   I am attempting to create my own plugin, and am running into a fatal error when I attempt to activate it. I cannot figure out why. As of now, the only thing the plugin does is create a new DB table at activation. Here is the code

   $rbVersion = "1.0";
   
   //install DB tables
   function rb_install() {
   	global $wpdb;
   
   	//first check to see if the DB table already exists
   	$tableName = $wpdb->prefix . "rusty_beard";
   
   	if($wpdb->getvar("SHOW TABLES LIKE '" . $tableName . "'") != $tableName) {
   		//create DB tables
   		$install = "CREATE TABLE " . $tableName . "(
   				field_id  KEY INT NOT NULL AUTO_INCREMENT,
   				field_name VARCHAR(50),
   				field_type VARCHAR(50),
   				field_default VARCHAR(240),
   				field_required INT,
   				field_label VARCHAR(240)
   				field_order INT)";
   
   		require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
   
   		dbDelta($install);
   
   		//add version to DB
   		add_option("rb_version", $rbVersion);
   
   	}
   }
   
   //install the plugin
   register_activation_hook(__FILE__, 'rb_install');

   This is all located in the main plugin file, the only plugin file I have.

   When I attempt to activate it, WP gives the following error:

   Plugin could not be activated because it triggered a fatal error.
   
   Fatal error: Cannot redeclare rb_install() (previously declared in /home/dir/public_html/dir/wp-content/plugins/RustyBeard/rusty_beard.php:21) in /home/dir/public_html/dir/wp-content/plugins/RustyBeard/rusty_beard.php on line 45

   I am having the same problem. I see you have other threads about register_activation_hook. Did you get it resolved?
