Getting 500 internal error using MKNetworking PHP image upload

I switched from the usual way to download images (if it didn’t work then) to use MKNetworking to help me with the download process, im using this method because I found that I get better answers about errors and helps solve my problems. I got NSLog answer with error reading

I can successfully upload images via the html form, so I'm sure my php.ini is ok and they are allowed to upload the path more than what I requested to upload to my iPhone.

and last but not least, my php

I solved my problem by switching to AFNetwork heres my new code

 - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { image.image = [info objectForKey:UIImagePickerControllerOriginalImage]; [self->image setImage:image.image]; [self dismissViewControllerAnimated:YES completion:NULL]; NSURL *url = [NSURL URLWithString:@"http://atmeapp.com"]; AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url]; NSData *imageData = UIImageJPEGRepresentation(image.image, 1); NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: @"email", [MyClass str], nil]; NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/addavatar.php" parameters:params constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) { [formData appendPartWithFileData:imageData name:@"userfile" fileName:[MyClass str] mimeType:@"image/jpeg"]; }]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) { NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite); }]; [httpClient enqueueHTTPRequestOperation:operation]; }

im not sure why this worked, but what ... very annoying. Thanks for all the time.

It looks mostly correct, I just downloaded MkNetworkKit / image in php. The only thing I see here is the line

 [NSMutableDictionary dictionaryWithObjectsAndKeys: @"email", [MyClass str]

You probably want to switch @ "email" and [MyClass str], when using the WithObjectsAndKeys dictionary, the values ​​should appear before the key.

Here is my implementation (inside a subclass of MKNetworkEngine):

 -(MKNetworkOperation*) uploadImage:(UIImage*)image onSuccess:(EmptyBlock)successBlock onError:(MKNKErrorBlock)errorBlock { NSMutableDictionary *params = [[NSDictionary dictionary]mutableCopy]; [params setValue:@"[YOUR_VALUE]" forKey:@"[YOUR_KEY]"]; MKNetworkOperation *op = [self operationWithPath:@"[YOUR_PATH]" params:params httpMethod:@"POST"]; [op addData:UIImageJPEGRepresentation(image, 0.5) forKey:@"userfile" mimeType:@"image/jpeg" fileName:@"[YOUR_FILENAME]"]; [op onCompletion:^(MKNetworkOperation *completedOperation) { if(successBlock) { successBlock(); } } onError:^(NSError *error) { TFLog(@"RCNetworkEngine.uploadError:%@, error:%@", url, [error localizedDescription]); if(errorBlock) errorBlock(error); }]; [self enqueueOperation:op]; return op; }
