  2. Activate the plugin through the ‘Plugins’ menu in WordPress Admin
  3. Inspect and Save your settings with the dashboard menu item ‘STC Subscribe > Settings’.
  4. Create a page and add shortcode [stc-subscribe] or use the STC Widget to display STC form subscription.
  5. Inspect /create / update subscribers with the dashboard menu item STC Subscriber > Subscribers

Shortcode Attributes

‘category_in’ – 如果你想让一个或者多个分类能够被订阅，使用这个属性。输入值是分类名称。注意只有顶级分类（无父级）才能够被输入。
‘category_id_in’ – 与上面不同的就是用ID代替了分类名称。
‘category_not_in’ – 使用这个属性排除订阅分类。输入值是分类名称。
‘category_id_not_in’ – 与上面不同的就是用ID代替了分类名称。
上面的属性你可以使用逗号来分隔多个分类, 如 [stc-subscribe category_in=”news, article”]。

‘hide_unsubscribe’ – hide_unsubscribe=”true” 禁止取消订阅功能，只在相应的短代码属性在管理设置中也被激活时起效。
‘treeview_folded’ – treeview_folded=”false” 默认是否开启分类、标签的层级视图。
‘treeview_enabled’ – treeview_enabled=”false” 取消分类、标签的层级视图。请注意只有被选中的分类或标签才会起效。
‘keyword_search’ – keyword_search=”on” 在选中的文章类型中开启关键词搜索功能，. 默认是关闭的。
‘subscriber_notification’ – subscriber_notification=”true” 开启基于用户的订阅通知功能。 默认是关闭的。
‘mobile_phone’ – mobile_phone=”on” 开启短信通知功能。短信通知就想邮件一样，将针对新文章或更新文章进行通知推送。

Filter and hooks

Following filters and hooks can be used for customizing the email message.

<?php
// FILTERS
// Parameters: $value
add_filter( 'stc_message_length_sum_of_words', 'stc_message_length_sum_of_words', 10, 1 ); //set return value to a negative number to show the full content


// Parameters: $value, $post_id, $subscriber_post_id
add_filter( 'stc_message_title_html', 'my_stc_message_title_html', 10, 3 );
add_filter( 'stc_message_link_to_post_html', 'my_stc_message_link_to_post_html', 10, 3 );
add_filter( 'stc_message_unsubscribe_html', 'my_stc_message_unsubscribe_html', 10, 3 );

add_action( 'stc_before_message', 'my_stc_before_message', 10, 2 );
add_action( 'stc_before_message_title', 'my_stc_before_message_title', 10, 2 );
add_action( 'stc_after_message_title', 'my_stc_after_message_title', 10, 2 );
add_action( 'stc_before_message_content', 'my_stc_before_message_content', 10, 2 );

add_action( 'stc_after_update_subscriber', 'my_stc_after_update_subscriber', 10, 3 );
add_action( 'stc_after_insert_subscriber', 'my_stc_after_insert_subscriber', 10, 3 );

// Parameters: $subscriber_post_id, 
add_action( 'stc_before_unsubscribe', 'my_stc_before_unsubscribe', 10, 1 ); // runs before deleting a subscriber from database
add_action( 'stc_before_subscribe', 'my_stc_before_subscribe', 10, 1 ); // runs before adding a subscriber to the database


/**
 * Example for adding featured image to STC email
 */
function my_stc_after_message_title( $post_id ){
    echo get_the_post_thumbnail( $post_id, 'thumbnail' );
}
add_action( 'stc_after_message_title', 'my_stc_after_message_title', 10, 2 );

?>

Optionally but recommended

As WordPress Cron is depending on that you have visits on your website you should set up a Cron job on your server to hit http://yourdomain.com/wp-cron.php at a regular interval to make sure that WP Cron is running as expected. In current version of Subscribe to Category the WP Cron is running once every hour, that might be an option that is changeable in future versions.
Therefore, a suggested interval for your server Cron could be once every 5 minutes.

常见问题

让STC插入额外的HTML内容到通知邮件里

是的，在通知邮件中通过使用可行的hooks置入HTML，这需要一些编程技巧。在2.4.9版本后，同时样式将有有更多的可能性。你可以在screenshot-10.jpg中看到在哪里你可以置入代码。

要重新开始的最好方法就是把所有的HTML邮件模板删除（已发布的与已删除的）。之后STC订阅将自动设置一个可编辑的模板文件，如screenshot-11中一样。别忘了在STC订阅-> 设置中，选中这个模板。

或者根据下面三个步骤：
步骤1：STC订阅->通知->添加新的通知来创建通知模板。
步骤2：编辑模板文章（做好在单一的html编辑模块下完成），所有的样式代码必须在每一个html模块内。要注意不是每个邮件服务商都支持HTML样式的。请使用插件专用占位符{{post_title}}，{{post_content}}，{{justify}} 和 {{unsubscribe}}。
步骤3：在STC订阅->设置中，激活相应的的通知模板。

STC小工具能够控制属性吗？

是的，从2.4.16版本起，小工具设置中就添加了属性区域。格式与短码中使用的相同。

STC能够兼容自定义文章类型吗

是的，从2.4.1版本开始，用户可以将自定义文章分类和STC进行捆绑，你可以在STC设置页面选择“自定义文章类型”。

Can STC handle custom Taxonomies

Yes, from version 2.3.1 it is possible to link STC with Custom created Taxonomies. You can activate these within STC on the STC admin settings page.

为什么我只有0层级的分类在过滤器中

这是因为你选择了一个子分类作为过滤器，树状图无法在分类结构的中间开始展示。但是，当属性 ‘treeview_enabled=”false”‘ 被激活时，你可以选择一个没有父级的子分类，他们将会显示成单个的分类项。

我如何能够启动普通清单模式而不是树状图模式

你可以通过设置短代码 attribute treeview_enabled=”false” 设置分类形式为清单模式。请注意，当次属性被激活后，在过滤器里的分类层级将被忽略，结果将和过滤器属性的清单模式一样。

导入订阅者名单的文件格式是什么？

STC 只能处理表单文件，因为分类信息都会被逗号隔开的。
Excel文件能支持你导出txt文件的表单。

Great plug-in

2022年8月29日
This is exactly what I was looking for in order to be able to send personalized publications to subscribers which other plugins do not do and simple to configure. Not to mention responsive support Thanks to the Developers

Exactly what I was looking for

2022年6月15日 1 回复
I wanted to allow readers to subscribe to what they were interested in and this was the plugin I needed. It's simple and straightforward and works. The maintainer is also very helpful and responsive. The one feature I'm waiting for is to be able to have the author's name in the email.

widget does not work

2022年4月23日 1 回复
This has wasted me a lot of time. The widget does not work. It does appear on the sidebar, but attributes simply do not work. I tried many variations and read the instructions, and was very sure I did the way as instructed. But no, it does not work. Something does happen based on the attributes entered, but completely unpredictable and unreliable.

Just what I needed

2021年7月13日
No nonsense plugin without unnecessary marketing features. Simple and with good documentation, if you bother to read through it carefully (which I didn't but that's on me). Active and helpful developer with great support. Even got in a call with me to help, far beyond anything you can demand. Getting a placeholder for the updated category without "Term:" and "found." would be great but that's too small an issue to complain about.

A little treasure

2021年5月6日
This plugin does exactly what it should and it comes with amazing support. Some other review says: "Do one thing and do it well" I totally agree.
