问题:

i have developed a web app on code igniter .. this is the first time i am working on code-igniter .. after developing a web application on my localhost .so i decided to put my code-igniter web app on the temporary free server.. so i uploaded my site on this site 1freehosting... and then i imported my database .. after that i have changed the settings of database in database.php file .. and also i changed the base url in config.php file ..as this is my domain name http://hello.hostingsiteforfree.com/... so i changed it to this url .. but then i am getting a following error ... i dont know what is going wrong ..i have searched a lot but nothing helps.. and also i am forgot to mention that my .htaccess file is empty ..means there is not a single line in it

this is the error i am getting

回答1:

Since you do not have any .htaccess to edit you url you must add an index.php when calling a controller like

http://hello.hostingsiteforfree.com/index.php/loginController

I tried accessing it via the url above and it works, but the database connection is not set up properly

in your config file where there is $config['index_page'] = '' if it is blank add an index.php to it

Check to see it works

Look at your application/routes.php and make sure that your $route['default_controller'] is correctly set to your default controller. As follows, this is my routes.php:

$route['default_controller'] = "home";
$route['404_override'] = '';

Also, make sure that your default controller (in my case, its application/controllers/home_controller.php and within it is class Home extends CI_Controller {...}

--

If that doesn't work, make sure your default controller is correctly calling your default view and loading it as such:

$this->load->view('home_view', $data);

--

If THAT doesn't work, then take a look at your application/config/config.php and make sure that the following are correctly set as follows IF you want to get rid of your index.php in the url (for clean urls):

$config['index_page'] = ''; $config['uri_protocol'] = "AUTO";

and if you're going for clean urls, do post your .htaccess (which should follow something like this: http://www.farinspace.com/codeigniter-htaccess-file/) so we can look at it in further detail and try to fix it if none of the above fix it.

Have you removed index.php with .htaccess? If not then put it in the end.
