如何分配一个唯一的类在循环中返回的每个项目？ [英] How to Assign a unique class to each item returned in a loop?
本文介绍了如何分配一个唯一的类在循环中返回的每个项目？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图让PHP一些帮助，所以我可以一个类或ID添加到一个循环返回的每个单独的项目。我使用的是一块code（见下文）返回分类（位置）。我有我的所有的32个完美的回来，我的网站上显示。但是，我不能单独作为有与他们每个人的关联没有独特的类样式通过CSS的每个位置。
返回的每一块看起来像这样在前端
＆LT; DIV CLASS =块＆GT;
＆所述; A HREF =http://example.com/location/new-york＆GT;
＆LT; H2＆GT;
＆所述; A HREF =http://example.com/location/new-york＆GT;
安特里姆
＆LT; BR＆GT;
＆LT;跨度＆GT;（1农夫）LT; / SPAN＆GT;
＆所述; / A＆GT;
＆LT; / H＆GT;
这将重复所有地点的回报。正如你可以看到就没有办法单独其实每个样式而这正是我需要。
我的code返回的位置如下。我曾尝试使用Google和几个不同的方式来做到这一点，只是觉得我出我的联赛，我想我会问专家这里一些帮助！

更新
由于一些帮助，我已经实现了这个code，但仍无法得到它的工作！
我已将此添加到全局变量上线8 $ I = 0; //初始化变量递增
然后我加入这只是在div之前为u可以使用额外的类我想呼应见
//我说这条线作为我的div之前只是建议
＆LT; PHP的foreach（$ all_terms为$ all_term）{＆GT？;//我再添加一个新的类，但我不知道该怎么写
＆LT; DIV CLASS =块级=＆LT; PHP回声后$ I;？＆GT;＆GT;
刚刚闭幕div标签之前（大约100行后）我添加结束code
$ I ++; //增加它
}
解决方案
由于@sushanth雷迪说，这确实应该为
一样简单 $ I = 0; //初始化变量递增
的foreach（$ all_terms为$ all_term）{
//你的code的休息;如果你希望你的递增ID /类中使用$ I $ I ++; //增加它
}
I am trying to get some help in PHP so I can add a class or ID to each individual item returned in a loop. I am using a piece of code (see below) to return taxonomies (locations). I have all my 32 locations returned perfectly and displayed on my site. However, I cannot individually style each location via css as there is no unique class associated with each of them.
Each block that is returned looks like this on the frontend
<div class="block">
<a href="http://example.com/location/new-york">
<h2>
<a href="http://example.com/location/new-york">
Antrim
<br>
<span>(1 Farmer)</span>
</a>
</h2>
which repeats for all locations returns. As you can see there would be no way to actually style each individually which is what I require.
My code which returns the locations is as follows. I have tried googling and a few different ways to do it, but feel I am out of my league and thought I would ask the experts here for some help!
Thanks

Update Thanks to some of the help I have implemented this code, but still can't get it to work!
I added this to the global variables on line 8
$i = 0; // initialise incrementing variable
I then added this just before the div as u can see with the extra class I am trying to echo
// I added this line as suggested just before my div
<?php foreach ( $all_terms as $all_term) { ?>
// I then added a new class but I was not sure how to write this
<div class="block" class="<?php echo "post-" . $i; ?>">
Just before the closing div tag (about 100 lines later) I add the closing code
$i++; // increment it
}
解决方案
As @sushanth reddy said, it should really be as simple as
$i = 0; // initialise incrementing variable
foreach ( $all_terms as $all_term) {
// rest of your code; use $i when you want your incrementing ID / class
$i++; // increment it
}
