You need to write a new action that performs the following in its execution function:
* Iterate over each selected node
* Find the file path(s) for each filefield
* Add the relevant path to a zip file using the PHP Zip API
* Set the PHP headers to the zip MIME type
* Write the zip file to the PHP output stream

I'm not sure I can get to this feature soon, so feel free to go ahead with an implementation. I'd be glad to help out.

Hi Karim,

I just got started with this. I have reached a stage where I have created an action that performs a task on each of the selected nodes. The problem is that we will need to have all the nodes going into the same zip file. Is there a way to identify the start and end of the action sequence that takes place? Please suggest if I am thinking on the right lines for what the action should do. The pseudo code is attached below:

action(){
if (is_first_call()){
create_archive();
}
add_file_to_archive();
if (is_last_call()){
close_archive();
}

I missed that point, sorry.

Take a look at this thread, that outlines how to create an aggregate action that accepts an array of nids for all selected nodes, instead of receiving node objects one by one. Your logic will then act just once and you can loop on all nodes.

This is a great feature request. It's one that I've been looking for, as well. The programming is probably over my head, but if I can help with testing in any way, feel free to let me know. I might be able to toss in somewhere around $100 as a bounty for this feature.

@scottrouse: I've been independently working on file download with VBO. The latest 6.x-1.x-dev release contains a new action called "Download archive of selected files". Note that this action only works for *File* views - please try it and give your feedback here. I am still thinking of how to design a similar action for *Node* view - your suggestions are welcome.

Also check out ImageField Archive for imagefields.

Hi,
I'm finding VBO very useful for my needs -- thank you for all the hard work! I'm also very keen to have bulk downloads of files. I tried installing 6.x-1.x-dev version to see how it works. After creating a File view and selecting the Bulk Operation style, I got the following errors:

warning: array_keys() [function.array-keys]: The first argument should be an array in /var/www/jobs.kemri/sites/all/modules/views_bulk_operations/views_bulk_operations_plugin_style.inc on line 222.

warning: in_array() [function.in-array]: Wrong datatype for second argument in /var/www/jobs.kemri/sites/all/modules/views_bulk_operations/views_bulk_operations_plugin_style.inc on line 173.

warning: in_array() [function.in-array]: Wrong datatype for second argument in /var/www/jobs.kemri/sites/all/modules/views_bulk_operations/views_bulk_operations_plugin_style.inc on line 93.

These errors display after I select "settings" for the Bulk Operations view style. In the settings panel, the list of "Selected operations" stops after the "Send e-mail (system_send_email_action)l" operation.

When using 6.x-1.9 version, I believe that my custom rule sets would normally appear directly after this operation, so I'm thinking maybe there's a formatting error or something in the call to custom rule sets?

Let's try not to do 20 things at the same time here.

VBO now has download support for "file" views, and infojunkie was kind enough to create ImageField Archive that does the same for nodes.
If the current VBO -dev (6.x-1.x-dev) has any bugs with this, please open a separate issue.
