opendir error with first two images codeigniter

Question

i am reading from a directory which everything it looks fine. I am able to display all the data inside the folder but i have a problem, in the beginning of the list it shows 2 broken images which are not mine they have a strange path it looks like is generated it self, here is the strange path in the source file:

(Resource id #33< ul >< li >< a href="#">< img src="img/test/.">< / a>< / li>< li>< a href="#" >< img src="img/test/..">< /a> )

The code continue normally as it should reading the images inside the folder after these two lines.

And here is the code i am using:

class HomeModel extends CI_Model{

public function getData(){

$dir = 'img/test';

echo opendir($dir);

if (is_dir($dir)) {

    if ($dh = opendir($dir)) {

     $display_models = '<ul>';

        while (($file = readdir($dh)) !== false) {

    $display_models .= '<li><a href="#"><img src="'.$dir.'/'.$file.'"></a></li>';

        }

    $display_models .= '</ul>';

        closedir($dh);

    }

      return $display_models;
}

}

}

Answer 1

hi add one if condition to check . and .. like this

while (($file = readdir($dh)) !== false) {
    if($file != '.' && $file != '..'){
        $display_models .= '<li><a href="#"><img src="'.$dir.'/'.$file.'"></a></li>';
     }

Answer 2

You doing this in model!

You need to do this on controller. Copy paste this in Controller and call the function, and you will get the correct result.

Models are PHP classes that are designed to work with information in your database. For example, let's say you use CodeIgniter to manage a blog. You might have a model class that contains functions to insert, update, and retrieve your blog data.
