Fixate the random posts on the main page WordPress

John Cotton answers:

The way to do that is to fix the seeding for the randomiser. MySQL supports a constant param for its RAND function.

So adding this code will do the job based on creating a "fixed" value for any given session id. Same session id = same value.


function seed_rand( $orderby ) {
// Make sure we have a session id
if( !session_id() ) session_start();

// Generate a useful integer from the session id - a session id will
// always produce the same number
$seed = hexdec( substr( session_id(), 0, 5 ) );

// Use that 'constant' number as our seed
return "RAND($seed)";
}
add_filter('posts_orderby', 'seed_rand');


Clearly you don't want that running on each query, so you need to be careful about where you put the add_filter. If you are using a frontpage.php template file for instance, you could put the function in functions.php and then the add_filter in the template file.

Could you send me your file of function you are talking about ?

Tell me if I understand your problem :
the list of posts is generated randomly. This list must be the same all long the session.
That's right ?
