Why Use WordPress Plugins? 

WordPress plugins offer a wide range of benefits, including flexibility, ease of use, cost-effectiveness, community support, security, and many more. By leveraging the power of plugins, users can enhance their websites and create a more engaging and effective online presence.

The benefits of using WordPress plugins include:

  • Extends Functionality: Plugins let you add features that aren’t included in the base WordPress software. This could be anything from contact forms and e-commerce capabilities to social media sharing buttons and SEO optimization tools.
  • Enhances User Experience: With plugins, you can create a more user-friendly and engaging website for your visitors. For instance, you can add image galleries, create sliders, or implement live chat functionalities to improve user interaction.
  • Improves Security: Security is paramount. Plugins can help strengthen your website’s defenses against malware and cyberattacks. They can offer features like user login security, spam filtering, and vulnerability scanning.

  • Time-Saving: Plugins can provide ready-to-use functionalities, eliminating the need to build everything from scratch. For example, developers can easily integrate features like contact forms, image sliders, and shopping carts into their websites or applications within minutes.

How do WordPress Plugins Work?

WordPress plugins use hooks and filters to connect with the WordPress platform’s core functions. These are also the core elements of WordPress plugin development. 

Hooks let plugins perform specific tasks at certain times during the website’s loading process, while filters tweak data before it appears on the site, allowing for customization.

Plugins are typically made up of PHP files and other assets like JavaScript and CSS. When someone visits your WordPress site, the WordPress core and active plugins load together. If a plugin’s function is needed, WordPress calls its code to do the job.

Plugins can affect different parts of your site, from what visitors see to the admin area and database. They can add new features, change existing ones, or work with outside services to make your site better.

Imagine a contact form plugin. Here’s how it might work:

  • The plugin registers an action hook to be executed when a user submits the contact form.
  • Upon form submission, WordPress triggers the action hook.
  • The plugin’s code captures the submitted data (name, email, message).
  • The plugin might use a filter to format the data before sending it as an email.
  • Finally, the plugin leverages WordPress’s built-in email functionality to send the contact form information to your designated email address.

Where to Find WordPress Plugins?

WordPress plugins can be found in the official WordPress Plugin Directory within the WordPress dashboard, as well as through external sources for both free and premium plugins. The Official WordPress Plugin Directory is highly recommended for its safety and reliability. 

To find a plugin simply log in to your WordPress admin dashboard. Then head to Plugins > Add New, and use the search bar or browse through categories and featured plugins. That’s it!

Alternatively, you can explore reputable third-party marketplaces like CodeCanyon, Elegant Themes, and ThemeForest. These platforms offer premium WordPress plugins (come at a cost) with extended features and functionalities beyond what’s available in the free directory. 

When obtaining plugins from external sources, users typically receive a .zip file containing the plugin, which can be uploaded and installed through the WordPress dashboard. 

How to Install Plugins in WordPress?

There are two main ways to install a WordPress plugin. Through the WordPress dashboard which is the easiest way or install it manually. 

Go to the admin area of your WordPress website and access the “Plugins” section. You can do this by typing your website address followed by “/wp-admin” (e.g., www.yourwebsite.com/wp-admin) into your web browser. 

Now find your desired plugin as we shown in the previous section. FNow, select the “Install Now” option next to the plugin you wish to add. WordPress will automatically download and install the plugin for you. 

Once installed, click on the “Activate” button to start using the plugin on your site.

For paid or premium plugins, the process is slightly different. 

First, purchase and download the plugin from the marketplace or plugin store usually in a zip format. Then, within the WordPress admin area, go to “Plugins” and select “Add New”. 

Choose the “Upload Plugin” option and upload the plugin file from your computer. Click on “Install Now” to upload and install the plugin, then activate it by clicking the “Activate Plugin” link just like before.

How to Update a Plugin in WordPress?

WordPress offers users the flexibility to update plugins either manually or automatically. To update a WordPress plugin, follow these methods:

Method 1: Updating Plugins from the WordPress Dashboard (Recommended)

This is the simplest and most recommended approach for updating plugins:

  • Log in to your WordPress admin dashboard and navigate to Plugins.
  • You’ll see a list of all installed plugins on your website.
  • If updates are available for any plugins, you’ll see a notification with an “Update Now” button next to the plugin name.
  • Click the “Update Now” button next to the specific plugin you want to update. WordPress will download and install the update automatically.
  • To update all at once, check the box next to “Plugin,” choose “Update” from the Bulk Actions menu, then click “Apply.”  Wait for the confirmation message after clicking “Update Now.” That’s it!

WordPress has an auto-update feature that updates plugins without the website owner’s manual input. You can turn off this feature for specific plugins in your WP Admin by clicking “Disable auto-updates” whenever you prefer.

Method 2: Updating Plugins Manually (For Advanced Users)

This method is less common and recommended for advanced users comfortable with manual file management. Here’s how it works:

  • Go to the official WordPress Plugin Directory or the developer’s website for premium plugins. Download the newest version of the plugin file, usually a .zip file.
  • In your WordPress dashboard, head to Plugins. Find the plugin to update and click “Deactivate”.
  • Using FTP or your web host’s file manager, find the wp-content/plugins directory on your server. Delete the old plugin folder completely.
  • Now, using FTP or the file manager, upload the new plugin .zip file to the wp-content/plugins directory.
  • Back in your WordPress dashboard, go to Plugins, find the newly uploaded plugin, and click “Activate”.

Note: Always remember to back up your site before updates, especially manual ones, to restore it if something goes wrong.

How to Remove or Deactivate Plugins in WordPress?

As time goes on, you might have lots of plugins installed on your website that you don’t use anymore. While they can be helpful, keeping unused plugins can slow down your website in the long term.

Deciding whether to deactivate or delete a WordPress plugin depends on whether you need it later. If you want to keep the plugin’s data, you can deactivate it instead of uninstalling it. Turning off a plugin stops it from working but keeps its information saved.

Some plugins might leave data in your database. If you’re comfortable with databases, you can manually delete it, but it’s usually safe to leave it unless you have database size issues.

Here’s a quick guide to both methods,

Deactivating a Plugin

Deactivating a Plugin disables its functionality without removing its files. This is ideal if you’re unsure about using the plugin later or want to temporarily disable it for troubleshooting.

To deactivate a plugin, log in to your WordPress dashboard and navigate to the “Plugins” section. Locate the plugin you wish to deactivate and click on “Deactivate” next to its name.

Finally, confirm the deactivation if prompted, typically through a popup window. Some plugins may ask for feedback on why you want to deactivate the plugin and it is common.

Removing/Deleting a Plugin

If you’re sure you don’t need a plugin anymore, you can remove it completely. This deletes all its files and features from your website. Remember, you’ll have to reinstall it if you change your mind later.

To do so, deactivate the plugin first (if active). Then, in the Inactive section, you’ll see a “Delete” link right below the plugin name. Click “Delete” to permanently delete the plugin.

How to Choose the Right WordPress Plugin

Choosing the right WordPress plugin is a must for your website’s success. All that is required is a proper balance between the plugin functionality, user experience, and your needs. 

Follow these steps to make the right choice:

  • List the core functionalities your website requires. For instance, if you run an online store, you’ll need inventory management, shopping carts, payment gateways, and customer review plugins.
  • Look for plugins on https://wordpress.org/plugins and check their last updated date. If it’s more than 4 months ago, it might indicate the plugin is not regularly maintained. Regular updates often include security enhancements. Remember to keep your plugins updated to stay protected against vulnerabilities.
  • Opt for plugins that have received high ratings and positive feedback, as this indicates their quality and reliability.
  • Opt for plugins with robust support options like forums, email, or real-time chat. Especially for premium plugins, prompt and helpful support is crucial.
  • While free WordPress plugins can be great, premium options often provide additional features and better support. If budget isn’t an issue think about investing in a premium plugin.
  • Ensure the plugin offers extensive documentation and tutorials to understand its advanced features thoroughly.
