Most of the currently available functions/extensions/behaviors directly or indirectly use timestamps to perform "format" and "timezone" conversions. This creates problems for dates falling outside the timestamp range; and the two forms of conversions must often be done in separate processes. However, by using php's DateTime class (instead of timestamps), we can do both conversions on a single DateTime object (only 2 lines of code) for date, time, timestamp and datetime types - while php takes care of nightmares such as daylight saving times and more importantly, historical changes in timezones and daylight saving times.
In SQL, wildcard characters can be used in "LIKE" expressions; the percent sign (%) matches zero or more characters, and underscore (_) a single character. Sometimes users are not familiar with these or they are using different ones like (*) and (+) similar to regular expressions. My colleages do so and then i decided to add this feature by extending CbCriteria. Especially adding a new parameter $wildcard_chars to the method addSearchCondition to replace them if needed with standard SQL characters:
The Yii Framework provides a sweet functionality that allows you to easily create page specific menus.
What does this mean?
This allows you to create one layout or CSS styling for your menu, and when each page is loaded, a new set of menu items is loaded in. This is useful for context specific sidebars within your application.
This article shows one of possible ways to implement menu items (as well as links), which displays a progress / wait dialog and are redirecting browser to destination URL in the same time. This is especially useful, for links or routes that are know to be loaded for a prolonged period of time (i.e. getting a lot of data from database).
I have been trying to find information on how to sync the sessions between Yii and KCFinder so that the two applications can "communicate" with each other. I managed to find some bits and pieces on the correct approach to use, but not a definite guide or concrete code.
