How to make an insert request?

Question

PHP

I can't query the database at all. In general, to the point. There is a form It is
necessary to build a query so that it adds both fields with name="cat" to the table.
I did this, but the error...

INSERT INTO video_category(video_id, category_id) VALUES(:video_id, :cat, :cat)

Here is what the table looks like

Answer 1

So you insert 3 into 2 fields.
Rename the second input name to cat2.

INSERT INTO video_category(video_id, category_id) VALUES(:video_id, :cat)
INSERT INTO video_category(video_id, category_id) VALUES(:video_id, :cat2)
