Question

我正在尝试与div中的数据类别标记中的帖子关联的标记的回显列表。目前我的代码在标签中没有输出任何内容。我也有输出“阵列”这个词的地方。我需要显示为'tag1 tag2 etc'

以下是我目前在if have posts loop ...

中设置代码的方法

获得价值......

    $post_tag = wp_get_post_tags( $post_id, $args );

回应价值......

        <div data-category="<?php foreach($post_tag as $tag){ echo $tag; } ?>">

这是完整的代码......

    <?php $layout = get_post_type(); ?>

    <?

    $slug = get_post( $post )->post_name;
    $post_tag = wp_get_post_tags( $post_id, $args );


    ?>

    <? if ( $layout == 'fullscreenimage' ){ ?>


    <p>layout 1</p>

        <div class="portfolio-item" data-id="<?php echo $slug; ?>" data-category="<?php foreach($post_tag as $tag){ echo $tag; } ?>">

            <h1 class="entry-title"><?php the_title(); ?></h1>

        </div>

    <?php } elseif ( $layout == 'singleimagetext' ) {  ?>

        <p>layout 2</p>

        <div class="portfolio-item" data-id="<?php echo $slug; ?>" data-category="<? //echo $tags; ?>">

            <h1 class="entry-title"><?php the_title(); ?></h1>

        </div>

    <?php } elseif ( $layout == 'casestudy' ) {  ?>

        <p>layout 3</p>

        <div class="portfolio-item" data-id="<?php echo $slug; ?>" data-category="<? //echo $tags; ?>">

            <h1 class="entry-title"><?php the_title(); ?></h1>

        </div>

    <?php } elseif ( $layout == 'gallery' ) {  ?>

        <p>layout 4</p>

        <div class="portfolio-item" data-id="<?php echo $slug; ?>" data-category="<? //echo $tags; ?>">

            <h1 class="entry-title"><?php the_title(); ?></h1>

        </div>


    <?php } ?>

<?php endwhile; ?>

<?php else : ?>

    <h2 class=”center”>Not Found</h2>
    <p class=”center”>Sorry, but you are looking for something that isn’t here.</p>

<?php endif; ?>
<?php /* end my loop */ ?>

Answer 1

$ tag是std Class的一个对象，根据文档，为了得到标签名称，试试这个

<div data-category="<?php foreach($post_tag as $tag){ echo $tag->name; } ?>">

$ tag-＆gt; name只是获取名为name的stdClass Object属性。

这是对象返回的内容，因此您可以获取URL的term_id或slug等其他信息。

 stdClass Object
       (
           [term_id] => 4
           [name] => tag2
           [slug] => tag2
           [term_group] => 0
           [term_taxonomy_id] => 4
           [taxonomy] => post_tag
           [description] => 
           [parent] => 0
           [count] => 7
       )

文档wp get post tags

Answer 2

为functions.php添加了一个函数

function my_post_terms() {

// Get an array of all taxonomies for this post
$taxonomies = get_taxonomies( '', 'names' );

// Are there any taxonomies to get terms from?
if ( $taxonomies ) {    

    // Call the wp_get_post_terms function to retrieve all terms. It accepts an array of taxonomies as argument. 
    $arr_terms = wp_get_post_terms( get_the_ID(), array_values( $taxonomies ) , array( "fields" => "names" ) );

    // Convert the terms array to a string
    $terms = implode( ' ',$arr_terms );

    // Get out of here
    return $terms;
}
}

然后添加了这个echo my_post_terms（）;在HTML ...

<div class="portfolio-item" data-id="<?php echo $slug; ?>" data-category="<?php echo my_post_terms(); ?>">
