Hi Khanbaba,
the problem is not related to your stored procedure.
mysql_connect doesn't return an object but a resource pointer. Therefore you cannot use

$resource = mysql_connect(...);
$resource->prepare(...);

You have probably confused it with mysqli() set of functions:

$mysqli = new mysqli(...);
$stmt = $mysqli->prepare(...);

btw: if you want to display a value of $author_keyword you have to type echo $author_keyword; not just $author_keyword;
