Question

Each page lists all the coupons available for a specific retailer. I query the database for all the coupon codes in the header since I count the number of rows returned and use that info in the meta title of the page. I now also want to display the titles of the first 2 coupons in the array. How would I go about extracting the first 2 results from the array without querying the database again?

This is what I have so far:

$retailer_coupons = "select C.couponid,C.fmtc_couponid,C.merchantid,C.exclusive,C.label,C.shoppingtip,C.restrictions,C.coupon,C.custom_order,C.link,C.image,C.expire,C.unknown,M.name,M.approved,M.homepageurl,M.category from tblCoupons C,tblMerchants M where C.merchantid=M.merchantid and C.begin <  ".mktime()." and C.expire > ".mktime()." and C.merchantid=".$merchantid." and M.display='1' and C.user_submitted='' order by C.custom_order desc, C.coupon desc";
$retailer_coupons_result = mysql_query($retailer_coupons) or die(mysql_error());
$count_coupons=mysql_num_rows($retailer_coupons_result);
$meta_title = ''.$name.' Coupon Codes ('.$count_coupons.' coupons available)';

Answer 1

Suppose I have 3 records in my table. If I execute below query, I will get 2 results however the count(*) will give me 3 as output

SELECT count(*) FROM temp.maxID limit 2

In your case it will be

$retailer_coupons =
    "select C.couponid,C.fmtc_couponid,C.merchantid,C.exclusive,C.label,C.shoppingtip,C.restrictions,C.coupon,C.custom_order,C.link,C.image,C.expire,C.unknown,M.name,M.approved,M.homepageurl,M.category
    from tblCoupons C,tblMerchants M
    where C.merchantid=M.merchantid
    and C.begin <  ".mktime()." and C.expire > ".mktime()."
    and C.merchantid=".$merchantid." and M.display='1'
    and C.user_submitted=''
    order by C.custom_order desc, C.coupon desc
    limit 2";

limit 2 will do the magic… Cheers!!!

Good Luck!!!
