My foreach loop picks up files and folders. But I am still having issue because when original_image is a folder it throws error.

Code:

A PHP Error was encountered

Severity: Notice

Message: Array to string conversion

Filename: controllers/Filemanager.php

Line Number: 204

Backtrace:

File: C:\wamp\www\project-2-upload\application\controllers\Filemanager.php
Line: 204
Function: _error_handler

File: C:\wamp\www\project-2-upload\application\controllers\Filemanager.php
Line: 91
Function: resize

File: C:\wamp\www\project-2-upload\index.php
Line: 292

I am not sure the best method of where to use if is file or a if is dir?

Because I use a input get as well.

Any suggestions?

PHP Code:

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

$get_directory = $this->input->get('directory');

if (isset($get_directory)) {
    $cached_images = directory_map('./images/cache/' . $get_directory);
} else {
    $cached_images = directory_map('./images/cache/catalog/');
}

foreach ($cached_images as $position => $image) { 

    $original_image = str_replace('_thumb-' . $width . 'x' . $height, '', $image);

    $path = '';

    if (isset($get_directory)) {
        $path = '/' . $get_directory . '/' . $original_image;
    } else {
        $path = '/catalog/' . $original_image; // Line 204
    }

    var_dump(FCPATH . 'images'. $path);
                    
}

The directory_map() function gives you back a nested array. If you loop through it you should perform an extra verification to check if the value is a string (containing your image file name) or an array (containing all the files in the sub directory).

PHP Code:

foreach ($cached_images as $position => $image) { 
  if (is_string($image)) {
    ...
  }
}

thanks for that I will read more on is_string that is a new one for me.
