Roku Developer Program

[djp]

Hello guys,

I have a PHP background, but I am totally new to RoKu/BrightScript development, although I seem to do be doing pretty well for having a pretty well polished app so far from just scouring and figuring things out so far, I was hoping it didnt have to come to this, but I must ask for help I have exhausted all of my searching on this so far.

I have used the videoplayer application as a starting point, I have managed to get a link page working and the search screen appended to the category xml that the videoplayer uses as a main screen.

Here is what I cannot for the life of me get working. I would like the search results from the roSearchScreen to post to a xml page http://example.com/roku/search.php?search=STRING so i can create a category xml file on the fly and take it to a poster view with the results.

I tried duplicating the showHomeScreen() function to no success.

Anyone who can help me with this, I will be greatly indebted to you and would love to help you out with anything

You could do something like this to get the content list Xml from the search screen. Once you have that, write whatever code you need to display them on a poster screen:

Sub Main()
    displaySearchUI ()
End Sub

Function displaySearchUI () As Void
    port = CreateObject ("roMessagePort")
    searchHistory = CreateObject ("roSearchHistory")
    searchHistoryList = searchHistory.GetAsArray ()
    ui = CreateObject ("roSearchScreen")
    ui.SetMessagePort (port)
    ui.SetSearchTermHeaderText ("Enter Search Terms")
    ui.SetSearchTerms (searchHistoryList)
    ui.SetSearchButtonText ("Search")
    ui.SetClearButtonEnabled (True)
    ui.Show ()
    While True
        msg = Wait (0, port)
        If Type (msg) = "roSearchScreenEvent"
            If msg.IsPartialResult ()                   ' Event fired for every character entered
                result = msg.GetMessage ()              ' Partial string - all characters entered so far
                partialSearchList = CreateObject ("roArray", searchHistoryList.Count (), False)
                For Each item In searchHistoryList
                    If Len (item) >= Len (result) And Left (item, Len (result)) = result
                        partialSearchList.Push (item)
                    EndIf
                End For
                ui.SetSearchTerms (partialSearchList)   ' Display search history items that match partial search chars
            Else If msg.IsFullResult ()
                searchTerm = msg.GetMessage ()
                searchHistory.Push (searchTerm)
                displaySearchResults (searchTerm)
            Else If msg.IsCleared ()
                searchHistory.Clear ()
            Else If msg.IsScreenClosed ()
                Exit While
            EndIf
        EndIf
    End While
End Function

Function displaySearchResults (searchTerm As String) As Void
    contentList = CreateObject ("roXmlElement")
    ut = CreateObject ("roUrlTransfer")
    url = "http://example.com/roku/search.php?search=" + ut.Escape (searchTerm)
    ut.SetUrl (url)
    data = ut.GetToString ()
    If data = ""
        Print "No data returned from: "; url
    Else
        If Not contentList.Parse (data)
            Print "Unable to parse Xml data:"
            Print data
        Else
            displayPosterUI (contentList)
        EndIf
    EndIf
End Function

Function displayPosterUI (contentList)
    Print "Displaying poster screen"
End Function

thank you, I have implemented your code and seems to be debugging correctly, how could i pass the contentlist to the xml parser thats already provided with the videoplayer sample to create a posterview??

It depends on what the Xml is that you get from your search query. If it's a <Category> element then you may be able to call ParseCategoryNode() to get a top-level node that you can pass to showPosterScreen(). The exact details, I'll leave to you to figure out. You'll probably have to spend some time actually figuring out how the example code works so you can change it to do what you want, which is the whole point of the SDK "examples"; they're more of a learning tool than a template.

Thank you sir, I was actually able to get this to work!
