while writing new code and testing it, I incorporate it into my site by testing for the remote IP address as follows; i.e., I'm the only one who will see the new code:
// to hide certain sections/features from people other than myself $myIP = '188.8.131.52'; // the value as currently indicated by Airport Utility if( FALSE ) // set to TRUE to initiate Remote Addr test define( 'ITS_ME', $myIP == $_SERVER['REMOTE_ADDR'] ); else define( 'ITS_ME', FALSE );
in a template; eg,
if( ITS_ME ) // IN DEVELOPMENT echo gregory_get_featured_announcements();
in addition, five domains point to my server because I'm known by 5 different names in various languages. I use
$_SERVER['HTTP_HOST'] in a filter function hooked to
site_url() that sets the domain of internal links to the host that the visitor specified.
I'd like to know; is it likely that these will put a heavy load on the server? would a cache plugin like
W3 Total Cache help?
my apologies. the question is difficult to understand. s_ha_dum is right. I'm testing on the live server. What I'm doing would never be done in a professional setting. I'm developing my own personal blog.
ITS_ME is a switch which evaluates to TRUE if the visitor loading the site has my IP address; i.e., the visitor is me. If the switch is on, the code within
if( ITS_ME ) conditionals gets executed. This code could be in any of my WP templates. The switch is also used within
functions.php to selectively
require() in-development WP files.
wrt the domains, if a visitor visits me at domain1.com, all of the internal links will be based on domain1.com. if they visit domain2.com, all of the internal links will be based on domain2.com but otherwise, they're seeing exactly the same content. please see http://wordpress.stackexchange.com/a/73621/15311
