no entiendo el porque. aqui les dejo mi codigo.
Código HTML :
<meta property="og:image" content="<?php echo 'http://' . $_SERVER['SERVER_NAME'] . DIR_WS_HTTP_CATALOG . DIR_WS_IMAGES . $product_array['products_image']; ?>" /> <meta property="og:title" content="<?php echo $product_array['products_name']; ?>" /> <meta property="og:description" content="<?php echo preg_replace('/[^a-zA-Z0-9\s]/','',preg_replace('/\s+/',' ',preg_replace("/<br>/", "",$product_array['products_description']))); ?>" />
Código PHP :
echo '<iframe src="http://www.facebook.com/plugins/like.php?href='.tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $product_info['products_id']).'&layout=standard&show_faces=false&width=350&action=like&font=arial&colorscheme=light&height=35" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:35px;" allowTransparency="true"></iframe>';
saludos.
