Php – Codeigniter: user defined helper function does not load

codeignitercodeigniter-classloadercodeigniter-helpersPHP

I made a custom helper extending the system string_helper.php.

I placed it in my /application/helpers directory, called it MY_string_helper.php as required, unit-tested its functions.

Now, when I try to call one of its functions from a model, it does not work.

The functions in the default string helper work, instead. It looks like my extension is not loaded for some reasons.

Thanks a lot, and happy holidays.

Edit: even funnier. I saved the file as categories_helper.php in the system/helpers directory, and when I try to load it within a model i got the following response: *Unable to load the requested file: helpers/categories_helper.php*

I had the same problem. I came from windows OS development of my codeigniter project, then shifted to Ubuntu, but somehow it still didn't load my helpers.

I found that changing the naming convention to lowercase solves the problem. Don't follow what's written in the doc where you are given a prefix to insert, especially if it's in uppercase. Make use of lowercase.

Php – CodeIgniter: Create new helper

A CodeIgniter helper is a PHP file with multiple functions. It is not a class

Create a file and put the following code into it.

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

if ( ! function_exists('test_method'))
{
    function test_method($var = '')
    {
        return $var;
    }   
}

Save this to application/helpers/ . We shall call it "new_helper.php"

The first line exists to make sure the file cannot be included and ran from outside the CodeIgniter scope. Everything after this is self explanatory.

Using the Helper

This can be in your controller, model or view (not preferable)

$this->load->helper('new_helper');

echo test_method('Hello World');

If you use this helper in a lot of locations you can have it load automatically by adding it to the autoload configuration file i.e. <your-web-app>\application\config\autoload.php.

$autoload['helper'] = array('new_helper');
