The images I try to upload from my Iphone gallery are all saved as ipodfile.jpg
I want the exact image name which I am selecting from the gallery and I want to create a folder (with the login username) and I want to store inside the folder
For example
Then I want to create a folder named mike
and save the image inside.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
[self dismissModalViewControllerAnimated:true];
img = [info valueForKey:UIImagePickerControllerOriginalImage];
//images.image = img;
NSData *imageData = UIImageJPEGRepresentation(img, 90);
NSString *urlString = @"http://192.168.1.92/Abdul/IOS/Chat/upload_file.php";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = @"---------------------------14737809831466499882746641449"
;
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Disposition: form-data; name=\"file\"; filename=\"ipodfile.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"Successfully uploaded");
}
This is the server-side code I'm using
<?php
$oname=$_FILES["file"]["name"];
$tempname=$_FILES["file"]["tmp_name"];
$path="upload";
echo "Upload: " . $oname . "<br />";
echo "Temp file: " . $tempname . "<br />";
echo "<br>";
$ex=file_exists("upload/$oname");
if($ex)
{
echo "File Already exist";
}
else
{
$upload=move_uploaded_file($tempname,$path.$oname);
if($upload)
{
echo "Sucessfully Stored in: " . $path. $oname;
}
else
{
echo "Not stored Sucessfully : " . $path.$oname;
}
}
You should take unique file name for every image like timestamp which will always be unique.
in below line you are setting image name so set it with time stamp.
[body appendData:[@"Content-Disposition: form-data; name=\"file\"; filename=\"ipodfile.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
You can kepp unique name aomething like this which i have used once,
NSDate *currentDate = [[NSDate alloc] init];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
NSString *localDateString = [dateFormatter stringFromDate:currentDate];
NSString* cleanedString = [[localDateString stringByReplacingOccurrencesOfString:@"." withString:@""]stringByReplacingOccurrencesOfString:@":" withString:@""];
NSString *cleanedString2 = [cleanedString stringByAppendingFormat:@"%d",i];
NSString *finalUniqueImageNAme = [cleanedString2 stringByAppendingString:@".jpg"];
Hope this will help ;)
Update :
you can use unique name like this,
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"%@\"\r\n",finalUniqueImageNAme] dataUsingEncoding:NSUTF8StringEncoding]];
And second thing you should use AFNetworking
to do this kind of stuff. it'll manage all this kind of stuff like set boundary etc. Click here for AFNetworking github
Update 2 (according to query of comment):
You should use NSURLSession
instead of nsurlconnection
because connection is deprecated now so your code should be like this
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (data) {
//if response is in string format
NSString *str = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
//if response in json format then
id jsonObject = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
}
}]resume];
changes the path to
$path="mike/";
and then upload image. By this way your image will be uploaded in mike folder.
NSData *imageData = UIImagePNGRepresentation(yourImage);
NSString *urlString = [ NSString stringWithFormat:@"http://192.168.1.92/Abdul/IOS/Chat/upload_file.php"];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[[body appendData:[@"Content-Disposition: form-data; name=\"file\"; filename=\"%@\"\r\n",img] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
