Save local copy of images from a URL

[brandonc]

This mod allows you to save a local copy of an image when loading the image from a URL path.  It downloads the file to the server and saves a copy of it on the server, instead of just referencing the URL.  I've found this incredibly useful and hope that you will too.  This also auto-creates thumbnails for me (using ImageMagick), but some other features may not work correctly as I didn't pay much attention to other functionality requirements.

Use the attached files to replace these files:

member.txt	->	4images_root/member.php
upload.txt	->	4images_root/includes/upload.php
member_uploadform.txt	->	4images_root/templates/4blue_orange1/member_uploadform.html

Of course the changes in the template file would need to be applied to which ever template you are using.  Just add this line in your template file where you want the option to appear:

Code: [Select]

<input type="checkbox" name="remote_media_file_download">Save a copy locally  <br />
Enjoy!

[newlooks]

is there any way to do multi upload  for URL

[maineyak]

I know this is an old post, but does anyone know why this is uploading the image twice?

[maineyak]

This is an awesome mod I installed with no problems. THanks!

[XFuzon]

I'm not getting any checkbox 

[maineyak]

I made mine a hidden field so it's automatically checked.

<input type="hidden" name="remote_media_file_download" value=checked>

[NetRebel]

Sounds like a great mod. Unfortunately it results in a

Fatal error: Call to undefined method Upload::save_downloaded_file() in /home/netrebel/public_html/files.netrebel.net/includes/upload.php on line 306

I can't find the save_downloaded_file() anywhere else in the code, so I tried changing it to move_downloaded_file but that didn't work either. How come maineyak writes it is working okay. Did I miss something?

[V@no]

add
  function save_downloaded_file($tmp_file) {
    global $user_info;

    $this->upload_file = $tmp_file;
    $ok = 1;
    if (empty($this->upload_file) || $this->upload_file == "none") {
      $this->set_error($this->lang['no_image_file']);
      $ok = 0;
    }


    if ($user_info['user_level'] != ADMIN) {
      if (!$this->check_max_filesize()) {
        $this->set_error($this->lang['invalid_file_size']);
        $ok = 0;
      }
      if (eregi("image", $this->HTTP_POST_FILES[$this->field_name]['type'])) {
        if (!$this->check_image_size()) {
          $ok = 0;
        }
      }
    }

    if (!$this->check_file_extension() || !$this->check_mime_type()) {
      $this->set_error($this->lang['invalid_file_type']. " (".$this->extension.", ".$this->mime_type.")");
      $ok = 0;
    }
    if ($ok) {
      if (!$this->copy_file()) {
        if (isset($this->lang['file_copy_error'])) {
          $this->set_error($this->lang['file_copy_error']);
        }
        $ok = 0;
      }
    }
    return $ok;
  }


above
  function download_file($field_name, $image_type, $cat_id = 0, $file_name = "") 

[NetRebel]

Yes, it's working great now!
Thanks a lot for your help V@no, and thanks brandonc for the original mod of course!
