I'm making a 'post text' app and trying to update my database with name and body field. The obj-c code looks like this:

- (IBAction)post:(id)sender

{

    NSLog(@"%@", name);

    NSLog(@"%@", body);

    // create string contains url address for php file, the file name is post.php, it receives parameter :name

    NSString *strURL = [NSString stringWithFormat:@"http://www.mywebsite.com/post.php?name=%@&body=%@",name, body];

    // to execute php code

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

    // to receive the returend value

    NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];

    NSLog(@"%@", strResult);

}

And the php code looks like this:

<?php

if (isset($_REQUEST['name']) && isset($_REQUEST['body']) && strlen($_REQUEST['name']) > 0 && strlen($_REQUEST['body']) > 0) {

    //get data

    $title = $_REQUEST['name'];

    $body = $_REQUEST['body'];

    mysql_connect("MyServer","username","password") or die(mysql_error());

    mysql_select_db("Database_Name") or die(mysql_error());

    $date = date("Y-m-d");

    //insert data

    $insert = mysql_query("INSERT INTO news VALUES ('','".mysql_real_escape_string($title)."','".mysql_real_escape_string($body)."','".mysql_real_escape_string($date)."')") or die(mysql_error());

    die("Your text has been posted!");

}

?>

Sometimes it works to post through the app but then it just post (null) as name and null as body. But for the most part it doesn't work at all. It just says in the log:

    2012-06-26 16:54:49.893 AppName[12444:707]

<UITextField: 0x17a390; frame = (63 76; 194 31); text = 'MyName';

clipsToBounds = YES; opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x17a4c0>>

Taking a wild guess here but are name and body pointers to a UITextField object? I'm thinking they might be, based on your log output. If so, you need to use [name text] or name.text to get the actual NSString value from the text field.
