Tell us what you are trying to do?
Create a custom plugin to enable a button shortcode (or function) that when used to a page (or page button) that will create a PDF with the data from some views with the use of the FPDF (hidden link) which will be downloaded by the user.
Is there any documentation that you are following?
https://toolset.com/documentation/programmer-reference/views-api/#render_view
hidden link
Right now I have created the code for creating a simple PDF form but when I call the "render_view()" I get the error
<?php
