Data from 2 tables, for multiple vehicles but limited by a another field

BCAV_WEB · November 10, 2010

Hey,

I'm wanting to have our site so cars and colours come from a backend database, so we have two tables one: cars, two: colours. My issue is that I have a two cars the Ford Ka and Ford Fiesta, but the KA colours are coming up on the fiesta and like wise.

Can anyone see the problem in my coding??

The first problem was that you didn't use CODE tags -- but I've fixed that for you.

The second problem is that I don't understand the problem.

BCAV_WEB · November 15, 2010

What are the coding tags, as I never seem to get them to wrok properly arent they [ ]??

Okay I have a website that has makes of cars such as ford, and they have models such as KA and Fiesta and then they have colours some which are unique to each car but some that are universal. So I have created two backend database one; car which holds all the car info, image, name, model etc.... and another called colours which has the car model, colour, colour type (metallic, solid etc...), colour image.

The way I thought this coding should work is by selecting the colour for each model of car where the model of table colours equals that of cars. Eg. if Fiesta (In colours) = Fiesta (In cars) then show the colour Green with Green.jpg etc...

But this isn't the case because the KA colours are also coming out on the Fiesta.

Does that make sense??

fenway · November 17, 2010

I don't see why you simply don't like the colours to the models.

BCAV_WEB · November 18, 2010

can you explain please

jdavidbakr · November 18, 2010

Put a field in your colors table that is a foreign key to the car table - then you can look up just the colors for the car by filtering the color table by the car's ID, and you can do joins between the two tables.

BCAV_WEB · November 19, 2010

but on php my admin, how do you add foreign keys??

jdavidbakr · November 19, 2010

if your tables are MyISAM there is no internal foreign key mechanism - but you can still use the concept, there's just not a way for the database to validate them. if your tables are InnoDB then, in the "Structure" view there is a link for "Relation View" which is where you set up the foreign keys.

BCAV_WEB · November 19, 2010

I'm using MyISAM, so how do I go about it?

If you go onto the link, you'll see what I'm trying to do.

If thats any help to you

jdavidbakr · November 19, 2010

Just add a column in your colors table that is car_id.

Or, if you need to have more than one color per car, have a table that is car_to_color with car_id and color_id as the two columns.

Then, to get the list of colors for car_id 1 you would either:

select * from colors where car_id = 1

or, if you use the second method,

select colors.* from colors join car_to_color on (color.id = car_to_color.color_id) where car_id = 1

I can't seem to figure it out :'(

Let's look just at your query logic and ignore the PHP formatting and strip away all the columns that aren't necessary for the logic.

Here's a basic situation: two cars, three colors, colors 1 and 2 go to car 1 and colors 2 and 3 go to car 2. Your tables, without all the extra info, would look something like this:

Car table:

car_id   car_name
1          Car 1
2          Car 2

Color table:

color_id    color_name
1              Red
2              Blue
3              Green

Car_to_color table:

car_id     color_id
1            1
1            2
2            2
2            3

So, basically, Car 1 can be either red or blue, and car 2 can be either blue or green. The primary key for the car_to_color table should be car_id and color_id together.

Now, you're looping through the cars:

select * from car

Each row you are using $car_row with mysql_fetch_array(), so to get the colors for the car whose row you're on:

select color.* from color join car_to_color on (car_to_color.color_id = color.color_id) where car_to_color.car_id = '{$car_row['car_id']}'

Be sure you understand the logic of how it should work before you try to put it into your code. You might try making a simple page that just lists the car id and its color id's just to simplify the code and give you a chance to make sure you know exactly how it's supposed to work.

BCAV_WEB · November 19, 2010

You're my hero! :D :D :D :D :D :D :D

First I forgot to put colour_id and car_id to have any data and secondly you've explained the logic and iv'e managed to get it to fit into my code and it works fine now!!
