Noob question regarding hooks

[sully02]

I'm looking at the files and I see the hook(s) inside. However, I don't want to add code, I want to change what the code directly above the hook does (Which is an if/else statement).

I'm going to assume this is possible to do using hooks. If so, how would I go about doing that? If not, I'm guessing it means I'd have to hack the code directly, right ?

Well it really depends on how the hook is placed, and what exactly is above the hook.

Fair enough. Here's what I'm looking at:

Above the hook...

PHP Code:

    // get date:
    if ($_REQUEST['do'] == 'getnew' AND $vbulletin->userinfo['lastvisit'] != 0)
    {
        // if action = getnew and last visit date is set
        $datecut = $vbulletin->userinfo['lastvisit'];
    }
    else
    {
        $_REQUEST['do'] = 'getdaily';
        if ($vbulletin->GPC['days'] < 1)
        {
            $vbulletin->GPC['days'] = 1;
        }
        $datecut = TIMENOW - (24 * 60 * 60 * $vbulletin->GPC['days']);
    } 


The hook (Right after the above code)...

PHP Code:

($hook = vBulletinHook::fetch_hook('search_getnew_start')) ? eval($hook) : false; 


What I'd like to replace the first block of code with...

PHP Code:

// get date: 
     if ($_REQUEST['do'] == 'getnew' AND $bbuserinfo['lastvisit'] != 0) 
     { 
          // if action = getnew and last visit date is set 
          $datecut = $bbuserinfo['lastvisit']; 
     } 
    else
    {
        $_REQUEST['do'] = 'getdaily';
        if (($days < 1)AND(!$hours)AND(!$minutes)AND(!$seconds))
        {
            $days = 1;
                        $hours = 0;
                         $minutes = 0;
                         $seconds = 0;
            
        }
        elseif($days < 1) {
                       $days = 0;
                }
        $datecut = TIMENOW - (($days*24*60*60) + ($hours*60*60) + ($minutes*60) + $seconds);
        
    }

The code you've pasted wont work since $days isnt set.

However, its easy to achieve using a hook by overwriting the variable instead of modifying the code.
