old question (perhaps): redirect with POST of data?

[Alex Hunsley]

A question that has certainly been asked before and I've googled etc.
for answers with no certain outcome...

I'd like my PHP script to redirect the client browser to another page,
POSTing some data at the same time. (To take them back to an html page
showing a form that needs correcting because some data is missing.)
I believe this is either tricky or not possible from what I've seen, but
I'd just like to see what others think currently...

It's a little annoying because plain redirecting is easy and plain POST
to a URL (and get the results back) is easy too, but combining them
seems to be another matter...

thanks!

use a combination of sessions, post and get.

If you want the source code limited to one file then pass parameters on
the $_GET parameter list. If you use sessions then pass some of the info
via session variables, also use $_POST forms, all sorts of ways, depends
what works for your requirements

the $_GET parameter list.

I want to avoid just using a GET style URL as it looks unprofessional.

What exactly do you mean by $_POST forms?

thanks

He means from html:
<from action="bla.php" METHOD="POST">
<input type="text" name="color">
</form>

And from php:
$color = $_POST["color"];

Good luck.

Not going to work. If your page sends out a POST request, it
must receive response. You can show that response to the client,
but you may have broken links in it.

There is an alternative, however. If both pages are on the same
server, you can write POST data into session variables and then
redirect without arguments and have the second page retrieve data
from those session variables.

The following will redirect a POST request.

header("HTTP/1.0 307 Temporary Redirect");
header("Location: $url");

Works the last time I check in IE.

Yeah, I was ruminating on this earlier on and it is a good point!
I may just receive the resulting HTML (from my post operation) and just
shove that out to the browser.

server, you can write POST data into session variables and then
redirect without arguments and have the second page retrieve data

Ah, thanks for that clarification, I think one of the other repliers was
hinting at this but they were very vague about it... Cheers,

I may well be able to do it this way... thanks for the tip!

Was Flavell's "Redirect in response to POST transaction"[1] one of
those results?

Even though a 307 response is probably your best bet, it still doesn't
exactly guarantee success (at least in a Web context). Storing the
data between requests, or perhaps using cURL or sockets to perform the
second POST request and return the result, might be better. I haven't
tried either, though.

Anytime.
If you are someday in doubt what you mean, just ask me.

Yup, I did find that one.

Yeah, the article seems to say that results are a little unpredictable
and I don't think it would be as reliable as I want...
thanks!
