Twenty Fifteen主题首页摘要显示方法

Twenty Fifteen主题首页摘要显示方法一

我们知道，在搜索结果中文章是以摘要的形式显示的，因此在index.php中找到以下代码

1. 
   <?php
   
2. // Start the loop.
3. while ( have_posts() ) : the_post();
   
4. /*
5. * Include the Post-Format-specific template for the content.
6. * If you want to override this in a child theme, then include a file
7. * called content-___.php (where ___ is the Post Format name) and that will be used instead.
8. */
9. 
   get_template_part( 'content', get_post_format() );
   
11. // End the loop.
12. endwhile;
    

更改为以下代码。只是把content改为了content-search。

1. 
   <?php
   
2. // Start the loop.
3. while ( have_posts() ) : the_post();
   
5. /*
6. * Include the Post-Format-specific template for the content.
7. * If you want to override this in a child theme, then include a file
8. * called content-___.php (where ___ is the Post Format name) and that will be used instead.
9. */
10. 
    get_template_part( 'content-search', get_post_format() );
    
12. // End the loop.
13. endwhile;
    

好了，刷新一下首页就可以看到结果了。

twentyfifteen主题首页摘要显示方法二

twentyfifteen首页摘要显示方法二是修改content.php文件。先看看content.php以下部分

1. 
   <div class="entry-content">
   
2. 
   <?php
   
3. /* translators: %s: Name of current post */
4. 
   the_content( sprintf(
   
5. 
   __( 'Continue reading %s', 'twentyfifteen' ),
   
6. 
   the_title( '<span class="screen-reader-text">', '</span>', false )
   
7. 
   ) );
   
9. 
   wp_link_pages( array(
   
10. 
    'before'      => '<div class="page-links"><span class="page-links-title">' . __( 'Pages:', 'twentyfifteen' ) . '</span>',
    
11. 
    'after'       => '</div>',
    
12. 
    'link_before' => '<span>',
    
13. 
    'link_after'  => '</span>',
    
14. 
    'pagelink'    => '<span class="screen-reader-text">' . __( 'Page', 'twentyfifteen' ) . ' </span>%',
    
15. 
    'separator'   => '<span class="screen-reader-text">, </span>',
    
16. 
    ) );
    
17. 
    ?>
    
18. 
    </div><!-- .entry-content-–>
    

修改成以下代码形式，也就是说除了文章内页以外，全部以摘要的方法显示。

1. 
   <div class="entry-content">
   
2. 
   <?php
   
3. if ( is_single() ) :
   
4. /* translators: %s: Name of current post */
5. 
   the_content( sprintf(
   
6. 
   __( 'Continue reading %s', 'twentyfifteen' ),
   
7. 
   the_title( '<span class="screen-reader-text">', '</span>', false )
   
8. 
   ) );
   
10. 
    wp_link_pages( array(
    
11. 
    'before'      => '<div class="page-links"><span class="page-links-title">' . __( 'Pages:', 'twentyfifteen' ) . '</span>',
    
12. 
    'after'       => '</div>',
    
13. 
    'link_before' => '<span>',
    
14. 
    'link_after'  => '</span>',
    
15. 
    'pagelink'    => '<span class="screen-reader-text">' . __( 'Page', 'twentyfifteen' ) . ' </span>%',
    
16. 
    'separator'   => '<span class="screen-reader-text">, </span>',
    
17. 
    ) );
    
18. else :
    
20. /* translators: %s: Name of current post */
21. 
    the_excerpt( sprintf(
    
22. 
    __( 'Continue reading %s', 'twentyfifteen' ),
    
23. 
    the_title( '<span class="screen-reader-text">', '</span>', false )
    
24. 
    ) );
    
26. 
    wp_link_pages( array(
    
27. 
    'before'      => '<div class="page-links"><span class="page-links-title">' . __( 'Pages:', 'twentyfifteen' ) . '</span>',
    
28. 
    'after'       => '</div>',
    
29. 
    'link_before' => '<span>',
    
30. 
    'link_after'  => '</span>',
    
31. 
    'pagelink'    => '<span class="screen-reader-text">' . __( 'Page', 'twentyfifteen' ) . ' </span>%',
    
32. 
    'separator'   => '<span class="screen-reader-text">, </span>',
    
33. 
    ) );
    
34. endif;
    
36. 
    ?>
    
37. 
    </div><!-- .entry-content-–>
    

twentyfifteen主题更改摘要字数

虽然经过上面的修改，twentyfifteen主题是以摘要的方法显示了，但是摘要字数并不满意，字数太少。我们可以通过修改functions.php文件来修改摘要显示的字数。找到以下代码

1. function twentyfifteen_search_form_modify( $html ) {
   
2. return str_replace( 'class="search-submit"', 'class="search-submit screen-reader-text"', $html );
   
3. 
   }
   
4. 
   add_filter( 'get_search_form', 'twentyfifteen_search_form_modify' );
   

在其后面加上如下代码。200是摘要所显示的字符数。

1. function twenty_fifteen_excerpt_length( $length ) {
   
2. return 200;
   
3. 
   }
   
4. 
   add_filter( 'excerpt_length', 'twenty_fifteen_excerpt_length', 999 );
