Re: [PHP-DB] comparison table script
You can get an idea here of what I would like to do http://www.bestbuy.com/ComputersPeripherals/DrivesStorage/CDRW.asp?m=488cat=511scat=514 So all information is displayed side by side, most of the time used to help decide between 2 or 3 products [bestbuy limits 10 selections in their comparison] The array is the part I need help with. I am not sure if what I had thought was the right track to pursue. Thanks much, olinux --- Miles Thompson [EMAIL PROTECTED] wrote: This isn't going to be the most helpful answer, because I'm wondering why you'd want to do this in the first place. All you really have to do is create a new array from the existing result set, transposing the columns. The number of elements in the array will be the number of car_ID's that are returned, the number of rows in the array will equal the number of attributes (columns) in the result set. Stepping through the result set and building the new array will be a rather interesting exercise in nested loops as you will be repeatedly going through the results set for each of ID, make, model, and color. After this array is built, then I'd worry about displaying it. Before that, however: Is it so important that the order of display be rearranged? Really, what's the difference? What if 8 cars are returned instead of 3? What if 20? Your table will blow out to the right, something users don't like. How do you plan to have users select the cars they want more information about? Only you can answer these, and maybe you have. In which case, good luck. Miles Thompson __ Do You Yahoo!?

Re: [PHP-DB] comparison table script
As you can only navigate record by record through the database table I think
the only way, as far as I know, is to store the record values into array
variables and print it to the page after you'd reached the last record.

Assunto: [PHP-DB] comparison table script
I would like to make a comparison script that will compare two items. Here
is an example and my "halfway" there solution. [at least i think so
Here is my table [for the sake of this example]
+-+
| car_ID |make | model | color |
+-+
| | | | |
| | | | |
| | | | |
| | | | |
||_|||
I would like the user to be able to select two or more cars to be compared
[these will be passed from an html form as car_ID
Table will be laid out something like this.
+-+
| |Car 1 | Car 2| Car 3 |
+-+
| car_ID |123 |234 | 345 |
+-+
| make|honda | honda | ford |
+-+
| model |civic | civic | tempo |
+-+
| color |black | blue | red |
+-+
basically the table is just displayed with fields and records transversed
[switched]
Now i select the info for the two cars, and $result holds the finished query
OK now to display it.
the first while loop will write the rows.
$table = "TR";
while ($row = mysql_fetch_array($result)) {
$carID = $row['carID'];
$make = $row['make'];
$model = $row['model'];
$color = $row['color'];
$table .= "TDCar ID/TDTD$car_ID[1]/TD";
2nd while loop - writes TD's which vary based on number of carID's
selected
It will loop until all cars have been included
somehow i need to change $carID[1] to $carID[2]
so I need some help on the best way to do this...
After i am able to do this I will loop thru until it does not exist, in the
case of the table above it would be $car_ID[4]
$next will represent previous number of the array +1
/* start of second while or if/for loop */
if ($car_ID[$next] != "")
$table .= "TD$car_ID[$next]/TD";
So basically that is as far as i have got. I would appreciate if anyone can
provide some direction
Thanks much,
olinux
