Multiple attachments from one field

I have also set the pdf field as a longblob to store the files in the database, but this only alows me to store 1 file per field, and I do have to store anywhere from 1 to 6 files in the same field, if not, I would have to set up 6 fileds to store files and most of the time I would upload 1 - 3 files and the rest of the fields would be blank, which, kind of confuses my users.
Oh, and I have already looked through the forum, but couldn't find anything to do this.
Thanks in advanced.

Look at this. It may help you access the files.

Thanks, I have gone through the link that you posted, but apparently I don't know how to use it, I've added this on the after record updated event and on the javascript onload event:
$fileArray = my_json_decode($values["pdf"]);

$values["pdfiles"] = my_json_encode($fileArray);
But nothing happens.
I've also added this on the after record updated event:
$fileArray = my_json_decode($values["pdf"]);
$data = array();

$keyvalues = array();

$data["pdfiles"] = $fileArray;

$keyvalues["id"] = $values["id"];

DB::Update("facturas", $data, $keyvalues );
And nothing, my DB doesn't get updated with the file names.
P.S. pdf = field where the files get uploaded (varchar2000)

pdfiles = field where the file names are supposed to be

You will need to loop through the values stored in that field ($values["pdf"]). I don't see you doing that in your code. There are examples in the link to access the files. I also don't see anything there for you to email as you stated in your original post. It is kind of confusing.
Here is a different link that shows how to access the files, attach and email.

Awesome, thanks, you where right, I was not looping through the values, here's the code I finally used:
$record = $button->getCurrentRecord();

$result["pdf"]=$record["pdf"];

$result["factura"]=$record["factura"];

$fileArray = my_json_decode($result["pdf"]);

$attachments = array();

foreach($fileArray as $f)

{

$attachments[] = array("path" => $f["name"]);

}
//email

$email_msg = "";

$email_msg.= "";

$email_msg.= " Good afternoon,\n";

$email_msg.= "\n";

$email_msg.= " Attached please find the required documents for the importation of --------.\n";

$email_msg.= "\n";

$email_msg.= " Attached are:\n";

$email_msg.= " a) Bill of Ladings.\n";

$email_msg.= " <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=reply&id=90445&image=1&table=forumreplies' class='bbc_emoticon' alt='B)' /> Invoices A11, A12 and A13.\n";

$email_msg.= " c) Certificate of Origin.\n";

$email_msg.= "\n";

$email_msg.= " As always, we appreciate your support.\n";

$email_msg.= "\n";

$email_msg.= " Best regards.\n";

$email_msg.= "\n";

$email_msg.= " RC..\n";
//send email

$email = "something@mail.com";

$subject = "Facturas: ".$result["factura"];

runner_mail(array('to' => $email, 'subject' => $subject, 'body' => $email_msg, 'attachments' => $attachments));
Now I have to gather the attachments from several fiels, the fields I have with files are: invoices, bol, and certorg, I have to grab the files from those fields to send them as an attachment, I'll let you guys know if I figured out and how I did it, of course, any and all help is appreciated.

BLAMO!!!! I SOLVED IT!!!
I used array_merge:
$record = $button->getCurrentRecord();

$result["pdf"]=$record["pdf"];

$result["factura"]=$record["factura"];

$result["xml"]=$record["xml"];
$fileArray = my_json_decode($result["pdf"]);

$attachments = array();

foreach($fileArray as $f)

{

$attachments[] = array("path" => $f["name"]);

}
$fileArray2 = my_json_decode($result["xml"]);

$attachments2 = array();

foreach($fileArray2 as $f2)

{

$attachments2[] = array("path" => $f2["name"]);

}
//email

$email_msg = "";

$email_msg.= "";

$email_msg.= " Good afternoon,\n";

$email_msg.= "\n";

$email_msg.= " Attached please find the required documents for the importation of .\n";

$email_msg.= "\n";

$email_msg.= " Attached are:\n";

$email_msg.= " a) Bill of Ladings.\n";

$email_msg.= " <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=reply&id=90446&image=1&table=forumreplies' class='bbc_emoticon' alt='B)' /> Invoices A11, A12 and A13.\n";

$email_msg.= " c) Certificate of Origin.\n";

$email_msg.= "\n";

$email_msg.= " As always, we appreciate your support.\n";

$email_msg.= "\n";

$email_msg.= " Best regards.\n";

$email_msg.= "\n";

$email_msg.= " RC.\n";
//send email

$email = "email@email.com";

$subject = "Facturas: ".$result["factura"];

runner_mail(array('to' => $email, 'subject' => $subject, 'body' => $email_msg, 'attachments' => array_merge($attachments, $attachments2)));
