User – URL [.htacess, mod_rewrite] – index.php [route] – path/script-will-be-exec.php [access DB] – data [template] – HTML

Chèn vào đầu file index.php:
if (file_exists(‘offline’)) {
echo ‘Offline!’;
exit(0);
}

// current code

Và thế là mỗi khi muốn làm gì đó (update/upload code, upgrade version, fix bug…), chỉ cần: touch offline
Cách này hay hơn so với:
- Offline nhờ thiết lập cấu hình trong db
- Offline bằng cách tạo index.html và cấu hình ưu tiên index.html lớn hơn index.php (user nhập hẳn index.php thì sao)

mysql -uroot -pRooTIsmE -h mysqlServer

create user special@’%’ identified by ‘password’;
grant all on *.* to special@’%’ identified by ‘password’;
revoke drop, delete on *.* from special@’%’ identified by ‘password’;
flush privileges;
show grants for special@’%';
exit;

mysql -uspecial -ppassword
create database huypv;
drop database huypv;
#ERROR 1044 (42000): Access denied for user ’special’@'%’ to database ‘huypv’

Create new text file: simple-plugin.php
Enter following content:

/*
Plugin Name: Modify Post Content
*/
function modifyPostContent($content) {
return $content . '
This entry is posted by XXX – Thank you for reading’;
}

add_filter(‘the_content’, ‘modifyPostContent’);

Zip it and upload to server to install new plugin. Access your single page and see at end of post.

If you want to use class, you change your code

class YourClassName {
function modifyPostContent($content) {
return $content . ‘
This entry is posted by XXX – Thank you for reading’;
}
}

add_filter(‘the_content’, array(‘YourClassName’, ‘modifyPostContent’));

Vừa nãy bị, vào cPanel thì vẫn okie. Thử /zzz.txt cũng thấy phun ra 500.
Xem qua access log thì thấy bị từ chiều.
Quái, có làm éo gì đâu, hỏi bác support server phát.
