Store Custom Data
Store custom data for an extension

Understanding and Working With the miniCal POST and POST-META Tables

Suppose you are building an extension that requires a database to save the extension specify info. For instance, you need to capture username and mail-id so these details will go on the "post" and "post-meta" tables.

Understanding and Working With the miniCal OPTIONS Table

The options table stores a different kind of data from the other tables: instead of storing data about your extension content, it stores data about the application itself. miniCal provides a set of functions to add, update and delete data from this table. You can add values to existing options and you can also add new records to the table when you want to create new options.
