WordPress如何为Post->ID摘录过滤器添加TinyMCE格式行功能 - WordPress how to add TinyMCE format row function to Post->ID Excerpt filter

我使用强制摘录代码来自动生成摘录内容，而不使用more标记或摘录编辑框，如下所示:

function mytheme_excerpt_read_more_link( $output ) {
  global $post;
  return $output . ' <div class="more-link">
  <a href="' . get_permalink( $post->ID ) . '>Read More</a></div>';
  }
add_filter( 'the_excerpt', 'mytheme_excerpt_read_more_link' );

但是，我需要添加TinyMCE函数，以便如果有人在编辑器中添加斜体(例如)，<em>将在摘录代码中拾取。

这是我自定义TinyMCE的内容:

add_filter( 'mce_buttons', 'mrw_mce_buttons_1' );
  function mrw_mce_buttons_1( $buttons ) {
  $buttons = array('styleselect', 'bold', 'italic', 
  'link', 'unlink', 'bullist', 'numlist', 'indent', 
  'outdent', 'pastetext', 'removeformat', 'charmap', 
  'undo', 'redo',  'wp_more','wp_help',  );
return $buttons;
}

如何将上述过滤器添加到Post->ID?我试过这个，但它没有工作:

 function my_theme_add_tinymce_styles() {
    global $post;
    $post_type = get_post_type( $post->ID );
    $tinymce_style = 'mrw_mce_buttons_1';
    add_editor_style( $tinymce_style );
    }
add_action( 'pre_get_posts', 'my_theme_add_tinymce_styles' );

谢谢查尔斯。

这将把编辑器窗口中的tinyMCE设置放在摘录窗口中:

<?php
//adjust Excerpt box height
function admin_excerpt() { echo "<style>"; echo "textarea#excerpt {height:300px;}"; echo "</style>"; } add_action('admin_head', 'admin_excerpt');

Code to adding the TinyMCE visual editor to an excerpt is from:

Code 1.
To me this seems like the best code of the 3 to use. */
