Everyone i am looking for a way to automatically upload a file but skip the browse and choose file process.

So i set the location of the file somehow via the form and the client just has to click submit and it will automatcially upload the file from the path i have set. skipping the browse for file process.

I would like to intergrate it into the following undesigns S3 Class

http://undesigned.org.za/2007/10/22/amazon-s3-php-class/documentation

<?php

    S3::setAuth(awsAccessKey, awsSecretKey);

    $bucket = "upload-bucket";
    $path = "myfiles/"; // Can be empty ""

    $lifetime = 3600; // Period for which the parameters are valid
    $maxFileSize = (1024 * 1024 * 50); // 50 MB

    $metaHeaders = array("uid" => 123);
    $requestHeaders = array(
        "Content-Type" => "application/octet-stream",
        "Content-Disposition" => 'attachment; filename=${filename}'
    );

    $params = S3::getHttpUploadPostParams(
        $bucket,
        $path,
        S3::ACL_PUBLIC_READ,
        $lifetime,
        $maxFileSize,
        201, // Or a URL to redirect to on success
        $metaHeaders,
        $requestHeaders,
        false // False since we're not using flash
    );

    $uploadURL = "https://{$bucket}.s3.amazonaws.com/";

<?php
    foreach ($params as $p => $v)
        echo "        <input type=\"hidden\" name=\"{$p}\" value=\"{$v}\" />\n";
?>
        <input type="file" name="file" />&#160;<input type="submit" value="Upload" />
    </form>
</body>
</html>

at what point does it grab the file path ?

is it grabbing it out of the name here

can i do something with $_FILES ???

Can someone please give me a point on where to start i would really appriciate this.

thanks

You'll have to specify the tools of the trade. A common html form has no such functionality.

You can try value="c:\somefile.ext" but many browsers will not accept this.
