how to make search query results show up as links to their pages

问题

I am new to php as you can see :)

how can i make the search query results show up as links to their pages. do i need to add to my database a 'links' column in my pages table? Then search_output them out?

    <?php

error_reporting(E_ALL);
ini_set('display_errors', '1');

$search_output = "";
if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
    $searchquery = preg_replace('#[^a-z 0-9?!]#i', '', $_POST['searchquery']);
    {
        $sqlCommand = "(SELECT id, page_title AS title FROM pages WHERE MATCH (page_title,page_body) AGAINST ('$searchquery'))";

    }
    include_once("db_connects.php");
    $query = mysql_query($sqlCommand) or die(mysql_error());
    $count = mysql_num_rows($query);
    if($count > 1){
        $search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />$sqlCommand<hr />";
        while($row = mysql_fetch_array($query)){

            $id = $row["id"];
            $title = $row["title"];


            $search_output .= "";
        } // close while
    } else {
        $search_output = "<hr />0 results for <strong>$searchquery</strong><hr />$sqlCommand";
    }
}
?>
<html>
<head>
</head>
<body>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
Search For: 
  <input name="searchquery" type="text" size="44" maxlength="88"> 


</select>
<input name="myBtn" type="submit">
<br />
</form>
<div>
<?php echo $search_output; ?>
</div>
</body>
</html>

You would need to append all the output from the query fetch, to your $search_output string.

 while($row = mysql_fetch_array($query)){

        $id = $row["id"];
        $title = $row["title"];
        $search_output .= "<a href='".$_SERVER['SERVER_NAME']."/".$title."'>".$title."</a><br>";
        }

But it also depends on how your links look as well, they might not be as simple as above, or might link externally. Then in that case, yes an extra field where you hardinput the link might be useful.

NEW EDIT TO ANSWER NEXT QUESTION...

  while($row = mysql_fetch_array($query)){

        $id = $row["id"];
        $title = $row["title"];
        $link = $row["links"];
        $search_output .= "<a href='".$link."'>".$title."</a><br>";
        }
