-
Hello,
I want to ad an option to send on subcripter only some post so i found this
https://jetpack.me/support/subscriptions/they say to add this code
php
add_filter( ‘jetpack_allow_per_post_subscriptions’, ‘__return_true’ );in function.php but always I get the white dead screen , My theme is twenty eleven and my function.php is the code that you can see.
Can someone help me to make it exactly? because when I add this line
php
add_filter( ‘jetpack_allow_per_post_subscriptions’, ‘__return_true’ );I probably do something wrong but what?
thank you in advance<?php /** * Twenty Eleven functions and definitions * * Sets up the theme and provides some helper functions. Some helper functions * are used in the theme as custom template tags. Others are attached to action and * filter hooks in WordPress to change core functionality. * * The first function, twentyeleven_setup(), sets up the theme by registering support * for various features in WordPress, such as post thumbnails, navigation menus, and the like. * * When using a child theme (see https://codex.ww.wp.xz.cn/Theme_Development and * https://codex.ww.wp.xz.cn/Child_Themes), you can override certain functions * (those wrapped in a function_exists() call) by defining them first in your child theme's * functions.php file. The child theme's functions.php file is included before the parent * theme's file, so the child theme functions would be used. * * Functions that are not pluggable (not wrapped in function_exists()) are instead attached * to a filter or action hook. The hook can be removed by using remove_action() or * remove_filter() and you can attach your own function to the hook. * * We can remove the parent theme's hook only after it is attached, which means we need to * wait until setting up the child theme: * * <code> * add_action( 'after_setup_theme', 'my_child_theme_setup' ); * function my_child_theme_setup() { * // We are providing our own filter for excerpt_length (or using the unfiltered value) * remove_filter( 'excerpt_length', 'twentyeleven_excerpt_length' ); * ... * } * </code> * * For more information on hooks, actions, and filters, see https://codex.ww.wp.xz.cn/Plugin_API. * * @package WordPress * @subpackage Twenty_Eleven * @since Twenty Eleven 1.0 */ // Set the content width based on the theme's design and stylesheet. if ( ! isset( $content_width ) ) $content_width = 584; /* * Tell WordPress to run twentyeleven_setup() when the 'after_setup_theme' hook is run. */ add_action( 'after_setup_theme', 'twentyeleven_setup' ); if ( ! function_exists( 'twentyeleven_setup' ) ): /** * Set up theme defaults and registers support for various WordPress features. * * Note that this function is hooked into the after_setup_theme hook, which runs * before the init hook.
