need help! dvdasian.com script (picture only)

[Vagnard]

hi,
i tried myself on writing a picture import script.
thats the code so far, please could someone with more experience help me.
as i'm not really into programming there will be many errors in it, and it doesn't work yet.
so please could someone teach me how to get this one to work.

Code: Select all

program DVDasian;

// search pc-id

Function pcID:string;
var
 HomePageText:string;
begin
HomePageText := GetPage('http://www.dvdasian.com/');
pcID := TextBetween(HomePageText, 'ACTION="http://www.dvdasian.com/cgi-bin/dvdasian/search.html?', '">');
end;

// movie search

Procedure SearchMovie(Name:string; id:string);
var
 ResultsPage:string;
begin
PostPage('http://www.dvdasian.com/cgi-bin/dvdasian/search.html?' + 'id', URLEncode(Name));
Sleep(1000);
ResultsPage := GetPage('http://www.dvdasian.com/cgi-bin/dvdasian/search.html?' + 'pcID');

if Pos('No item is found for', ResultsPage) > 0 then
 begin
  ShowMessage('No movie found for this search');
 end
else
 begin
  PickTreeClear;
  until not AddMovieTitles(ResultsPage);
  if PickTreeExec(Address) then
   GetPicture(Address);
 end;
end;

// getting pictureaddress

function AddMovieTitles(List: string): Boolean;
var
 Value: string;
 Address: string;
 name: string;
begin
  Value := TextBetween(List, '<TD width="90" VALIGN="top">', 'BORDER="0"></A><BR>');
  List := RemainingText;
  while Value <> '' do
  begin
    name := TextBetween(Value, 'ALT="', '"');
    Address := TextBetween(Value, '<IMG SRC="', '.1.jpg"');
    PickTreeAdd(name, 'http://dvdasian.com' + Address + '.3.jpg');
    Value := TextBetween(List, '<TD width="90" VALIGN="top">', 'BORDER="0"></A><BR>');
    List := RemainingText;
  end;
 AddMovieTitles := True;
end;

// program

var
 MovieName:string;
 
begin
MovieName := '';
MovieName := GetField(fieldTranslatedTitle);
 if MovieName = '' then
 MovieName := GetField(fieldOriginalTitle);
 Input('DVDasian.com Import', 'Enter the title of the movie:', MovieName) Exit;
end
if MovieName <> '' then
begin
SearchMovie(MovieName, pcID);
end

thanks for any help,

Hi,

Yes, there are some bugs in your script but not much, keep try.

You used "PCId" for serach but there's actualy no need this. Instead i use

Code: Select all

AnalyzePage('http://www.dvdasian.com/cgi-bin/dvdasian/search.html?mv_searchspec='+UrlEncode(MovieName));

code for the same purpose.

I made some changes and wrote a small script for this site.

Code: Select all
