Question

I done delete image url from database with following code, but is not delete file image from upload path, how can delete file from upload path with url it in database (both together)?

This php is just for delete url from database:

$delete = $this -> input -> post('checked');
foreach($delete as $val) {
    $this - > db - > delete($this - > _table, array('id' = > $val));
}

Update:

I have error in use of following code.

$id = '166';
$query = $this - > db - > get_where('hotel_image', array('id' = > $id));
if ($query - > num_rows() > 0) {
    $res = $query - > row();
    unlink(base_url(uploads/$res - > images));//This is line 161
}
$this - > db - > delete('hotel_image', array('id' = > $id));

Error:(my images are in this pach: http://example.com/uploads/)

You need to use unlink() to delete a file from disk, just pass the filename as parameter.

bool unlink ( string $filename [, resource $context ] )

Deletes filename. Similar to the Unix C unlink() function. A E_WARNING
level error will be generated on failure.

Something like (this is simplified code. You might want to check the path from DB is complete or else add the rest.):

$delete = $this -> input -> post('checked');
foreach($delete as $val) {
    $this->db->select('images')->from($this->_table)->where('id',$val);
    $query = $this->db->get();
    if($query->num_rows() > 0)
    {
      $res = $query->row();
      $file = './uploads/'.$res - > images));
      // echo $file;  #check if this is the correct path!
      @unlink($file);
    }
    //now query to delete
    $this -> db -> delete($this - > _table, array('id' = > $val));
}
