Select from 2 columns

[SkyRanger]

I am having a problem with selecting from 2 columns.

 

select from help where to_name = '$loggedin' and fr_name='$loggedin'

 

This is not right, I know what because it is not working.

 

Can anybody tell me what the proper code would be for this.

 

Thanks

Well you aren't selecting any columns.

 

Why don't you post your ACTUAL code. Including the mysql error and final query as demonstrated in my debugging your sql link.

 

Edit: Also, it appears you're trying to select a message that someone apparently sent to themselves.

$queryhd = "SELECT * from help where to_name='$loggedin' and fr_name='$loggedin' and opened IN ('y', 'n', 'r', 'c') order by 'time_sent' DESC";
$resulthd = $mysqli->query($queryhd) or die($mysqli->error.__LINE__);

 

No errors are reporting.

 

What I am trying to do is show messages sent and receied from a user.

A single message probably won't have the same user in the to and from column will it.

Think about it.

[SkyRanger]

No.

For example:

 

mid to_name from_name

1 user1 user2

2 user2 user3

3 user2 user1

 

 

I am trying to figure out how to show all message that user 2 has sent or received.

So the from_user _____ to_user will be that username. Fill in that blank.

(BTW: you really should be the PK, not usernames).

(BTW: you really should be the PK, not usernames).

 

? - sorry confused.

[Jessica]

You should use user_id not username to store relational data.

[SkyRanger]

ok, believe I got it to work, so far so good

 

select * from help where fr_name = '$loggedin' or to_name = '$loggedin'

 

Thank Jessica for the tip. Will be changing it over.
