As a WordPress plugin developer, you may want to offer content restriction as part of your plugin’s functionality. Content restriction can take many forms, but it typically boils down to one thing: preventing access to content unless certain conditions are met. In this article, we’ll discuss how to implement content restriction in a WordPress plugin.
Why Restrict Content?
There are many reasons why you might want to restrict content in your WordPress plugin. For example, you might want to:
- Prevent access to certain features unless a user is logged in
- Restrict access to certain content types (e.g. posts, pages, etc.)
- Limit access to certain areas of the plugin interface
- Offer content “teasers” to lure users into taking a specific action (e.g. subscribing to a newsletter)
How to Restrict Content
Now that we’ve discussed some of the reasons why you might want to restrict content in your WordPress plugin, let’s take a look at how to actually do it. There are two primary ways to restrict content in WordPress:
- Using the WordPress API – This is the preferred method, as it makes use of existing WordPress functionality and is therefore more “future proof”.
- Using custom code – This method is more flexible, but it also requires more custom code and is therefore more likely to break in future WordPress releases.
Restricting Content Using the WordPress API
The WordPress API provides a number of functions that can be used to restrict content. The most commonly used functions are is_user_logged_in() and current_user_can(). These functions can be used together to restrict content based on a user’s role or capabilities.
is_user_logged_in()
is_user_logged_in() is a boolean function that returns true if a user is logged in, and false if a user is not logged in. This function can be used to restrict content to logged in users only.
current_user_can()
current_user_can() is a capability check function. It takes a capability as an argument and returns true if the current user has the specified capability. This function can be used to restrict content based on a user’s capabilities.
Restricting Content Using Custom Code
If you need more flexibility than what the WordPress API offers, you can always write your own custom code to restrict content. The most common way to do this is by using PHP conditions.
For example, let’s say you want to restrict content to logged in users only. You could do this by using the following code:
if ( !is_user_logged_in() ) {
// content here will only be displayed to logged in users
}
Or, let’s say you want to restrict content to users with the “edit_posts” capability. You could do this by using the following code:
if ( !current_user_can( 'edit_posts' ) ) {
// content here will only be displayed to users with the "edit_posts" capability
}
As you can see, custom code can be used to achieve pretty much any type of content restriction. The downside of this approach is that it requires more custom code, and is therefore more likely to break in future WordPress releases.
Summary
In this article, we’ve discussed how to implement content restriction in a WordPress plugin. We’ve looked at the reasons why you might want to restrict content, and we’ve examined two different ways to do it.
If you need to restrict content in your WordPress plugin, we recommend using the WordPress API. This is the preferred method, as it makes use of existing WordPress functionality and is therefore more “future proof”.
With the release of WordPress 4.7, a new feature called Content Restriction was introduced. This feature allows you to restrict access to certain pieces of content on your WordPress site. For example, you could restrict a post to only be accessible to logged-in users, or only to users who have purchased a certain product.
In this article, we’ll show you how to implement content restriction in WordPress plugin.
First, you need to install and activate the Content Restriction plugin. For more details, see our step by step guide on how to install a WordPress plugin.
Once the plugin is activated, you need to visit Settings » Content Restriction page to configure the plugin settings.
On the settings page, you need to select the post types that you want to restrict. By default, the plugin restricts access to posts and pages. If you want to restrict access to other post types, then you need to select them from the dropdown.
Next, you need to select the user roles that you want to restrict. By default, the plugin restricts access to all user roles except administrators.
If you want to restrict access to specific posts or pages, then you need to scroll down to the “Individual Posts/Pages” section and select the posts or pages that you want to restrict.
Once you are done, click on the “Save Changes” button to store your settings.
Now that you have configured the plugin settings, it’s time to test it out.
To test it, you need to visit a post or page that you have restricted. You will be redirected to the login page.
Once you login, you will be able to access the restricted post or page.
That’s it! You have successfully implemented content restriction in WordPress plugin.
