Question

So I thought I’d write my first codeigniter helper (still new to codeigniter somewhat). I needed something that would return an array of filenames from a photo directory to make hyperlinks to them. This was so I wouldn’t have to write out each filename myself, and adding new photos to the directory dynamically updated the site.

So I made a new helper called photo_helper.php which looks like this:

<?php 

    function spit_out_images($path)
    {
        $aryPhotos = get_filenames($path);

        //does parsing to create hyperlinks

        return $aryPhotos;
    }

I set the file and photo helper to autoload inside my autoload.php

Then in my view I called the helper function spit_out_images like so:

<?php
      $photoPath = base_url().'assets/_images/TwentyYears/thumbs';
      echo spit_out_images($photoPath);

?>

But I never get any results out. I even tried echoing out the $photoPath variable to make sure it was giving out the path correctly, which it was.

I’m sure it is something simple I’m missing, I just can’t figure it out.

Thank you!

Make sure base_url() . 'assets/_images/TwentyYears/thumbs' has the correct permissions for Apache/PHP to execute and read the directory and files, 0755 should be an appropriate mode.
