codeigniter

问题 Fairly new to CodeIgniter, still grasping the MVC approach. I'm just wondering what's the best way to solve this: I got my navigation bar highlighting the currently active link like so: <a href="index.hml" id="active">Index</a> <a href="blog.hml">Blog</a> Now, when I go to blog.html I want id="active" to shift accordingly. Usually I'd assign a variable to each link and then set it's value to 'id="active'. Somehow I don't think that's the best way. Any thoughts? Update (12. Sept 2012) Since

问题 I want to make an import script which allows users to upload their excel file (extension not important) to my php application. The application should reconize a list of items (so far so good). The difficulty in this case is that the excel files contain images... I've read information about phpexcel library but it does not say anything about images. Anybody ideas? 回答1: You can access images by PHPExcel library. For importing images: $objPHPExcel = PHPExcel_IOFactory::load("MyExcelFile.xls");

问题 I'm currently trying to build a new website, nothing special, nice and small, but I'm stuck at the very beginning. My problems are clean URLs and page navigation. I want to do it "the right way". What I would like to have: I use CodeIgniter to get clean URLs like "www.example.com/hello/world" jQuery helps me using ajax, so I can .load() additional content Now I want to use HTML5 features like pushstate to get rid of the # in the URL It should be possible to go back and forth without a page

问题 In Codeigniter 2.1.2 I want to create base controller and then extends from this controller. It does not work and I have no idea why and I'm pretty desperate now. In \application\core\MY_Base_Controller.php I have this: <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class MY_Base_Controller extends CI_Controller { function __construct() { parent::__construct(); ... In \application\controllers\Home.php I have this: <?php if ( ! defined('BASEPATH')) exit('No direct

问题 I'm developing a WebApp with Codeigniter 3, Facebook SDK and this this library for manage the request. Using the main tutorial for Facebook Login all things work fine. An example here: <?php $login = $this->facebook->login_url(); ?> <a href="<?=$login;?>"> Login with your Facebook account </a> After that I can do any request with the access token. With the new update, facebook apps must activate the Strict Mode for Redirect URIs. So in the developer portal I've activated my urls like this:

问题 I have a site which does a few ajax calls on page load. For some reason, CodeIgnitor is inserting 4 sessions (I'm assuming one for each ajax call) as you load the page. I'm storing the sessions in the database. I'm pretty sure there should only be one session per browser. Firefox seems to generate only one; other browsers seem to create a whole bunch of sessions. Multiple sessions for the same user are giving me some serious authentication problems. Why is this happening? How can I stop it?
