I've got a generic group that all of my users must be a part of. However, I have a chunk of users that aren't for some reason or another. So, I did a query to see who they are

Code
<br />SELECT * <br />FROM `w3t_Users` <br />WHERE U_Groups NOT <br />LIKE "%-3-%"


Now I need to do a query to manually enter -3- for each one that doesn't have that group. I would use "Update w3t_Users; set U_Groups="-3-"; but that would overwright the groups that are already there.

So what is the SQL statment that would ADD -3- without damaging what is already there?

I could help you if I follow.

In Threads the default group for Admins is 1 Mods 2 and User's 3

Why would you need to add -3- when they should already be -3-??


This should work for one user

UPDATE w3t_Users SET U_Groups="ALLGROUPS IN THIS FORMAT -1-2-3-" WHERE U_Username="USERNAME"

If you give me some more insight I may be able to help further.

I ran across this this weekend. I couldn't figure out how to do that with a query - as you have to add "3-" to the end of whatever groups are there.

I ended up writing a little script to do this.

Let me dig it up for you.

Can't the mass group change script be used in admin for this to join all those that don't belong to the group to it?

Well - to answer Omegatron - I run a very restricted board. You've got to register first (which puts you in group -6-) then upon approval, the admin has to manually put the user in the groups that they should have access to. Admins and Mods arent' a problem as they're already set up. Since the board is restricted, it doesn't automatically put people in -3-, and therein lies the problem. I had a little learning curve with the other admins and some folk got lost in the shuffle. There's less than 100 folks that are affected by this, but I simply do not have the time to go change that many records manually.

Josh - lemme know when you find that script. That would be most helpful.

Unfortunately, Ian, the mass group change can manipulate users that are already in a group, but cannot ADD users that aren't in it.

I thought it could - my mistake then. Sorry.

Ah OKay I understand now. You have a highly modified script

I kept banging my head against the wall trying to figure why user's where not in group 3 when thats the default in the Threads scripts.

If you do:

SELECT U_Username, U_Groups FROM 'w3t_Users'
WHERE U_Groups NOT LIKE "%-3-%"
ORDER BY U_Groups

If the U_Groups values you want to change are all the same, or there is only a few variations:

UPDATE 'w3t_Users'
SET U_Groups = "NEWGROUPVALUES"
WHERE U_Groups = "OLDGROUPVALUESTOREPLACE"

Something like this for example if most of the users are only "-6-":

UPDATE 'w3t_Users'
SET U_Groups = "-3-6-"
WHERE U_Groups = "-6-"

Or do I not follow what you want to do?

I think he wants to add group 3 to whatever groups they already have.

Untested..... backup your database first:

But this should work if you save it like a script and place it in your threads directory and run it in your browser:

Code
<br /><?<br /><br />require("main.inc.php");<br />$i = 0;<br />	$query = "<br />		SELECT U_Groups, U_Number, U_Username<br />		FROM {$config['tbprefix']}Users<br />		WHERE U_Groups NOT LIKE '%-3-%'<br />	";<br />  $sth = $dbh -> do_query($query);<br />  while(list($groups,$number,$username) = $dbh -> fetch_array($sth)) {<br />  	$newgroups = $groups."3-";<br />  	$newgroups_q = addslashes($newgroups);<br />	$query = "<br />		UPDATE {$config['tbprefix']}Users<br />		SET U_Groups = '$newgroups_q'<br />		WHERE U_Number = $number<br />	";<br /> 	 $stj = $dbh -> do_query($query);<br /> 	 echo "$username was $groups and was reset to $newgroups <br />";<br /> 	 $i++;<br />  }<br />  <br />  echo "Done - updated $i users.<br />";<br />  <br />  ?><br />

(Backup db first)

UPDATE w3t_Users
SET U_Groups = CONCAT(U_Groups,"3-")
WHERE U_Groups NOT LIKE '%-3-%'

And to see what this will replace before by doing:

SELECT count(*), U_Groups, CONCAT(U_Groups,"3-") FROM w3t_Users
WHERE U_Groups NOT LIKE '%-3-%'
GROUP BY U_Groups
