hey guys i have a 2 quick question for you pros.

 

i have a site that i made a database that contains products.now i have every thing set up to view the products like a catalogue.

 

now on the site it self i made a product page in there i want to post the image and link it to the information page.that it's ok.

 

now the part im scratching my head is i wan't to post like 4 images but i need them different like a gallery in a square,how can i fetch only like 5 images in random order.

 

2 question.

 

i wan't to make a cool background to put the product image and description but how can i make that same bgw repeat with another on the same page?cause usually u just put the fetch code once and it shows all the product in your database....

i tryed using the example in the sticky

 

$QQQ1 = mysql_query("SELECT
*
FROM
supps AS t1
INNER JOIN 
(
    SELECT
    ROUND(RAND() * (SELECT MAX(id) FROM supps)) AS id
) AS t2 
ON
t1.id >= t2.id 
ORDER BY
t1.id ASC 
LIMIT 1;  ");

I want to suggest something (which you DON'T have to adhere to), but I recommend selecting the SAME set of images each time, otherwise you risk alienating the user because you keep changing the images each time they come back to the page. Usability is very important in all web design aspects/decisions.

I'm hoping all you are wanting to provide is a random selection of products in a sidebar or something... not a random selection of pictures for the same product. Otherwise, I strongly suggest go with aschk advice. You will be sorry otherwise.Some decisions on our part, that we find are good marketing choices, have an impact on the user experience. And that sometimes (read, almost always) backfires.

 

Anyways,

 

SELECT * FROM table_name WHERE condition ORDER BY RAND() LIMIT how_many

 

Is how you draw a random sample of some table on your database

WHERE bin_data always returns true (unless NULL). So you don't need it. I included it in case you had a conditional expression. You probably want instead:

 

SELECT bin_data FROM supps ORDER BY RAND() LIMIT 4

 

Also, I noticed if(!$QQQ1) die(mysql_error()). Don't ever, ever do that ;)

You are giving powerful information to some user who may be of the insidious type and wondering just exactly how to get into your database. Instead something like:

 

if(!$QQQ1) die('error parsing your request. Please contact us if this problem persists.')

 

The same goes for the connection and open database up there... although I'm partial to the die() function and prefer instead to use my own functions.

 

EDIT: Sorry, got sidetracked by the die() thing and didn't finish my post. Anyways, you are getting the same image because you are reading from the resultset 4 times before moving on to the next record. What you should do instead is echo the whole TD just once. The while loop will take charge and echo it 4 times. Once for every record.
