如何在每个帖子的开头和结尾放置特定文本？

Question

我目前正在使用此代码，它显示了每个帖子的代码开头。我想在每篇文章的开头和结尾显示代码。有人能帮忙吗？add_filter( 'the_content', 'filter_the_content_in_the_main_loop' );function filter_the_content_in_the_main_loop( $content ) {    // Check if we're inside the main loop in a single post page.    if ( is_single() && in_the_loop() && is_main_query() ) {       return esc_html__("So Friends, How is our Article of ".get_the_title().".

你已经知道答案了。在“the_content”过滤器中，您将一些文本添加到 $content 变量中。现在你想要做的是追加。前任：

add_filter( 'the_content', 'filter_the_content_in_the_main_loop' );

function filter_the_content_in_the_main_loop( $content ) {

    // Check if we're inside the main loop in a single post page.

    if ( is_single() && in_the_loop() && is_main_query() ) {

       return "Beginning text" .$content . "Ending Text";

    }

    return $content;

}

“开始文本”是您已经添加的文本。

add_filter( 'the_content', 'filter_the_content_in_the_main_loop' );

function filter_the_content_in_the_main_loop( $content ) {

    // Check if we're inside the main loop in a single post page.

    if ( is_single() && in_the_loop() && is_main_query() ) {

    //get categories

        $categories = get_the_category();

        foreach($categories as $category){

            //you can check by term_id, name, slug

            if($category->$term_id == $target_term_id){

                return "Beginning text" .$content . "Ending Text";

            }

        }

    }

    return $content;
