Edit a file inside database in php -


when submit button pressed,the isset($_post['ta'] works,but file not updated inside database '---------'. suggestion going wrong?

if ( isset( $_post['ta'] ) ) {     $handle = fopen('saw42.textgrid', "a");     require('db_connection.php');     fwrite( $handle, "-----------");     fclose( $handle ); }

try this

if(isset($_post['ta'])){       $handle=fopen('saw42.textgrid',"a");     require('db_connection.php'); // don't know why line here     if ($handle===false){         echo 'unable open file';     }else{         fwrite($handle,"-----------");         fclose($handle);     }  }

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!
