在主题中，我使用customizer显示帖子之前（和之后）的内容、单个帖子等。

/**
Page Before Category
*/
$wp_customize->add_setting( \'content_before_category\', array(
    \'default\'           => 0,
    \'sanitize_callback\' => \'theme_name_sanitize_integer\',
) );
$wp_customize->add_control( \'content_before_category\', array(
    \'label\'       => esc_html__( \'Page Before Category\', \'theme_name\' ),
    \'description\' => esc_html__( \'Content of the selected page will be shown on Blog Page before all posts.\', \'theme_name\' ),
    \'type\'        => \'dropdown-pages\',
    \'section\'     => \'section_blog\',
) );

然后在index.php 我用过

$content_before_category = get_theme_mod( \'content_before_category\', false );

if ( $content_before_category ) {
    $page_id = get_page( $content_before_category );
    echo apply_filters( \'the_content\', $page_id->post_content ); // WPCS: xss ok.
}

但有人告诉我the_content 直接过滤是不好的，因为它可能会破坏插件as described here.

因此，我做了以下工作：

在我的functions.php 我补充道

if ( ! function_exists( \'mytheme_content_filter\' ) ) {
    /**
     * Default content filter
     *
     * @param  string $content Post content.
     * @return string          Post content.
     */
    function mytheme_content_filter( $content ) {
        return $content;
    }
}

/**
 * Adds custom filter that filters the content and is used instead of \'the_content\' filter.
 */
add_filter( \'mytheme_content_filter\', \'wptexturize\' );
add_filter( \'mytheme_content_filter\', \'convert_smilies\' );
add_filter( \'mytheme_content_filter\', \'convert_chars\' );
add_filter( \'mytheme_content_filter\', \'wpautop\' );
add_filter( \'mytheme_content_filter\', \'shortcode_unautop\' );
add_filter( \'mytheme_content_filter\', \'do_shortcode\' );

然后将过滤器更改为

$content_before_category = get_theme_mod( \'content_before_category\', false );

if ( $content_before_category ) {
    $page_id = get_page( $content_before_category );
    echo apply_filters( \'mytheme_content_filter\', $page_id->post_content ); // WPCS: xss ok.
}

它适用于除嵌入式内容以外的所有内容。

youtube视频、推特将无法正常呈现。

我尝试搜索嵌入筛选器，但找不到。

有什么建议吗？

$content_before_category = get_theme_mod( \'content_before_category\', false );

if ( $content_before_category ) {

    global $post;

    // get_page() is deprecated; use get_post() instead
    // $page_id = get_page( $content_before_category );
    $post = get_post( $content_before_category );

    // Setup global post data with our page
    setup_postdata( $post );

    // Output the content
    the_content();

    // Reset global post data
    wp_reset_postdata();

}

global $wp_embed;
add_filter( \'mytheme_content_filter\', array( $wp_embed, \'autoembed\') );
