[SOLVED] Making a function for a product discount

[darkfreaks]

okay so im trying to make it if the category equals necklace and the product id returns with the word necklace the product price will be discounted on checkout.

 

 

<?php
if($cat=="necklaces"||$prodid= strpos("necklace",$prodid,TRUE)) 
{ $productprice=///$productprice discounted at 10 percent off 
;}?>

uh...

 

$productprice = $productprice * .9; // 10% discount

[marcus]

<?php
$string = "i love necklaces";
$string2 ="i love potatoes!";

if(preg_match("/necklace/i",$string)){
echo "String 1 has \"necklace\"";
}else {
echo "String 1 does not have \"necklace\"";
}

echo "<br><br>\n";

if(preg_match("/necklace/i",$string2)){
echo "String 2 has \"necklace\"";
}else {
echo "String 2 does not have \"necklace\"";
}

?>

 

Example.

 

$productprice = 100;
$discount = .1;
$productprice = $productprice - ($productprice*$discount);
echo $productprice;
