MySQL PHP query always returning 1 -

-

this script returns one, not actual number of online users. can fix code?

$oq = "select user user_archive time > (now() - interval 5 minute)"; $oresult = mysqli_query($con,$oq); $online_users = mysqli_num_rows($oresult);  if($online_users = 1) {      echo "{$online_users} user online";     }  if($online_users != 1) { echo "{$online_users} users online";     }

you need use == instead of =

if($online_users == 1) {      echo "{$online_users} user online";     }

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
