Noob needs help with search

Every time I try to search for something nothing happens.
No suggestions load and I don't get any results..
I can't seem to figure this out for the life of me..

I just used the sdk examples and tweaked them as needed
Here's the source code

Function SearchScreen()
InitTheme()

print "start"
'toggle the search suggestions vs. search history behavior
'this allow you to generate both versions of the example below
displayHistory = false
history = CreateObject("roArray", 1, true)
'prepopulate the search history with sample results
'history.Push("the old paths")
'history.Push("good news of the kingdom")

port = CreateObject("roMessagePort")
screen = CreateObject("roSearchScreen")
'commenting out SetBreadcrumbText() hides breadcrumb on screen
screen.SetBreadcrumbText("", "search")
screen.SetMessagePort(port)

if displayHistory = true
screen.SetSearchTermHeaderText("Recent Searches:")
screen.SetSearchButtonText("search")
screen.SetClearButtonText("clear history")
screen.SetClearButtonEnabled(true) 'defaults to true
screen.SetSearchTermHeaderText("Suggestions:")
else
screen.SetSearchTermHeaderText("Suggestions:")
screen.SetSearchButtonText("search")
screen.SetClearButtonEnabled(false)
endif

print "Doing show screen..."
screen.Show()
print "Waiting for a message from the screen..."

' search screen main event loop
done = false
while done = false
msg = wait(0, screen.GetMessagePort())
if type(msg) = "roSearchScreenEvent"
if msg.isScreenClosed()
print "screen closed"
done = true
screen.close()
else if msg.isCleared()
print "search terms cleared"
history.Clear()
else if msg.isPartialResult()
print "partial search: "; msg.GetMessage()
if not displayHistory
screen.SetSearchTerms(GenerateSearchSuggestions(msg.GetMessage()))
endif
else if msg.isFullResult()
print "full search: "; msg.GetMessage()
history.Push(msg.GetMessage())
if displayHistory
screen.AddSearchTerm(msg.GetMessage())
end if
Print "Delta"
searchResults(msg.GetMessage())

'uncomment to exit the screen after a full search result:
done = true
screen.close()
else
print "Unknown event: "; msg.GetType(); " msg: ";msg.GetMessage()
endif
endif
endwhile
print "Exiting..."
End Function


Function GenerateSearchSuggestions(partSearchText As String) As Object

suggestions = CreateObject("roArray", 1, true)

url = "http://www.map2life.com/roku/php/search.php?"
partsearch = url + partSearchText

Print"Searchconn()"
alpha = searchconn(partsearch)

If aplha <> "Can't parse feed" then
Print "alpha push"

for each e in alpha
suggestions.push(e.Title)
end for

Print "Alpha push completed"
else
Print "Error in search suggestion parse"
end if

return suggestions

End Function



Function searchResults(searchtext As String) As Void

search = url + searchtext

results = searchconn(search)

If results = "Can't parse feed" then
text = "I'm sorry, we Couldn't find any results for your request. Try rewording your request."
title = "Search Error"
ShowDialog1Button(title, text, "Done")
else
Print "Bravo 1"
screen = preShowDetailScreen("", "Search Results")
index = 0
showDetailScreen(screen, results, index)
end if

End Function



Function searchconn(searchUrl As String) As Dynamic


print searchUrl
http = NewHttp(searchUrl)

Re: Noob needs help with search

Have you actually debugged this in the debug console? There are two issues that I see, both with the "alpha" check in GenerateSearchSuggestions.


  1. You've misspelled "alpha" as "aplha" which will crash with a "Use ofun initialized variable." error.

  2. searchconn() returns either an array or a string, but you're checking to see if the value of alpha is (not) equal to a specific string ("Can't parse feed"). If searchconn() successfully returns a search results array, then this check will crash with a "Type mismatch." error.

If you change that line to the following, it should work:
if islist(alpha) then

You have a similar issue in your searchResults() function. You also have a typo in the StreamUrl node of your search XML. And, you really should URL encode the search text before appending it to the search URL.

Re: Noob needs help with search

No, I didn't debug..My friend loads them for me cause I don't have a Roku.
I didn't even think of a type mismatch error..It does make way more sense to test it with islist() though.
Thank you! I t works great now!
