[FIXED] What is Cache Tagging?

Issue

There is Cache_Tagging in Kohana but it does not explain what it is. Can anyone tell what Cache Tagging is supposed to do or when do we use it ?

Solution

Some cache implementations allow you to add one or more tags to any data item you store in the cache, and then find or delete all items with a given tag. This can be useful for a number of things, most significantly batch updates (you add a bunch of related stuff to the cache, tag it with a version string, and when you later learn that data from that version has become outdated, tell the cache to drop it all at once).

[FIXED] Why does PHPExcel try to create a class name out of the Excel file name when used inside Kohana?

Issue

I am trying to build the PHPExcel library into an application built with the Kohana PHP framework.

In a test app outside the Kohana framework, I can create and read Excel files fine.

And inside the Kohana application, creating a file works:

$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setCreator("Test Generator")
    ->setTitle("Test Excel5 File");
$objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1', 'Hello');
$objPHPExcel->getActiveSheet()->setTitle('Test Sheet');
$objPHPExcel->setActiveSheetIndex(0);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('test123.xls'); //created in the root directory of application

However, when inside the Kohana framework when I try to read a file with this code:

$objReader = PHPExcel_IOFactory::createReader('test123.xls');

I get this error:

How can I prevent PHPExcel/Kohana from trying to create a class name out of the Excel file name?

Solution

The createReader() method expects the filetype as a parameter (eg Excel2007, Excel5, Excel2003XML, OOCalc, Gnumeric, CSV), not the filename.

// Use the IOFactory to instantiate a reader of the correct type
$objReader = PHPExcel_IOFactory::createReader('Excel5'); 
// Use the reader to load the file, and return a PHPExcel object
$objPHPExcel = $objReader->load('test123.xls');

[FIXED] Routing in Kohana in development

Issue

I am setting up my new web application using the Kohana framework.

I am using MAMP so the app is located in the htdocs folder, with this structure:

---htdocs
 --foo
  -application

I am getting this error when viewing http://localhost:8888/foo/

Kohana_HTTP_Exception[ 404 ]: The requested URL foo was not found on this server.

In the bootstrap.php the route is the default Kohana one

Route::set('default', '(<controller>(/<action>(/<id>)))')->defaults(
array(
    'controller' => 'welcome',
    'action'     => 'index',
));

Solution

Check your application/bootstrap.php file for:

Kohana::init(array(
    'base_url'   => '/foo/',
));

This is required for Kohana to understand it's in /foo/ folder.

UPD The requested URL foo was not found on this server exception message is generated if no action_<action> method was found in Controller.

If no Route was found Unable to find a route to match the URI: exception message is genereted.

Not shure Routing works as expected, but it works ;).

So check your Controller file for apropriate action method.

[FIXED] kohana framework doesn't load module on linux server while load it perfectly on mamp

Issue

well, question is in subject, here i can give you some details. Error is Class QIWI is not found. In bootstrap it is uncommented, when i use

    Debug(Kohana::modules()) 

it shown like module is loaded. folder three is

    --modules
    --|-qiwi
    ----|--classes
    -------|--Kohana
    ----------|--Qiwi.php (class Kohana_Qiwi)
    -------|Qiwi.php (class Qiwi extends Kohana_Qiwi)

i think that is a filename issue, but it seems like files r named correctly

Solution

Try to uncomment this line in bootstrap:

spl_autoload_register(array('Kohana', 'auto_load_lowercase'));
