   Good evening.
   I am newbie @ wordpress plugin programming.
   Briefly..
   In my index plugin file i am requiring once for functions file in which i have writen IF function for "if installation file (setup.php) exists -> include setup.php and register_activation_hook for table installation function".
   Here is setup.php code:
   

   //	Setting up table version for later upgrades
   	global $sarsauto_version;
   	$sarsauto_table_version	=	"0.1.";
   
   	//	Creating table
   	function sarsauto_table_setup() {
   		global $wpdb;
   		global $sarsauto_table_version;
   
   		$table_name = $wpdb->prefix . "sarsauto";
   
   		if( $wpdb->get_var( "show tables like '$table_name'" ) != $table_name ){
   			$sql = "CREATE TABLE " . $table_name . " (
   					id int(11) NOT NULL AUTO_INCREMENT,
   					UNIQUE KEY id (id)
   					);";
   		}
   
   		//	The dbDelta function examines the current table structure,
   		//	compares it to the desired table structure, and either adds
   		//	or modifies the table as necessary.
   		require_once( ABSPATH . "wp-admin/includes/upgrade.php" );
   		dbDelta( $sql );
   
   		add_option( "sarsauto_table_version", $sarsauto_table_version );
   	}

   And here is IF function of functions.php:

   //	Asking for setup.php file and if exists create function
   	if( file_exists( dINCLUDES . "setup.php" ) ){
   		//	Require setup.php file
   		include( dINCLUDES . "setup.php" );
   		//	On plugin activation ask for table setup function
   		register_activation_hook( __FILE__, "sarsauto_table_setup" );
   	}else{
   		echo "Error: file doesn't exists!";
   	}

   THE PROBLEM is whenever i am refreshing my database's list of tables, no new table is added (in this case 'sarsauto' table).
   I have done everything like in wordpress plugin creation documentation.
   Please help. This issue is making me crazy.
   Thanks in advance,
   Ricards
