upload images and texts to server [closed]

I have already gone through some codings, and I found some interrupts in uploading.

I want to upload six images to a server folder and some text to server database using ASIHTTPRequest. Any sample code please, thanks for spending time for my question.

For uploading images to the server you need the following code:

NSURL *url = [NSURL URLWithString:@"http://www.xyz.com/UploadImage.php"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
request.requestMethod = @"POST";
NSString *fileName = @"iphone.jpg";
[request addPostValue:fileName forKey:@"name"];

// Upload an image
UIImage *img = [UIImage imageNamed:fileName];
NSData *imageData = UIImageJPEGRepresentation(img, 90);
[request setData:imageData withFileName:fileName andContentType:@"image/jpeg" forKey:@"image"];
[request setDelegate:self]; 
[request startAsynchronous];

For sending text to the server, you just need to append the text with the POST method like:

[request appendPostData:[@"This is my data" dataUsingEncoding:NSUTF8StringEncoding]];

Cheers!!!

Here is the code for image uploading, you can use it

-(void)uploadImage

{
    UIImage *image = [UIImage imageWithName:@"sample.jpeg"]; 
    NSData *imageData = UIImageJPEGRepresentation(image, 90);
    NSURL *url = [NSURL URLWithString:@"http://your-url/upload.php"];
    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    [request setDelegate:self];
    [request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];



[request startAsynchronous];

}

- (void)requestFinished:(ASIHTTPRequest *)request
{
    // Use when fetching text data
    NSString *responseString = [request responseString];
    NSLog(@"response: %@", responseString);

    // Use when fetching binary data
    NSData *responseData = [request responseData];
}

- (void)requestFailed:(ASIHTTPRequest *)request
{
    NSError *error = [request error];
}

For text, you can use this

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request appendPostData:[@"This is my data" dataUsingEncoding:NSUTF8StringEncoding]];
// Default becomes POST when you use appendPostData: / appendPostDataFromFile: / setPostBody:
[request setRequestMethod:@"PUT"];
