drop down menu using php

[johnsponheimer]

I am trying to make a drop down menu using php...

Basically something like this.

A Drop down menu with 10 items (you can only pick 1 item)
Then you hit GO.

All it should do would forward you onto that page.

Basically its going to be a huge menu, in which a user can goto any of the 10 webpages programmed into the small script.

Simple enough I know, but then I am so new to programming its "beyond me".

Can anyone give me any assistance?

The HTML menu might look like this:

<form action="<?php echo $PHP_SELF; ?>" method="post">
<select name="pagename">
<option value="thispage.php">This Page</option>
<option value="thatpage.php">That Page</option>
<option value="anotherpage.php">Another Page</option>
</select>
<input type="submit" name="button" value="Go">
</form>

The PHP might look like this:

// Check to see if a page was selected *before* generating any content, since we're sending a header():
if(isset($HTTP_POST_VARS['pagename'])) {
	// Redirect to that page:
	header('Location: ' . $HTTP_POST_VARS['pagename']);
}

Try it. It might just work...

Of course if you are using a PHP 4.1.0 or above, you could use $_POST instead of $HTTP_POST_VARS for your form variables.

I have this....

form action="<?php echo $PHP_SELF; ?>" method="post">
<select name="pagename">
<option value="http://www.blah.com/index.php">Page 1</option>
<option value="http://www.blah.com/index2.php">Page 2</option>
</select>
<input type="submit" name="button" value="Go">
</form>

I select one of them, and hit go and the page just refreshes....
?

Try this ... it worked for me.

<?php

if ( isset($_POST[pagename]) ) {
	header("Location: $_POST[pagename]");
} else {
?>
	<form action="<?php $_SERVER[PHP_SELF]; ?>" method="post"> 
	<select name="pagename"> 
	<option value="thispage.php">This Page</option> 
	<option value="thatpage.php">That Page</option> 
	<option value="anotherpage.php">Another Page</option> 
	</select> 
	<input type="submit" name="button" value="Go"> 
	</form>
<?
}

?>

Gosh, I just tested it using php files which I know exist on my development server and it worked just fine.

So, I stuck in a http://www.blah.com/index.php option in my select menu, and I got redirected to www.blah.com, with a 404 error message from an IIS webserver when I made that selection...

Conclusion? I'd bet you're doing something wrong... Post the PHP code you're using, just to make sure you copied what I posted...

[johnsponheimer]

First of all, I appreciate your assistance guys...
Here is the code I have used.

<?php
if_(_isset($_POST[pagename])_)_{
____header("Location:_$_POST[pagename]");
}_else_{
?>

<form action="<?php_$_SERVER[PHP_SELF];_?>" method="post">
<select name="pagename">
<option value="thispage.php">This Page</option>
<option value="thatpage.php">That Page</option>
</select>
<input type="submit" name="button" value="Go">
</form>

<?php
}
?>

I get this error...
Parse error: parse error, unexpected T_STRING in /home/completerpg.com/html/rpg/rpgindex1.php on line 32
which is this line

if_(_isset($_POST[pagename])_)_{

Uh, be careful with those underscores...

BTW, if you're using PHP > 4.1.0 the $HTTP_POST_VARS array is still available, though deprecated.

johnsponheimer,

My guess is that your problem is with whatever the rest of the code in your script is, because standing-alone, this snippet of code of the pop-down menu works fine.

[johnsponheimer]

Strange....
very strange...

Does the above script point to files in the same directory?
Or can it point to files with a FQDN --> http://www.blah.com/dir1/dir2/blah.php ??
