Question

Slowly but surely I think I’m going mad. After getting the solution to my problem and the app now also accepting spaces, it still won’t add the data that contains spaces to my mysql database. Here is the code:

NSString *strURL = [NSString stringWithFormat:@"http://www.bbc.com/phpFile.php?number=%@&name=%@&lastname=%@", number, firstName, lastName];
NSString *webStringURl = [strURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];
NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];

NSLog(@"%@", strResult);
NSLog(@"%@", webStringURl);

NSLog even tells me that it does exactly what I tell him to:

ProjectX[4003:15203] http://www.bbc.com/phpFile.php?number=11166&name=Yong%20Wang%20Ding&lastname=Blamblam

It works everytime when the variables do not contain spaces. When I open the php file in my browser and enter the variables by hand (with spaces) it adds them to my database. I have no clue why it refuses to work when doing exactly(?) the same thing with my app.

It doesn’t look like you’re using webStringURl (sic) anywhere other than in the final NSLog statement. Are you sure you didn’t mean to write:

NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:webStringURl];

…for the third line?

At the moment, you’re calling dataWithContentsOfURL on your unescaped version of the URL (which may still contain spaces).
