Php Redirect? Or load a new page?

[Nonee]

Hello all-

I have a php page that has a form box in it. With that form box, I
check and see if the value in the form + ".php" is a file that exists.
(No probs so far) Then if it does exist, I want to redirect the
browser to go there. I know there is a header("location: $filename");
that could work but it doesn't. What am I missing and how can I do
this?

Thanks VERY much... (Been racking my brain and the net all day)

Presumably you've already added .php to the filename.

header("location: ".$filename);

At the moment you're trying to send them to a file called "$filename",
which obviously doesn't exist. Short answer: don't quote the variable
name.

Can you post a *short* sample of code that shows how you're handling
extracting the value from the form, and then how you're using the
header() statement?

NOTE: this would be better off in a PHP NG...

Actually, in PHP, that's fine. With double-quoted strings, PHP performs
in-line variable substitution.

No idea why, other then perhaps your browser being picky and insisting on an
absolute URL (as required by the HTTP spec) rather then the relative one
you are giving it. Most browsers are pretty good at error recovery along
those line though.

I'd probably start constructing HTTP requests by hand with a telnet client
to see exactly what was being sent back and forth.

All that but the address must be absolute. See the php manual

Something like this perhaps

("Location: http://" .$_SERVER['HTTP_HOST']. "/" . $filename);

Err ... I said that.

<?php
if (empty($_POST["name"]))
{
}
else
{
$name=$_POST["name"];
$filename = $name."/index.php";
if (file_exists($filename))
{
echo "The file $filename does exist";
header("Location:
http://".$_SERVER['HTTP_HOST']."/".$filename);
}
else
{
echo "The file $filename does not exist";
}
}
?>

That is the code and it is still not working... Not sure as to why
though. Remember, someone types in a name in a form textbox and posts
it to the same php file. From the submit post, it posts the textbox
("name") and I retrieve it from the $_Post. Etc etc etc. The rest is
pretty self-explainitory. Any other ideas?

Thanks!!!


P.S. Btw, the $name."/index.php" points to a subdirectory using the
$name as the subdirectory. Confused? lol...

{
$name=$_POST["name"];
$filename = $name."/index.php";
if (file_exists($filename))
{
echo "The file $filename does exist Location:
http://".$_SERVER['HTTP_HOST']."/".$filename;
header("Location:
http://".$_SERVER['HTTP_HOST']."/".$filename);
}
else
{
echo "The file $filename does not exist";
}
}
?>

Ok, an update. The new location is pointing to the right directory
but it is still not loading the new page. In addition, it is finding
the file. It just will NOT relocate to the new location. Grrr....

Do you have errors reported?

You did. Apologies David.

header("location: ".$filename);

header("location: $filename") and header("location: ".$filename) are
exactly identical statements.

My two suggestions are:

1. When using your file_exists function, try using the full path from the
computer's root directory (which is probably different from the Apache
ServerRoot, unless you want to get rooted).

2. Make sure you're putting the header() statement before your PHP has
outputted any other data to the browser (including blank lines).

 

[Toby Inkster]

header("location: ".$filename);

PS: instead of "foo".$array[0] you can use "foo${array[0]}".

Hi there,
I tried to give you the solution on this message but for some odd reason all references to http are taken as links and I am not allowed to post links as I am a newcomer here. I am trying to attach it as a text file for you. Hope it work.
