我已经修改了用于网格视图的tpl以显示3列内容，我唯一的问题是下面的代码为视图创建了不必要的div。我有最多9个项目，应该在3行中输出，每列3个。修改下面代码的最佳方法是什么?以防止输出额外的div。
<?php foreach ($rows as $row_number => $columns): ?>
<div>
<?php foreach ($columns as $column_number => $item): ?>
<?php print $item; ?>
<?php endforeach; ?>
</div>
<?php endforeach; ?>
我会删除foreach语法的符号(但我认为这是非常个人的:-))
你可以使用模来检查你是否只有3列(如果我理解你的问题)。
<?php
// I´m assuming that $column_number is a zero based index
// if thats not the case you should add a counter to keep track of column numbers or if it is in sequence but isn't zero based you could easily update the calculates based in your starting index
foreach ($rows as $row_number => $columns) {
foreach ($columns as $column_number => $item) {
if ($column_number == 0 || $column_number%3 == 0) {
print '<div>';
}
print $item;
if ($column_number == 2 || $column_number%3 == 2) {
print '</div>';
}
}
// prevent open div tags
$total_columns = count($columns);
if ($total_columns > 0 && ($total_columns < 3 || $total_columns%3 != 0)) {
print('<div>');
}
}
我还去掉了所有php的开始和结束标签，以提高可读性。
