问题 I am using codeigniter and its routes system successfully with some lovely regexp, however I have come unstuck on what should be an easy peasy thing in the system. I want to include a bunch of search engine related files (for Google webmaster etc.) plus the robots.txt file, all in a controller. So, I have create the controller and updated the routes file and don't seem to be able to get it working with these files. Here's a snip from my routes file: $route['robots\.txt|LiveSearchSiteAuth\.xml

问题 I want to get the time from 12:00:00 PM to 02:00:00 PM but it doesn't work when I use start_time >= '12:00:00' AND end_time <= '02:00:00' . I have this code so far.

问题 Because of some bug or my lack of knowledge in ODBC connections I can't use CodeIgniter's $this->db->like(); (If you really want to know why I can't use it, see my other thread here.) How do I replace $this->db->like("name", 'a', 'after'); with some other safe code? EDIT: Obviously, I wasn't clear in my description. I KNOW how to use "like()". My problem is that I CAN'T use it because of other circumstances. What I need is a substitute for "like()". I know I could do it like: $this->db->where

问题 How would I autoload the database using autoload.php I already got the autoloading of course... that's the easy part. But also allowing me to check if the db has been connected to, and if not, to display a specific page saying something like "We are sorry but our database is currently unavailable." Would it have to be some kind of custom hook that I would have to make? 回答1: You can edit the error template in application/errors/error_db.php to use your custom message. Maybe use the ENVIRONMENT

问题 I've got a page that contains 4 products loaded from the database, when you scroll down you get 4 more products every time. This products are loaded in a random way, the problem are the duplicate products. This is the line that I used into the model: $this->db->order_by('productID', 'RANDOM'); Without this line everything works fine. I can't use limit set to 1 because I've got: $query = $this->db->get('product', 4, $offset); There's a simple way to solve this problem? I've to do an array that

问题 I am using Codeigniter 2.1.4 and I have facing some issues with flashdata. When I successfully submit record I can display the flashdata message. But if go to the other page from the page where flashdata message was displayed and then go back to previous page using browser back button it shows me flashdata message again.

问题 OK, so I'm trying to do this: !www -> www http -> https EXCEPT /[a-f0-9]{11}/ https://www.domain.com/[a-f0-9]{11}/ -> http://www.domain.com/[a-f0-9]{11}/ map to controller: index.php?(uri) e.g. /controller/action/id -> index.php/controller/action/id Summary: all URLs should be https://www.domain.com/(.*) except /[a-f0-9]{11}/, which should be forced to http only.
