我正在尝试在 PHP 中获得一些帮助,这样我就可以为循环中返回的每个单独的项目添加一个类或 ID。我正在使用一段代码(见下文)来返回分类法(位置)。我的所有 32 个位置都完美返回并显示在我的网站上。但是,我不能通过 css 单独设置每个位置的样式,因为没有与每个位置关联的唯一类。

返回的每个块在前端看起来像这样

<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>

对所有位置重复返回。正如您所看到的,没有办法实际单独设置每个样式,这正是我所需要的。

我返回位置的代码如下。我已经尝试过谷歌搜索和一些不同的方法来做到这一点,但我觉得我不合群,我想我会在这里向专家寻求帮助!

谢谢

更新 感谢一些帮助,我已经实现了这段代码,但仍然无法让它工作!

我将它添加到第 8 行的全局变量中 $i = 0; // initialise incrementing variable

然后我在 div 之前添加了这个,你可以看到我试图回显的额外类

// 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; ?>">

就在结束 div 标记之前(大约 100 行之后),我添加了结束代码

 $i++; // increment it
}

正如@sushanth reddy 所说,它应该真的很简单

$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
}
