Avoiding duplicate script download when using CActiveForm on Ajax calls

Created 3 years ago by Antonio RamirezTutorials2 comments – viewed 17,071 times – ( +12 / -1 ) – version 1.1
Sometimes the active form we wish to use to edit/add a new element on our database is too small and we believe that is much better to use an AJAX'ed dialog/slide form rather than reloading the page to just display one or two fields.

Customizing Yii's formatting rules (extending CFormatter)

Created 3 years ago by HaenselTips0 comments – viewed 14,436 times – ( +14 ) – version 1.1
CFormatter is one of Yii's core components and used to format values displayed in widgets like CGridView or CDetailView. All classic formats like numbers, text, urls or datetime are supported but you may have to use a formatting rule that isn't built in. Let's say we want to display arrays of strings (like tags associated with a product model). When using CDetailView we would usually make use of PHPs implode function to create a simple string value of all values in the $product->tags array.

Sometimes it would be nice if we could run yiic from an action, for example a migrate database button in our admin panel. Or because you are on a host which doesn't have shell access. Or maybe you are not allowed run popen or exec.
