you can access the data attribute from the {list} tag within the {row} tags.
you have to search through $smarty->_tag_stack to find the enclosing {list}:
for ($i = count($smarty->_tag_stack) - 1; $i >= 0; $i--) {
$tag =& $smarty->_tag_stack[$i];
if ($tag[0] == 'list') {
$data = $tag[1]['data'];
break;
}
}
/* if $data is set here, then we found an enclosing {list} that has a
data attribute set */
then you have to loop yourself over the $data by setting $repeat at each call to {row}
/* we use the formerly unused $tag[2] to save the current row's count */
if (!isset($tag[2])) {
$tag[2] = 0;
} else {
$tag[2]++;
}
$i = $tag[2]; /* index of the current element */
if (isset($data[$i])) {
/* there are rows left, we assign one
this row will be used in the next iteration of the block function */
$smarty->assign('data', $data[$i]); /* if you want to acces {$data.SKU} */
$smarty->assign($data[$i]); /* if you want to acces {$SKU} */
$repeat = true;
} else {
/* we looped through $data and are done */
$repeat = false;
}
/* always return the block content's output unmodified
it contains the last iteration's output.
*/
return $content;
}
