Fatal error: Call to undefined function get_instance() - El Forum - 12-13-2007 [eluser]kelye[/eluser] hello i have the following problem... Code: MY_Input.php and i get a "Fatal error: Call to undefined function get_instance() ..." Fatal error: Call to undefined function get_instance() - El Forum - 12-13-2007 [eluser]kelye[/eluser] ok... found the problem Input is a core class that loads and instantiates automatically BEFORE the Base4/5.php loads (where get_instance() is) i think it would be nice to add a clear warning in docs about this Fatal error: Call to undefined function get_instance() - El Forum - 12-13-2007 [eluser]tonanbarbarian[/eluser] Yes there are a few things that are loaded before the controller Once the controller is loaded a reference is made to the input class inside the controller so that you can access it there If you need to extend the input and you need to access the controller in it here is what I suggest still keep your CI property but do not instantiate it in the constructor create a seperate method that can check for an instantiate the CI property and call there in any new code that you write where you might need to access the controller. This way you dont break the input class and you only use the CI property when you needed it saving resources Code: class MY_Input extends CI_Input { Fatal error: Call to undefined function get_instance() - El Forum - 12-13-2007 [eluser]kelye[/eluser] thanks for the answer the only problem with your code is that i have to call the _inst() function after the script is initialized... and then i will have $CI available i've used some other functions instead of the resources needed from CI thanks again |
