i wondering if there setting on iphone or php script missing let me grab gps part of exif when try upload iphone. want grab gps array exif_read_data when upload pictures website through iphone.

an exif example safari on iphone:

image type is: jpeg  file.filename: 20130417141031image.jpg file.filedatetime: 1366225831 file.filesize: 1692449 file.filetype: 2 file.mimetype: image/jpeg file.sectionsfound: any_tag, ifd0, exif computed.html: width="3264" height="2448" computed.height: 2448 computed.width: 3264 computed.iscolor: 1 computed.byteordermotorola: 1 ifd0.orientation: 6 ifd0.exif_ifd_pointer: 38 exif.colorspace: 1 exif.exifimagewidth: 3264 exif.exifimagelength: 2448

an exif example of same image uploaded pc taken same phone:

image type is: jpeg  file.filename: 20130417142504image.jpeg file.filedatetime: 1366226835 file.filesize: 1744896 file.filetype: 2 file.mimetype: image/jpeg file.sectionsfound: any_tag, ifd0, thumbnail, exif, gps computed.html: width="3264" height="2448" computed.height: 2448 computed.width: 3264 computed.iscolor: 1 computed.byteordermotorola: 1 computed.aperturefnumber: f/2.4 computed.thumbnail.filetype: 2 computed.thumbnail.mimetype: image/jpeg ifd0.make: apple ifd0.model: iphone 4s ifd0.orientation: 6 ifd0.xresolution: 72/1 ifd0.yresolution: 72/1 ifd0.resolutionunit: 2 ifd0.software: 6.1.3 ifd0.datetime: 2013:04:17 15:13:39 ifd0.ycbcrpositioning: 1 ifd0.exif_ifd_pointer: 204 ifd0.gps_ifd_pointer: 594 thumbnail.compression: 6 thumbnail.xresolution: 72/1 thumbnail.yresolution: 72/1 thumbnail.resolutionunit: 2 thumbnail.jpeginterchangeformat: 890 thumbnail.jpeginterchangeformatlength: 7684 exif.exposuretime: 1/20 exif.fnumber: 12/5 exif.exposureprogram: 2 exif.isospeedratings: 50 exif.exifversion: 0221 exif.datetimeoriginal: 2013:04:17 15:13:39 exif.datetimedigitized: 2013:04:17 15:13:39 exif.componentsconfiguration:  exif.shutterspeedvalue: 2779/643 exif.aperturevalue: 4845/1918 exif.brightnessvalue: 13523/4727 exif.meteringmode: 3 exif.flash: 16 exif.focallength: 107/25 exif.subjectlocation: array exif.flashpixversion: 0100 exif.colorspace: 1 exif.exifimagewidth: 3264 exif.exifimagelength: 2448 exif.sensingmethod: 2 exif.exposuremode: 0 exif.whitebalance: 0 exif.focallengthin35mmfilm: 35 exif.scenecapturetype: 0 gps.gpslatituderef: n gps.gpslatitude: array gps.gpslongituderef: w gps.gpslongitude: array gps.gpsaltituderef:  gps.gpsaltitude: 55556/297 gps.gpstimestamp: array gps.gpsimgdirectionref: t gps.gpsimgdirection: 19688/145

here code use php script photos, removed header , requires:

<?php require('[...]'); mysql_select_db($db_name, $oconn);  $jobnum = $_post['jobnum'];  if ((($_files["file"]["type"] == "image/gif")     || ($_files["file"]["type"] == "image/jpeg")     || ($_files["file"]["type"] == "image/pjpeg"))     && ($_files["file"]["size"] < 10000000)) {     if ($_files["file"]["error"] > 0)     {         ps_log( "bad photo upload - return code: " . $_files["file"]["error"]);     }     else     {         ps_log( "upload: " . $_files["file"]["name"]);         ps_log( "type: " . $_files["file"]["type"]);         ps_log( "size: " . ($_files["file"]["size"] / 1024) . " kb");         ps_log( "temp file: " . $_files["file"]["tmp_name"] . "<br />");          $photoname = $_files['file']['tmp_name'];         $root = "[...]";         $location = $_server['document_root'].$root.$photoname;         $exif = exif_read_data($photoname, 0, true);          $filename = $exif["file"]["filename"];         $model = $exif["ifd0"]["model"];         $date = $exif["ifd0"]["datetime"];         $lon = $exif["gps"]["gpslongitude"];         $lonref = $exif["gps"]['gpslongituderef'];         $lat = $exif["gps"]["gpslatitude"];         $latref = $exif["gps"]['gpslatituderef'];           $lon = photos::getgps($lon, $lonref);         $lat = photos::getgps($lat, $latref);          $photo = new uploadedphoto();         $photo->jobnum = $jobnum;         $photo->tempfile = $_files["file"]["tmp_name"];         $photo->filename = $_files["file"]["name"];         $photo->comments = $_post['comment'];           $photo->model = $model ;   $photo->datestamp = $date ;   $photo->lat = $lat ;   $photo->lng = $lon ;         $photo->savegeo();     } } else {     echo "invalid file"; }  header("[...]");?>

only thing can create native app (or apache cordova app), handle upload. gps data stripped mobile safari. app should upload picture as-is. of there no other way around it.

it may along these lines: http://gonzalo123.com/2013/10/28/taking-photos-with-a-phonegapcordova-application-and-uploading-them-to-the-server/

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
