Using indexpost() on non-vB Pages...

[DarkReaper]

I'm writing a news system that inserts news into vBulletin for comments, and am having trouble getting the posts to be indexed for searching. I'm not including any vB files, so I copied the indexpost() function over and had it switch databases to the forums DB to index it. However, it's not indexing the posts...

PHP Code:

// ###################### Start indexpost #######################
function indexpost($postid) {
  global $DB_site;
  $minsearchlength = 3;
  $maxsearchlength = 18;

  echo "val = $val<br>";


  $DB_site->select_db($forumdbname);


  $post=$DB_site->query_first("SELECT postid,threadid,title,pagetext FROM post WHERE postid='$postid'");


    $threadinfo=$DB_site->query_first("SELECT title FROM thread WHERE threadid=$post[threadid]");
    //$post[title].=" ".$threadinfo[title];

    // What is the point of this?///////
    $firstpst[$post[threadid]]=$postid;
    ////////////////////////////////////

    $titlewords=trim($threadinfo[title]);
    $titlewords=ereg_replace("[\n\t\r,]"," ",$titlewords);
     $titlewords=preg_replace("/(\.+)($| |\n|\t)/s", " ", $titlewords);
     $titlewords=str_replace("[", " [", $titlewords);
     $titlewords=str_replace("]", "] ", $titlewords);
     $titlewords=preg_replace("/[\(\)\"':;\[\]?!#{}_\-+\\\\]/s","",$titlewords);
     $titlewords=strtolower(trim(str_replace("  "," ",$titlewords)));
     $titlewordarray=explode(" ",$titlewords);
     while (list($key,$val)=each($titlewordarray)) {
         echo "val = $val<br>";
       $titlearray[$val]=1;
     }


  $allwords=$post[title]." ".$post[pagetext];
  $allwords=preg_replace("/[\n\t\r,]/s"," ",$allwords);
  $allwords=preg_replace("/(\.+)($| |\n|\t)/s", " ", $allwords);
  $allwords=str_replace("[", " [", $allwords);
  $allwords=str_replace("]", "] ", $allwords);
  $allwords=preg_replace("/[\(\)\"':;\[\]?!#{}_\-+\\\\]/s","",$allwords);
  $allwords=strtolower(trim(str_replace("  "," ",$allwords)));
  if ($titlewords)
    $allwords.=" ".$titlewords;
  $wordarray=explode(" ",$allwords);


  $getwordidsql="title IN ('".str_replace(" ","','",$allwords)."')";
  $words=$DB_site->query("SELECT wordid,title FROM word WHERE $getwordidsql");

  while ($word=$DB_site->fetch_array($words)) {
    $wordcache[$word[title]]=$word[wordid];
  }
  $DB_site->free_result($words);

  $insertsql="";
  $newwords="";

  echo "val = $val<br>";
  echo "worddone[val] = $worddone[$val]<br>";

    if ($val!=""  and !$worddone[$val]) {
      $worddone[$val]=1; // Ok we have added this word
      if (isset($wordcache[$val])) { // Does this word already exist in the word table?
        if (isset($titlearray[$val]))
          $intitle=1;
        else
          $intitle=0;
        $insertsql.=",($wordcache[$val],$postid,$intitle)"; // yes so just add a searchindex entry for this post/word
        echo "insertsql is now $insertsql<br>";
        flush();
      } else {
        if (isset($titlearray[$val]))
        {
          $newtitlewords.=$val." ";
          echo "Added $val to the title table<br>";
          flush();
        }
        else
        {
          $newwords.=$val." "; // No so add it to the word table
          echo "Added $val to the word table<br>";
          flush();
        }
      }
    }


  

  if ($insertsql!="") {
    $insertsql=substr($insertsql,1);
    $DB_site->query("REPLACE INTO searchindex (wordid,postid,intitle) VALUES $insertsql");
  }

  if ($newwords) {
    $newwords=trim($newwords);
    $insertwords="(NULL,'".str_replace(" ","'),(NULL,'",addslashes($newwords))."')";
    $DB_site->query("INSERT IGNORE INTO word (wordid,title) VALUES $insertwords");
    $selectwords="title IN('".str_replace(" ","','",addslashes($newwords))."')";
    $DB_site->query("INSERT IGNORE INTO searchindex (wordid,postid) SELECT DISTINCT wordid,$postid FROM word WHERE $selectwords");
   }

   if ($newtitlewords) {
     $newtitlewords=trim($newtitlewords);
     $insertwords="(NULL,'".str_replace(" ","'),(NULL,'",addslashes($newtitlewords))."')";
     $DB_site->query("INSERT IGNORE INTO word (wordid,title) VALUES $insertwords");
     $selectwords="title IN('".str_replace(" ","','",addslashes($newtitlewords))."')";
     $DB_site->query("REPLACE INTO searchindex (wordid,postid,intitle) SELECT DISTINCT wordid,$postid,1 FROM word WHERE $selectwords");
   }

   $DB_site->select_db($dbname);
} 


What am I doing wrong?

Edit: Oh, btw..the echos were there to help me debug..didn't work very well...$val was empty on those echos, except for in the loop...$worddone[$val] was always empty...
