I have been working on an XCode project and I need some server-side code to go along with the Objective C. All I am trying to do is upload an image to the server.
I am currently using XAMPP to use my PHP file, and the image I am trying to upload should be going to localhost folder 'hopeImages'. However, upon running the PHP in my Chrome browser, I receive several messages reading:
Notice: Undefined index: userfile in...
Here is the Objective C, 'img' is defined elsewhere; I receive no errors in this code.
- (void)heyMethod
{
NSData *imageData = UIImagePNGRepresentation(img);
NSString *urlString = @"http://localhost/hopeImages/upload.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:[[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:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\".png\"\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]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
}
Sorry for all the unused code, I have been trying several solutions, none of which have worked of course...
Here is the PHP file, upload.php
<?php
$uploaddir = './'; //Uploading to same directory as PHP file
$file = basename($_FILES['userfile']['name']);
$uploadFile = $file;
$randomNumber = rand(0, 99999);
$newName = $uploadDir . $randomNumber . $uploadFile;
if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
echo "Temp file uploaded. \r\n";
} else {
echo "Temp file not uploaded. \r\n";
}
if ($_FILES['userfile']['size']> 300000) {
exit("Your file is too large.");
}
?>
As for HTML, I have no idea where I would put it. Do I even use HTML in this situation? Do I run the PHP before the XCode application? Any answers are greatly appreciated.
