I am getting a division by zero warning in my log file from this snippet of text in my Magento theme:

<li class="item<?php if(($i-0)%$_columnCount==0): ?>  last1<?php elseif($i%$_columnCount==0): ?> last1<?php endif; ?>">

Can someone tell me what is wrong? Thank you!

Here is the whole page of code:

<?php
$_item = $this->getItem();
$isVisibleProduct = $_item->getProduct()->isVisibleInSiteVisibility();
$canApplyMsrp = Mage::helper('catalog')->canApplyMsrp($_item->getProduct(), Mage_Catalog_Model_Product_Attribute_Source_Msrp_Type::TYPE_BEFORE_ORDER_CONFIRM
);
?>
<?php if ($_columnCount) { ?>
<li class="item<?php if(($i-0)%$_columnCount==0): ?> last1<?php 
elseif($i%$_columnCount==0): ?> last1<?php endif; ?>">
<?php } ?>
<div class="item-inner">

Try this.

    <?php if ($_columnCount) { ?>
    <li class="item<?php if(($i-0)%$_columnCount==0): ?>  last1<?php elseif($i%$_columnCount==0): ?> last1<?php endif; ?>">
    <?php } else { ?>
    <li class="item">
<?php } ?>

  • So it works, but for some reason I can't scroll the page with my mouse roller. My mouse scroll works when I disable it.

Your variable $_columnCount is zero at some point and modulo (the % operator) on 0 is illegal behaviour as you're essentially asking for the remainder of a zero divison.

  • Thanks for the response. Would I have to adjust any of the numbers to make this work and what would I change them too?
