2021-08-05Don't check return value of insert/delete methodsThomas Lange1-3/+2
Don't check the return value of the Repository's "insert" and "delete" methods in the administration controllers for creating and modifying entities since a PDOException is thrown if an error occurs.
2021-08-05Show error message if CSRF token does not matchesThomas Lange1-6/+10
Print an error message for various actions in the administration area if the security token is invalid, instead of silently preventing the user's desired action to perform if the token is invalid for some reason. This change applies for the delete actions on all entity types and also for the login action and the database command execution form; the forms for creating/modifying entities had already shown a CSRF error before.
2021-07-01Add category system to categorize posts (readme)Thomas Lange1-0/+56
This commit implements a new category system to categorize posts. Each category can have an unlimited number of nested children categories. A single post don't necessarily need to be in a category, but it can. Each category can have a full content body like posts or pages, so you have enough space to describe the content of your categories. Please note that you need to have at least the following MySQL/MariaDB versions to use the category system, because it uses "WITH RECURSIVE" database queries, the so-called "Common-Table-Expressions (CTE)". MariaDB: 10.2.2 MySQL: 8.0 See: https://mariadb.com/kb/en/with/ See: https://dev.mysql.com/doc/refman/8.0/en/with.html
