Question

What, precisely is submitted to the webserver in a file upload http request?

ie. If I have the following form,

<form action=%URL% method="POST" enctype="multipart/form-data">
     <input name="fileinfo" type="file" /><br />
     <input name="submit" type="submit">
</form>

What is the request that will be sent to the server?

Answer 1

will be something like below… just use print_r to see what is going into your script

echo "<pre>";
print_r($_GET);
print_r($_POST);
print_r($_FILES);

 [fileinfo] => Array
    (
        [name] => MyFile.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/php/php6hst32
        [error] => UPLOAD_ERR_OK
        [size] => 98174
    )
