php - Struggling to get this to upload into my database - 


// check status. if (!empty($_session[username])) { echo "hi, <b>$_session[username]</b>.";  if ($_post['submit']) {      //get file attributes     $name = $_files['myfile']['name'];     $tmp_name = $_files['myfile']['tmp_name'];  if ($name) {     //start upload process      $location = "avatars/$name";     move_uploaded_file($tmp_name,$location);          $query = mysql_query("update members set imagelocation='$location' username='$username'");          die("your image has been uploaded! <a href='dashboard.php'>back</a>");   } else die("please select file"); } echo "upload image:  <form action='profile.php' method='post' enctype='multipart/formdata'>  file: <input type='file' name='myfile'> <input type='submit' name='submit' value='upload'></form>";  }

its showing username fine, have correct tables , columns in db when hit upload nothing?

you can see logging in username: test password: test url: learning.iamdanbarrett.com

i think there problem in query 

$query = mysql_query("update members set imagelocation='$location' username='$username'");

because not defining $username variable anywhere in script hence, query checking like

update members set imagelocation='$location' username ='';

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
