One Laravel codebase with multiple databases and hostnames

WordPress Users, Roles and Capabilities

I find the capabilities one of the most difficult to grasp concepts in WordPress development. On one hand, you have the capabilities of a custom post type and on the other hand you have the capabilities of a user or user role.

Show custom post types in category archives

Custom post types are not displayed in the category and tag archives by default, even if you indicated in the register_post_type call that it should support these taxonomies.

Store mcrypt values from PHP in MySQL

The mcrypt functions return a binary string, so you can store it in a VARBINARY or BLOB field or as VARCHAR or TEXT if you first base64 encode it. When using the CBC (Cipher Block Chaining) mode, the input is divided into blocks of X bytes. The last block is then padded with NULL bytes […]
