Multiple images upload with ImageField via FTP

This snippet allows multiple images upload with ImageField module via FTP Client.
It uses CCK Computed Field to manage multiple files upload.

Configuration

We need to create a directory in file system and 4 CCK fields:

1. Create a folder (we call it ftp_gals) in sites > default > files where folders containing images will be stored.
2. Create a single on-off checkbox element (we call it field_reload_gallery) and set allowed values ("Import now" and "Don't import" should sound good).
3. Create a textfield element (field_new_gallery). You can call it Folder name.
4. Create a imagefield element (field_g_slideshow) and set number of values to unlimited.
5. Create a CCK Computed field and paste this code in Computed Code textarea:
   

   $boolean_check_on = "Import now";
   $boolean_check_off = "Don't import";
   // these are the two allowed values of the CCK single on-off checkbox element which user checks for starting import process
   
   $your_galleries_folder = "ftp_gals";
   // the folder under /sites/default/files which contains user's galleries folders
   
   if ($node->field_reload_gallery[0]['value'] == $boolean_check_on) {
   // field_reload_gallery is the CCK single on-off checkbox element which user check for starting importation
   
     $tg_gallery = file_directory_path() . "/". $your_galleries_folder . "/" . trim($node->field_new_gallery[0]['value']);
     // field_new_gallery is the CCK textfield element where user write gallery's folder name
   
     $node->field_reload_gallery[0]['value'] = $boolean_check_off;
     // setting off checkbox for any next node editing
   
     $imgs = file_scan_directory($tg_gallery, '.*');
     sort($imgs);
     $node->field_g_slideshow = array();
     // field_g_slideshow is the CCK imagefield element which will be populated with images data
     
     foreach ($imgs as $file_img) {
       $this_file_path = $file_img->filename;
       $ins_file = array(
         'list' => 1,
         'filename' => basename($this_file_path),
         'filepath' => $this_file_path,
         'filemime' => file_get_mimetype($this_file_path),
         'filesize' => filesize($this_file_path),
         'uid'      => 1,
         'status'   => 1,
         'timestamp'=> time()
       );
       drupal_write_record('files',$ins_file);
       $node->field_g_slideshow[] = (field_file_load($this_file_path));
     }
     // files information are now stored in database
     // uid = 1 is drupal superuser, you can change it
     
   }
   $node_field[0]['value'] = "";
   // return this field empty
   
   

6. Give FTP access to ftp_gals to the user.

How to upload multiple images:

1. Create a folder (gal1) containing images and upload it via FTP (in sites > default > files > ftp_gals). (You can use any FTP Client, as Filezilla, Duckload and so on)
2. Create a node and put folder name (gal1) in the appropriated textfield element (field_new_gallery).
3. Check the checkbox (field_reload_gallery).
4. Save the node!

Important

When user checks the box and save the node imagefield CCK element will be resetted before import.
