Directory Helper Question

I am using the codeIgniter directory helper but have small question.

When I display my images and directory's in my foreach loop $image variable is a directory it throws error.

Error Message: Array to string conversion I have attached image of error.

PHP Code:

array (size=5)
  0 => string 'codeigniter.png' (length=15)
  1 => string 'CSS-Tricks-1024x469.png' (length=23)
  2 => string 'IMG_20151230_154130.jpg' (length=23)
  3 => string 'preypay.png' (length=11)
  'subfolder\' => 
    array (size=0)
      empty 


As shown in var dump sub folder is directory but when I echo out the foreach loop it throws error for that directory.

Any suggestion I need to display sub directory and images. Images I can display fine

PHP Code:

<?php

class Filemanager extends CI_Controller {

    public function index() {

    $this->load->helper('directory');

    $data['images'] = array();

    // Finds and loads images and directorys.
        
        $images = directory_map('./images/catalog/', FALSE, TRUE);

        var_dump($images);

        foreach($images as $image) {

            $data['images'][] = array(
                'img' => $image
            );

        }

        $this->load->view('filemanager_view', $data);

   }
} 


View

PHP Code:

<div class="container" style="margin-top: 20px;">
<div class="row">

<?php if ($images) {?>

<?php foreach ($images as $image) {?>

    <div class="col-lg-3">
        <a class="thumbnail">
              <?php echo $image['img'];?>
        </a>
        <div class="caption text-center">
        </div>
      </div>

<?php }?>

<?php } else {?>

    <div class="col-lg-12 col-md-12 col-sm-12">
        <h3>No images available</h3>
    </div>

<?php }?>
</div>
</div>

There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!

Try casting $image ie; (string) $image etc;

What did you Try? What did you Get? What did you Expect?

that's because 'subfolder' key is not a string but an array.

remove the key 'subfolder' with the unset() method from your array and everything is gonna be ok

unset($images['subfolder']);

but if you have images in your subfolder, you can use a recursive method.

a recursive methods is a method who call itself

PHP Code:

$images_directory = directory_map('./images/catalog/', FALSE, TRUE);
$images = array();

function getImages($images_directory){
    foreach ($images_directory as $image_directory){
        if (is_array($image_directory){
           getImages($image_directory);
        }else{
            $images[] = $image_directory;
        }
    }
}


getImages($images_directory);
var_dump($images); 


i'm not sure this methods work like that. i writted it from scratch. but this is how to do a recursive method.

I am just a bit confused will that let me still display the folders as well as images and there file names?

Seem to  have it working now by using scandir and array_diff

PHP Code:

<?php

class Filemanager extends CI_Controller {

    public function index() {

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

        $data['images'] = array();

        $directory = scandir(FCPATH . 'images/catalog', 1);

        $files = array_diff($directory, array('.', '..'));

        var_dump($files);

        foreach($files as $file) {

            $image = FCPATH . 'images/catalog/' . $file;

            if (is_dir($image)) {
                
                $data['images'][] = array(
                    'test' => ''
                );

            } else {

                $data['images'][] = array(
                    'test' => $file
                );

            }

        }

        $this->load->view('filemanager_view', $data);
    }
}
