Search options (Page 1 of 3)

The demo is not available so I couldn't give it a try. From a look into the source code, it seems to only provide the ability to run multiple forums on the same domain. The idea is a single installation that is accessible from any domain hosted on a server.

Thanks folks. The rate of these registrations is picking up, 7 today. Does Admin > Bans apply to new registrations or currently registered members only?

Ah, found it... Admin > Permissions, 'Allow banned email addresses'.

Small correction on the Admin > Bans page (actually the supplemental page). The help text says 'See "Allow banned e-mail addresses" in Options for more info.' But 'Allow banned email addresses' is on the Permissions page, not Options.

I can confirm that it now works correctly for both - and + timezones (I changed my system TZ to check). Also, it works with IE6 as well as Firefox 1.5 (on Windows 2000).

Very nice work Nibbler, thanks.

ps. Maybe you should update the linked js file (in your first post)?

Just a FYI... site5.com runs PHP as CGI (phpsuexec) on their servers. Which means that you can chmod 600 all your PHP files (especially config files) and you're neighbours can't access them.

Well like I said, fortunately I don't have that problem. I have one instance of 'same username / different email'. Once username was registered over a year ago with 0 posts, so I deleted it, thereby avoiding the issue. I suppose if I had to deal with it I would: (a) rename the instance of the username that was registered secondly, (b) adjust topics and posts accordingly, and (c) notify the user, perhaps gving him/her an ooportunity to select a new username.

Any idea why I get the message, "Bad request. The link you followed is incorrect or outdated" when I click on an imported topic, even though (a) the topic id exists in the database, and (b) the posts for the topic exist in the database, with the correct topic_id? This happens for all imported topic.

One thing I'd add is... work hard at keeping your programming separate from your HTML layout and design. It makes it much easier to maintain/update both. For example if you want to re-design the layout of a page, it's a PITA if the HTML is scattered all over the place amidst programming code.

The email address is also munged on the mail composition form. Also there is a 30-second flood control, and the same message cannot be sent twice.

Added Blog navigation and introduced the Guestbook feature over the past few days.

Boys will be boys as my dear old mom used to say :)

Someone just changed the value for page width, etc. to rediculously large absolute values (e.g. 7200 pixels).

In normal use a site administrator wouldn't hack his/her own site like that, at least not intentionally. Regardless, some sanity checking is required for page width, sidebar width and photo sizes.

I've worked up this to implement tonight or tomorrow:

// Check a value submitted from the Site Settings form:
function checkValue($string,$max_abs,$min_abs,$max_rel,$min_rel,$value) {
    // If the last char of submitted string is '%' we note it then remove it:
    if (substr($string, -1) == "%") {
        $rel=TRUE;
        $string = substr($string, 0, -1);
    }
    // Remove any non-numerial chars from the string:
    $length = strlen($string);
    $charnum = 0;
    $badchars = array();
    while ($charnum < $length) {
        $char = substr($string, $charnum, 1);
        if (!preg_match("/[0-9]/", $char)) {
            array_push($badchars, $char);
        }
        $charnum++;
    }
    foreach ($badchars as $bad) {
        $string = str_replace($bad,"",$string);
    }
    if (!$string) {
        $string = "0";
    }
    // Check that the value falls within the set range for relative (%) values.
    // If not, reset it and produce a warning message:
    if ($rel) {
        if ($string > $max_rel) {
            $new_string = $max_rel;
            $msg = "You specified $string% for $value. 
            The maximum allowed value is $max_rel%.";
        }
        elseif ($string < $min_rel) {
            $new_string = $min_rel;
            $msg = "You specified $string% for $value. 
            The minimum allowed value is $min_rel%.";
        }
        else {
            $new_string = $string;
        }
        $new_string = $new_string . "%";
    }
    // Or check that it falls within the set range for absolute (pixel) values.
    // If not, reset it and produce a warning message:
    else {
        if ($string > $max_abs) {
            $new_string = $max_abs;
            $msg = "You specified $string pixels for $value. 
            The maximum allowed value is $max_abs pixels.";
        }
        elseif ($string < $min_abs) {
            $new_string = $min_abs;
            $msg = "You specified $string pixels for $value. 
            The minimum allowed value is $min_abs pixels.";
        }
        else {
            $new_string = string;
        }
    }
    return array($string,$new_string,$msg);
}

If a $msg is generated, the user will be sent back to the site setting form after submitting. The msg (in red) will be inserted below the input field for the particular value, and the value in the input field willl be reset to the $new_string (sanitized) value.

If anyone has comments, suggestions they're always welcome.
