sNews page navigation mod, a mod to hide pages from the navigation menu

This mod will add a checkbox to the "pages" interface in the admin area of your sNews 1.7 installation, like shown in the picture below. What this will do is allow you to create pages that won't be displayed in the pages() function call, yet they won't be hidden from viewing, you can still link to the pages manually.

To start, we need to add the appropriate field to the articles table in your database

ALTER TABLE articles ADD show_in_nav enum('YES','NO') default 'YES';

now BACK-UP your snews.php file work on a copy, now inside function pages, add the following highlighted code

$query = "SELECT id, seftitle, title FROM "._PRE.'articles'." WHERE position = 3 AND show_in_nav = 'YES' $qwr ORDER BY artorder ASC, id";

inside function form_articles, add the following highlighted code

$frm_showonhome = $r['show_on_home'] == 'YES' ? 'ok' : '';
$frm_show_in_nav = $r['show_in_nav'] == 'YES' ? 'ok' : '';
$frm_commentable = ($r['commentable'] == 'YES' || $r['commentable'] == 'FREEZ') ? 'ok' : '';

still inside function form_articles, add the following highlighted code

$frm_showonhome = s('display_new_on_home') == 'on' ? 'ok' : '';
$frm_show_in_nav = 'ok';
$frm_commentable = ($contents == 'extra_new' || $contents == 'page_new' || s('enable_comments') != 'YES') ? '' : 'ok';

still inside function form_articles, add the following highlighted code

echo html_input('checkbox', 'publish_article', 'pu', 'YES', l('publish_article'), '', '', '', '', $frm_publish, '', '', '', '', '');

if ($contents == 'page_new' || $edit_option == '3') {
    echo html_input('checkbox', 'show_in_nav', 'shownav', 'YES', l('show_in_nav'), '', '', '', '', $frm_show_in_nav, '', '', '', '', '');
}

inside function admin_articles, add the following highlighted code

} elseif ($contents == 'page_view') {
    $sql = "SELECT id, title, seftitle, date, published, artorder, visible, default_page, show_in_nav
        FROM "._PRE.'articles'."
        WHERE position = 3 $subquery
        ORDER BY artorder ASC, date DESC ";

now in function processing, add the following highlighted code

$show_on_home = ($_POST['show_on_home'] == 'on' || $position > 1) ? 'YES' : 'NO';
$show_in_nav = $_POST['show_in_nav'] == 'on' ? 'YES' : 'NO';

still in function processing, add the following highlighted code

case (isset($_POST['add_article'])):
    mysql_query("INSERT INTO "._PRE.'articles'."(
        title, seftitle, text, date, category,
        position, extraid, page_extra, displaytitle,
        displayinfo, commentable, published, description_meta,
        keywords_meta, show_on_home, show_in_subcats, show_in_nav, artorder)
    VALUES('$title', '$seftitle', '$text', '$date', '$category',
        '$position', '$def_extra', '$page', '$display_title',
        '$display_info', '$commentable', '$publish_article',
        '$description_meta', '$keywords_meta', '$show_on_home',
        '$show_in_subcats', '$show_in_nav', '$artorder')");
    break;

still in function processing, add the following highlighted code

show_in_subcats='$show_in_subcats',
show_in_nav='$show_in_nav',
artorder = '$artorder'

OK, that should do it for the core php code, now open your language file (EN.php in the lang folder probably) and add the following

$l['show_in_nav'] = 'Show page in navigation menu?';

That should do it, upload your modified files and give it a whirl.

Sven, you mean to hide the category or subcategory from the categories menu, correct?

I ask because to hide a category or subcategory from the home page listings would add another layer of work needed.

Yeap that's right Sir.
Another layer? Forget it. I'm gonna make it... manually.
