PHP循环:每三个项目语法添加一个div [英] PHP loop: Add a div around every three items syntax

问题描述

我在wordpress中使用循环来输出帖子.我想将每三个帖子都包装在一个div中.我想使用一个计数器在循环的每次迭代中递增，但是我不确定如果$ i是3的倍数"或如果$ i是3-1的倍数"的语法. /p>

I'm using a loop in wordpress to output posts. I want to wrap every three posts inside of a div. I want to use a counter to increment on each iteration of the loop but I'm not sure of the syntax that says "if $i is a multiple of 3" or "if $i is a multiple of 3 - 1".

$i = 1;
if ( $wp_query->have_posts() ) : while ( $wp_query->have_posts() ) : $wp_query->the_post();
     // If is the first post, third post etc.
     if("$i is a multiple of 3-1") {echo '<div>';}

     // post stuff...

     // if is the 3rd post, 6th post etc
     if("$i is a multiple of 3") {echo '</div>';}

$i++; endwhile; endif;

我如何做到这一点?谢谢！

How do I make this happen? thanks!

推荐答案

为什么不执行以下操作?这将打开它，并在第三篇文章后将其关闭.如果没有要显示的3的倍数，请关闭结尾的div.

Why not do the following? This will open it and close it after the third post. Then close the ending div in the event there is not a multiple of 3 to display.

$i = 1;
//added before to ensure it gets opened
echo '<div>';
if ( $wp_query->have_posts() ) : while ( $wp_query->have_posts() ) : $wp_query->the_post();
     // post stuff...

     // if multiple of 3 close div and open a new div
     if($i % 3 == 0) {echo '</div><div>';}

$i++; endwhile; endif;
//make sure open div is closed
echo '</div>';

如果您不知道，%是模运算符，将两个数字相除后将返回余数.

In case you didn't know, % is the modus operator will return the remainder after the two numbers are divided.
