PHP_SELF from an included file

[landsyaccount]

Hello.

I currently have a problem with $_SERVER["PHP_SELF"] when called from within an included file:

I have a several files included in one script, here are some snips of those files:

head.php

include( "./functions.php" );
include( "./constants.php" );

switch( $action ){
case "add":
$file = "addclient.php";
break;
case "view":
$file = "viewclient.php";
break;
default:
$file = "cust_main.php";

}

---

cust_main.php

<form action="<? $SERVER["PHP_SELF"] ?>">
<input type="hidden" name="action" value="add">
....
</form>
<form action="<? $SERVER["PHP_SELF"] ?>">
<input type="hidden" name="action" value="view">
....
</form>

---

index.php
include( "./head.php" );

<table>
<tr><td><? include( "./top.php" ); ?></td></tr>
<tr><td><? include( $file ); ?></td></tr> <!-- this file will dynamically change -->
<tr><td><? include( "./bot.php" ); ?></td></tr>

</table>

The first time the script runs the default file loads fine but, when the submit button is pressed to send all the information to the server it seems that the head.php file doesn't get parsed or called only the file where the PHP_SELF was called. the variable $action never get changed. How can I work around this?

Thanks in advanced for your help.

The only thing I can guess is that you go to "/index.php" and expect after hitting submit to go to "/index.php?action=something". If that's true, then you have two options:

1. Declare a variable before you include your custom file that has the $SERVER['PHP_SELF'] variable stored to it. Then instead of using $SERVER['PHP_SELF'] in the included files, use that variable.

2. Dynamically generate the URL that the form will post to. Since it will always be $SERVER['PHP_SELF'], that's relatively equivalent to using: http://$SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']

3. Leave the action of the form blank. By default it will send data back to itself, thus giving you what you want.

Those are listed in no particular order; however, #3 should really be avoided if at all possible. I'm not 100&#37; sure it's valid, and it's always better to be specific rather than vague 😉
