HTTP POST requests in PHP

Question

How do you go about redirecting a browser and sending a HTTP POST request in PHP? A header("Location: file.php?foo=bar") of HTTP POST requests, if you will.

Answer 1

You can't - HTTP does not allow this - if you want to pass arguments via a redirect they have to be embedded into the URL as GET vars.

C.

Answer 2

This does not redirect the browser but it can perform a POST request.

To redirect the browser i'd suggest using Javascript.

An example form that does POST and redirect

 <FORM action="http://somesite.com/prog/adduser" method="post">
    <P>
    <LABEL for="firstname">First name: </LABEL>
              <INPUT type="text" id="firstname"><BR>
    <LABEL for="lastname">Last name: </LABEL>
              <INPUT type="text" id="lastname"><BR>
    <LABEL for="email">email: </LABEL>
              <INPUT type="text" id="email"><BR>
    <INPUT type="radio" name="sex" value="Male"> Male<BR>
    <INPUT type="radio" name="sex" value="Female"> Female<BR>
    <INPUT type="submit" value="Send"> <INPUT type="reset">
    </P>
 </FORM>
