激活插件时创建wordpress模板

Question

当激活插件时，我想要创建一个新的模板，其中包含一个简短的代码。我用的是插件样板发生器。我试过使用这个https://github.com/tommcfarlin/page-template-example/，但是它没有工作。我还尝试使用

function add_my_custom_page() {
    // Create post object
    $my_post = array(
      'post_title'    => wp_strip_all_tags( 'My Custom Page' ),
      'post_content'  => '[shortcode]',
      'post_status'   => 'publish',
      'post_author'   => 1,
      'post_type'     => 'page',
      'page_template'  => 'templates/template-full-width.php'
    );

    // Insert the post into the database
    wp_insert_post( $my_post );
}

register_activation_hook(__FILE__, 'add_my_custom_page');

但由此生成的页面存在样式问题。不是全宽的。

Answer 1

public function quote_shortcode() {
        if ( ! is_admin() ) {
            ob_start();
            include(__DIR__.'/../template/create-quote.php');
            return ob_get_clean();
        }

    }

这是因为某种原因-在创建短代码时添加了这段代码。

根据您的主题，页面模板在默认情况下可能是使用侧栏设置的。

您可以通过在wp_insert_post函数中指定页面模板来解决这个问题。

function add_my_custom_page() {
    // Create post object
    $my_post = array(
      'post_title'    => wp_strip_all_tags( 'My Custom Page' ),
      'post_content'  => 'My custom page content',
      'post_status'   => 'publish',
      'post_author'   => 1,
      'post_type'     => 'page',
      // Assign page template
      'page_template'  => 'template-full-width.php'
    );

    // Insert the post into the database
    wp_insert_post( $my_post );
}

register_activation_hook(__FILE__, 'add_my_custom_page');

当然，您需要检查主题文件以找到/创建与template-full-width.php等效的文件，并在必要时替换上面代码中的名称。

我已经为同样的插件创建了自定义插件，下面是步骤

步骤1:转到插件目录，为自定义插件创建一个名为template-maker

• step-2:的新文件夹，现在创建插件的主文件template-maker.php，并粘贴到下面的代码中。

<?php
/*
Plugin Name: Template Maker
Version: 0.0.1
Author: Addweb Solution

*/

class PageTemplater {

  /**
   * A reference to an instance of this class.
   */
  private static $instance;

  /**
   * The array of templates that this plugin tracks.
   */
  protected $templates;

  /**
   * Returns an instance of this class. 
   */
  public static function get_instance() {

    if ( null == self::$instance ) {
      self::$instance = new PageTemplater();
    } 

    return self::$instance;

  } 

  /**
   * Initializes the plugin by setting filters and administration functions.
   */
  private function __construct() {

    $this->templates = array();


    // Add a filter to the attributes metabox to inject template into the cache.
    if ( version_compare( floatval( get_bloginfo( 'version' ) ), '4.7', '<' ) ) {

      // 4.6 and older
      add_filter(
        'page_attributes_dropdown_pages_args',
        array( $this, 'register_project_templates' )
      );

    } else {

      // Add a filter to the wp 4.7 version attributes metabox
      add_filter(
        'theme_page_templates', array( $this, 'add_new_template' )
      );

    }

    // Add a filter to the save post to inject out template into the page cache
    add_filter(
      'wp_insert_post_data', 
      array( $this, 'register_project_templates' ) 
    );


    // Add a filter to the template include to determine if the page has our 
    // template assigned and return it's path
    add_filter(
      'template_include', 
      array( $this, 'view_project_template') 
    );


    // Add your templates to this array.
    $this->templates = array(
      'goodtobebad-template.php' => 'Plugin-template',
    );

  } 

  /**
   * Adds our template to the page dropdown for v4.7+
   *
   */
  public function add_new_template( $posts_templates ) {
    $posts_templates = array_merge( $posts_templates, $this->templates );
    return $posts_templates;
  }

  /**
   * Adds our template to the pages cache in order to trick WordPress
   * into thinking the template file exists where it doens't really exist.
   */
  public function register_project_templates( $atts ) {

    // Create the key used for the themes cache
    $cache_key = 'page_templates-' . md5( get_theme_root() . '/' . get_stylesheet() );

    // Retrieve the cache list. 
    // If it doesn't exist, or it's empty prepare an array
    $templates = wp_get_theme()->get_page_templates();
    if ( empty( $templates ) ) {
      $templates = array();
    } 

    // New cache, therefore remove the old one
    wp_cache_delete( $cache_key , 'themes');

    // Now add our template to the list of templates by merging our templates
    // with the existing templates array from the cache.
    $templates = array_merge( $templates, $this->templates );

    // Add the modified cache to allow WordPress to pick it up for listing
    // available templates
    wp_cache_add( $cache_key, $templates, 'themes', 1800 );

    return $atts;

  } 

  /**
   * Checks if the template is assigned to the page
   */
  public function view_project_template( $template ) {

    // Get global post
    global $post;

    // Return template if post is empty
    if ( ! $post ) {
      return $template;
    }

    // Return default template if we don't have a custom one defined
    if ( ! isset( $this->templates[get_post_meta( 
      $post->ID, '_wp_page_template', true 
    )] ) ) {
      return $template;
    } 

    $file = plugin_dir_path( __FILE__ ). get_post_meta( 
      $post->ID, '_wp_page_template', true
    );

    // Just to be safe, we check if the file exist first
    if ( file_exists( $file ) ) {
      return $file;
    } else {
      echo $file;
    }

    // Return template
    return $template;

  }

} 
add_action( 'plugins_loaded', array( 'PageTemplater', 'get_instance' ) );

• 步骤3:现在打开wp-admin面板插件选项卡，您将在其中找到模板制造者插件，激活它
• 步骤-4:从管理仪表板创建新页面-> page ->Add，并选择

。

备注：您可以根据使用

设置文件夹名和文件名
