equivalent function for $this->_ci_cached_vars in CI Helpers

Question

I'm creating a custom helper in codeigniter. There is an instance where I check if certain parameter is passed to view.

In view, i can get all the passed variables by using this function:

$this->_ci_cached_vars

but it returns blank when used in the custom helper.

Is there any equivalent function of this that can be used in the helper?

Thanks in advance.

Answer 1

_ci_cached_vars is a property of the Loader class. So something like this should work (untested):

$CI =& get_instance();
$vars = $CI->load->_ci_cached_vars;

Answer 2

You can use $GLOBALS['CI']->load->get_var('your_key_here') tested in CI 2.1.2

Answer 3

I'm not sure if older versions of CodeIgniter support this, but in the v3 release the Loader class has a public method get_vars() that allows you to read the value of _ci_cached_vars.

Although this question is very old it's the first hit on Google that I found while searching for this problem. I hope this post helps someone out who follows the same path on Google as I did! :)
