You can use the code that DataAssist uses for alternating styles in tables.... just add code to the top of your page just about the <html> like:
<?php
//WA AltClass Iterator
class WA_AltClassIterator {
var $DisplayIndex;
var $DisplayArray;
function WA_AltClassIterator($theDisplayArray = array(1)) {
$this->ClassCounter = 0;
$this->ClassArray = $theDisplayArray;
}
function getClass($incrementClass) {
if (sizeof($this->ClassArray) == 0) return "";
if ($incrementClass) {
if ($this->ClassCounter >= sizeof($this->ClassArray)) $this->ClassCounter = 0;
$this->ClassCounter++;
}
if ($this->ClassCounter > 0)
return $this->ClassArray[$this->ClassCounter-1];
else
return $this->ClassArray[0];
}
}
?>
<?php
//WA Alternating Class
$WARRT_AltClass1 = new WA_AltClassIterator(explode("|", "prod-a|prod-b|prod-c"));
?>
then for the div tags add: class="<?php echo $WARRT_AltClass1->getClass(true); ?>"
