Question

我有一个应用程序，我可以将数据发布到数据库并检索它，我发布了一个坐标数组，我从用户位置的移动中收集了这些坐标，例如

"37.351701,-122.105898",
"37.351945,-122.106109",
"37.352183,-122.106338",
"37.352409,-122.106568"

如果数组有大约180行，则不会将其发布到数据库，或者如果我跟踪从中收集坐标超过3分钟的用户也不会添加。我无法理解为什么会这样，我可以手动添加300行坐标，我可以从NSLog中取出数据库并检索它，但不是通过php从xcode发布它。

我如何创建坐标数组

if ((oldLocation.coordinate.latitude != newLocation.coordinate.latitude) &&
        (oldLocation.coordinate.longitude != newLocation.coordinate.longitude))

    self.trackCoord = [NSString stringWithFormat:@"%f,%f",newLocation.coordinate.latitude, newLocation.coordinate.longitude];

        if (!self.trackArray) {
        self.trackArray = [[NSMutableArray alloc] init];
    }
    [self.trackArray addObject:self.trackCoord];

我用它来发布数组

-(void) shareRoute:(NSString*) to withName:(NSString *) from withName:(NSString *) name withName:(NSString *) type withName:(NSString *) duration withName:(NSMutableArray *) trackArrayList{

if (from != nil && to != nil && name != nil){

    NSMutableString *postString = [NSMutableString stringWithString:shareURL];

    [postString appendString:[NSString stringWithFormat:@"?%@=%@", Sfrom, from]];
    [postString appendString:[NSString stringWithFormat:@"&%@=%@", Sto, to]];
    [postString appendString:[NSString stringWithFormat:@"&%@=%@", Sname, name]];
    [postString appendString:[NSString stringWithFormat:@"&%@=%@", Stype, type]];
    [postString appendString:[NSString stringWithFormat:@"&%@=%@", Sduration, duration]];
    [postString appendString:[NSString stringWithFormat:@"&%@=%@", StrackArray, trackArrayList]];

    [postString setString:[postString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:postString]];
    [request setHTTPMethod:@"POST"];

    postConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];        
}

}

和这个

- (IBAction)shareButton:(id)sender{

    [self shareRoute:toLabel.text withName:fromLabel.text withName:routeNameTextField.text withName:typeLabel.text withName:durationLabel.text withName:trackArray];
    [toLabel resignFirstResponder];
    toLabel.text = nil;
    fromLabel.text = nil;
    routeNameTextField.text = nil;
    typeLabel.text = nil;
    durationLabel.text = nil;
    trackArray = nil;
    [[NSNotificationCenter defaultCenter] postNotificationName:@"Test1" object:self];

}

}

php code

$name = $_GET["name"];
$from = $_GET["from"];
$to = $_GET["to"];
$type = $_GET["type"];
$duration = $_GET["duration"];
$trackArray = $_GET["trackArray"];


$query = "INSERT INTO routes VALUES ('', '".mysql_real_escape_string($name)."', '".mysql_real_escape_string($from)."', '".mysql_real_escape_string($to)."', '$type', '$duration', '$trackArray')";

在数据库中，我尝试使用TEXT的{{1}}和MEDIUMTEXT值。 MySQL表。

trackArray

所有其他数据都已成功发布，我还发布了其他数组，其中包含多行和数据，但过多的数据显示使用以上作为示例。

为什么没有添加多行数组的任何想法？

通过php将数据坐标发布到数据库
