php - I can not insert a value with apostrophe in the database -


i cant save value of select option: if value "t'est" cant save full string "t'est" in database. 

if(isset($_post['ul'])){                 $festival_type = addslashes(mysql_escape_string($_post['tf']));     $query = mysql_query("insert festival (festival_name) values ('".$festival_type."')");                 echo "success!"; }

warning: mysql_escape_string() extension deprecated of php 5.5.0, , removed in future. in case should use 1 escape rule.

if $_post['ul'] have word "t'est" , should save quote $festival_type have "t\'est" using addslashes. after mysql receive: insert festival (festival_name) values ('t\'est') means in database save t'est no problem.

if(isset($_post['ul'])){     $festival_type = addslashes($_post['tf']);     $query = mysql_query("insert festival (festival_name) values ('".$festival_type."')");                 echo "success!"; }

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!
