我需要一些关于OpenCart的PHP循环的帮助.
我需要做的是每4个循环包围一个div输出数据.
我有以下内容
<?PHP foreach ($categories as $category) { ?>
<div class="col-lg-3 col-md-3">.....</div>
<?PHP } ?>
我明白了
<div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div>
但我希望得到的是
<div class="row"> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> </div> <div class="row"> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> </div> <div class="row"> <div class="col-lg-3 col-md-3">.....</div> <div class="col-lg-3 col-md-3">.....</div> </div>
任何帮助将不胜感激 ：)
试试这个
<?PHP
$i=0;
$wrap_count = 4; // you can change this no of divs to wrap
foreach ($categories as $category)
{
$i+=1;
if($i%$wrap_count==1)
{
echo '<div class="row">';
}
?>
<div class="col-lg-3 col-md-3">.....</div>
<?PHP
if($i%$wrap_count==0)
{
echo '</div>';
}
}
if($i%$wrap_count!=0)
{
echo '</div>';
}
?>
