问题 I need to create a query log in my project. So I created a post_controller hook. It saves all the executed queries in both a text file and a database. But it works only for SELECT queries. I know it is repeated question, but after a lot of search, I couldn't find solution. Here is my code: config/hooks.php: $hook['post_controller'] = array( 'class' => 'LogQueryHook', 'function' => 'log_queries', 'filename' => 'log_queries.php', 'filepath' => 'hooks' ); hooks/log_queries.php class LogQueryHook

问题 I'm trying to upload several files at once from ONE input : <input type="file" name="form-image[]" id="form-image" multiple="true" /> Which itself without CodeIgniter works fine.

My faulty code so far: //Iterate through each file uploaded for (

问题 I've created a "validation helper" that was supposed to have all my custom validation rules. The problem is that when I use them in my form validation, they seem to be ignored. If I move the functions in the controller that is doing the form validation, everything works like a charm. My validation helper is autoloaded. Is there any reason why I can't seem to use these validation functions if I put them in a helper? Thanks. 回答1: A function in a helper and a controller are different obviously.
