Im wondering if someone can help me out ... At the moment i have the following code which adds and saves data from a custom meta box in the wordpress admin.

What i want to be able to do, is add a little href that says something like "add more info", which will then render another round of the fields, so i will be able to add as many as i need.

I hope someone can help.

The code i have to render and save just 1 round of fields is as follows:

```
$new_copy_prefix = 'new_copy_';
$new_copy_meta_box = array(
'id' => 'new_copy_meta_box',
'title' => 'Content',
'page' => 'post',
'context' => 'normal',
'priority' => 'high',
'fields' => array(
    array(
        'name' => 'Title:',
        'desc' => '',
        'id' => $new_copy_prefix . 'title',
        'type' => 'text',
        'std' => ''
    ),
    array(
        'name' => 'Content:',
        'desc' => '',
        'id' => $new_copy_prefix . 'content',
        'type' => 'textarea',
        'std' => ''
    ),
)
);

function new_copy_meta_box() {
global $new_copy_meta_box;

add_meta_box($new_copy_meta_box['id'], $new_copy_meta_box['title'], 'display_new_copy_html', $new_copy_meta_box['page'], $new_copy_meta_box['context'], $new_copy_meta_box['priority'] );
}
add_action( 'admin_menu', 'new_copy_meta_box' );

function display_new_copy_html() {
global $new_copy_meta_box, $post;

// Use nonce for verification to check that the person has adequate priveleges
echo '<input type="hidden" name="new_copy_meta_box_nonce" value="', wp_create_nonce(basename(__FILE__)), '" />';        

// Create the code to display teh HTML
echo '<table class="form-table">';

foreach($new_copy_meta_box['fields'] as $field) {
    $meta = get_post_meta($post->ID, $field['id'], true);

    echo '<tr>';
    echo '  <th style="width:35%"><label for="', $field['id'], '">', $field['name'], '</label></th>';
    echo '  <td>';

    switch ($field['type']) {
        case 'text': // The html to display for the text type
            echo '<input type="text" name="', $field['id'], '" id="', $field['id'], '" value="', $meta ? $meta : $field['std'], '" size="30" style="width:97%" />', '<br />', $field['desc'];
            break;

        case 'textarea': // The html to display for the textarea type
            echo '<textarea name="', $field['id'], '" id="', $field['id'], '" cols="60" rows="4" style="width:97%">', $meta ? $meta : $field['std'], '</textarea>', '<br />', $field['desc'];
            break;
    }

    echo '  </td>';
    echo '</tr>';
}

echo '</table>';
}

function new_copy_meta_box_save_data($post_id) {
global $new_copy_meta_box;

// Verify nonce -- Checks that the user has access
if (!wp_verify_nonce($_POST['new_copy_meta_box_nonce'], basename(__FILE__))) {
    return $post_id;
}

// Check autosave
if (defined('DOING AUTOSAVE') && DOING_AUTOSAVE) {
    return $post_id;
}

// check permissions
if ('post' == $_POST['post_type']) {
    if (!current_user_can('edit_page', $post_id)) {
        return $post_id;
    }
} elseif (!current_user_can('edit_post', $post_id)) {
    return $post_id;
}

foreach ($new_copy_meta_box['fields'] as $field) { // Save each option
    $old = get_post_meta($post_id, $field['id'], true);
    $new = $_POST[$field['id']];

    if($new && $new != $old) { // Compare changes to existing data
        update_post_meta($post_id, $field['id'], $new);
    } elseif ('' == $new && $old) {
        delete_post_meta($post_id, $field['id'], $old);
    }
}
}
add_action('save_post', 'new_copy_meta_box_save_data' ); // Save the data

```
