Online functionality is one of the bigger weaknesses of Construct.
Of course the Download object does its job fine for downloading, but I'm afraid there is no object that is able to directly upload files.
With the HTTP Object you can communicate with websites, such as passing arguments through a PHP script/HTML form. I've used it before to create a simple flatfile highscore table.
I haven't used the object in quite a while, but together with a proper PHP upload script, it should be able to get the job of uploading a file done.
[quote="Noga":96bux2j8]In actions there is:
1. Add file - what argument name means? (same with add number and string)
2. Set user agent - what is it and usage?
3. Requests - what is it and usage?[/quote:96bux2j8]
1. See above - adding arguments when you post to a site basically. Like it could pass the username, a password and a message, all being different arguments.
2. User agent would be the string which is used to identify your browser, to be able to choose the appropriate content to display for example.
3. 'Get' and 'Post' would obviously refer to the HTTP methods of the same names. Take a look here
maybe. With 'Get' you could also download any site as a string, which would be returned in the expression 'HTTP.GetResponse'. And with 'Post', well, you usually post stuff.
Keep in mind that I'm no authority on these online matters though, I hope I was able to provide some insight at least. Anyone able to add to that or correct me by all means do post!
