wordpress - Wordpress - 将逗号添加到除最后一项之外的所有项目，删除下划线

Question

我正在使用 Wordpress 的高级自定义字段插件来显示复选框的结果。我有我想要的工作，我只想整理代码并添加以下内容：

1. 从社交媒体标签中删除下划线（某种剥离？？？）。
2. 如果可能的话，我想在每个“标签”之后显示一个逗号，但如果它是最后一个，则不会。

这是我的测试页面，它们是学科部分下的蓝色“标签”。

这是我的代码：

    <?php 
$catNames = array( 'branding','creative','development','exhibition','packaging','print','seo','social_media','usability','web','advertising','campaign','content','feasibility','publishing','research','strategy');

foreach($catNames as $name){
    if(in_array($name, get_field('categories') )){
echo '<a href="/tags/design/'.$name.'" title="'.$name.'">'.strtoupper($name).'</a>';       
    }
}
?>

Answer 1

嗯，这是非常基本的，你只需要做一个循环。我本可以用更多的信息写出更好的东西......无论如何，这应该完全符合您的代码所做的，但在一个循环中。

<?php 
$catNames = array( 'branding','creative','development','exhibition','packaging','print','seo','social_media','usability','web','advertising','campaign','content','feasibility','publishing','research','strategy');

foreach($catNames as $name){
    if(in_array($name, get_field('categories') )){ //I don't know what this is suppose to do
echo '<a href="/tags/design/'.$name.'" title="'.$name.'">'.strtoupper($name).'</a>';       
    }
}
?>

Answer 2

好的，这应该更好

<?php
$catNames = array( 'branding','creative','development','exhibition','packaging','print','seo','social_media','usability','web','advertising','campaign','content','feasibility','publishing','research','strategy');
    foreach($catNames as $name){
        $theID = get_cat_ID($name); // get the ID of each category
        echo '<a href="'.get_category_link($theID).'" title="'.$theID->name.'">'.$theID->name.'</a>';
    }
?>

Answer 3

试试这个：

<?php foreach( get_field('categories') as $category ): ?>    
    <a href="/tags/design/<?php echo $category ?>" title="<?php echo ucwords($category) ?>"><?php echo ucwords($category) ?></a>
<?php endforeach; ?>
