Introduction: In this tutorial, we’ll explore how to extend the functionality of the WordPress REST API by creating a custom endpoint that allows you to retrieve posts in CSV format. This can be particularly useful when you need to export a specific set of posts with selected fields for data analysis or other purposes.

Code Overview:

Code Explanation:

We use the rest_api_init action hook to register our custom REST route, making it accessible at /wp-json/get-all-post/v1/post/.

The change_post_to_csv_function function handles the logic for retrieving posts based on parameters and generating a CSV file.

Generating CSV File:

The code uses the fputcsv function to format and write the post data into a CSV file in memory.
Column headers and row data are added to the CSV file using the fetched post information.

Downloading the CSV File:

Finally, the code sets the necessary headers to prompt the browser to download the generated CSV file.

Conclusion: By following this tutorial, you can enhance your WordPress site with a custom REST API endpoint tailored to your needs, providing a convenient way to export posts in CSV format.
