The task is to make tabs in jquery.

To create a convenient pop-up user authorization form, it took the JQuery library and the Fancybox plugin. By the way, you can download libraries to your project folders or use links to them (for example, to code.google.com).

The simplest example of using a session and cookies, for example, to calculate page traffic by a specific user.

An N-dimensional product catalog, then between a catalog with subcategories of unlimited nesting, The idea is such that a product can have a minimum of one, and a maximum of N (Well, for starters, N is at least 5, but the idea is to make it NOT limited) and if pure category (pid=0) you can create either a product or a subcategory. If we create a subcategory, then the id of the parent category (genus, cat,) is written in the pid field of this newly created subcategory, and from now on, only subcategories can be created in the genus, cat (products are no longer possible), until all subcategories. And if we create a product in genus, cat, then in the product table, the link_id field of the created product is assigned the id genus, cat, and in it we can now create only products until all products are deleted from the table.
