WordPress后台的文章、分类，媒体，页面，评论,链接等所有信息中显示ID并将ID设置为第一列

WordPress后台默认是不显示文章、分类等信息ID的，查看起来非常不方便,不知道Wp团队出于什么原因默认不显示这个但可以使用Simply Show IDs插件来实现

 不使用插件,其他网友的实现：

<?php
/**
*为WordPress后台的文章、分类等显示ID From wpdaxue.com
* ID默认添加到列的后面
* http://www.wpdaxue.com/simply-show-ids.html
* htl add 2015-01-16
*/
//添加一个新的列 ID
function ssid_column($cols){
$cols['ssid']='ID';
return $cols;
}
//显示 ID
function ssid_value($column_name, $id){
if($column_name =='ssid')
echo $id;
}
function ssid_return_value($value, $column_name, $id){
if($column_name =='ssid')
$value = $id;
return $value;
}
//通过动作/过滤器输出各种表格和CSS
function ssid_add(){
add_filter('manage_posts_columns','ssid_column');
add_action('manage_posts_custom_column','ssid_value',10,2);
add_filter('manage_pages_columns','ssid_column');
add_action('manage_pages_custom_column','ssid_value',10,2);
add_filter('manage_media_columns','ssid_column');
add_action('manage_media_custom_column','ssid_value',10,2);
add_filter('manage_link-manager_columns','ssid_column');
add_action('manage_link_custom_column','ssid_value',10,2);
add_action('manage_edit-link-categories_columns','ssid_column');
add_filter('manage_link_categories_custom_column','ssid_return_value',10,3);
foreach ( get_taxonomies()as $taxonomy ){
add_action("manage_edit-${taxonomy}_columns",'ssid_column');
add_filter("manage_${taxonomy}_custom_column",'ssid_return_value',10,3);
}
add_action('manage_users_columns','ssid_column');
add_filter('manage_users_custom_column','ssid_return_value',10,3);
add_action('manage_edit-comments_columns','ssid_column');
add_action('manage_comments_custom_column','ssid_value',10,2);
}
add_action('admin_init','ssid_add');
?>

效果图：

/*

*/
function jue_post_id_column( $post_columns ){
$beginning = array_slice( $post_columns,0,1);
$beginning['postid']= __('ID','jue');
$ending = array_slice( $post_columns,1);
$post_columns = array_merge( $beginning, $ending );
return $post_columns;
}
add_filter('manage_posts_columns','jue_post_id_column');//添加文章列表页ID标题
add_filter('manage_pages_columns','jue_post_id_column');//添加页面列表页....
add_filter('manage_media_columns','jue_post_id_column');//添加多媒体列表页....
function jue_posts_id_column( $col, $val ){
if( $col =='postid') echo $val;
}
add_action('manage_posts_custom_column','jue_posts_id_column',10,2);//添加文章列表页ID列数值
add_action('manage_pages_custom_column','jue_posts_id_column',10,2);//添加页面列表页ID...
add_action('manage_media_custom_column','jue_posts_id_column',10,2);//添加多媒体列表页ID...
function jue_posts_id_column_css(){
echo '<style type="text/css">#postid {  50px; }</style>';//ID列宽度
}
add_action('admin_head-edit.php','jue_posts_id_column_css');

 

由于上面的两种都没有办法完全满足我的要求于是在上面两个的基础上进行了更改来实现我想要的效果

<?php
/**

 * 参考：http://www.wpdaxue.com/simply-show-ids.html
 *          http://www.zhugexiaojue.com/note/liveid-387.html
 * htl add 2015-01-16
 */
// 添加一个新的列 ID
function ssid_column($columns) {
    
    //将ID设置为第一列
    return array_merge(array('ssid' => 'ID'), $columns);
}
 
// 显示 ID
function ssid_value($column_name, $id) {
    if ($column_name == 'ssid')
        echo $id;
}
 
function ssid_return_value($value, $column_name, $id) {
    if ($column_name == 'ssid')
        $value = $id;
    return $value;
}
function ssid_css() {
    echo "<style>.column-ssid,#ssid{ 50px!important;text-align: center!important;padding: 0px!important;margin: 0px!important;}</style>";
}
 
// 通过动作/过滤器输出各种表格和CSS
function ssid_add() {
    add_action('admin_head', 'ssid_css');
 
    //文章
    add_filter('manage_posts_columns', 'ssid_column');
    add_action('manage_posts_custom_column', 'ssid_value', 10, 2);
    // 页面
    add_filter('manage_pages_columns', 'ssid_column');
    add_action('manage_pages_custom_column', 'ssid_value', 10, 2);
 
    // 媒体
    add_filter('manage_media_columns', 'ssid_column');
    add_action('manage_media_custom_column', 'ssid_value', 10, 2);
 
    // 连接
    add_filter('manage_link-manager_columns', 'ssid_column');
    add_action('manage_link_custom_column', 'ssid_value', 10, 2);
 
    // 连接分类
    add_action('manage_edit-link-categories_columns', 'ssid_column');
    add_filter('manage_link_categories_custom_column', 'ssid_return_value', 10, 3);
 
    foreach ( get_taxonomies() as $taxonomy ) {
        add_action("manage_edit-${taxonomy}_columns", 'ssid_column');            
        add_filter("manage_${taxonomy}_custom_column", 'ssid_return_value', 10, 3);
    }
 
    // 用户
    add_action('manage_users_columns', 'ssid_column');
    add_filter('manage_users_custom_column', 'ssid_return_value', 10, 3);
    // 评论
    add_action('manage_edit-comments_columns', 'ssid_column');
    add_action('manage_comments_custom_column', 'ssid_value', 10, 2);
}
 
add_action('admin_init', 'ssid_add');
?>

效果：
