How to make Wordpress root-relative

Add the following lines to your wp-config file (found in the root).


define('WP_HOME',"http://" . $_SERVER['HTTP_HOST']);
define('WP_SITEURL',"http://" . $_SERVER['HTTP_HOST']);

define( 'WP_CONTENT_DIR',  dirname( __FILE__ ) . '/wp-content' );
define( 'WP_CONTENT_URL',  'http://' . $_SERVER['HTTP_HOST'] . '/wp-content' );
//  added by chetan Custom plugin directory
define( 'WP_PLUGIN_DIR',   dirname( __FILE__ ) . '/wp-content/plugins' );
define( 'WP_PLUGIN_URL',   'http://' . $_SERVER['HTTP_HOST'] . '/wp-content/plugins' );

Then prevent the functions get_site_url() and  get_home_url from accessing the wp_options database table to get the server domain or ip.

For this edit the link-template.php file:

Find the function get_home_url and comment every occurrence of this line like so:
//        $url = get_option( 'home' );

and add this:

    $url = "http://" . $_SERVER['HTTP_HOST'];

Do the same for get_site_url():

//        $url = get_option( 'siteurl' );

and add this:

    $url = "http://" . $_SERVER['HTTP_HOST'];


Now, to make sure any media files that are uploaded use root relative urls, install the following plugin:

VirtualBox Disable Time Sync

vboxmanage setextradata [VMname] "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "1"

Turn it back on:
vboxmanage setextradata [VMname] "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "0"

Buddypress show date and time of post instead of elapsed days and hours

In the themes functions.php add this (the 19800 is 5:30 hours in seconds for IST) :

function format_activity_date() 
{
    $activityDate=bp_get_activity_date_recorded();
    return date("M j, Y G:i", strtotime($activityDate)+19800);
}
add_filter('bp_activity_time_since', 'format_activity_date');
