aixen083 · February 16, 2015

So this is the scenario, i have 3 tables in my database voters.tbl, candidates.tbl, organisation.tbl

The user/Voters must see only the candidates that has the same id of a voter.

Let's say

ORGANISATION.TBL

---------------------- CANDIDATES.TBL

org_id: 1 -------------------

org_name: umbrella candidates_id: 1

firstname: ramon

lastname: mclights

org_id: 1

VOTERS.TBL

------------------

voters_id: 1

firsname: Anne

lastname: Sunga

org_id: 1

something like this

SELECT c.firstname
    , c.lastname
FROM candidates c
    INNER JOIN voters v USING (org_id)
WHERE v.voters_id = $loggedInID

the USING (org_id) does not work very well

Barand · February 17, 2015

Change it to

ON c.org_id = v.org_id

excuse me sir what is the importance of this script/code ?

$loggedInID

Barand · February 18, 2015

The id of the logged-in voter who wants to see the candidates in his/her organization. I have no idea how you are storing it and what your variable is but I thought that was a self-explanatory name for example purposes.

Sir this is my 1st query i made

$login_query=mysql_query("SELECT voters.voters_id, candidates.candidates_id, candidates.firstname, candidates.lastname, candidates.img FROM candidates INNER JOIN voters On voters.org_id = candidates.org_id WHERE id_number='$id_number' and password='$password' and status='Unvoted'")or die(mysql_error());

so i try to create new query in you suggestions.

$login_query=mysql_query("SELECT v.voters_id, c.firstname, c.lastname, c.image FROM candidates c INNER JOIN voters v ON v.org_id = c.org_id WHERE id_number='$id_number' and password='$password' and v.voters_id = $id_number and status='Unvoted'")or die(mysql_error());

Which of your tables contains "id_number" column. You didn't mention that before (I assume that "password" and "status" are in the voters table)

the id_number is the username of the voters.

Barand · February 19, 2015

WHERE id_number='$id_number' and password='$password' and v.voters_id = $id_number

Which of those two fields should match the value in $id_number?

(If the answer is both, why are you storing it twice?)

aixen083 · February 19, 2015

the id_number, password, status are in the same column of voters table.

my bad 1st i only store 1 id number for voters.. the problem is that how the voters determine if that candidates are same org_id as the voters.org_id because

That's what the JOIN on the org_id is for.

Then you would only use that column in the query

SELECT v.id_number
    , c.firstname
    , c.lastname
    , c.image 
FROM candidates c 
    INNER JOIN voters v ON v.org_id = c.org_id 
WHERE id_number='$id_number' AND password='$password' AND status='Unvoted'

WHERE id_number='$id_number' AND password='$password' AND status='Unvoted'

it works fine but it didn't get the exact i want to do.. any ways. do you have another option on how to perform this ?

Not without seeing your data and how it is really set up

I gave you the idea - you do a JOIN on org_id to get records with matching values in that column
