I am struggling to update my MySQL database.
This is what I have written:

$mysql_link = mysql_connect('servername','username','password');
mysql_select_db('bambi4couk_599731_db3', $mysql_link);

$serializedTemplates = serialize($_SESSION['data']['user']['templates']);
mysql_query("UPDATE rmusers SET templates='$serializedTemplates' WHERE email='" . $_SESSION['data']['user']['details']['email'] . "'");

How can I fix this to make it work?

EDIT:

I am not getting an error but the function is not updating the database and it is returning false.

$_SESSION[‘data’][‘user’][‘details’][’email’] returns the email address used (which does appear in the database).

The serialized array is too long to paste here but there are no problems with it – it is a string anyway so I don’t see how it could be wrong.

EDIT2:

As it turned out my assumption was wrong, the serialized array had to be escaped first.

    Add 

     or die (mysql_error());

    Like this

    mysql_query("UPDATE rmusers SET templates='$serializedTemplates' WHERE email='" . $_SESSION['data']['user']['details']['email'] . "'") or die (mysql_error());

    Then tell us what the error message is, so we can help you

    At a guess I would expect you have not escaped the values

    see mysql_real_escape_string()
