WordPress说是一个CMS系统，其实意义还是比较传统的看法，其实WordPress能做的东西是越来越多，如我用其做过下载、企业、个人博客、多用户博客、自媒体、商城、外贸等各类形式的站点。

在我看来WordPress更像是一个介于面对后端开发人员的开发框架和面对前端开发人员模板引擎之间的一个系统。只要会jQuery、JavaScript、CSS、html和简单的PHP判断语言，利用函数即可非常容易的写出WordPress主题。

wordpress子主题：如何覆盖模板.php文件
我在wordpress中设置了子主题, 并且子主题中的style.css和functions.php正常工作。我现在想用子主题中的版本覆盖其他模板.php文件。我似乎无法使这些文件覆盖父主题。
子主题functions.php：
```
<?php
//enqueue styles
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles', 'overwrite' );
function theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
//overwrite template pages
function overwrite() {
    wp_enqueue_script( get_template_directory_uri() . '/inc/structure/hooks.php' );
    wp_enqueue_script( get_template_directory_uri() . '/inc/structure/header.php' );
}
```
我在/ child-theme / inc / structure /中有一个hooks.php和header.php
对于子主题, 你无需排队任何模板(PHP)文件, 只需将一个PHP文件添加到你的子主题中, 其名称和路径与你试图覆盖父主题的名称和路径完全相同, 它将自然地替换它。

WordPress 插件开发激活插件时添加通知代码实例

最近我们在重构WordPress采集插件WP-JPost，这里记录一下当我们激活插件时在面板中添加通知的方法。

使用场景

我们插件使用register_post_type方法来构建了自定义文章（wordpress使用register_post_type 函数创建自定义文章类型）后出现了404的错误。这里我们使用添加通知的方法来告知用户必须设置一下【固定链接】（WordPress 固定链接设置）才能正常使用。下面我们记录一下具体的实现方法。

添加通知方法

可以通过admin_notices的add_action来实现。

		add_action( 'admin_notices', array( $this, 'jpost_notice' ) );

实现方法函数

做好输出工作即可。

	public function jpost_notice(){
		if( get_post_type() == $this->post_type )
			printf('<div class="jads"></div>');
		/* Check transient, if available display notice */
		if (! get_option('permalink_structure') ){
			printf('<div class="updated notice notice-warning is-dismissible">');
			printf('<p>%s</p>', __( 'WP-JPost need Navigate to [ <strong>Dashboard</strong> ] -> [ <strong>Settings</strong> ] -> [ <strong>Permalink</strong> ] page -> click [ <strong>Save</strong> ] button to flush rewrite rules. [ <a href="https://www.jiloc.com/44235.html">?</a> ]') );
			printf('</div>');
			/* Delete transient, only display this notice once. */
			// delete_transient( 'jpost-notice' );
		}
	}

激活插件事件

当没有设置固定链接的时候输出 jpost-notice 的通知。

	static function active() {
		if (! get_option('permalink_structure') )
			set_transient( 'jpost-notice', true );
		flush_rewrite_rules();
	}

全部代码

//register activation function
register_activation_hook( __FILE__, array( 'WP_JPost', 'active') );
//register deactivation function
register_deactivation_hook( __FILE__ , array( 'WP_JPost', 'deactive') );
class WP_JPost {
	protected $jpost_readme = 'https://www.jiloc.com/wp-jpost';
	protected $post_type = 'wp-jpost';
	protected $rewrite_slug = 'jpost';
	/**
	 * Constructor.
	 */
	public function __construct() {
                add_action( 'plugins_loaded', array( $this, 'load_textdomain' ) );
		add_action( 'init', array( $this, 'register_post_type' ) );
		// add_filter( 'post_type_link', array($this , 'custom_link' ), 1, 3);
		add_filter( 'query_vars', array( $this, 'jpost_query_vars') );
		add_filter( 'post_updated_messages', array( $this, 'updated_message' ) );
		// add_action( 'admin_init',array($this,'register_setting_page'));
		add_action( 'admin_menu', array( $this, 'add_meta_box' ) );
		add_action( 'save_post', array( $this, 'meta_box_save' ), 1, 2 );
		add_action( 'manage_wp-jpost_posts_custom_column', array( $this, 'columns_data' ) );
		add_filter( 'manage_wp-jpost_posts_columns', array( $this, 'columns_filter' ) );
		add_action( 'template_redirect', array( $this, 'jpost_grab' ) );
		add_action( 'admin_notices', array( $this, 'jpost_notice' ) );
	}
	
	public function custom_link( $permalink, $post ){
		if ( $post->post_type == $this->post_type ){
			return $permalink . ( strpos( $permalink ,'?' ) !== false ? '&' : '?') . 'jpage='.get_post_meta( get_the_ID(), '_jpost_task_list_max_page', true ) . '&debug=1';
		} else {
			return $permalink;
		}
	}
	public function jpost_notice(){
		if( get_post_type() == $this->post_type )
			printf('<div class="jads"></div>');
		/* Check transient, if available display notice */
		if (! get_option('permalink_structure') ){
			printf('<div class="updated notice notice-warning is-dismissible">');
			printf('<p>%s</p>', __( 'WP-JPost need Navigate to [ <strong>Dashboard</strong> ] -> [ <strong>Settings</strong> ] -> [ <strong>Permalink</strong> ] page -> click [ <strong>Save</strong> ] button to flush rewrite rules. [ <a href="https://www.jiloc.com/44235.html">?</a> ]') );
			printf('</div>');
			/* Delete transient, only display this notice once. */
			// delete_transient( 'jpost-notice' );
		}
	}
	static function active() {
		if (! get_option('permalink_structure') )
			set_transient( 'jpost-notice', true );
		flush_rewrite_rules();
	}
}

WordPress插件开发 register_post_type 设定菜单位置结合 add_submenu_page 添加自定义设置页面

前面我们讲述了利用 register_post_type 进行注册了自定义的文章（wordpress使用register_post_type 函数创建自定义文章类型）, 然后我们为这个自定义的文章添加了自定义的设置页面。要把菜单放在一个栏目中。如下图所示：

下面我们直接给出示例代码。

plugin.php 设置前后台使用不同的类

require_once JPOST_DIR . '/includes/class-wp-jpost.php';
new WP_JPost();
if ( is_admin() ) {
	require_once JPOST_DIR . '/includes/class-wp-jpost-settings.php';
	new JPostSettings();
}

WP_JPost 类

在 admin_menu 钩子中添加add_meta_box

 add_action( 'admin_menu', array( $this, 'add_meta_box' ) );

add_meta_box 里添加菜单

	public function add_meta_box() {
		add_menu_page( 'wp_jpost', 'wp-jpost', 'administrator', 'wp-jpost', '', '', 100);
		add_submenu_page('wp-jpost', __('Add New','wp-jpost'), __('Add New','wp-jpost'), 'administrator', 'post-new.php?post_type=wp-jpost', '' );
                // do something
	}

注册自定义文章

		register_post_type(
			$slug,
			array(
				'labels'              => $labels,
				'public'              => true,
				'exclude_from_search' => apply_filters( 'jposts_exclude_from_search', true ),
				'show_ui'             => true,
				'query_var'           => true,
				'menu_position'       => 999,
				'supports'            => $supports_array,
				'rewrite'             => array(
					'slug'       => $rewrite_slug,
					'with_front' => false,
				),
				'show_in_menu'	=>	'wp-jpost',
				'show_in_rest'        => true,
			)
		);

注意参数 show_in_menu 。这里设置显示的位置。

JPostSettings 类中创建设置菜单

    public function __construct(){
        add_action( 'admin_menu', array( $this, 'settings' ) );
    }

添加子菜单

    // Add Menu 
    public function settings(){
        add_submenu_page('wp-jpost', __('Settings','wp-jpost'), __('Settings','wp-jpost'), 'administrator', 'wp-jpost', array($this, 'create_admin_page'));
    }

    /**
     * Options page callback
     */
    public function create_admin_page(){
        // Set class property
        $this->options = get_option( '_jpost_setting' );
        settings_errors();//show settings messages.
        printf( '<div class="wrap"><h1>%s</h1><form method="post" action="options.php">',__('WP-JPost Settings','wp-jpost') );
        settings_fields( '_jpost_option_group' );
        do_settings_sections( '_jpost_settings' );
        submit_button();
        printf( '</form></div>' );
    }

到这里我们的菜单就建立完成了。
