This nifty little addon will display "down" next to a link title if it is not working.

Credit goes to Slynderdale, he did all the hard work.

So, open links.php and find:

PHP Code:

require("./global.php"); 


Replace it with:

PHP Code:

require("./global.php");

    if (!$urlArray[path]) $urlArray[path] = "/";
    $sock = @fsockopen($urlArray[host], $urlArray[port], &$errnum, &$errstr, 10);
    if (!$sock) {
      $return[code] = "Dead";
    } else {
        $dump .= "HEAD $urlArray[path] HTTP/1.1\r\n";

        flush();
    }
    $return[status] = $status_array[$return[code]];
    return $return;
}
// End URL Status Checker 


Still in links.php, find:

PHP Code:

    $link[title]=stripslashes($link[title]);
    $link[date]=vbdate("m-d-Y",$link[dateline]);
    $link[time]=vbdate("h:i A",$link[dateline]); 


After this, add:

PHP Code:

    $linkstatus=check_url($link[url]);
    if ($linkstatus[code]!="200") {
      $link[status]="<highlight><i>(down)</i></highlight>";
    } else {
      $link[status]="";
    } 


Now save and upload links.php. For the next step go into your admin cp and edit template "links_listbit". Find:

PHP Code:

$link[title]</a></normalfont><br> 


Replace it with:

PHP Code:

$link[title]</a></normalfont> <smallfont>&nbsp;$link[status]</smallfont><br> 


Voila! If you want to test it, just enter a fictitious link with an obviously defunct URL. The word "down" should appear next to the link.

This may not work with some server configurations. If it doesn't, contact your web hosting company.
