php - How to insert image into remote database by iOS app? -

in ios app, have store image in remote database. have done blob already.but want storing path only. have tried lot failing write client side code.

client side code:

nsdata *imagedata = uiimagejpegrepresentation(self.imgview.image,0.2);     //change image nsdata  if (imagedata != nil) {     nsstring *filenames = @"catttt.jpeg";      //set name here     nslog(@"%@", filenames);     nsstring *urlstring = @"http://localhost/insertintoimage.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=\".jpeg\"\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 body of post reqeust     [request sethttpbody:body];     // lets make connection web     nsdata *returndata = [nsurlconnection sendsynchronousrequest:request returningresponse:nil error:nil];     nsstring *returnstring = [[nsstring alloc] initwithdata:returndata encoding:nsutf8stringencoding];     nslog(@"%@",returnstring);     nslog(@"finish"); } 

remote side code:

    $target_path = "uploads/";     $target_file = $target_path . basename( $_files['userfile']['filenames']);      if(move_uploaded_file($_files['userfile']['tmp_name'], $target_file)) {         echo "the file ". basename( $_files['userfile']['filenames']) . " has been uploaded";     } else {         echo "there error uploading file, please try again!";     } ?> 

first upload image server , update image name/path db

below function store image server

here $image imagedata comes ios app

$image = $_post['image_name_from_app']; $image = str_replace("<", "", $image); $image = str_replace(">", "", $image); $image = str_replace("&lt;", "", $image); $image = str_replace("&gt;", "", $image); $image = preg_replace('/[\s\w]+/', '', $image); $bin = hex2bin($image); $path = "user_images/"; $imagename = time() .".png"; $path = "user_images/"; if (file_put_contents($path . $imagename, $bin)) {   return $imagename; } return false;
