Hi dear WordPress tooltip users, hope this message find you are doing well and have happy days with your family:) We just released Smart Content Links with Tooltip plugin 2.0, in this version, we added an API : “scl_content” filter for Smart Content Links with Tooltip plugin.

what wordpress filter?

A WordPress filter is a function that allows developers to modify the behavior of WordPress core functions, themes, and plugins. Filters are used to modify the output of WordPress functions or to add new functionality to WordPress. Filters are applied to data before it is displayed on the website or stored in the database. They are used to modify the content, title, meta tags, and other elements of a WordPress site. Some examples of WordPress filters include the_content, the_title, wp_title, and wp_head. Developers can create their own custom filters to modify WordPress functionality to suit their needs.

For example, wordpress tooltip plugin and smart content link plugin using the wordpress  `the_content` filter, it is a WordPress filter that allows developers to modify the content of a post or page before it is displayed on the front-end of a website. This filter is applied to the post content when it is retrieved from the database and before it is displayed on the website. Developers can use this filter to add or remove content, modify the formatting of the content, or even add custom functionality to the content. The `the_content` filter is commonly used in WordPress themes and plugins to customize the way content is displayed on a website.

This makes smart content link plugin more flexible and customizable, as users can make changes without having to worry about their modifications being overwritten when the plugin is updated.
