在WordPress中激活插件时调用我的函数的问题

时间：2019-06-26 作者：Faisal Janjua

我正在创建新的Wordpress插件，并将代码拆分为不同的文件以进行代码管理。这是我的主插件文件的代码my-best-plugin.php代码如下：

<?php
    if ( ! defined(\'ABSPATH\') ){
        die;
    }

    if(!defined(\'MY_PLUGIN_PATH\')) { 
        define( \'MY_PLUGIN_PATH\', plugin_dir_path(__FILE__) ); 
    }

    if( ! class_exists(\'MyBestPlugin\') ){
        class MyBestPlugin {

            function mbp_activate(){
                require_once MY_PLUGIN_PATH .\'inc/mbp-plugin-activate.php\';
                MBPActivate::activate();
            }

        }

        $pluginInstance = new MyBestPlugin();

        // activation
        register_activation_hook( __FILE__ , array( $pluginInstance, \'mbp_activate\' ) );

    }

现在，我的第二个激活文件位于inc/mbp-plugin-activate.php 代码如下：

<?php

    class MBPActivate {

        public static function activate(){
            // I want to do more here by calling functions
            // cpt(); 
            // dont know how to call function cpt()
            // also not sure is it running properly or not :P
            add_action(\'init\', array( \'MBPActivate\',\'cpt\' ));
            flush_rewrite_rules();
        }

        public static function cpt(){
            register_post_type(\'book\', [\'public\'=>true, \'label\'=>\'Books\']);
        }

    }

首先，我不确定我的插件激活文件是否正在运行，但没有给出错误，而且当我调用自己的函数时，它会给出致命错误或已发送的标题错误。请告诉我如何在激活插件文件的激活过程中调用我的函数。提前感谢：）

我会这样做：-

   // Make sure we don\'t expose any info if called directly
if ( ! defined(\'ABSPATH\') ){
    die;
}

if(!defined(\'MY_PLUGIN_PATH\')) { 
    define( \'MY_PLUGIN_PATH\', plugin_dir_path(__FILE__) ); 
}

if( ! class_exists(\'MyBestPlugin\') ){
        class MyBestPlugin {

            public function __construct(){
                register_activation_hook( __FILE__ , array( $this, \'mbp_activate\' ) );
                register_deactivation_hook( __FILE__ , array( $this, \'mbp_deactivate\' ) );
                if(get_option(\'cpt_enable\')){
                   add_action( \'init\', array($this, \'cpt\' ) ); 
                } //get the \'cpt enabled option if available.Hit the hook\'
            }

            public function mbp_activate(){
                require_once MY_PLUGIN_PATH .\'inc/yes.php\';
                MBPActivate::activate();
            }

            public function mbp_deactivate(){
                require_once MY_PLUGIN_PATH .\'inc/yes.php\';
                MBPActivate::deactivate();
            }

            public function cpt(){
                $args = array(
                                \'public\'    => true,
                                \'label\'     => __( \'Books\', \'textdomain\' ),
                                \'menu_icon\' => \'dashicons-book\',
                            );
                register_post_type( \'book\', $args );
            }

        }

        $pluginInstance = new MyBestPlugin();

}

/////下一页是。php////

class MBPActivate {
        public function activate(){
            add_option(\'cpt_enable\',\'cpt_enable\'); // set the cpt enabled option after activation hook.
            flush_rewrite_rules();
        }
        public function deactivate(){
            delete_option(\'cpt_enable\');
            flush_rewrite_rules();
        }
    }
    $plugin = new MBPActivate();

请尝试以下代码

my-plugin.php file

<?php
/**
Plugin Name: My Plugin
Plugin URI: http://#####
Description: This plugin just for test

if ( ! defined(\'ABSPATH\') ){
        die;
}
if(!defined(\'MY_PLUGIN_PATH\')) { 
    define( \'MY_PLUGIN_PATH\', plugin_dir_path(__FILE__) ); 
}

function mbp_activate(){
  flush_rewrite_rules();
  add_option( \'my_plugin_activated\', time() );
}
require_once MY_PLUGIN_PATH .\'inc/mbp-plugin-activate.php\';
function run_mbpactive() {

    $plugin = new MBPActivate();

}
run_mbpactive();

register_activation_hook( __FILE__ , \'mbp_activate\'  );


register_uninstall_hook( __FILE__, \'my_plugin_uninstall\' );
function my_plugin_uninstall() {
     unregister_post_type( \'book\' );
     delete_option("my_plugin_activated");
}

        register_post_type( \'book\', $books_args );

    }
