LIB_getContents() 함수에서 preg_replace()를 /e 지시자 때문에 preg_replace_callback으로 대체함.

preg_replace & preg_replace_callback, understood!

Wordpress tips

Child theme's Javascript file is loaded earlier than parent theme's.

For example, global-child.js is loaded right after jquery-min.js loaded and global.js of the parent theme is located at the bottom of <body> tag in the code.

In child theme, JQuery variables without $ should be declared and defined in the $(document).ready().

Weirdly some variables were found 'undefined' in the debugger, if they are defined before/out of $(document).ready() just like twenty seventeen theme's global.js.

Firing a code after a jquery animation:

code it in the callback function of animation().

Firing a code after a CSS transition, for instance, 'transition: 0.6s ease' which is triggered by something like addClass( 'fade-in' ) call:

$("#selector").one("transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd", function(){ ... });

.one() means running the callback only once.

Loading a page/post-specific Javascript:
function load_scripts() {
global $post;
if ( is_page() || is_single() ) {
switch( $post->post_name ) {
case 'home':
wp_enqueue_script( 'home', get_template_directory_uri().'/js/home.js', array( 'jquery' ), '', false);
case 'about-page':
wp_enqueue_script( 'about', get_template_directory_uri().'/js/about-page.js', array( 'jquery' ), '', false);
}
}
add_action( 'wp_enqueue_scripts', 'load_scripts' );

[Google Drive File Stream] I can't connect to other computers? (windows network drive to a shared folder)

Updated Help and Support answer list to a question 'Why I can't connect to other computers?'

I found out today that MS recently updated one of the Help and Support answers about a local network connection in my Windows 7 and it was like the above. Haha...

I was using Google Drive for PC by sharing the 'Google Drive' folder within a local network and connecting the folder from other computers via Network Drive feature of Windows. It was working well as a one-more-depth of security for shared files.
After I installed Google's new 'Drive File Stream' which replaces Google Drive by making another 'My Drive' folder, so I tried to share the folder and it was visible in another computer, but it keeps alerting me the 'permission denied' dialogue. Actually monologue, because there is only one button 'OK' which does nothing for me.
Probably I should go for Backup & Sync for now instead of migrating straightforwardly to Drive File Stream.

P.S. I really like Google and their innovative moves in many different fields and I love their free-to-use software package including Gmail, Google Drive, Google Calendar, etc. Sometimes, however, they give an ordinary user like me a hassle despite following what they recommend; but it's usually untold what really will happen next.
