推荐答案
使用此代码上传图片和textLabel
Use this code to upload image and textLabel
NSData *imageData = UIImageJPEGRepresentation("yourImage",0.2); //change Image to NSData
if (imageData != nil)
{
filenames = [NSString stringWithFormat:@"TextLabel"]; //set name here
NSLog(@"%@", filenames);
NSString *urlString = @"http://xxxxxxx/yyyyy.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:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[filenames dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\"; filename=\".jpg\"\r\n"] 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]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(returnString);
NSLog(@"finish");
}
在php端使用此代码
$myparam = $_POST['userfile']; //getting image Here
$mytextLabel= $_POST['filenames'] //getting textLabe Here
echo $myparam;
echo $mytextLabel;
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['myfile']['name']);
if(move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['myfile']['name']) . " has been uploaded";
} else {
echo "There was an error uploading the file, please try again!";
}
