在上文中我们成功添加了Shortcodes短代码，然而在编辑的时候还是有点不方便，为了更有效率的进行文章编辑，我们还可以给WordPress的后台编辑器加上自定义按钮
添加HTML文本编辑器下的按钮
WordPress后台默认使用的是TinyMCE编辑器，Github地址。后台的按钮大致分为三种，最上方的我称作Media button，默认只有一个添加媒体按钮，在可视化编辑器下的的叫Edit button，这些按钮可以自己添加图片（标），最后在HTML文本编辑器下的叫HTML button
此处添加的是文本按钮添加添加文本编辑器的按钮方法比较简单，只需用到一个action钩子，还是打开主题的functions.php，加在最后一个?>之前（一般在add_action，add_fliter这些后面一点点都OK）前提是已经添加好Shortcode，代码示例
|
1 2 3 4 5 6 7 8 9 10 |
add_action('after_wp_tiny_mce', 'add_html_button'); function add_html_button($mce_settings) { ?> <script type="text/javascript"> QTags.addButton( '红标题', '红标题', "[hongbt]", "[/hongbt]" ); QTags.addButton( '红高亮', '红高亮', "[hong]", "[/hong]" ); QTags.addButton( '键盘', '键盘', "[kbd]", "[/kbd]" ); </script> <?php } |
添加可视化编辑器按钮
functions.php中添加的代码参考
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
add_filter( 'mce_external_plugins', 'add_plugin' ); add_filter( 'mce_buttons', 'register_button' ); function register_button( $buttons ) { array_push( $buttons, " ", "maclight" ); array_push( $buttons, " ", "showmore" ); array_push( $buttons, " ", "btnblue" ); return $buttons; } function add_plugin( $plugin_array ) { $plugin_array['maclight'] = get_bloginfo( 'template_url' ) . '/shortcodes/more.js'; $plugin_array['showmore'] = get_bloginfo( 'template_url' ) . '/shortcodes/more.js'; $plugin_array['btnblue'] = get_bloginfo( 'template_url' ) . '/shortcodes/more.js'; return $plugin_array; } |
接下来在新建一个名为shortcodes的文件夹，上传到主题根目录，里面新建一个more.js的文件，编辑该文件，参考代码
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
(function() { tinymce.create('tinymce.plugins.maclight', { init : function(ed, url) { ed.addButton('maclight', { title : 'Mac白色标题', image : url+'/images/maclight.png', onclick : function() { ed.selection.setContent('[maclight title="标题"]内容' + ed.selection.getContent() + '[/maclight]'); } }); }, createControl : function(n, cm) { return null; }, }); tinymce.PluginManager.add('maclight', tinymce.plugins.maclight); tinymce.create('tinymce.plugins.btnblue', { init : function(ed, url) { ed.addButton('btnblue', { title : '蓝色按钮', image : url+'/images/btnblue.png', onclick : function() { ed.selection.setContent('[btnblue title="链接（已加http头）"]标题' + ed.selection.getContent() + '[/btnblue]'); } }); }, createControl : function(n, cm) { return null; }, }); tinymce.PluginManager.add('btnblue', tinymce.plugins.btnblue); })(); |
变量名需和functions.php里的一致，可以看到我需要在shortcodes文件夹下新建一个叫images的文件夹，里面存放按钮的图片，我设置的是方形的200*200的png图片
添加Media button
Media button的添加我在网上并没有找到任何教程（或者有教程也是错误的），目前只会添加按钮但还不能给按钮赋值，实现更多的功能，说不定以后多参考几个插件的代码可以找到方法
|
1 2 3 4 |
add_action('media_buttons', 'add_media_button'); function add_media_button() { echo '<a id="insert-my-media" class="button" href="#">媒体按钮</a>'; } |

Hiya! I know this is kinda off topic nevertheless I'd
figured I'd ask. Would you be interested in trading links or maybe guest authoring a blog article or vice-versa?
My blog discusses a lot of the same topics as yours and I think we could greatly benefit from
