Uploading images to server using ASIHTTPRequest in iphone - ios4

Question

I have to upload images to server form iphone I am using ASIHTTPRequest for this. I have set a loop for uploading seven files. But after the executing only last file is uploaded can some one point out where I am getting it wrong.
I am using the below code for uploading :
for (int i=1; i<8; i++)
{
NSString* filename = [NSString stringWithFormat:#"Photo%d.jpg", i];
NSString *path = [[NSHomeDirectory() stringByAppendingPathComponent:#"Documents"] stringByAppendingPathComponent:filename];
[request setFile:path forKey:[NSString stringWithFormat:#"file"]];
}
[request startAsynchronous];
[resultView setText:#"Uploading data..."];
My Php file code is as following :
<?php
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
if (file_exists("vinay/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"vinay/" . $_FILES["file"]["name"]);
echo "Stored in: " . "http://serverpath" . $_FILES["file"]["name"];
}
}
?>

Answer 1

You're overwriting the key called file & you need to use a queue.
Do
[self setNetworkQueue:[ASINetworkQueue queue]];
[[self networkQueue] setDelegate:self];
for (int i=1; i<8; i++)
{
NSString* filename = [NSString stringWithFormat:#"Photo%d.jpg", i];
NSString *path = [[NSHomeDirectory() stringByAppendingPathComponent:#"Documents"] stringByAppendingPathComponent:filename];
[request setFile:path forKey:[NSString stringWithFormat:#"file%d", i]];
[[self networkQueue] addOperation:request];
}
[[self networkQueue] go];

You're overwriting request.file, hence only the last one gets uploaded. You have to make individual requests for each file.
Or you could use [request addFile:(id)data withFileName:(NSString *)fileName andContentType:(NSString *)contentType forKey:(NSString *)key] to send multiple files in one request.
