I am only just learning PHP and I can grasp the concepts pretty well, but as I haven't done any programming since I was 10 (IF THEN GOTO...) I am struggling to fill in the gaps.
I have one table that lists all of my products and a url link to their photo.
I have another table that lists all of the products and 3 related products by their ID
1 Product 1 Url1
2 Product 2 Url 2
3 Product 3 Url3
1 Product 1 1 4 5
2 Product 2 4 2 8
I want to relate the two tables so I can pull out the 3 url links to each product.
In real world terms, I'm selling a skirt, when that is selected I want to display next to it 3 pictures of products related to the skirt that someone might like.
I was thinking along the lines of
Select ID Product URL
FROM Table1, Table2
Repeating 3 times for each related product.
That works fine, but how do I link it to the product that was originally selected? Normally it would be a WHERE statement for ID = 'colname' but I can't figure out how to add it in....
I'm sure this sounds confusing but if someone could point me in the right direction or to a tutorial/php site that discusses more advanced topics that would be great!!
Thanks a bunch!
I'm not sure why you'd have two tables both listing your products..unless I'm misinterpreting your post.
I think what you want is probably something like this:
ID ProductName Photo
1 Skirt image.gif
2 Tshirt image2.gif
3 Sweater image2.gif
ID ProductID RelatedProductID
1 1 2
1 1 3
So basically this is saying that product 2 is linked to product 1, and product 3 is linked to product 1.
Your queries might look something like this:
Query 1: SELECT * FROM ProductsTable WHERE ID = '1'
This will return all the info on your main product.
Query 2: SELECT ProductsTable.* FROM ProductRelationsTable LEFT JOIN ProductsTable ON productsTable.ID = ProductRelationsTable.RelatedProductID WHERE ProductRelationsTable.ProductID = '1'
This will return all the info on the linked products.
Okay that makes sense. My product is a variable though.
My first query is this
WHERE ID = 'colname'
Can I still use the join table to bring in related products to my variable product? I will give it a got waiting for your reply.
thanks for helping so quickly! :aparty:
Okay, that seemed to work great for bringing in the related product when I test it. But when I try to load my product page I am getting this error.
You have an error in your SQL syntax near 'WHERE You_may_like.ID = '14013'' at line 1
My Code is as follows
SELECT AtTheNet_data. *
FROM You_may_like LEFT JOIN AtTheNet_data ON AtTheNet_data.ID = You_may_like.Related1
WHERE You_may_like.ID = 'related'
where my variable 'related' is 7510 (one of my products) $_GET['ID']
I can pull up all of info in my recordset but as I said if I go to my product page now it doesn't work.
any more help??? Please.
