php - Echo two different user's column -


i want echo information account's line, shown on page.

exemple: if user aaron logins, , goes page "yasmine" want echo yasmine's picture.

this code now

php:

mysql_select_db("vestiged_sala");     $user = $_session['username']; $ppoza = '';  // add these lines in place of $result query $result = mysql_query("select * users username='$user' limit 1"); while($row = mysql_fetch_array($result)){             $ppoza = $row['ppoza'];     }  if (!$result) {     echo "could not run query ($sql) db: " . mysql_error();     exit; }

and html

<div class="ppoza"><?php echo $ppoza; ?></div>

the problem echo aaron's profile picture instead of yasmine's

you need run select current user's data.

select * users username= ?

or

select * users userid= ?

you should update driver pdo or mysqli can use parameterized queries i've shown here. prevent sql injections , quote data correctly.

you can read more here:

  2. http://php.net/manual/en/mysqli.quickstart.prepared-statements.php (or...)
  3. http://php.net/manual/en/pdo.prepared-statements.php (...dont use pdo , mysqli, (nor mysql_ separate)

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
