Here is the relevant code in my controller: // In order to properly build the form url, we need to include the // category and product to the view $this->data = array( 'category' => $category, 'product' => $product ); // Load the product model and get editable values from the database $this->load->model('productadmin/products_model'); $productInformation = $this-

问题 I have a website that allows people to post things. When they post, it gets inserted into the database and the database adds a timestamp. When I hosted the database on my local machine, the timestamps were in my time zone. My new hosting website has it set to GMT time. How can I make it display the time in my time zone?

问题 I am using a pre controller hook to detect and set the site language from the session/cookie/browser lang detection.. something like this answer: Codeigniter language I am also using the famous Tank Auth library to manage users and I am using the codeigniter Session class to store and manage the users sessions upon log in. Each user can specify the interface language he wants and store it in the database for future log ins. The lang info is copied from the DB to the session on every log in.
