    how to pass array of <input type='file'> with prototype.js

    hi to all

    I am unsing prototype.js for ajax. I am making a image/doc upload program. In which i am repeating the <input tpye='file'> option in a loop as desired by user. here's the code

    for($i=1; $i<=$max_no_img; $i++){
    <td>Document <?php echo $i ?></td>
    <td><input type="file" name="images[]" /></td>
    <?php } ?>

    Now i want to pass the values for these three files with the help of ajax but its not sending... the code is

    function upload_documents() {
    new Ajax.Request("upload_doc.php",
    method: 'post',

    postBody: '&images='+ $F('images'),
    onComplete: upload_documentsResponse

    function upload_documentsResponse(req){

    $('show_per').innerHTML= req.responseText;

    and further more i now have a requirement for only 3 uploads then i removed the loop, made 3 files input tag then den submitted with ajax.
    Now came another problem
    when i am echoing the files name with $_POST[] , it is printing the whole file name but when i am using

    $_FILES['images1']['name'] it not printing anyting I know tat $FILES is a multidimensional array so i even tried printing with foreach statement then too its not printing anything.

    Thanks in advance for any help........

    AFAIK a HTTP request by javascript cannot perform an upload. The actual form must be submitted and the browser's form handling must perform the upload.
    If you are learning PHP, developing PHP code, or debugging PHP code, do yourself a favor and check your web server log for errors and/or turn on full PHP error reporting in php.ini or in a .htaccess file to get PHP to help you.
