You can now access the page count for a PDF upload in your calculations by using this tag:
The first step is to enable the feature by going to WooCommerce > Settings > Product Add-Ons > Uploads. Enable these settings and click ‘Save changes’.
- Enable PDF uploads
- Enable PDF page count
Then, create the following fields.
An Upload field which now accepts a PDF file. You will need to disable ‘Allow multiple uploads’ as the calculation will only read 1 file.
Create a Calculation field that will reference the Upload field. When a PDF file is uploaded, the calculation will retrieve the number of pages.
