all users notice here if they want to use tinymce and they get error like this so they must have to enter there table like this 
`mysql_real_escape_string($sql_table).
`
so my code is like this 

$query = 'INSERT into notes VALUES(NULL, "'.date("Y-m-d").'", "'.$note_title.'")

so i just add mysql_realescape_string

$query = 'INSERT into notes VALUES(NULL, "'.date("Y-m-d").'", mysql_real_escape_string($notetitle))

and it works but it show me 

> Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: A link to the server could not be established i

so for that you have to add this in before that $query thing :)

    $con = mysql_pconnect("localhost","users","password");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }	

and you'r done ..... thanks for all help
