srand((float)microtime()*1000000);
$rand = "0.".rand();
$_SESSION['rand'] = $rand;
}
Which works but when you click on page 2, etc it gets randomized again.
How can I have it so when you refresh the page or revisit it randomizes the results but doesn't again when you click on page 2, page 3, etc?
I tried adding in the following in a few places but doesn't seem to do anything:
Code:
if(isset($_SESSION['rand']))
unset($_SESSION['rand']);
Also updated the $data_p query and now it looks like this:
Code:
$data_p = "SELECT * FROM model WHERE status = 'Active' ORDER BY RAND($rand) $max";

Not sure why that's not working.. Sessions can be a pain in the ass sometimes... Keep in mind that session stuff has to occur before anything else gets output since it uses cookies.... Cleaned things up a little and this "should" work.
Code:
$page = (isset($_REQUEST['page']) ? intval($_REQUEST['page']) : 1);
$page = ($page < 1 ? 1 : $page);
session_start();
$rand = (isset($_SESSION['rand']) ? intval($_SESSION['rand']) : 0);
if( $rand < 1 || $page < 2 ){
$rand = mt_rand(100000, 999999);
$_SESSION['rand'] = $rand;
}
session_write_close();
Without using sessions, you could just pass the rand parameter in the url along with the page number. At least that way you could then know for sure it's there or not.
