URLs Your URLs should typically be all lowercase letters. If you expect capital letters, there’s a chance you could accidentally exclude their lowercase counterparts, even though they’re the same URL. Example: www.example.com/controller/method/param Controllers Controller class names should be all lowercase, except the first letter. If your URL is www.example.com/gallery, the controller name is Gallery. If … Read more
I believe you’ll want something like this: $this->db->select(‘user_id, COUNT(user_id) as total’); $this->db->group_by(‘user_id’); $this->db->order_by(‘total’, ‘desc’); $this->db->get(‘tablename’, 10); This will produce a result like | USER_ID | TOTAL | | 12 | 3 | | 15 | 2 | | 18 | 1 | UPDATE: As some pointed out in the comments the original query was summing … Read more
It seems the problem is you send the form request to welcome/do_upload, and call the Welcome::do_upload() method in another one by $this->do_upload(). Hence when you call the $this->do_upload(); within your second method, the $_FILES array would be empty. And that’s why var_dump($data[‘upload_data’]); returns NULL. If you want to upload the file from welcome/second_method, send the … Read more

I got it working by adding cbrandolino‘s suggested mimetypes to the config/mimes.php (great tip jljohnstone). So the csv property of my $mimes looks like this now: ‘csv’ => array(‘application/vnd.ms-excel’, ‘text/anytext’, ‘text/plain’, ‘text/x-comma-separated-values’, ‘text/comma-separated-values’, ‘application/octet-stream’, ‘application/vnd.ms-excel’, ‘application/x-csv’, ‘text/x-csv’, ‘text/csv’, ‘application/csv’, ‘application/excel’, ‘application/vnd.msexcel’)
I encountered exactly the same problem. To solve it I have a MY_REST_Controller.php in core and all my REST API controllers use it as a base class. I simply added a constructor like this to handle OPTIONS requests. function __construct() { header(‘Access-Control-Allow-Origin: *’); header(“Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method”); header(“Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, … Read more
You can add rewrite rules in your web.config file. Add the following to the system.webServer section: <rewrite> <rules> <rule name=”Rule” stopProcessing=”true”> <match url=”^(.*)$” ignoreCase=”false” /> <conditions> <add input=”{REQUEST_FILENAME}” matchType=”IsFile” ignoreCase=”false” negate=”true” /> <add input=”{REQUEST_FILENAME}” matchType=”IsDirectory” ignoreCase=”false” negate=”true” /> <add input=”{URL}” pattern=”^/favicon.ico$” ignoreCase=”false” negate=”true” /> </conditions> <action type=”Rewrite” url=”index.php/{R:1}” appendQueryString=”true” /> </rule> </rules> </rewrite>

You shouldn’t load image_lib in foreach. Try to use code below $this->load->library(‘image_lib’); foreach($results as $row) { $config[‘image_library’] = ‘gd2’; $config[‘source_image’] = ‘/img/proizvodi/’.$row->proizvodid.’.jpg’; $config[‘create_thumb’] = TRUE; $config[‘maintain_ratio’] = TRUE; $config[‘width’] = 75; $config[‘height’] = 50; $this->image_lib->clear(); $this->image_lib->initialize($config); $this->image_lib->resize(); } If it wont work – check the upload folder permissions.
