jquery - Update MySQL using AJAX and PHP -


i'll go slow, not sake..for mine. i'm real new @ trying to this. i'm trying update live mysql db html table. how each built.

 echo ("<td id=\"callsign:$row[recordid]\" contenteditable=\"true\"                  onclick=\"showedit(this)\"                 onblur=\"savetodatabase(this,'callsign',$row[recordid])\"                  style='text-transform:uppercase'>                 $row[callsign]</td>");

this how renders.

 <td id="callsign:6" contenteditable="true" onclick="showedit(this)" onblur="savetodatabase(this,'callsign',6)" style="text-transform: uppercase; background-color: rgb(253, 253, 253); background-position: initial initial; background-repeat: initial initial;">                 ka0sxy</td>

here function gets called.

 function savetodatabase(editableobj,column,id) {          $(editableobj).css("background","#fff url(loadericon.gif) no-repeat right");             $.ajax({                 url: "saveedit.php",                 type: "post",                 data:'column='+column+'&editval='+editableobj.innerhtml+'&id='+id,                 success: function(data){                     $(editableobj).css("background","#fdfdfd");                 }               });       }

and here php.

 <?php require_once "dbconnectdtls.php";      $result = mysql_query("update netlog set " . $_post["column"] . " = '".$_post["editval"]."'  recordid=".$_post["id"]);     echo $result;   ?>

when tab cell next thing gets executed .gif. mysql not updated, doing wrong?

thanks in advance not treating me dummy, helping me learn.

followup suggestions:

i'm afraid i'm making no headway on this. willing write working example can follow?

for newcomer there many things should take care in script:

  1. first have avoid insertion of $_post values directly query may lead sql injection problems.
  2. you should use pdo or mysqli perform query same paranoidal reasons.
  3. you should consistent. why use .innerhtml when using jquery? use $(editableobj).html()
  4. you don't show javascript errors: viewing console? try right clicking in body of page , selecting "inspect element" click on "console" tab of frame appears.

  5. also not printing "data" variable gets returned see if expected result in server. with:

    console.log(data);

other looks in script ;)
