使类别词单独出现在 ACF 上

Question

我正在使用 ACF 分类子字段。我正在寻找一种方法来显示该字段中的多个类别。我正在使用的代码显示所有类别，但单词相互接触，并且不分开。如何让那些分类词单独出现？

                        <?php
                        $term = get_sub_field('categories'); 
                            if( $term ) {
                              foreach($term as $t) {
                                $t = get_category($t);
                                echo $t->name;
                              }
                            }
                            ?>

您只需要 concatenate 一个 space 到您的类别名称。您可以通过多种方式实现这一目标。

最简单的方法是：

<?php
$term = get_sub_field('categories');
if ($term) {
    foreach ($term as $t) {
        $t = get_category($t);
        echo $t->name . ' ';
    }
}

This way concatenates a space ' ' after each element. So your string will end up with a final space (also called trailing whitespace). This may be an issue or maybe not.

另一种方式：

<?php
$term = get_sub_field('categories');
if ($term) {
    $first = true;
    foreach ($term as $t) {
        $t = get_category($t);
        echo ($first ? '' : ' ') . $t->name;
        $first = false;
    }
}

This time we use a boolean $first variable and the ternary operator Shorthand If/Else to concatenate the space before each element except the first one. This way your HTML code gets a clean string (without trailing spaces).

另一种获得干净字符串的方法是：

<?php
$term = get_sub_field('categories');
if ($term) {
    $cats = [];
    foreach ($term as $t) {
        $t = get_category($t);
        $cats[] = $t->name;
    }
    echo implode(' ', $cats);
}

In this example we push all category names to $cats array to finally convert (and echo) this array to string with implode.

希望对您有所帮助！ :)
