HTTP Post Upload Multiple Files from iOS to PHP -


in ios app, i'm building nsdata use body nsmutableurlrequest can upload multiple files in 1 http post.

the contents of post body (with file data removed , replaced byte count):

multipart/form-data; charset=utf-8; boundary=0xkhtmlboundary --0xkhtmlboundary content-disposition: form-data; name="email" myemailaddress@gmail.com --0xkhtmlboundary content-disposition: form-data; name="sqlite"; filename="backup.myapp.v1.1.3-to-v1.1.3.1443578420.sqlite" content-type: application/octet-stream  // ... data length: 880640  --0xkhtmlboundary-- content-disposition: form-data; name="sqliteshm"; filename="backup.myapp.v1.1.3-to-v1.1.3.1443578420.sqlite-shm" content-type: application/octet-stream  // ... data length: 32768  --0xkhtmlboundary-- content-disposition: form-data; name="sqlitewal"; filename="backup.myapp.v1.1.3-to-v1.1.3.1443578420.sqlite-wal" content-type: application/octet-stream  // ... data length: 3901672  --0xkhtmlboundary--

however, on php side when receive post, i'm seeing first of 3 files. if put 1 named "sqlite" first, on php side, see "sqlite" file. if put 1 named "sqliteshm" first, see "sqliteshm" file in $_files array.

array ( 'sqliteshm' =>      array (       'name' => 'backup.myapp.v1.1.3-to-v1.1.3.1443578420.sqlite-shm',       'type' => 'application/octet-stream',       'tmp_name' => '/private/var/tmp/phpk1wywb',       'error' => 0,       'size' => 32768,     ), )

the file size matches up, regardless of 1 put first, first file ever shows on php side.

do need special in order receive multiple files on php side?

or sending multiple files incorrect ios?

in short, request not valid.

in more detail, notice difference between --0xkhtmlboundary-- , --0xkhtmlboundary. separator uses 2 dashes @ end -- terminator. result, request body isn't parsed beyond first terminator, happens right after first file. there should 1 terminator - @ end of request.

generally, shouldn't reinvent wheel when comes composing multipart form data requests. use proven , time tested library afnetworking.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
