Build a catchstring to redirect pages
Posted on 2011-03-02
I have a site that has lost some pages. I am trying to catch the strings in old url from search engines and redirict them to the new replacement page. I am not sure if I am going the right direction with my code. And I have a provlem with url's that are a directory deep.
Here is what I am using:
I have 3 questions/issues:
1. Is this the best way to achieve this?
2. When there is a sub-folder (www.domain.com/articles/this-is-the-file.php) the catch string has to be "articlesthis-is-the-file.
and
3. It doesn't show images bacause it is not in the proper folder level.
Here is what I am using:
function stripstuff( $string )
{
$string = str_replace ( '/', '', $string );
$string = split ( '[?]', $string );
strtolower(trim($string[0]));
return $string[0];
}
$theFile = $_SERVER["REQUEST_URI"];
if ($theFile == "/" || $theFile == "")
{
// If nothing redirect to home page
header('Location: index.php');
}
else
{
$theFile2 = stripstuff($theFile);
query database for matching string
if ($num_rows > '0')
{
while ($rowID = mysql_fetch_array($result))
{
$ArticleCkID = $rowID['ArticleID'];
}
}
else
{
header('Location: site-map.php');
}

Have you got this in a 404 handler script?
I think I would do it by having a table of relationships - old URL to new URL.

Thanks Ray,
Yes and Yes. That is exactly what I am doing.
The problem I am having is with the "/". When I remove it ($string = str_replace ( '/', '', $string );
) I am assuming the file to look for will be www.domain.com/file.php. It strips it to file.php. However if it is www.domain.com/folder/file.php it strips it to "folderfile.php". It then is looking for the images from the "www.domain.com/folder/" folder level and no images show.

OK, let me ask the obvious question... Why are you removing the directory separators? Why not just translate $_SERVER["REQUEST_URI"] directly?

$_SERVER["REQUEST_URI"] grabs everything after the .com. "/file.php" or "/folder/file.php".
function stripstuff( $string )
{
$string = str_replace ( '/', '', $string );
$string = split ( '[?]', $string );
strtolower(trim($string[0]));
return $string[0];
}
$theFile = $_SERVER["REQUEST_URI"];
if ($debug) { echo "URI = " . $_SERVER["REQUEST_URI"] . "<br />"; }
if ($theFile == "/" || $theFile == "")
Yes, exactly. It contains PHP_SELF plus the query string. Maybe I am not understanding how your site has been re-organized, but it would seem to me that you could use PHP_SELF or REQUEST_URI to perform a lookup of the new URL, then redirect. Here is the code for one of my catch-all 404 handlers. It lets you have both of these URLs wind up in the same place"
example.com/script
example.com/script.php
Not very sophisticated but it will work for these, too.
example.com/script/foo
example.com/script/foo.php
example.com/script
example.com/script.php
Not very sophisticated but it will work for these, too.
example.com/script/foo
example.com/script/foo.php
<?php // 404handler.php
error_reporting(E_ALL);
if (isset($_SERVER["REQUEST_URI"]))
{
// IF A PHP SCRIPT IS NOT FOUND GO TO THE HOME PAGE
if (preg_match('#\.php#i', $_SERVER["REQUEST_URI"]))
{
header('Location: /');
exit;
}
// IF A NON-PHP SCRIPT IS NOT FOUND, TRY IT WITH PHP
$arr = explode('?', $_SERVER["REQUEST_URI"]);
$arr[0] .= '.php';
$uri = implode('?', $arr);
header("Location: $uri");
exit;
}
// IF NO REQUEST URI
header('Location: /');
exit;

Thanks Ray, I will use some ot that code.
I still have one problem,
When grabbing the url, a folder in between makes it hard to do a search.
Example:
$_SERVER["REQUEST_URI"] for www.somain.com/foldername/filename.php returns "/foldername/filename.php"
How would I trim this to just "filename.php" so I can search to see if that page exists in my database?

You can use basename()
http://us2.php.net/manual/en/function.basename.php
But you might consider the design pattern of something like this:
www.domain.com/tom/index.php
www.domain.com/ray/index.php
Tom and Ray might not have exactly the same index.php -- just a thought.

What I have is a site that was shut down for about a week. I can look up on google and view the cached pages. Problem is they are shtml. So I am building a catchstring script. I view the cached page, build a new page. Some pages are in the main directory and some are in sub directories. I am trying to strip the subdirectiory then redirect to a page created from the cache.
Does that help to make sense?
