I am maintaining some code that upload photos from an ipad onto apache2 server via objective-c and php. In objective-c the picture is updated using AFNetworking POST function. The picture actually is being uploaded successfully, however it is incomplete. Here is what I get on the server:
As you can see it only shows the top left part of the screenshot. The code in objective-c is something like these for imagePickerController
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
LoginData * dataObject = [self dataObject];
NSString *tempPath = [NSString stringWithFormat:@"upload-image.jpg"];
NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:tempPath];
UIImage *img = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *imageData = UIImageJPEGRepresentation(img, 1);
[imageData writeToFile:path atomically:YES];
NSString *uploaddir = [NSString stringWithFormat:@"../exampledir/"];
NSString *requestURL = [NSString stringWithFormat:@"http://%@/handle_upload.php", httpPath];
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:path, @"newname",uploaddir, @"pathname", nil];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:requestURL parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:@"uploadedfile" fileName:path mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
[[[UIAlertView alloc]
initWithTitle:@"Message" message:@"Upload was successful" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]show];
NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"%@", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error with upload : %@", error);
[[[UIAlertView alloc]
initWithTitle:@"Message" message:@"Upload was completed" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]show];
}];
[picker dismissViewControllerAnimated:YES completion:NULL];
}
and the file "handle_upload.php" is as followed:
<?php
require_once("validate.php");
/* This script uploads a file to a given directory with a given name
* Parameters:
* @pathname - the path of the directory the file will be uploaded to
* @newname - the new name of the file
* @uploadedfile - the file to be uploaded
*/
$target_path = $_POST['pathname'];
$new_name = $_POST['newname'];
$target_path = $target_path . basename($new_name);
if ($_FILES['uploadedfile']['error'] > 0) {
echo "There was an error transferring the file" . PHP_EOL;
echo "Error code: " . $_FILES['uploadedfile']['error'] . PHP_EOL;
}
if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file " . basename( $_FILES['uploadedfile']['name']) .
" has been uploaded"; // success is indicated by presence of string 'has been uploaded'
} else {
echo "There was an error uploading the file, please try again!" . PHP_EOL;
echo '$_POST[\'pathname\']: ' . $_POST['pathname'] . ' $_POST[\'newname\']: ' . $_POST['newname'] . PHP_EOL;
echo '$target_path: ' . $target_path . PHP_EOL;
echo "Upload: " . $_FILES["uploadedfile"]["name"] . PHP_EOL;
echo "Type: " . $_FILES["uploadedfile"]["type"] . PHP_EOL;
echo "Size: " . ($_FILES["uploadedfile"]["size"] / 1024) . PHP_EOL;
echo "Stored in: " . $_FILES["uploadedfile"]["tmp_name"] . PHP_EOL;
}
?>
Have anyone every meet this kind of problem before? I will be really appreciate to any help even just some direction to solve this problem.
