本地网址http://localhost/wordpress/wp-admin/post-new.php
进而找到post-new.php页面。
进入之后，
require_once( dirname( __FILE__ ) . '/admin.php' );//引入php
if ( !isset(GET[′posttype′]))post_type = 'post';
elseif ( in_array( GET[′posttype′],getposttypes(array(′showui′=>true))))post_type = $_GET['post_type'];
else
wp_die( __('Invalid post type') );//进行某种验证
posttypeobject=getposttypeobject(post_type );
if ( 'post' == posttype)$parentfile=′edit.php′;$submenufile=′post−new.php′;elseif(′attachment′==post_type ) {
if ( wp_redirect( admin_url( 'media-new.php' ) ) )
exit;
} else {
submenufile="post−new.php?posttype=post_type";
if ( isset( post_type_object ) &&post_type_object->show_in_menu && post_type_object->show_in_menu !== true ) {parent_file = posttypeobject−>showinmenu;if(!isset(_registered_pages[ get_plugin_page_hookname( "post-new.php?post_type=posttype",post_type_object->show_in_menu ) ] ) )
submenufile=parent_file;
} else {
parentfile="edit.php?posttype=post_type";
}
}//进行一些验证处理
title=post_type_object->labels->add_new_item;
$editing = true;
if ( ! current_user_can( posttypeobject−>cap−>editposts)||!currentusercan(post_type_object->cap->create_posts ) )
wp_die( __( 'Cheatin’ uh?' ) );
// Schedule auto-draft cleanup
if ( ! wp_next_scheduled( 'wp_scheduled_auto_draft_delete' ) )
wp_schedule_event( time(), 'daily', 'wp_scheduled_auto_draft_delete' );
wp_enqueue_script( 'autosave' );
if ( is_multisite() ) {
add_action( 'admin_footer', '_admin_notice_post_locked' );
} else {
$check_users = get_users( array( 'fields' => 'ID', 'number' => 2 ) );
if ( count( $check_users ) > 1 )
add_action( 'admin_footer', '_admin_notice_post_locked' );
unset( $check_users );
}//一些乱起八糟的操作，大概是验证吧
// Show post form.
post=getdefaultposttoedit(post_type, true );
postID=post->ID;
include( ABSPATH . 'wp-admin/edit-form-advanced.php' );
include( ABSPATH . 'wp-admin/admin-footer.php' );
这里加粗的代码式引入页面的，html页面都在这里面。第一个是主要内容，第二个是脚文件。
下面我们，走进wp-admin/edit-form-advanced.php下面看看究竟。
// don't load directly
if ( !defined('ABSPATH') )
die('-1');
wp_enqueue_script('post');
if ( wp_is_mobile() )
wp_enqueue_script( 'jquery-touch-punch' );//进行一些安全验证。很清晰。内容都在方法里。
$messages = array(); $messages['post'] = array( 0 => '', // Unused. Messages start at index 1. 1 => sprintf( __('Post updated. <a href="%s">View post</a>'), esc_url( get_permalink($post_ID) ) ), 2 => __('Custom field updated.'), 3 => __('Custom field deleted.'), 4 => __('Post updated.'), /* translators: %s: date and time of the revision */ 5 => isset($_GET['revision']) ? sprintf( __('Post restored to revision from %s'), wp_post_revision_title( (int) $_GET['revision'], false ) ) : false, 6 => sprintf( __('Post published. <a href="%s">View post</a>'), esc_url( get_permalink($post_ID) ) ), 7 => __('Post saved.'), 8 => sprintf( __('Post submitted. <a target="_blank" href="%s">Preview post</a>'), esc_url( add_query_arg( 'preview', 'true', get_permalink($post_ID) ) ) ), 9 => sprintf( __('Post scheduled for: <strong>%1$s</strong>. <a target="_blank" href="%2$s">Preview post</a>'), // translators: Publish box date format, see http://php.net/date date_i18n( __( 'M j, Y @ G:i' ), strtotime( $post->post_date ) ), esc_url( get_permalink($post_ID) ) ), 10 => sprintf( __('Post draft updated. <a target="_blank" href="%s">Preview post</a>'), esc_url( add_query_arg( 'preview', 'true', get_permalink($post_ID) ) ) ), ); $messages['page'] = array( 0 => '', // Unused.

点评：这里是一个信息，已数组的方式保存。貌似跑题了。
好了，看了那么多也不知道干什么的代码。
require_once( ABSPATH . 'wp-admin/admin-header.php' );
exit;//我在这里断了一下。
结果就看到了下面的界面。
这里貌似是导航吗。不错不错。继续往下看。
<?php screen_icon(); ?>//这个是图标展示的方法调用。

点评：一些隐藏的参数。
<?php wp_editor( $post->post_content, 'content', array( 'dfw' => true, 'tabfocus_elements' => 'insert-media-button,save-post', 'editor_height' => 360, ) ); ?>
//这段代码去除后，就看不到编辑框了。看来编辑框是用这个wp_editor方法写出来的。
<div id="postbox-container-1" class="postbox-container"> <?php if ( 'page' == $post_type ) { /** * Fires before meta boxes with 'side' context are output for the 'page' post type. * * The submitpage box is a meta box with 'side' context, so this hook fires just before it is output. * * @since 2.5.0 * * @param WP_Post $post Post object. */ do_action( 'submitpage_box', $post ); } else { /** * Fires before meta boxes with 'side' context are output for all post types other than 'page'. * * The submitpost box is a meta box with 'side' context, so this hook fires just before it is output. * * @since 2.5.0 * * @param WP_Post $post Post object. */ do_action( 'submitpost_box', $post ); } do_meta_boxes($post_type, 'side', $post); ?> </div>
//去除这个之后右边的编辑框就没有了
大概就是这样，里面的页面都是写在某些方法中了。
