problems with POST
Hi,
The script below *used* to work. I have only just set up a server, PHP etc again on my Win98 system and now it doesn't? On first loading this page, you would have $p = and the button image below it. On clicking the button the same page would reload but pass the hidden values (r=w & p=f) so that the first line of the page would then have $p = f This no longer works??? <?php echo "<html><body>"; echo "\$p = $p<br><br>"; //### $str = <<<HTM <head> </head> <body> <form action="" method="post"> <input type="hidden" name="r" value="w"> <input type="hidden" name="p" value="f"> <input type="image" src="http://home/images/faq-up.gif" border="0" height="22" width="77"> </form> </body> </html> HTM; echo $str; ?> on printing the $_ENV variables along with the the above script I find the following : QUERY_METHOD POST REQUEST_METHOD POST FORM_P f FORM_R w Is there something I haven't enabled in my setup of PHP that is stopping this from working now? Or has something changed with PHP, so that I have to do this another way? many thanks mori

(Also see $_GET for variables passed by the GET method). Fix your script. Do not turn on "register_globals". Gordon L.

Re: problems with POST

tried changing the echo "\$p = $p<br><br>"; to echo "\$p = " . $_POST['p'] . "<br><br>"; but still not working :( mori "Gordon Burditt" <gordonb.ari4j@burditt.org> wrote in message news:11ok7r8qgjmg89a@corp.supernews.com... > >The script below *used* to work.

Re: problems with POST
Don't know much about PHP, but it does appear you are sending "<body>"
twice, once in line 2 and once in line 7. The one in line 2 should be deleted so the "<head>" section of the page comes first. Or you need to rearrange the order of your statements.

However, this makes absolutely no difference to the operation of the script.

If a simple HTML - Button is enougth try the simple Submit Button like in my example. Have Fun... <?php echo "<html>"; echo "\$p = ".$_POST['p']."<br><br>"; //### $str = <<<HTM <head> </head> <body> <form action="" method="post"> <input type="hidden" name="r" value="w"> <input type="hidden" name="p" value="f"> <input type="submit"> </form> </body> </html> HTM; echo $str; ?>
