I have a a PARENT file and a CHILD one (relation on the fieldid)

There is a blob field in each record of CHILD that ca contain mostly a doc or pdf or jpg file.

In the list page there is the possibility of downloading them ONE by ONE.

I would like to download all the files belonging to all the records of CHILD file.

Is there the possibility to do that?

Maybe using some code (?) in a separeted button?

THank you

You need custom code. You can create a zip file on the fly to collect the files belonging to all the records of CHILD file.

OK Thank you, I take a look to that link and I found it very interesting, and it is not a problem to retrieve the files name fron the DB.

But for the above problem, if I need to download 'EVERY' file (without making a ZIP ?

I'm not sure I understand what you mean. Post some screenshots of your app.

Domenico, the zip solution is the best way. Saving file on the client side requires a confirmation from the user.

Yes, Ok I understand, but it is the solution I would like to have:

ONE click to download all the files and one confirm for each file to download....

(The user MUST not have to UNZIP the files downloaded)

In the "Client after" trigger the click event for each file link using jquery. You have to check the exact path of the links in the DOM.

THank you.

I understand the first paart of your message, but I really no idea how ".... to check the exact path of the links in the DOM."
ANYWAY .... thank you to everybody.

I found the solution I would like to have by myself.

Here it is a solution. In the "Client after" tab of the button enter the following code:



var fileArray = new Array();

$('body').append('<iframe src="" id="download-list" style="display:none;" />');
$("td span[id $= '_yourfieldname'] a:first-child").each(function(){

fileArray.push($(this).attr('href'));

});
var i = 0;

var downloadList = $('#download-list');
downloadList.attr('src', fileArray[i]);

i++;
var interval = setInterval(function()

{

if(i < fileArray.length)

{

downloadList.attr('src', fileArray[i]);

i++;

}

else

{

clearInterval(interval);

}

}, 100);


Replace the _yourfieldname string with the real name of the field that stores file names.

For example if the field name is corpo_documento the jquery selector becomes:



$("td span[id $= '_corpo_documento'] a:first-child")
