Upload files in Yii2 with MongoDb and GridFs

Updated 2 months ago by skwordenHow-tos3 comments – viewed 8,797 times – ( +8 ) – version 2.0
Uploading files in a webapp can be extremely tricky and sometimes the quickest way to do it is to store the file directly in the webserver or into a DNS (like Amazon S3) and then to save the link and the metadata inside a table in the DB. The thing is that you'll have to deal with file permissions, server storage, file management and so on (which is perfectly fine, by the way).

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

Updated 2 months ago by Gerhard LiebenbergHow-tos3 comments – viewed 12,997 times – ( +7 / -1 ) – version 1.1
Countries sometimes change their laws pertaining to timezones and daylight saving times. This means that GMT+2 can be a different time this August compared to last August! However, by using php's DateTime class (instead of timestamps), we can do both "format" and "timezone" 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 current and historical timezones and daylight saving times.

Yii configuration: Dynamic & User dependent

Updated 3 months ago by le_topHow-tos0 comments – viewed 2,085 times – ( +1 ) – version 1.1
It is difficult to perform user dependent theming through a general configuration in 'main.php'. This article proposes a method to do so through a Factory that dynamically generates classes to allow delayed resolution of actual user values. This means that you can refer to values that are stored in the database through the CActiveRecord before Yii is actually loaded. The values will be fetched from the database when actually used for the first time, which is after Yii is loaded. Actually, you can use pretty much any method that relies on Yii with this method.
