I'm not exactly sure if this is a VB.NET question, a PHP question, or both.
I have the following PHP web API that uploads a file to the server and then creates a record in the database that references the file location:
As you can tell, there is a lot going on to just upload a file.
Now I need to do the same thing, the only difference is that I want to do this from my VB.NET desktop application instead of my HTML/JQuery web application.
I feel like I could make a REST request, but I'm not sure how to include the file in the request because my PHP code expects the $_FILES.
On the other hand, I feel like it would be easier to write the files directly to my server and hit the database from my VB.NET application, but I'm not sure I can write files directly to my server.
What do y'all suggest?
