我从来没见过在自定义面板添加编辑器的应用，直到昨天一个网友说有这个需求，但是我昨天尝试了一下没成功，原因是太晚了，脑袋不清醒，函数都没写完整。
好了废话不多说，怎样在WordPress的自定义面板中添加一个可视化的编辑器呢？我们还是沿用上一篇教程中的测试文件，直接在该文件中添加一项。
首先打开我们的metabox.PHP文件，在配置数组中添加一项：
"checkbox" => array( "name" => "_meta_eidtor", "std" => '', "title" => "编辑器", "type"=>"editor"), case 'editor': echo'<h4>'.$meta_box['title'].'</h4>'; wp_editor( $meta_box['std'], $meta_box['name'].'_value' ); //带配置参数 /*wp_editor($meta_box['std'],$meta_box['name'].'_value', $settings = array(quicktags=>0,//取消HTML模式 tinymce=>1,//可视化模式 media_buttons=>0,//取消媒体上传 textarea_rows=>5,//行数设为5 editor_class=>"textareastyle") ); */ break; <?php $new_meta_boxes = array( "title" => array( "name" => "_meta_title", "std" => "", "title" => "标题", "type"=>"title"), "keywords" => array( "name" => "_meta_keywords", "std" => "", "title" => "关键字", "type"=>"text"), "description" => array( "name" => "_meta_description", "std" => "", "title" => "描述", "type"=>"textarea"), "category" => array( "name" => "_meta_cate", "std" => "", "title" => "选择分类", "subtype"=> "cat", "type"=>"dropdown"), "radio" => array( "name" => "_meta_radio", "std" => 1, "title" => "单选框", "buttons" => array('Yes','No'), "type"=>"radio"), "checkbox" => array( "name" => "_meta_checkbox", "std" => 1, "title" => "复选框", "type"=>"checkbox"), "checkbox" => array( "name" => "_meta_eidtor", "std" => '', "title" => "编辑器", "type"=>"editor"), ); function new_meta_boxes() { global $post, $new_meta_boxes; foreach($new_meta_boxes as $meta_box) { //获取保存的是 $meta_box_value = get_post_meta($post->ID, $meta_box['name'].'_value', true); if($meta_box_value != "") $meta_box['std'] = $meta_box_value;//将默认值替换为以保存的值 echo'<input type="hidden" name="'.$meta_box['name'].'_noncename" id="'.$meta_box['name'].'_noncename" value="'.wp_create_nonce( plugin_basename(__FILE__) ).'" />'; //通过选择类型输出不同的html代码 switch ( $meta_box['type'] ){ case 'title': echo'<h4>'.$meta_box['title'].'</h4>'; break; case 'text': echo'<h4>'.$meta_box['title'].'</h4>'; echo '<input type="text" size="40" name="'.$meta_box['name'].'_value" value="'.$meta_box['std'].'" /><br />'; break; case 'textarea': echo'<h4>'.$meta_box['title'].'</h4>'; echo '<textarea cols="60" rows="3" name="'.$meta_box['name'].'_value">'.$meta_box['std'].'</textarea><br />'; break; case 'dropdown': echo'<h4>'.$meta_box['title'].'</h4>'; if($meta_box['subtype'] == 'cat'){ $select = 'Select category'; $entries = get_categories('title_li=&orderby=name&hide_empty=0');//获取分类 } echo '<p><select name="'.$meta_box['name'].'_value"> '; echo '<option value="">'.$select .'</option> '; foreach ($entries as $key => $entry){ $id = $entry->term_id; $title = $entry->name; if ( $meta_box['std'] == $id ){ $selected = "selected='selected'"; }else{ $selected = ""; } echo "<option $selected value='". $id."'>". $title."</option>"; } echo '</select><br />'; break; case 'radio': echo'<h4>'.$meta_box['title'].'</h4>'; $counter = 1; foreach( $meta_box['buttons'] as $radiobutton ) { $checked =""; if(isset($meta_box['std']) && $meta_box['std'] == $counter) { $checked = 'checked = "checked"'; } echo '<input '.$checked.' type="radio" class="kcheck" value="'.$counter.'" name="'.$meta_box['name'].'_value"/>'.$radiobutton; $counter++; } break; case 'checkbox': echo'<h4>'.$meta_box['title'].'</h4>'; if( isset($meta_box['std']) && $meta_box['std'] == 'true' ) $checked = 'checked = "checked"'; else $checked = ''; echo '<input type="checkbox" name="'.$meta_box['name'].'_value" value="true" '.$checked.' />'; break; //编辑器 case 'editor': echo'<h4>'.$meta_box['title'].'</h4>'; wp_editor( $meta_box['std'], $meta_box['name'].'_value' ); //带配置参数 /*wp_editor($meta_box['std'],$meta_box['name'].'_value', $settings = array(quicktags=>0,//取消html模式 tinymce=>1,//可视化模式 media_buttons=>0,//取消媒体上传 textarea_rows=>5,//行数设为5 editor_class=>"textareastyle") ); */ break; } } } function create_meta_box() { global $theme_name; if ( function_exists('add_meta_box') ) { add_meta_box( 'new-meta-boxes', '自定义模块', 'new_meta_boxes', 'post', 'normal', 'high' ); } } function save_postdata( $post_id ) { global $post, $new_meta_boxes; foreach($new_meta_boxes as $meta_box) { if ( !wp_verify_nonce( $_POST[$meta_box['name'].'_noncename'], plugin_basename(__FILE__) )) { return $post_id; } if ( 'page' == $_POST['post_type'] ) { if ( !current_user_can( 'edit_page', $post_id )) return $post_id; } else { if ( !current_user_can( 'edit_post', $post_id )) return $post_id; } $data = $_POST[$meta_box['name'].'_value']; if(get_post_meta($post_id, $meta_box['name'].'_value') == "") add_post_meta($post_id, $meta_box['name'].'_value', $data, true); elseif($data != get_post_meta($post_id, $meta_box['name'].'_value', true)) update_post_meta($post_id, $meta_box['name'].'_value', $data); elseif($data == "") delete_post_meta($post_id, $meta_box['name'].'_value', get_post_meta($post_id, $meta_box['name'].'_value', true)); } } add_action('admin_menu', 'create_meta_box'); add_action('save_post', 'save_postdata'); ?> $ashu_eidtor = get_post_meta($post->ID, "_meta_eidtor_value", true); $ashu_editor = get_post_meta($post->ID, "_meta_eidtor_value", true); $ashu_editor = apply_filters('the_content', $ashu_editor); $ashu_editor = str_replace(']]>', ']]>', $ashu_editor); echo $ashu_editor;
接下来我们只需要改动显示的函数new_meta_boxes，在它的switch语句中添加一项即可：
"checkbox" => array( "name" => "_meta_eidtor", "std" => '', "title" => "编辑器", "type"=>"editor"), case 'editor': echo'<h4>'.$meta_box['title'].'</h4>'; wp_editor( $meta_box['std'], $meta_box['name'].'_value' );

*/ break; <?php $new_meta_boxes = array( "title" => array( "name" => "_meta_title", "std" => "", "title" => "标题", "type"=>"title"), "keywords" => array( "name" => "_meta_keywords", "std" => "", "title" => "关键字", "type"=>"text"), "description" => array( "name" => "_meta_description", "std" => "", "title" => "描述", "type"=>"textarea"), "category" => array( "name" => "_meta_cate", "std" => "", "title" => "选择分类", "subtype"=> "cat", "type"=>"dropdown"), "radio" => array( "name" => "_meta_radio", "std" => 1, "title" => "单选框", "buttons" => array('Yes','No'), "type"=>"radio"), "checkbox" => array( "name" => "_meta_checkbox", "std" => 1, "title" => "复选框", "type"=>"checkbox"), "checkbox" => array( "name" => "_meta_eidtor", "std" => '', "title" => "编辑器", "type"=>"editor"), ); function new_meta_boxes() { global $post, $new_meta_boxes; foreach($new_meta_boxes as $meta_box) { //获取保存的是 $meta_box_value = get_post_meta($post->ID, $meta_box['name'].'_value', true); if($meta_box_value != "") $meta_box['std'] = $meta_box_value;//将默认值替换为以保存的值 echo'<input type="hidden" name="'.$meta_box['name'].'_noncename" id="'.$meta_box['name'].'_noncename" value="'.wp_create_nonce( plugin_basename(__FILE__) ).'" />';

*/ break; } } } function create_meta_box() { global $theme_name; if ( function_exists('add_meta_box') ) { add_meta_box( 'new-meta-boxes', '自定义模块', 'new_meta_boxes', 'post', 'normal', 'high' ); } } function save_postdata( $post_id ) { global $post, $new_meta_boxes;

} else { if ( !current_user_can( 'edit_post', $post_id )) return $post_id; } $data = $_POST[$meta_box['name'].'_value']; if(get_post_meta($post_id, $meta_box['name'].'_value') == "") add_post_meta($post_id, $meta_box['name'].'_value', $data, true);

其实调用编辑器很简单，只需要使用wp_editor函数即可。
效果图：
至此，为了方便很多不愿意折腾的访客，我们直接贴出到现在为止的整个metabox.php文件的代码，你只需要在主题中加载这个文件即可，至于怎么配置，我想无需多说。
"checkbox" => array( "name" => "_meta_eidtor", "std" => '', "title" => "编辑器", "type"=>"editor"), case 'editor': echo'<h4>'.$meta_box['title'].'</h4>'; wp_editor( $meta_box['std'], $meta_box['name'].'_value' );

调用，使用get_post_meta函数获取即可，不过主要我们保存的字段名称，虽然我们的配置数组中配置了name，但是保存自定义字段的时候我们在字段名称后面加了_value，以我们今天新增的_meta_eidtor为例，获取应该是：
"checkbox" => array( "name" => "_meta_eidtor", "std" => '', "title" => "编辑器", "type"=>"editor"), case 'editor': echo'<h4>'.$meta_box['title'].'</h4>'; wp_editor( $meta_box['std'], $meta_box['name'].'_value' );

如何像普通文章一样输出？也就是自动加<p>标签和换行？如下：
"checkbox" => array( "name" => "_meta_eidtor", "std" => '', "title" => "编辑器", "type"=>"editor"), case 'editor': echo'<h4>'.$meta_box['title'].'</h4>'; wp_editor( $meta_box['std'], $meta_box['name'].'_value' );
