[Resolved] redirect folder to dynamically generated url

Hamsterpants

Hi All,

I am busy setting up a site where one of the things a user can select is a user friendly url, eg. www.mysite.com/friendlyurl . Once they have completed, the url to their details (on a dynamic php page), would look something like this - link.php?id=1&cat_id=2&subcat_id=4 . Now is it possible to some how link the friendly url to that. I know I can edit the htaccess file, but I need a way that this is maintaned with a script so that at the time the link is created, the redirect is set up at the same time,

Any helpw ould be appreciated.

How about creating an index.php page and in it put the following:

<?php
header("Location: http://mysite.com/link.php?id=1&cat_id=2&subcat_id=4");
?>
<html>
<head>
<title></title>
</head>
<body>
Redirecting...</body>
</html>

This way you would use fopen() and chmod() to write and edit/protect the file. So in essence, it would look something like:

<?php
$dir = $_REQUEST['dir_name'];
$id = $_REQUEST['id'];
$cat = $_REQUEST['cat_id'];
$subcat = $_REQUEST['subcat_id'];
$link = 'id='.$id.'&cat_id='.$cat'.&subcat_id='.$subcat;

$content = '<?php'.
                'header("Location: http://mysite.com/link.php?'.$link.'");'.
                '?>'.
                '<html><head><title></title></head><body>'.
                'Redirecting...</body></html>';

$template = 'template.php';
$file_dir = $_SERVER['DOCUMENT_ROOT'].'/backup/';
$index = 'index.php';

mkdir($_SERVER['DOCUMENT_ROOT'].'/'.$dir);
copy($file, $index);
rename($file_dir.$index, $dir.$index);

if (!is_writable($dir.$index)) {
    if (!chmod($dir.$index, 0666)) {
          echo "Cannot change the mode of file (".$dir.$index.")";
          exit;
    };
}
if(!$fp = @fopen($dir.$index, "w")){
    echo "Can't open file (".$dir.$index.")";
    exit;
}
if(!fwrite($dir.$index, $content)){
    echo "Can't write to file.";
    exit;
}
if (!fclose($fp)) {
    echo "Cannot close file (".$dir.$index.")";
    exit;
}
?>

Hope I helped.

Hi Bret,

After realising that I wasn't going to be able to write to the .htaccess file with a php script, this is the sort of thing I was thinking about, but wasn't 100% sure how I was going to do it. You have just saved me hours of frustration. Thanks very much, what you have suggetsed and provided is perfect.

Once again
Thanks

Happy coding...

Hi Brett,

Hope you dont mind but I am useing the code that you provided in the post. I uoloaded and gave it a try, and received the following error. Creating files and chmod is very new stuff to me, and your code looks a little different to the eg I have seen before, so was hoping you could maybee offer some help on the followin error:

Cannot change the mode of file (newlinkindex.php)
I am confused here because, from the error looks like the script is trying to chmod the dir called dirandfilename, rather then just the dir, is that an error in the code?

Also just a quick question, with php, when scripts create files or dir, they are created as user "nobody" is that correct? In which case, will a script have the correct level to be able chmod files and dir?
Thanks

Hi Brett,

I used a solution provided by Roger in one of my earlier post which was to use the .htaccess file to redirect, but instead of using the one in the root, because php scripts cannot chmod because a php script when it runs, runs as user "nobody", and user "nobody" does not have the right permissions to chmod. I instead used php to create a folder and a htaccess file within that folder. That now meant that that folder and htaccess file belong to the group "nobody", I think. Well anyway, now I could chmod with a php script.

Anyway I thought I would just let you know, and once again thanks for the help.

Hey Dill.

I was just trying to help you out, and wasn't 100% sure that the code would work, although I had thought it would. CHMOD is new to me, but if you need to read more on it go here.

As far as the other questions you pose....

The way the the code is written I could be wrong.

Try this:

<?php
$dir = $_REQUEST['dir_name'];
$id = $_REQUEST['id'];
$cat = $_REQUEST['cat_id'];
$subcat = $_REQUEST['subcat_id'];

$link = 'id='.$id.'&cat_id='.$cat'.&subcat_id='.$subcat;

$content = '<?php'.
                'header("Location: [url]http://mysite.com/link.php?[/url]'.$link.'");'.
                '?>'.
                '<html><head><title></title></head><body>'.
                'Redirecting...</body></html>';

$root_dir = $_SERVER['DOCUMENT_ROOT'].'/';
$new_dir = $root_dir.$dir;

$old_file = $root_dir.'/backup/template.php';
$old_index = $root_dir.'/backup/index.php';
$new_file = $root_dir.$dir.'index.php';

mkdir($new_dir);
copy($old_file, $old_index);
rename($old_index, $new_file);

if (!is_writable($new_file)) {
    if(!chown($new_file, root)){
        echo "Cannot change user!!";
    };
    if (!chmod($dir.$index, 0666)) {
          echo "Cannot change the mode of file (".$dir.$index.")";
          exit;
    };
}
if(!$fp = @fopen($new_file, "w")){
    echo "Can't open file (".$dir.$index.")";
    exit;
}
if(!fwrite($new_file, $content)){
    echo "Can't write to file.";
    exit;
}
if (!fclose($fp)) {
    echo "Cannot close file (".$new_file.")";
    exit;
}
?>

Try that. I think the reason you got an error is because the php script wasn't working in the right folder. It's a possibility, but not promising anything.

Just reply if there are any problems.
