ok allora prima modifica il browse_1php
<div style="width:100%;padding: 0px 3px 3px 3px;">
<div style="float:left;width:20%;">
<script type="text/javascript">//<![CDATA[
document.write('<a href="javascript:void window.open(\'{image_url}product/{product_full_image}\', \'win2\', \'status=no,toolbar=no,scrollbars=yes,titlebar=no,menubar=no,resizable=yes,width={full_image_width},height={full_image_height},directories=no,location=no\');">');
document.write('<img src="{product_thumb_image}" {image_height} {image_width} border="0" title="{product_name}" alt="{product_name}" /></a>' );
//]]></script>
<noscript>
<a href="{image_url}product/{product_full_image}" target="_blank" title="{product_name}">
<img src="{product_thumb_image}" {image_height} {image_width} border="0" title="{product_name}" alt="{product_name}" />
</a>
</noscript>
</div>
<div>
<h3><a style="font-size: 16px; font-weight: bold;" title="{product_name}" href="{product_flypage}">
{product_name}</a>
</h3>
</div>
<div style="float:left;width:80%;">
{product_s_desc}
<a href="{product_flypage}" title="{product_details...}">{product_details...}...</a>
<br style="clear:both" />
<a style="font-size: 14px;"</a><FONT color=red>{product_price}
<br style="clear:both" />
{form_addtocart}
<br style="clear:both" />
{product_rating}
</div>
</div>
poi.....
modifica il shop-browse.php in questo modo
/*** Add-to-Cart Button ***/
if (USE_AS_CATALOGUE != '1' && $product_price != "" && !stristr( $product_price, $VM_LANG->_PHPSHOP_PRODUCT_CALL )) {
$form_addtocart = "<form action=\"". $mm_action_url ."index.php\" method=\"post\" name=\"addtocart\" id=\"addtocart".$i."\">\n
<p><label for=\"quantity_".$i."\">".$VM_LANG->_PHPSHOP_CART_QUANTITY.":</label> <input id=\"quantity_".$i."\" class=\"inputbox\" type=\"text\" size=\"3\" name=\"quantity\" value=\"1\" /> <input type=\"submit\" style=\"text-align:center;background-position:bottom left;width:160px;height:35px;cursor:pointer;border:none;font-weight:bold;font-family:inherit;background: url('". IMAGEURL ."ps_image/".PSHOP_ADD_TO_CART_STYLE ."') no-repeat left center transparent;vertical-align: middle;overflow:hidden;\" value=\"".$VM_LANG->_PHPSHOP_CART_ADD_TO ."\" title=\"".$VM_LANG->_PHPSHOP_CART_ADD_TO."\" /></p>
<input type=\"hidden\" name=\"category_id\" value=\"". @$_REQUEST['category_id'] ."\" />\n
<input type=\"hidden\" name=\"product_id\" value=\"". $db_browse->f("product_id") ."\" />\n
<input type=\"hidden\" name=\"page\" value=\"shop.cart\" />\n
<input type=\"hidden\" name=\"func\" value=\"cartadd\" />\n
<input type=\"hidden\" name=\"Itemid\" value=\"$Itemid\" />\n
<input type=\"hidden\" name=\"option\" value=\"com_virtuemart\" />\n
</form>\n";
}
