Using HTML Form Input Type File?

Question

I have a HTML form as follows:

<form action="/AddFile" method="post">
    <input type="file" name="filedata"/>
    <input type="submit" value="Add File"/>
</form>

When I use it and submit a file called foo with content bar the POST request contains filedata=foo not filedata=bar as expected.

What am I doing wrong? How do I get the content of the file?

One you need to add enctype="multipart/form-data" to the form.

Two you need to get the files from $_FILES instead.

Three I think it's file_get_contents($_FILES['filedata']['tmp_name']); to get the file's contents.

Your markup lacks the attribute enctype="multipart/form-data", which is needed when a file field is present. See HTML 4.01 spec on form element.

Using multipart/form-data, the file contents get sent. The rest depends on your server-side handler.
