just seems clunky. I'd definitely use $_SESSION variables. BUT.. If you absolutely had to pass this array via a HIDDEN form element, I'd recommend trying serialize() and unserialize() >From the PHP manual: "serialize() returns a string containing a byte-stream representation of value that can be stored anywhere. This is useful for storing or passing PHP values around without losing their type and structure. To make the serialized string into a PHP value again, use unserialize(). serialize() handles all types, except the resource-type. You can even serialize() arrays that contain references to itself. References inside the array/object you are serialize()ing will also be stored." I couldn't say it any better than that. http://us2.php.net/manual/en/function.serialize.php -TG > -----Original Message----- > From: Vail, Warren [mailto:Warren.Vail@xxxxxxxxxx] > Sent: Monday, November 22, 2004 7:13 PM > To: 'MikeA'; php-windows@xxxxxxxxxxxxx > Subject: RE: Re: Passing an Array in HTML > > > Only real array I've ever seen in HTML is one passed to > JavaScript.
