In WordPress, a filter is a program that may be attached to an event (called hooks). Whenever the event is activated during execution, the filter is implemented to the data output produced by the event hook. It’s vital to understand that WordPress filters operate on the information they collect and then provide that data to the browser before it’s shown.
Actions vs. Filters
To guarantee that data is output in the browser, filters must constantly have data coming in and out. The data can be passed through different filters before receiving output in the browser. Actions are identical to filters because they don’t require everything to be provided.
One of the two kinds of hooks is the filter.
They give functions a means to change data while WordPress Core, extensions, and themes are running. They are the antithesis of Actions.
Filters, unlike Actions, are designed to act in isolation and should not have adverse effects that influence global variables or output. Filters anticipate receiving something in return.
