Update from 2.6 and Image routing

[LagunaPower]

Hello

I've just updated Cheverto 2.6 to the latest version. Problem is that in the old version I've had links like:

http://domain.tld/ID
and now it's
http://domain.tld/image/ID

And the /dashboard/settings/routing doesn't allow to just use the domain (empty field).

Can you please advise how to change /image to /?

Thank you in advance.

V2.X used ?v=name.jpg which is supported in V3. However, your /ID routing is custom made, you will need to manually route the old URLs to new ones.

I didn't modify anything!
this a screenshoot of the 2.6 you can see http://domain.tld/ID

Well, it has been years you know? V2 was deprecated several years ago (2014) and even I do have a hard time remembering how it works.

To be honest, I don't remember how I solved this issue from V2 to V3 and I can't figure out what you could do at this time.

Sorry.

thanks for your answer. I know it's very old very but it was corresponding for my use case.
The only problem now it's Flash...


So in wich php file the url is interceped and decoded?

I think write a function for rewrite the url if the decoded id match a image id in the images table.
What do you think about it?

Chevereto-Free routes /root to user at app/loader.php (paid edition does it somewhere else).

if ($base !== 'index' and !G\is_route_available($handler->request_array[0])) {

If you ask me, it is easier to just write down a server rule for each known ID. That way you won't stress php with the job of redirecting.

My job is admin system, not dev...

This is what I do :

function chv_decode_id($var) {
    $base_chars = "abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"; // DON'T REPEAT A SINGLE CHAR!
   
    for ($n = 0; $n<strlen($base_chars); $n++) {
        $i[] = substr( $base_chars,$n ,1);
    }
    $lochash = hash('sha256',"fsndbijbfvgsjdncjsd");
    $lochash = (strlen($lochash) < strlen($base_chars)) ? hash('sha512',"fsndbijbfvgsjdncjsd") : $lochash;

    for ($n=0; $n < strlen($base_chars); $n++) {
        $p[] =  substr($lochash, $n ,1);
    }

    array_multisort($p, SORT_DESC, $i);
    $base_chars = implode($i);
   
    $integer = 0;
    $var = strrev($var );
    $baselen = strlen( $base_chars );
    $inputlen = strlen( $var );
    for ($i = 0; $i < $inputlen; $i++) {
        $index = strpos($base_chars, $var[$i] );
        $integer = bcadd($integer, bcmul($index, bcpow($baselen, $i)));
    }
    return $integer;
}

$loc_base = "/new/";
$loc_lg_base = strlen($loc_base);
$i_last_id = 3493;
$loc_host = $_SERVER['HTTP_HOST'];
$Uri = $_SERVER['REQUEST_URI'];
$MaVariable = substr($Uri,0,$loc_lg_base);
$loc_proto = "http://";
$loc_coded_id = substr($Uri, $loc_lg_base);
$loc_img_route = "/image/";
if ( $_SERVER['HTTPS'] == "on" ) {
    $loc_proto = "https://";
}

if ($Uri != $loc_base) {
        if ( $MaVariable == $loc_base ) {
            (int) $loc_tstid = chv_decode_id( $loc_coded_id );
            if ( $loc_tstid < ($i_last_id + 1) ) {
                $loc_header = 'Location: ' . $loc_proto . $loc_host . $loc_base . $loc_img_route . $loc_coded_id;
                header( $loc_header );
                exit;
            }
        }
}

I had this code to /index.php (before the define).
