How do we reference a specific record from related records?

[ChrissDeGrece]

In the following example I need to output the description for user_info(user_id=1,title=Public) like echo $infos->???????

Is there any way to get this record?

Thanks

Table : Users , PK: user_id
---------------------------------
| user_id       |   username    |
---------------------------------
|  1            |   user1       |
|  2            |   user2       |
---------------------------------

Table: user_info , PK: id , UNIQUE_INDEX: user_id + title
-----------------------------------------------------------------------------
|id             | user_id       |   title       |  description              |
-----------------------------------------------------------------------------
| 1             |   1           |   Public      |  Detailed info for user 1 |
| 2             |   1           |   Private     |  More details for user 1  |
| 3             |   2           |   Public      |  Some secret stuff        |
-----------------------------------------------------------------------------

<?php 
    $user = new User(1);
    $infos = $user->buildUserinfos();
?>

<form action="" method="post">
    <fieldset>
        <p>
            <label for="username">Username</label>
            <input type="text" id="username" name="username" />
        </p>
        <p>
            <input type="hidden" name="userinfos::user_id[]" value="1">
            <input type="hidden" name="userinfos::title[]" value="Public">
            <label for="info_description">Public Info</label>
            <input type="text" id="info_description" name="userinfos::description[]" value="<?php echo $infos->??????? ;?>" />
        </p>
        <p>
            <input type="hidden" name="userinfos::user_id[]" value="1">
            <input type="hidden" name="userinfos::title[]" value="Private">
            <label for="info_description">Private Info</label>
            <input type="text" id="info_description" name="userinfos::description[]" value="<?php echo $infos->??????? ;?>" />
        </p>
        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>
</form>

OK got it:

$infos->filter(array('getTitle='=>'Private'))->getRecord(0)->getDescription()
