Can PHP Post without a form?

[Larry L [in Honolulu]]

I have a dropdown list dynamically created in a form by PHP from a MySql
table. This is the only element on the page. For some records there is only
a single selection, and if that's the case I'd like to just post that and
go to the next page. Is there a simple way to do that using POST? I know
how to do it with GET, but don't like the resulting URLs.

Or is there a simpler method I'm not thinking about?

Thanks,
Larry

Yes, but it's got nothing to do with PHP:

<form method="POST" action="[your_action_goe s_here]">
<select name="mySelect" id="mySelect"
onChange="mySel ect.form.submit ()">
<option value="">Select an option
<option value="1">Optio n 1
<option value="2">Optio n 2
<option value="3">Optio n 3
<option value="4">Optio n 4
</select>
</form>

Well thanks, but maybe I didn't explain it well enough. I have pretty
much exactly what you show, but sometimes when the page loads, and the
options list is created, there is only one item there. If that's the
case, then I don't want to even show it, I just want the one option
posted to the next page.

In short: What kind of informations do you want to post to the next
page?

A bit longer: Sending a form to the client, just to have it posted back
immediately is not only really ugly, but also highly unreliable, since
it requires JavaScript. Dependent on the informations that have to be
sent around, there might be better ways (e.g. a server-side redirect,
sessions, CURL, ...)

PHP Manual example:
<?php
$link = mysql_connect(" localhost", "mysql_user ", "mysql_password ");
mysql_select_db ("database", $link);

$result = mysql_query("SE LECT * FROM table1", $link);
$num_rows = mysql_num_rows( $result);

echo "$num_rows Rows\n";
?>

instead of echoing the number you would use
if( $num_rows == 1 )
header("locatio n: pag2.php");

This is provided you haven't sent any information to the browser
already.

header("Locatio n: http://{$_SERVER['HTTP_HOST']}/pag2.php");

The URL must be absolute.

If you really need to post the forum, check CURL.

OTOH, I might recommend you store the appropriate info in a session, and
change the target page to look for the data in the session, also.

Thanks Jerry, ultimately that's what I did, it took me a while to realize I
already had a session open which made it pretty easy.
