jquery - Error in update and insert query in php mysql -

-

i trying update seen(a bool in database) if seen button clicked , delete row if delete button clicked. doesn't seem work nor data(mysql_error) back. last else part works , data.

this php code :

if(isset($_post["seen"])){     $fid=$_post["id"];     $sql="update feedback set seen=1 id=$fid";     mysql_query($sql,$con);     echo mysql_error($con); } else if(isset($_post["delete"])){     $fid=$_post["id"];     $sql="delete feedback id=$fid";     mysql_query($sql,$con);     echo mysql_error($con); } else{     $sql="select * feedback";     $result=mysql_query($sql,$con);     while($row=mysql_fetch_array($result)){         $jsondata[]=$row;     }     echo json_encode($jsondata); }

and js code:

$("#seen").click(function(){     $.post("main_php.php",{},function(data){         alert(data);     });  });  $("#delete").click(function(){     var fid = $('#id').val();     $.post("main_php.php",{id:fid},function(data){         console.log(data);     })  });

please tell me may wrong it!!!!

seen , delete names of buttons btw

your jquery post not setting "seen" or "delete". when php executes, falling through last else.

in jquery, set "seen" or "delete" true (or else, need set) , should good.

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
