Hi

I have been trying to delete an email address from a database and I get this error. I have checked the password and its ok.


Error Message: SQLSTATE[42000] [1044] Access denied for user 'ecovibdc_tudsy66'@'localhost' to database 'ecovib2d_Subscribers' Back to my blog - Try again !


3-Sep-2017 06:52:14 UTC] PHP Notice: Undefined variable: conn in /home/ecovibdc/public_html/ECOVIB2D/unsubscribe/unsubscribe.php on line 69
[13-Sep-2017 06:52:14 UTC] PHP Warning: mysql_close() expects parameter 1 to be resource, null given in /home/ecovibdc/public_html/ECOVIB2D/unsubscribe/unsubscribe.php on line 69



Thanks.

Most of your problems are PHP scope related, among other things. You define $conn inside the Delete() function then you try to use it outside of that function. You can't do that in PHP or any other language I know about. Variables defined in functions are only available to that function (unless you return the value). Also, in PHP global scope is different than in Javascript.

You create a database connection using PDO but then you try to use 'mysql*' methods. PDO has it's own methods, use them instead.

You didn't post the correct page for the 1st error message so I can't look into that.

Hi

Thanks for that.

I still get this error:

That is a database connection error message. Make sure your host, user name and password are correct.

Instead of creating your database connection in a function I would recommend you create a class and use it. This is a nice tutorial of doing that, http://culttt.com/2012/10/01/roll-your-own-pdo-php-class/. You still have a lot of research to do concerning PHP.
