wordpress分类目录添加自定义head内容
文章目录
head头部有很多代码都和seo有关，比如可以添加规范标签canonical、robots.txt标签等等。那么如何自定义在分类中添加head代码呢
代码
- //自定义添加head代码
- global $texonomy_slug_definedhead;
- $texonomy_slug_definedhead='category';
- add_action($texonomy_slug_definedhead.'_add_form_fields','categorydefinedhead');
- function categorydefinedhead($taxonomy){ ?>
- <div>
- <label for="tag-definedhead">自定义head</label>
- <input type="text" name="tag-definedhead" id="tag-definedhead" value="" /><br /><span>输入head代码</span>
- </div>
- <?php }
- add_action($texonomy_slug_definedhead.'_edit_form_fields','categorydefinedheadedit');
- function categorydefinedheadedit($taxonomy){ ?>
- <tr class="form-field">
- <th scope="row" valign="top"><label for="tag-definedhead">自定义head</label></th>
- <td><input type="text" name="tag-definedhead" id="tag-definedhead" value="<?php echo get_option('_category_definedhead'.$taxonomy->term_id); ?>" /><br /><span class="description">输入head代码</span></td>
- </tr>
- <?php }
- add_action('edit_term','categorydefinedheadsave');
- add_action('create_term','categorydefinedheadsave');
- function categorydefinedheadsave($term_id){
- if(isset($_POST['tag-definedhead'])){
- if(isset($_POST['tag-definedhead']))
- update_option('_category_definedhead'.$term_id,$_POST['tag-definedhead'] );
- }
- }
在函数模板上面的代码，添加一个字段
调用
- //
- 分类添加自定义head
- <?php
- if(is_category()){
- $title = the_zm_title();
- $category_info = get_the_category();
- $category_id = $category_info[0]->cat_ID;
- $cat_definedhead = get_option('_category_definedhead'.$category_id);
- ?>
- <?php echo $cat_definedhead;?>
- <?php } ?>
将代码放到header中使用即可
