Just as per my mySQL query, which obviously does not work, I'm aware of the SUM() function in MySQL, however, I don't want just the SUM() of all rows, I need to first get the maximum values from the table and then add them up. I know this would be hard to do in MySQL and would need a double query or something.
It's best to ignore MySQL for now, what I'm after rather is doing SUM using PHP.
So, like my orginal post, sum up, (add...Leave a comment:

Thanks for the reply. Unforutantely, I want the SUM of the MAXimum values, so essential something like this
SELECT SUM (MAX(car_value) )... which obviously wouldn't work.
Hence the reason why I thought first to do the MAX query using MySQL and then use a SUM function of some sort in PHP.
Can someone assist?Leave a comment:

mod_rewrite, replace spaces (%20) in URL param value with dash "-"
Hi,
I'm struggling to find an answer to my problem. In order to make my dynamic URLs search engine friendly, I need to replace spaces (%20) that appear in the URL with a dash "-".
For example,
change this dynamic URL:
www.example.com/directory.php?n ame=very%20nice %20house
to simply: www.example.com/very-nice-house
Really need some help with the complete mod_rewrite code.... -
Thanks for that. I tried your suggestion, yet it's not really working. What I need is to say have a number like 34000 to be displayed as 34,000, or 5000 as 5,000 or 300 to stay as 300.
I'm not sure if I had made it clear in my original post.
Many thanks....Leave a comment:

Are you able to provide assistance taking into consideration my code that I've included in my original post. I'm struggling to follow. I dont seem to have document.write anywhere (not sure what that does and how it would fit in the code)....Leave a comment:

Thanks for the reply. I don't see anywhere in my code where document.write is., but in anycase I've managed to derive from your suggestion and used '$'+ at the beginning of the variable - so thank you, that worked fine
[CODE=javascript]
document.getEle mentById('price ').value = '$+((sale_price ).toFixed(2));
[/CODE]
With regards to the thousands seperator, are you able to give me examples of how this can be done?

So I want to set this variable for any form field value that contains "_partofid" ! -
Fantastic! it worked perfectly. I just had to add the last bit which converts it back to date format and not a timestamp. Here is my final code. the url param is "date". Let me know if there is a shorter way of doing it??
[PHP]$timeEnd = strtotime($_REQ UEST['date']); //Changes the date int he URL to linux time stamp. URL param must be yyyy/mm/dd
$timeMon = $timeEnd - 518400; // 6 days * 24 hours/day * 60 minutes/hour...Leave a comment:
