我假设您正在使用Underocres starter主题来构建主题，您可能是从模板标记复制了代码。主题中的php inside inc文件夹。现在执行以下操作：

将此代码保存在模板标记中。php

function category_renown() {
    $categories = get_the_category_list( esc_html__( \' \', \'openblogger\' ));
    if ( $categories ) {
            printf( \'<span class="catu-links">\' . esc_html__( \'%1$s\', \'openblogger\' ) . \'</span>\', $categories ); // WPCS: XSS OK.
        }
}

在内容中复制函数。php文件，如：

这是内容对内容的内容。php文件

<?php
/**
 * Template part for displaying posts
 *
 * @link https://developer.wordpress.org/themes/basics/template-hierarchy/
 *
 * @package xyz
 */

?>

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
    <header class="entry-header">
        <?php category_renown(); ?>
        <?php
        if ( is_singular() ) :
            the_title( \'<h1 class="entry-title">\', \'</h1>\' );
        else :
            the_title( \'<h2 class="entry-title"><a href="\' . esc_url( get_permalink() ) . \'" rel="bookmark">\', \'</a></h2>\' );
        endif;

        if ( \'post\' === get_post_type() ) :
            ?>
            <div class="entry-meta">
                <?php
                xyz_posted_on();
                xyz_posted_by();
                ?>
            </div><!-- .entry-meta -->
        <?php endif; ?>
    </header><!-- .entry-header -->

    <?php xyz_post_thumbnail(); ?>

    <div class="entry-content">
        <?php
        the_content( sprintf(
            wp_kses(
                /* translators: %s: Name of current post. Only visible to screen readers */
                __( \'Continue reading<span class="screen-reader-text"> "%s"</span>\', \'xyz\' ),
                array(
                    \'span\' => array(
                        \'class\' => array(),
                    ),
                )
            ),
            get_the_title()
        ) );

        wp_link_pages( array(
            \'before\' => \'<div class="page-links">\' . esc_html__( \'Pages:\', \'xyz\' ),
            \'after\'  => \'</div>\',
        ) );
        ?>
    </div><!-- .entry-content -->

    <footer class="entry-footer">
        <?php xyz_entry_footer(); ?>
    </footer><!-- .entry-footer -->
</article><!-- #post-<?php the_ID(); ?> -->

现在需要删除模板标记中的以下代码。函数xyz\\u entry\\u footer（）中的php文件：

$categories = get_the_category_list( esc_html__( \' \', \'openblogger\' ));
if ( $categories ) {
        printf( \'<span class="catu-links">\' . esc_html__( \'%1$s\', \'openblogger\' ) . \'</span>\', $categories ); // WPCS: XSS OK.
    }

模板标签的最终版本。php应为：

<?php
/**
 * Custom template tags for this theme
 *
 * Eventually, some of the functionality here could be replaced by core features.
 *
 * @package xyz
 */

if ( ! function_exists( \'xyz_posted_on\' ) ) :

     */

        $time_string = \'<time class="entry-date published updated" datetime="%1$s">%2$s</time>\';
        if ( get_the_time( \'U\' ) !== get_the_modified_time( \'U\' ) ) {
            $time_string = \'<time class="entry-date published" datetime="%1$s">%2$s</time><time class="updated" datetime="%3$s">%4$s</time>\';
        }

        $time_string = sprintf( $time_string,

我只是假设您正在使用下划线起始主题构建主题。如果没有，请添加更多代码（在调用该函数的地方）

另一件事是，您可能对初学者主题做了更多更改，所以在复制和粘贴此代码之前要小心。
