Set Reading Settings Programmatically

by Leave a Comment

Home Page and Post Page settings can be changed manually in the Reading Settings page of the WP Admin Dashboard. With the code snippet below, you can set reading settings programmatically.

The two variables, $home_page and $blog_page, should match the title of a Page you create in the WP Dashboard.

<?php

// Set static front page.
$home_page = get_page_by_title('Home');
update_option('page_on_front', $home_page->ID);
update_option('show_on_front', 'page');
// Set blog page.
$blog_page = get_page_by_title('Blog');
update_option('page_for_posts', $blog_page->ID);

Compare Two Domain Name Values

by Leave a Comment

The code snippet below compares two domain names. One domain name could point to development environment. The other domain name could be a live site on the Internet where visitors go to see the results of your hard work.

All you need to do is set the variable $live_site_url equal to the value of where your live site is found on the Internet. For example, the variable is set to edwinvelez.net which is points the website you are looking at now which is my live site. My development site lives elsewhere which is not on the Internet for you to find.

With the ability to compare locations based upon the domain name values, I can choose to selectively run code without making changes manually.

<?php

*/
// The domain name or host you want to compare. Can also be a host i.e. http://localhost
$live_site_url = 'https://edwinvelez.net';
$head_pattern = '/(https?:\/\/(w{3}\.)?)?(^w{3}\.)?';
$tail_pattern = '(\:[0-9]+).*|\b\/.*|\b\?.*';
$head_vs_tail_boolean = '|';
$regex_flags = '/m';
$regex_pattern = $head_pattern . $head_vs_tail_boolean . $tail_pattern . $regex_flags;
// Strip everything before and after actual domain name and hostname.
$live_site_url = preg_replace( $regex_pattern, '', strtolower( $live_site_url ) );
$site_url = preg_replace( $regex_pattern, '', strtolower( get_site_url() ) );
$is_live_site = strcmp( $site_url, $live_site_url );
// Is the web browser pointing to the live site?
if ( $is_live_site === 0 ) {
// Insert code here to run if this is your live site.
} else {
// Insert code here to run if this is not your live site.
