Upgrading to PHP 7

This guide is for CentOS Linux systems running PHP 5.3 and up.

Start by logging into WHM and making sure the server is on Apache 4. Use EasyApache 4 to upgrade if necessary.

To upgrade PHP 7, SSH into the server and download Remi and EPEL Repository:

$ wget -q http://rpms.remirepo.net/enterprise/remi-release-7.rpm
$ wget -q https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Enable the respositories:

# rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm
# yum-config-manager --enable remi-php70
# yum-config-manager --enable remi-php71

Then upgrade to PHP 7:
# yum update

Events Planning Form Using Javascript

A short questionnaire to direct users to the right form using Javscript
window.onload = function() { document.getElementById('link1').style.display = 'none'; document.getElementById('link2').style.display = 'none'; }; //Clears div box

var x, y, z; //assigns variables to radio selections

function a1(answer1){ x = answer1; };
function a2(answer2){ y = answer2; };
function a3(answer3){ z = answer3; };

//if all answers are no, display link2 and hide link2; if any answers are yes, do the opposite.

function showdiv() { if (x==1 | y==1 | z==1){ document.getElementById('link1').style.display='block'; document.getElementById('link2').style.display='none'; } else { console.log("None of the questions is 1"); document.getElementById('link1').style.display='none'; document.getElementById('link2').style.display='block'; } return; }

//How to structure your HTML to code. Onlick assigns value to x,y,z variables

<input type="radio" onclick="a1(1)" name="q1">Yes
<input type="radio" onclick="a1(0)" name="q1">No

//execute code
<button onclick="showdiv()">What Form Do I Need?</button>

//hide show divs using IDs
<div id="link1">
Link 1
<div id="link2">
Link 2

Creating Working Papers

Faculty Working Papers are created in one of two categories. This guide goes over both Law & Economics Working Papers as well as Legal Studies Working Papers.

Step 1. Navigate to the Faculty Working Papers directory on MODx found under: Resources > Publications > Faculty Working Papers

Create a New Article by selecting the New Article button.

Step 2. Name the article using the Article Title field.

Step 3. Scroll down the same page and under the Uses Template field, select Publications – Working Papers template found on page 3 of the drop down menu.

Step 4. Navigate to the Template Variables tab and make sure you are on the Documents sub-section.

Enter the Title & Publication Year/Month/Day

Depending on the category, Either the Law & Economics No. field OR the Legal Studies No. field must be filled in. The naming convention is subject to change. Please contact the Head of Reference and Instructional Services for the most up to date information.

Step 5. Under Text Availability select Abstract and Full Text and SSRN. Almost all working papers include all three items. Then upload a PDF copy of the working paper using the PDF field. Make sure it’s under the publications/working_papers directory.

Step 6. Paste the abstract into the Abstract text field. The abstract is usually included in the working paper. If not, the first paragraph will usually suffice.

Step 7. Select the Author(s) from the checklist.

Step 8. In this field, Type the ID numbers of each author. If there are multiple authors, separate each by a comma (e.g.:  123,456,789). Do not include a blank space between IDs.

Step 9. Scroll back to the top and select the Publications sub-section, still under Template Variables. Under SSRN Of Document, paste the SSRN link provided to you. This link is provided usually provided by a Scalia Law staff member.

Step 10. Finally, select Save to publish the Working Paper.

List All Sites Using Custom Shortcode

Shortcodes make it easier to customize wordpress pages quickly. WordPress comes with pre-built shortcodes but we’re going to build one from scratch. You will need to add a function to your child theme’s functions.php file. This particular code builds an ordered list of all our wordpress sites under our sls.gmu.edu domain using the get_sites() function. This function will work on all WP platforms 4.3 and above.

* Author: Tushar
* This function creates a shortcode usable in all sites using the scalia law theme to create an ordered list of
all multisites
function scalia_list_sites() {

$subsites = get_sites(); //creates variable using get_sites

if ( ! empty ( $subsites ) ) {

$html = '

    '; //sets up class

    foreach( $subsites as $subsite ) {

    $subsite_id = $subsite->blog_id; //finds sites by id
    $subsite_name = get_blog_details( $subsite_id )->blogname; //creates variable for site name
    $subsite_link = get_blog_details( $subsite_id )->siteurl; //creates variable for site url
    $html .= '< li class="site-' . $subsite_id . '">< a href="' . $subsite_link . '">' . $subsite_name . '< /a >< /li >'; //builds individual list items

    $html .= '< /ol >';

    return $html; //returns the list


    add_shortcode('scalia_list', 'scalia_list_sites'); //calls function and sets up [ scalia_list ] custom short code

    This goes in your child-theme’s functions.php file.

Adding News Articles

This is specific to the Monthly Dean’s List Mailings found here.

1. Create a Resource using the News template. Give it a Title, Long Title, and Resource Alias.

2. On the Settings Tab, make sure the Parent Resource corresponds to the News>Year. The Published On field will be used to sort the article. Use the date the Mailing was delivered.

3. Under Template Variables, include an image (300px wide by 200px high). Copy and paste a blurb for the Spotlight/Feature Summary (usually the first sentence). Enter the Publication Date. Check off the categorie(s) that correspond to the article on the Categories list. Under Content, paste the entire article.

4. If an image needs to be included, upload the image and use the following code template:

<figure class="floatleft">
<img src="assets/images/news/mossoff_adam.jpg" alt="Professor Adam Mossoff" />
<figcaption>Professor Adam Mossoff</figcaption>

Course Pages

At this point the Staff Bio page has all the required information to display correctly. You will need to select the green SAVE button found at the very top of the page to save your work and publish your page.

Optional: You may add additional information such as uploading a resume, including a professional website link, or Twitter username found in the People and Locations sub-tab, respectively.


Force Update of PDFs

When replacing an existing PDF, browsers don’t serve the latest version. They usually serve the cached version. To change that, we use Apache directives as below:

# Instruct browsers to always check for the latest version of your files using Apache directives
<IfModule mod_headers.c>
<FilesMatch "(?i)^.*\.(css|htm|html|gif|jpg|jpeg|js|png|pdf)$">
Header set Cache-Control "max-age=0,must-revalidate"

The instruction above includes more than just PDF.

Another solution is using ?ver=x.x in the URL. For example:


x.x could be any number.
