Question

I am using the following loop to send/attach multiple attachments to my email message.

foreach(array_keys($_FILES['attachment']['name']) as $key) {
    $source = $_FILES['attachment']['tmp_name'][$key]; 
    $filename = $_FILES['attachment']['name'][$key]; // original filename from the client
    $mail->AddAttachment($source, $filename);
}

But only the first attachment i made is sended.

The form code is

<form method="POST" action="<?php $PHP_SELF ?>"  enctype="multipart/form-data">
<input type="file" name="attachment[]" id="attachment" size="30"
onchange="document.getElementById('moreUploadsLink').style.display = 'block';" />
<div id="moreUploads"></div>
<div id="moreUploadsLink" style="display:none;">
<a href="javascript:addFileInput();">Attach another File</a></div>
<input name="submit" type="submit" value="submit" />
</form>

When one click on Attach another file, another File Upload button is shown, through a JavaScript function:

<script type="text/javascript">
var upload_number = 1;
var attachmentlimit = 5;
function addFileInput() {
    var d = document.createElement("div");
    var file = document.createElement("input");
    file.setAttribute("type", "file");
    file.setAttribute("name", "attachment"+upload_number);
    d.appendChild(file);
    document.getElementById("moreUploads").appendChild(d);
    upload_number++;
    if(upload_number == attachmentlimit) {
          document.getElementById('moreUploadsLink').style.display='none';
    }
}
</script>

Only the file attached through the first FileUpload Button is attached and sended, not the others.
Help.

The problem is that you are setting the name attribute of your new input element to attachment1, attachment2, etc. You should be setting this name to attachment[], just like the original input you created.

If you still don’t get all your attachments, you can try a var_dump($_FILES) in your PHP script to ensure that you are getting all the files the way you expect them.
