POSTing to a PHP page

bonanza

Server: Apache 1.3.27
PHP 4.2.3
OS: Windows 2000
My expertise level: bonehead

I have two good PHP books, and I have spent much time searching the web for an answer, but I am finally resorting to asking for help.

PHP works fine, but I am still a bit confused as to how one POSTs to a PHP page. Should I be posting to a script (i.e. Perl) that produces a page, or can I refer to a PHP page directly (with it located either in HTDOCS or CGI-BIN. At the moment, neither works (I get a "The requested method POST is not allowed for the URL" message).

Any thoughts?

Well you could do it several ways

I generally self submit pages

<?php
// Hi I am your friendly PHP code
if ($_POST['Submit']) {
  // Someone has pressed the Submit button
  // Do the code for that crazy button presser
} else {
  // No one has pressed the Submit button
  // Escape out of php to html
?>
<form action="<?php $_SERVER['PHP_SELF']; ?>" method="POST">
[i] form code [/i]
<input type="Submit" name="Submit" value="Submit" />
</form>
<?php
// closing that if...else statement
}
?>

You can also have seperate the pages
and use functions like [man]headers[/man] to redirect the user.

Have fun
But if your using PHP 4.2.x make sure you use the superglobals $POST, $GET, ect.

hi!

when you write your submit form, the submit button has a variable name.

The script that receives the information (action field in the <form> tag) gets the entire $_POST array and that variable too...

the way i do it (like the previous post) is to check at the beginning of the script if the variable is set and act according to it: if the variable is set, then the script has data and can process it. if not, we need to show the form.

basically, your script will be divided by an if clause (for example) and only one part will be run, either the form part or the form-data-processing part.

hope it helped.
