Pop Custom PHP Warning Message in Codeigniter

Today I will tell you how to pop custom warning/error message in Codeigniter. Few days ago I was working on a project in codeigniter and I needed to show some custom warning messages on user interface so I dig back into Codeigniter and found something that I would like to share with you.

It is just few lines of code that you should put on your main controller so you can call it any where in your controller and also you can use it in any of your model by putting this code in main model.

For main controller:

public function custom_error($severity, $message){
$debug_data = debug_backtrace();

_exception_handler($severity, $message, $debug_data[0]['file'], $debug_data[0]['line']);
}

Now we can call it in any controller using below syntax.

$this->custom_error('PHP error', 'Some PHP error occured.');

Same in the main model:

public function DB_custom_error($severity, $message){
$debug_data = debug_backtrace();

_exception_handler($severity, $message, $debug_data[0]['file'], $debug_data[0]['line']);
}

I hope it helped you, good luck!!
