每四个div环绕一个div [英] Wrap a div around every four divs

问题描述

我需要有关OpenCart的php循环的一点帮助.

I need a little help with a php loop for OpenCart.

我需要做的是每4个循环在数据输出周围包裹一个div.

I need to do is wrap a div around the output of the data every 4 loops.

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>

但是我希望得到的是

<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:)

Any help would be greatly appreciated :)

推荐答案

尝试一下

<?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>';
}
?>
