Question

Here is the current code used to extract data from the database
$query = "SELECT username,time,UNIX_TIMESTAMP(time) as timestamp,UNIX_TIMESTAMP(active) as activestamp,IP FROM ".$table_name." WHERE success='1' ORDER BY active DESC";

Here is a sample set of data (with all unimportant fields removed)
ID | username
_01 | admin
_02 | admin
_03 | bob
_04 | jill

What I want is the total number of times each user appears, for example:
admin (2)
bob (1)
jill (1)

I need to add something along the lines of this COUNT(IF(name = 'admin', 1, NULL)) AS login_totals to the original query I showed you, but I can’t figure out the correct code. The name admin in my sample has to be the current username, so would I just put “username” there?

Answer 1

Try this: I added the count(*) and the group by

 $query = "SELECT username,time,
UNIX_TIMESTAMP(time) as timestamp,
UNIX_TIMESTAMP(active) as 
activestamp,IP, count(*) 
FROM ".$table_name." WHERE success='1' 
group by username 
ORDER BY active DESC";
