I'm not sure why it needs to go into the session. Looking at your code this would mean you need to refresh the page before the actual error message is shown, because it is done in PHP when the page is originally generated.

Could you not return a success message directly in the request which deleted the item, and then show it immediately using javascript? You could use JSON to encode a success flag and a string message which is sent back. For example something like this:

//make post request to delete item
$.post'deleteThis.php', {oid:this.id}, function(data) {
    if (data.success) {
       $('.msg').html('Success: ' + data.msg);
    } else {
       $('.msg').html('Failed: ' + data.msg);
    }
}, "json");

deleteThis.php

$success = false;
$msg = '';
if(isset($_POST['oid'])) { 
    //delete $_POST['oid'] here        
    $success = true; //if successfull
    $msg = 'Deleted ok';
} else {
    $msg = 'No ID sent';
}

//send json data back
echo json_encode( array('msg'=>$msg, 'success' => $success) );
