can't figure out a loop that works

I have an edit.php page with a form on it that pulls the selected journal entry up for edit. So what I'm TRYING to do is get the form to automatically fill in the data for the links that are already in the database for that page (which I was able to do successfully) and THEN add empty input areas for adding links IF that page has less than 3 links (I'm trying to allow for all pages to store a max of 3 links (so for instance if a page currently only has one link associated with it then I'd want that link to be listed first and then 2 empty inputs or whatever) Here's what I have:

$i = 0;
                while($i < 3) {
              foreach($resources as $link) {

                  if($link['journal_id'] == $get_id['journal_id']) {

                    echo '<label for="link_name">Enter name for link:</label>';
                    echo '<input id="link_name" type="text" name="link_name" value="' .$link["link_name"] .'">';
                    echo '<label for="link_address">Enter web link here:</label>';
                    echo '<input id="link_address" type="text" name="link_address" value="' .$link['link_address'] .'">';
                      $i++;
                    }

                }

                      if($i < 3) {
                        echo '<label for="link_name">Enter name for link:</label>';
                        echo '<input id="link_name" type="text" name="link_name[]">';
                        echo '<label for="link_address">Enter web link here:</label>';
                        echo '<input id="link_address" type="text" name="link_address[]">';
                        $i++;
                                }
                }
```?>

I've tried all sorts of different loops, and loops within loops etc.  Can't seem to figure this one out!  Any help would be appreciated.
