将过滤器添加到 Wordpress 仪表板（不是帖子）

Question

我想在我们公司的项目管理站点的仪表板中筛选列表。我想按用户过滤，但目前 it can only sort by date. The users are displayed on hover so all of the information is there in the table, I just want to add a search bar to filter names. Is this relatively easily done? I am mostly front end so my php skills are somewhat lacking. The plugin being used is Panorma projects.

到目前为止我试过的所有插件都是用于过滤帖子的，它们不会转移到全景页面。

这是在 WP 自定义 Post 类型中添加自定义过滤器的代码。

只需根据您的要求更改代码即可。

在 select 框中的第一个函数中，按角色获取所有用户或特定用户。

并且在第二个函数中使用作者 ID

计算 selected 记录

 function wpse45436_admin_posts_filter_restrict_manage_posts(){
        $type = 'post';
        if (isset($_GET['post_type'])) {
            $type = $_GET['post_type'];
        }

        //only add filter to post type you want
        if ('POST_TYPE' == $type){
            //change this to the list of values you want to show
            //in 'label' => 'value' format
            $values = array(
                'label' => 'value', 
                'label1' => 'value1',
                'label2' => 'value2',
            );
            ?>
            <select name="ADMIN_FILTER_FIELD_VALUE">
            <option value=""><?php _e('Filter By ', 'wose45436'); ?></option>
            <?php
                $current_v = isset($_GET['ADMIN_FILTER_FIELD_VALUE'])? $_GET['ADMIN_FILTER_FIELD_VALUE']:'';
                foreach ($values as $label => $value) {
                    printf
                        (
                            '<option value="%s"%s>%s</option>',
                            $value,
                            $value == $current_v? ' selected="selected"':'',
                            $label
                        );
                    }
            ?>
            </select>
            <?php
        }
    }


    add_filter( 'parse_query', 'wpse45436_posts_filter' );
    /**
     * if submitted filter by post meta
     * 
     * make sure to change META_KEY to the actual meta key
     * and POST_TYPE to the name of your custom post type
     * @author Ohad Raz
     * @param  (wp_query object) $query
     * 
     * @return Void
     */
    function wpse45436_posts_filter( $query ){
        global $pagenow;
        $type = 'post';
        if (isset($_GET['post_type'])) {
            $type = $_GET['post_type'];
        }
        if ( 'POST_TYPE' == $type && is_admin() && $pagenow=='edit.php' && isset($_GET['ADMIN_FILTER_FIELD_VALUE']) && $_GET['ADMIN_FILTER_FIELD_VALUE'] != '') {
            $query->query_vars['author'] = ID of the user from $_GET;
        }
    }
