在插件激活(Wordpress)上添加html/PHP页面


Add html/PHP pages on plugin activation (Wordpress)

我正在创建我的第一个wordpress插件,它应该在激活时创建一个页面(相对较大)。

目前我可以创建一个文件:

$_p['post_title'] = $the_page_title;
        $_p['post_content'] = '<h1>PAGE CONTENT</h1>';
        $_p['post_status'] = 'publish';
        $_p['post_type'] = 'page';
        $_p['comment_status'] = 'closed';
        $_p['ping_status'] = 'closed';
        $_p['post_category'] = array(1); // the default 'Uncatrgorised'
        // Insert the post into the database
        $the_page_id = wp_insert_post( $_p );

问题是,我不能把文件的所有内容(这是大)作为字符串'post_content'索引。我想知道是否有一种方法,我可以简单地:

  1. 'post_content' =>链接到我的插件目录
  2. 'post_content' =>调用一个返回html内容字符串的函数:([最坏的情况]
  3. 或者,一些更简单的方法来实现目标。

请帮帮我。

我解决这个问题的方法是:

//**SECTION : 1** 
   function user_login_foo() {
    return get_login_form(); // get_login_form() function will return the html template i want to display.
}
add_shortcode('user_login', 'user_login_foo'); // created a shortcode

**// SECTION: 2**
function get_login_form()
    {
        ob_start(); ?>
        <h3><?php __('Login'); ?></h3> 
        <form action="" method="post">
            <fieldset>
                 // the login form comes here
            </fieldset>
        </form>
    <?php
    return ob_get_clean();
    }
    function validate_login_user() {
             // the login validation logic comes here
    }
    add_action('init', 'validate_login_user');

SECTION 1:注册了一个短代码,它将调用函数[例如,foo1()]并返回值。函数foo1()调用另一个函数[例如foo2()],该函数返回一个干净的html表单以响应调用(当调用短代码时)。

第2节:在本节中,我定义了函数foo2(),其中定义了html表单[login form]并返回给foo1()[显示它的地方]。然后我创建了一个动作[add_action('init', 'validate_login_user');在初始化时调用函数validate_login_user(),在这个函数中,我检查了isset(METHOD[username])和isset(METHOD[password]),然后执行相应的逻辑。

就像这样,我为每个我想在激活时创建的页面创建了多个[短代码],然后:

 **step 1:** register_activation_hook(__FILE__,'activation_plugin'); 
 **step 2:** activation_plugin(){
     '390' => [ // '390' is page id
           'post_title' => 'Page title say login',
           'post_content' => "[user_login]",
           'post_status' => 'publish',
           'post_type' => 'page',
           'comment_status' => 'closed',
           'ping_status' => 'closed',
           'post_category' => array(1)
        ],
        '391' => [
           'post_title' => 'page title 2',
           'post_content' => "[short_code2]",
           'post_status' => 'publish',
           'post_type' => 'page',
           'comment_status' => 'closed',
           'ping_status' => 'closed',
           'post_category' => array(1)
        ],
         // like this add multiple shortcodes 
   }
      // this foreach will create all the pages
      foreach ($_ as $key => $value) {
        $the_page_title = $value['post_title'];
        $the_page_name = $value['post_title'];
        // the menu entry...
        delete_option($value['post_title']);
        add_option($value['post_title'], $the_page_title, '', 'yes');
        // the slug...
        delete_option($value['post_title']);
        add_option($value['post_title'], $the_page_name, '', 'yes');
        // the id...
        delete_option($key);
        add_option($key, '0', '', 'yes');
        $the_page = get_page_by_title( $the_page_title );
        if ( ! $the_page ) {
            $the_page_id = wp_insert_post( $value );
        }
        else {
            $the_page_id = $the_page->ID;
            $the_page->post_status = 'publish';
            $the_page_id = wp_update_post( $the_page );
        }
        delete_option( $key );
        add_option( $key, $the_page_id );
    }

创建关于插件激活的页面

$page_content= 'Content of page';
$demo_page = array(
      'comment_status' => 'closed',
      'ping_status' =>  'closed' ,
      'post_author' => 1,
      'post_content' => $page_content,
      'post_date' => date('Y-m-d H:i:s'),
      'post_name' => 'page_name',//display on address bar
      'post_status' => 'publish' ,
      'post_title' => 'Page Display Name',
      'post_type' => 'page',
);  
//insert page and save the id
$demo_page_value = wp_insert_post( $demo_page, false );
//save the id in the database
update_option( 'testpage', $$demo_page_value );
