Plugin uninstall,php

From Jomres v4 manual

Do whatever you need to do here to drop any plugin's database tables/clean up files that might be been put outside of the remote_plugins/dummy_third_party_plugin directory by this plugin. Jomres will handle the removal of the dummy_third_party_plugin remote plugins folder itself.

eg.

$table_name = " #__jomres_thirdpartyplugin_dummy_third_party_plugin";
 
$query= "DROP TABLE IF EXISTS `".$table_name."`";
echo "Dropping table ".$table_name." <br>";
if (!doInsertSql($query,'') )
	echo "<b>Error, unable to drop table ".$table_name."</b><br>";
	}
