Post preview as PDF?

Question

WordPress

There are cards that are generated from posts on wp and there is a photo that can be added in the admin panel. And there is a button by clicking on which opens the PDF, the customer wants a preview of the PDF file that is added below instead of the photo. Well, as a preview, as I understand it, just the file is just the size of the photo. What would the photo look like. How is this implemented?

Answer 1

if the task is like "when displaying a bunch of posts, I want to click on one and go directly to pdf"
then the solution is
- with acf
make a field in which you either select a pdf or just a link to the pdf and in the records archive (where all posts are displayed as previews) do a link in which the href contains the path to pdf, and the content is a regular preview (the same photo that needs to be added to the entry)
- without acf,
insert the link to pdf in the usual content field (only you need to remove the wrapper from there. this is done if you select tab " text")
then make a link in which the href is the_content() and the content is a regular preview (the same photo that needs to be added to the post)
