2016-07-14: Post updated to support both pages and posts without redundant/useless code

Paste the following in the functions.php file of your theme:

// Register the column for modified date
function bf_post_modified_column_register( $columns ) {
    $columns['post_modified'] = __( 'Modified Date', 'mytextdomain' );
    return $columns;
}
add_filter( 'manage_edit-post_columns', 'bf_post_modified_column_register' );
add_filter( 'manage_edit-page_columns', 'bf_post_modified_column_register' );

// Display the modified date column content
function bf_post_modified_column_display( $column_name, $post_id ) {
    if ( 'post_modified' != $column_name ){
        return;
    }
    $post_modified = get_post_field('post_modified', $post_id);
    if ( !$post_modified ){
        $post_modified = '' . __( 'undefined', 'mytextdomain' ) . '';
    }
    echo $post_modified;
}
add_action( 'manage_posts_custom_column', 'bf_post_modified_column_display', 10, 2 );
add_action( 'manage_pages_custom_column', 'bf_post_modified_column_display', 10, 2 );

// Register the modified date column as sortable
function bf_post_modified_column_register_sortable( $columns ) {
    $columns['post_modified'] = 'post_modified';
    return $columns;
}
add_filter( 'manage_edit-post_sortable_columns', 'bf_post_modified_column_register_sortable' );
add_filter( 'manage_edit-page_sortable_columns', 'bf_post_modified_column_register_sortable' );

When you refresh http://<Your Domain>/wp-admin/edit.php or http://<Your Domain>/wp-admin/edit.php?post_type=page the ‘Modified Date’ column will be visible and sortable.

WordPress Network – Jetpack Stats Problem

 in Applications / CMS by

In case you receive a similar error to this:
Fatal error: Call to undefined function get_editable_roles() in ~/public_html/example.com/wp-content/plugins/jetpack/modules/stats.php on line 219
Just visit the dashboard of your website (http://example.com/wp-admin/).
It will make the necessary calls to the Jetpack plugin and fix this error (this error is an initialization error).

Ubuntu Linux: How to install Apache2 – MySQL – PHP (LAMP) phpMyAdmin and fix a few installation errors

 in Applications / Bash / CMS / GNU/Linux / HowTos  tagged apache / apache2 / applications / bash / GNU/Linux / howtos / lamp / mysql / php / phpmyadmin by

We won’t give out pretty much any comments/descriptions for this post because we want to keep it small 🙂

First, install a bunch of stuff:

sudo apt-get install apache2
sudo apt-get install mysql-server
sudo apt-get install php5 libapache2-mod-php5 php5-mysql

Later, restart your apache so that it loads all modules (php, etc)

sudo /etc/init.d/apache2 restart

and if you get the following error:
“Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName” resolve it by adding the line:

ServerName localhost

to the file /etc/apache2/httpd.conf and then try restarting again. (You need root access to edit, if you are not familiar with command line text editors line nano, try sudo gedit /etc/apache2/httpd.conf, gedit is usually available with all gnome installations).

After that, to install phpMyAdmin and make it available at http://localhost/phpmyadmin:

sudo apt-get install phpmyadmin
sudo ln -s /usr/share/phpmyadmin /var/www

(The default MySQL login username ‘root’ and the password is the one you entered during installation in the last step).

Happy developing, hope we helped 🙂
