This post will give you an overview of what WordPress plugins are, how they work, and some of the most popular examples.
What is a WordPress plugin?
A WordPress plugin is a piece of software that “plugs into” your WordPress site. Plugins can add new functionality or extend existing functionality on your site, allowing you to create virtually any kind of website, from ecommerce stores to portfolios to directory sites.
Plugins can make small tweaks on your site or massive changes, depending on their features. For example, you could use a plugin toadd a WhatsApp share button到您的网站或create a fully multilingual site。或者，如果您经营电子商务业务，则可以将插件安装到assist with payment gateways或允许游客在线预约。
有also plugins that can help youenhance your contact forms，，，，制作美丽的滑块，，，，backup your site如果数据失败，并使电子邮件选择加入简单 - 加上很多more.
While many make changes to the front end of your site, some plugins make changes on the back end so maintenance is easier for your team. These plugins might allow you to扫描您的网站是否有链接，，，，run A/B tests， 或者put your site into maintenance mode， 例如。
现在，我们可以更好地了解什么插件，让我们仔细研究它们的工作方式。
How do WordPress plugins work?
Plugins allow you to add or extend the functionality of your WordPress site without changing core WordPress files. Plugins use access points, formally known as filter and action hooks, provided by the WordPress Plugin API to “hook into” the source code. These access points and methods will call the functions of the plugin at specific times and modify the default behavior of WordPress.
A plugin developer who wants to use theWordPress Plugin APIto create a plugin will start by creating a PHP function to, say, delete comments with profanity from their site. Then they’ll hook the function to a specific event, such as saving comments to the WordPress database or publishing a post, by using theadd_filter() functionoradd_action（）函数。
Let’s say this developer wants to create a plugin that adds a line of text that says “Thank you for reading!” below every post on a WordPress site. In that case, the function of the plugin would be adding “Thank you for reading!” to a post and the event that triggers the function would be publishing a post. So their plugin file would look something like the following:
<？php
/**
* Plugin Name: Thank You Plugin
* Plugin URI: http://www.mywebsite.com/thank-you-plugin
* Description: The very first plugin that I have ever created.
* Version: 1.0
* Author: Your Name
* Author URI: http://www.mywebsite.com
*/
add_action( 'the_content', 'my_thank_you_text' );
功能my_thank_you_text（$ content）{
return $content .= 'Thank you for reading!
';
？>
现在假设你是一个网站所有者想要添加this functionality to your site. In that case, you'd need to add the plugin to your WordPress website. Let's look at the different ways you can do so below.
如何在WordPress中使用插件
有多种方法可以添加WordPress插件到您的网站。例如，您可以从仪表板，官方的WordPress插件目录或第三方站点进行此操作。可以单击一次自动安装官方目录的插件，而某些高级插件必须通过A手动安装文件传输协议（FTP）客户端。
To install a plugin from the official WordPress directory, you simply have to log into your dashboard and selectPlugins>Add New。这n search for the plugin using the built-in search bar. From there, you just have to click安装and启用。
To understand how to install a plugin that's not available in the official directory, let's return to the plugin example above. If the "Thank you for reading!" plugin is not available in the directory, then you would download the plugin as a zip file and save it in theWP-CONTENT/插件folder of your directory via an FTP client. This would automatically install the plugin to your WordPress site.
然后您会导航到Plugins在你管理仪表板。一旦你找到了newly uploaded plugin from the list of installed plugins on your site, you’d just click the plugin’s “Activate” link and be all set! From then on, every time you published a post, the line “Thanks for reading!” would be automatically added to the bottom of the post.
Most plugins begin working right away, but you may need to configure their settings to ensure they're working the way you want them to. For example, if you were using theWP Staging – DB & File Duplicator & Migrationplugin toset up a WordPress staging site，然后您需要转到插件的设置页面，然后单击创建新的舞台网站。然后，输入一些信息，例如登台站点的名称以及您想复制的内容。否则，插件将不会自动上台。
If this sounds like a lot of work, then you might be wondering why people use plugins instead of editing core WordPress files to add functionality to their site. That’s because, when updating to a new version of WordPress, all the core files — and any edits made to them — are overwritten. To add that same functionality on your updated site, you’d have to go back in and edit the core files again.
但是，如果您安装插件以在网站中添加功能，那么您只需要担心keeping the plugins updated。
现在，我们了解了什么插件，它们的工作方式以及如何使用它们，让我们看一些可以在WordPress站点中添加基本功能的插件。
