i18n All-in-one format and timezone conversions for date, time, timestamp and datetime.

Updated about a month ago by jwernerHow-tos3 comments – viewed 7,016 times – ( +7 / -1 )
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.

There are situations in which Active Record will generate nonsense queries from what a nieve Yii user might think is reasonable code. One such situation is a CActiveDataProvider using CDbCriteria to get data from parent and 1:n child table with a condition on the child table.

Getting the Most out of APC for Yii

Updated 4 months ago by Da:SourcererHow-tos10 comments – viewed 21,916 times – ( +16 ) – version 1.1
The Advanced PHP Cache is a PHP extension which primarily serves as an opcode cache for PHP. The basic idea is to save PHP from re-evaluating the PHP code to intermediate bytecode on each request. Installing and enabling APC already yields a significant performance benefit. However, APC is not a black box that will magically change all for the better. More over it is important to understand that APC needs memory to operate.

First declare an attribute to store the file name in the model class (either a form model or an active record model). Also declare a file validation rule for this attribute to ensure a file is uploaded with specific extension name.

Dynamic Sidebar using CClipWidget

Updated 4 months ago by CozumelHow-tos5 comments – viewed 20,519 times – ( +21 ) – version 1.1
Most applications will have one or two sidebars and often you want to control the content that should appear in the sidebar based on the action. For example you will want to show something different on the homepage as opposed to some view page. While achieving this you generally also want to avoid putting the layout into each view, as that would mean if you wanted to change the layout (e.g. put the sidebar on the left instead of the right or do some funky layout which requires an additional div tag to be added) you'd have to go through every view, which does not achieve good code re-use. It is also bad practice to have lots of if statements in column2 layout just so that you can generate the sidebar correctly.

Drop down list with enum values for column of type ENUM >+> incorporate into giix

Updated 4 months ago by nsandenHow-tos2 comments – viewed 20,554 times – ( +14 ) – version 1.1
Let's say our table 'mug' has a column named 'color' of the type ENUM('red','green','blue'). We want to replace the textfield for the attribute color in the create and update forms of a 'mug' with a drop down list, which has the enum values as options. The main code was contributed by zaccaria in the forum (see this post).
