is it possible to generate a random number and then use cookies to pass this number to other page?
i cannot use session_start because it does not like my code for resizing the images that are uploaded and i cannot use get as the page the the random number is in a iframe and has no buttons on to append it to the url.
i have tried to post the data but had no joy the variable $rand has no value when checked on the next page. the code i used for the submit button looks like this
and the code i used to retrieve the value looks like this

Before the form you will need to generate the random number, also you have specified no value for the hidden field, change method= to value=.
To generate the random number do something like this:
To generate the random number do something like this:
<? // mt_rand(min value, max value) $rand = mt_rand(); ?>

<input type="hidden" value="<?=$rand ?>" name="rand" />
method only applies to the form tag. Last edited by ShawnCplus : May 9th, 2008 at 2:29 pm.
