wp_unslash

wp_unslash is a WordPress function that is used to remove slashes from a string or an array of strings. This is often necessary because WordPress automatically adds slashes to data received from user input (like form submissions) to escape special characters. The wp_unslash function reverses this process, making the data usable.

Here’s the basic syntax for wp_unslash:

wp_unslash( $value );

• $value: (mixed) The data to be unslashed. It can be a string or an array of strings.

Why use wp_unslash?

When working with form data or any user input in WordPress, it’s crucial to sanitize and validate the input to prevent security vulnerabilities. The wp_unslash function is part of this process, ensuring that slashes added by WordPress are removed before further processing the input data.
