How to reload a custom library - zashishz - 05-19-2017

I have created a custom library which depends on session data.

In my main controller i am initializing session values and want to reload custom library based on new values every time page is refreshed.
Hence, i am using session_destroy(); at the end of my controller method.

But on page refresh library are not reloaded : 

Code:
closeOrders class already loaded. Second attempt ignored.



Is there any way i can reload some library again on page refresh.

This has nothing todo with a page reload. This means you are loading that library twice

PHP Code:
$this->load->library('closeOrders'); 

Because a resource is appended to the CI super object, you can't load a resource twice.
If you provide an alias name for a library as a third argument when loading it, CI will create a new instance of that class and append it to the super object using the provided alias.

You can also just do this
PHP Code:
$second_closeOrders_object = new closeOrders(); 

Because the file is loaded into memory you can create a new instance of the class where ever you may need it.

If you don't want to do this, and want to re-use the first instance, create a method in the library that resets it be clearing all the variables

PHP Code:
$this->closeOrders->clear($new_values);

Thanks for the reply.
I wanted to reload library to populate with updated session data.


Now using Session Flash Data to refresh data on every request and its working fine.
