Mason Law Gets Responsive Makeover

In January 2012, we relaunched a responsive makeover for Mason Law web site. One of the challenges was that the new design has to work with and response to the existing contents, which being added and updated through  MODX, an open source content management system. Fortunately, MODX’s flexibility doesn’t get in the way and also allowed us to bring the markups up to HTML5.

In making responsive layout, we took the mobile first approach. The entire navigation system is moved to the bottom to allow the content to be more prominent and improve accessibility and SEO. On small screens (smartphones and tablets), users can get to the main content quickly without having to scroll through the menus. On larger screens such as desktops, the navigation is repositioned back to the top using CSS technique.

As an institution, accessibility is one of top priorities; therefore, we make sure the site works well with screen readers and legacy browsers including IE7 & 8. We hope that the new site could help you find information quickly and effectively on any device that you are holding in your hands.

Mason Law Networks

In March 2012, we launched three Mason Law networks using WordPress Multisite:

Upgrade Notes

WordPress: Just hit the upgrade button

MODX: 1.06

  • Follow Upgrading Guide (Alternate Method).
  • Back up config.inc.php and document.parser.class.inc.php
  • Once upgraded, change default sort order in resource tree:if (!isset($_SESSION['tree_sortby']) && !isset($_SESSION['tree_sortdir'])) {
    // This is the first startup, set default sort order
    $_SESSION['tree_sortby'] = 'menuindex'; // Change menuindex to a value of your choice.
    $_SESSION['tree_sortdir'] = 'ASC';
    }
  • PHx Bug & pageTOC issue: The fix is to increase the pcre.backtrack_limit setting in php.inifrom 100000 to 800000

    [Pcre]
    ;PCRE library backtracking limit.
    pcre.backtrack_limit=800000

Modifying the document.parser.class.inc.php

Add the following codes when upgrade:

// START CODE BY PAUL BOHMAN/DONNY TRUONG
// Ability to get all documents, whether deleted or unpublished, added by Paul Bohman
if ($published == '*') $sqlPublished = '';
else $sqlPublished = "AND sc.published=$published";
if ($deleted == '*') $sqlDeleted = '';
else $sqlDeleted = "AND sc.deleted=$deleted";
// END CODE BY PAUL BOHMAN/DONNY TRUONG

And here:

$result= $this->getTemplateVars($vars, "*", $docid, $published, "", "", $sep, $deleted=0);
// The deleted option above was added by Paul Bohman/Donny Truong

Remember to add the codes for CASifying MODX as well.
