This is a more precise way to get the list of activated theme on each blog in your WordPress Multisite:

You can use this: 1. Install wp-cli . 2. Create a bash script (export_blog_theme.sh) with the following content #! /bin/bash for url in $(wp site list --field=url --path=/path/to/your/wordpress/root) do         theme=$(wp option get template --url="$url" --path=/path/to/your/wordpress/root)         echo "$url,$theme" done 3. Make script executable: $ sudo chmod +x export_blog_theme.sh 4. Run the script: $ sudo -u www-data ./export_blog_theme.sh > blog_theme_list.csv Notes: Sometimes, the script return no result because of caches or WordPress db connection limitation.

A couple weeks ago, I'm working on a project that required me to develop a WordPress theme. One of the things that interested me was to create a block (html, in the front page) that change its background image randomly every time I reload the page. Here is how I did that: The main idea here is using Ajax to dynamically change background of a div tag to a random image loaded from a folder inside the theme's root every time I reload the home page. 1. functions.php add_action('init', 'enqueue_scripts_styles_init'); function enqueue_scripts_styles_init () { wp_enqueue_script( 'ajax-script', get_template_directory_uri().' /js/myscript.js ', array('jquery')); wp_localize_script( 'ajax-script', 'ajax_object', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) ); } add_action('wp_ajax_get_rand_img', 'get_rand_img'); add_action('wp_ajax_nopriv_get_rand_img', 'get_rand_...

OK, Is your WordPress page rarely get updated, let's say once a day or a week. If so, you can use the following technique to reduce the load (queries) to the database especially in multisite deployment: Write a script to generate static content with updates from the database only once a day or a week. Then your users will access this static page instead of the heavy loading WordPress page with hundreds of database queries. 1. Create a wordpress template file wp_template.php (place it in your template root, e.g. /var/www/wordpress/wp-content/themes/mythemes/) which will get data from the database. For example: 2. Create a crontab to run this command every day at 1AM to generate the static html file in the web root: /usr/local/bin/blog_static_gen.sh: #! /bin/bash $ cd /var/www/wordpress/wp-content/themes/mythemes $ php wp_template.php > /var/www/wordpress/wp_template.html crontab: 0 1 * * * /usr/local/bin/blog_static_gen.sh 3. Then you can access the static co...

To integrate Bootstrap 3 navigation menu to WordPress you can use the following walker class: https://github.com/twittem/wp-bootstrap-navwalker But, the problem is it only allows a single dropdown level to honer BootStrap 3's mobile first philosophy. Fortunately, the guy this blog post had done a little hack to bootstrap and the walker class above to support multilevel drop-down menu: Blog post: http://www.jeffmould.com/2014/01/09/responsive-multi-level-bootstrap-menu/ Github repo: https://github.com/jeffmould/multi-level-bootstrap-menu Basically, what you should do to have a bootstrap 3 style dropdown menu in your WordPress theme are: 1. Copy the  wp-bootstrap-navwalker.php file from the github repo to the theme's root directory 2. Add this style to your theme: .dropdown-submenu{position:relative;} .dropdown-submenu>.dropdown-menu{top:0;left:100%;-webkit-border-radius:0 6px 6px 6px;-moz-border-radius:0 6px 6px 6px;border-radius:0 6px 6px 6px;} .dropdo...

From last night, whenever I tried to access the feed url of my Wordpress blog, I saw this error: This page contains the following errors: error on line 12 at column 49: Entity 'ndash' not defined Below is a rendering of the page up to the first error. So, here is how I fixed it: 1. First, go to the online feed validator tool to see what was wrong: http://feedvalidator.org/ Enter my blog feed url and see the result. It turned out that there is something wrong with the feed title tag. It includes a strange character called – 2. Go to the template's include folder, open the template file which defines the feed's title and remove that character. I'm using genbu theme, so I will edit genbu/includes/tamatebako.php , the   tamatebako_wp_title function as following line: ...         /* Add Site Description */         if( is_front_page() ){                 if ( $site_description )...
