NSString *urlStr=[NSString stringWithFormat:#"%#/InsertUserInfo?User_Name=%#&User_Pwd=%#&User_FName=%#&User_LName=%#&User_Mail=%#&User_Phno=%#&User_Address=%#&User_Dob=%#&Ic_No=%#&User_Active=%#&User_Questions=%#&User_Ans=%#",globalurl,usernameTxtFld.text,pwdTxtFld.text,firstName.text,lastName.text,email.text,phonNO.text,address.text,dateOfbirth.text,nricNo.text,#"10001",#"",#""];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:urlStr]];
[request setRequestMethod:#"POST"];
[request setDelegate:self];
[request addData:dataImage withFileName:#"Image.png" andContentType:#"image/png" forKey:#"photo"];
//check if passedData is nil
if (dataImage == nil)
{
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"title:iDnil" message:#"nil" delegate:nil cancelButtonTitle:#"fgff" otherButtonTitles:#"erer", nil];
[alert show];
}
[request startAsynchronous];
-(void)requestFinished:(ASIHTTPRequest *)request {
NSString *receivedString = [request responseString];
NSLog(#"received messge %#",receivedString);
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:#"Message" message:receivedString delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alertView show];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
dataImage = UIImageJPEGRepresentation([info objectForKey:#"UIImagePickerControllerOriginalImage"],1);
NSLog(#"dict is %#",info);
UIImage *image=[info objectForKey:UIImagePickerControllerOriginalImage];
[self dismissModalViewControllerAnimated:YES];
}

Answer 1

You can use
[request setFile:#"YOUR IMAGE FILE PATH" forKey:#"photo"];
instead of [request addData:dataImage withFileName:#"Image.png" andContentType:#"image/png" forKey:#"photo"];
as explained in the post . It worked for me like a charm :-)

I have uploaded an example application performing textfile, Image, Video, Images upload in queue, Videos to GitHub on this link. You may well consider having a look at it.
ASI-http-request has an optimisation option to stream your image files right away from your disk, which is the best I've seen with this library. Please consider using the below code snippet for creating ASIFormDataRequest.
// Initilize Variables
NSURL * url = [NSURL URLWithString:IMAGE_POST_URL];
// Add Image
NSString *path = [[NSBundle mainBundle]pathForResource:#"image1" ofType:#"jpg"];
// Get Image
NSData *imageData = [[NSData alloc]
initWithContentsOfFile:path];
// Return if there is no image
if(imageData != nil){
//Request-1
ASIFormDataRequest * request1;
[request1 setTag:201];
request1 = [[ASIFormDataRequest alloc] initWithURL:url];
[request1 setPostValue:#"ID = 201" forKey:#"image_upload"];
[request1 setFile:path forKey:#"image1_file"];
[request1 setDelegate:self];
[request1 setDidFinishSelector:#selector(imageUploadDidFinish:)];
[request1 setDidFailSelector:#selector(imageUploadDidFail:)];
[request1 setTimeOutSeconds:500];
[request1 setShouldStreamPostDataFromDisk:YES];
}
