javascript - Can't Accept Text in jQuery Editable -

i using following create text field "ok" , "cancel" options entering new text:

 $('.edit_area.entry').first().editable('ajax-save-entry.php', {       type      : 'textarea',      cancel    : 'cancel',      submit    : 'ok',      indicator : '<img src="img/indicator.gif">',      tooltip   : 'click edit...'  }); 

i have in html:

'<div id="' . $system->systemid . '" class="edit_area entry">' . $system->description . '</div>' 

this ajax-save-entry.php:

<?php  if(isset($_post['id'])){      $system = system::find_by_id($_post['id']);      if($system){          $system->description = $_post['value'];          $system->save();          echo $system->description;          } else {              echo "cannot find system system id";         }   } else {  echo "no system id set";  }  ?> 

i can type text , cancel it, clicking "ok" seems nothing. not sure if php code not running or if stopping before there. ideas?

edit: using this plugin.

if tell plugin you're using, optimal. i'm going assume you're talking this one since it's popular/standard (i think).

anyway, thing you're missing callback function handle you're echoing onto php page.

$('.edit_area.entry').first().editable('ajax-save-entry.php', {       type      : 'textarea',      cancel    : 'cancel',      submit    : 'ok',      indicator : '<img src="img/indicator.gif">',      tooltip   : 'click edit...',      callback  : function(data) {           //the data variable whatever php script echoed      } });
