需要在最后列出的类别之前添加文本，然后在它的末尾.(Wordpress类别php) - Need to add text before the last listed category and then at the end of it. (Wordpress category php)

Need to add text before the last listed category and then at the end of it. (Wordpress category php)

我遇到了一个障碍，我希望在我的php代码中实现的设置。这段代码提取清单分组所在的类别，并在屏幕上显示为:

在家庭烹饪, 新鲜水果, 晚餐, 快餐

我希望实现的是:

在家庭烹饪、新鲜水果、晚餐和速食精选中有特色

如果你注意的话，在单词Quick Meals之前的和以及在它之后的Collections是我需要做的更改。我刚刚开始学习php，我不能在不破坏它的情况下进行这种调整。下面是我正在处理的:

如果你能把我从这个问题中拯救出来，我将非常感谢。我想没什么太难的。

$permalink = get_permalink( $id );

$seo = get_the_title()."- offers: ";

$Category_links = ' Featured in ';

$term_list_category = wp_get_post_terms(get_the_ID()， 'listings_categories'， array("fields" => "ids"));

$i = 0;

$count = count($term_list_category);

if ( $count > 0 ){
    foreach ( $term_list_category as $term_category ) {
        $thisCat = get_term_by( 'id', $term_category, 'listings_categories');
        $url = '<a class="listing-links" href="/listings/'.$thisCat->{'slug'}.'/'.'" title="'.$thisCat->{'name'}.' - Food listings " >'.$thisCat->{'name'}.'</a>';
        $i ++;
        $seo .= " " . $thisCat->{'name'} . "";
        $Category_links .= " " . $url . "";
        if ($count > 1 && $count !== $i) {$Category_links .= ", ";  $seo .= ", "; }
    }
}

本行下面--> $Category_links .= " "。$ url。

将代码改为…

        if($count-1 == $i){
            $Category_links .= " and ";  $seo .= ", ";
        }elseif($count > 1 && $count !== $i){
            $Category_links .= ", ";  $seo .= ", "; 
        }
    }
    $Category_links .= " Collections";      
}

基本上你是在检查你是否在数组($count-1)的最后一个元素的旁边，并插入一个" and "而不是"，

然后在循环外添加$Category_links .= " Collections";添加到输出的末尾

我更喜欢字符串输出的简单数组操作;

基本

//example of assigning those categories
$cats = array('Cat 1', 'Cat 2', 'Cat 3', 'Cat 4');
$ccats = count($cats);
foreach($cats as $i => $cat)
{
    //apply slug as needed here     
    $cats[$i] = '<a href="">' . $cat . '</a>';  
    if($i < ($ccats-1))
    {
        $cats[$i] .= ',';
    }
}
array_splice($cats, ($ccats-1), 0, array('and'));
$cats[] = ' Collections';
echo implode($cats, ' ');

实现(未测试)

$cats = wp_get_post_terms(get_the_ID(), 'listings_categories', array("fields" => "ids"));
$ccats = count($cats);
$vcats = array();
foreach($cats as $i => $cat)
{
    //apply slug & name as needed here  
    $vcats[$i] = '<a class="listing-links" href="/listing/' . $cat->slug . '" title="' . $cat->name . '">' . $cat->name . '</a>';
    if($i < ($ccats-1))
    {
        $vcats[$i] .= ',';
    }
}
array_splice($vcats, ($ccats-1), 0, array('and'));
echo 'Featured in ' . implode($vcats, ' ') . ' Collections';

希望能有所帮助
