Zend_Registry::set('paramName');

• iteration_count_log2 controls the number of iterations for key stretching. A setting of 8 means the hash algorithm will be applied 2^⁸ = 256 times. This setting should be kept between 4 and 31.
• portable_hashes controls whether portable hashes should be used or not. Portable hashes are salted MD5 hashes prefixed by $P$.

I have had to do this a couple of times now so I figured I would share it with the community. I am going to keep this short because I really hope that you are familiar with jQueryUI's Sortable class before starting this tutorial.

Using filters on CGridView with CActiveDataProvider is easy, but with CArrayDataProvider it is a bit tricky.

This is what I did. Its the EASIEST solution that I know of. I just reused the advanced search done in CGridView.

[CMenu] offers great functionality and the ability to customize just about every aspect of the output. There are many times when I need to create a drop down menu or simply modify the look to make the designers happy.
