In the Chronoforms7 admin area, go to the Extend page.
Choose the tcpdf library file you have downloaded from the ChronoForms7 downloads page.
Open your form and make sure it's of type "Advanced" then "Save" to reload the form editor, or create a new form and select "Advanced form"
Open to the Pages area in your form.
Click Actions to enable Actions editing and insertion.
Click Advanced in the Actions bar.
Find the TCPDF Export action in the list.
Drag a TCPDF Export action to the "end_page" Actions area.
Open the TCPDF action settings.
You can change the PDF file name or path, the full path matters only if you are going to "store" the file on your web server.
Choose what to do with the resulting file, Download or Store or Display immediately ? Please note that Download and Display Inline will block any further actions processing, so if you choose any of them then make sure you have no more actions after the TCPDF action.
Edit the PDF file contents, you can use the {data:field_name} shortcode to call any form field file.
