JQuery向用户输入添加斜杠（textarea）

Question

I'm creating a user profile that updates into a database using JQuery Post and I've just noticed that if I use the word can't in the textarea it uploads to the database as can/'t and reads that back on the profile. My request in the php looks like this:

$name = mysqli_real_escape_string($con, $_REQUEST["name"]);
$location = mysqli_real_escape_string($con, $_REQUEST["location"]);
$about = mysqli_real_escape_string($con, $_REQUEST["about"]);

So is there anything I can add to prevent a slash being added?

As other people already said in the comments it's all because of magic quotes:

Disabling Magic Quotes - manual

If you can't disable them and do not want to change your code you can insert this snippet in your files.

  if (get_magic_quotes_gpc())
  {
    function stripslashes_gpc(&$value)
    {
      $value = stripslashes($value);
    }
    array_walk_recursive($_GET, 'stripslashes_gpc');
    array_walk_recursive($_POST, 'stripslashes_gpc');
    array_walk_recursive($_COOKIE, 'stripslashes_gpc');
    array_walk_recursive($_REQUEST, 'stripslashes_gpc');
  }
