Created 2 years ago by marko60, updated 2 years ago by marko60.

I have been working on a REST API using the excellent tools provided by Yii2. My problem was that I have to differentiate between empty values and null values. In other words, <elem></elem> is different from null as it represents an empty string. Also, although some use <elem/> to represent a null value it should still be interpreted as an empty string. In other cases, the absence of the eleme...

If you are hosting Yii behind a reverse proxy, for example nginx, and you are having issues with your logs showing the proxies IP, or the urls being created arn't being created for SSL because your SSL certs are located on your reverse proxy instead of the Yii server, this code may be able to help you. I placed them in the very top of Yii's entry script, index.php

What SQL-Statement creates yii?

Created 10 months ago by Necip, updated 10 months ago by Necip.

The usual way to find out what Yii has created for an SQL query is to mutilate the SQL in the sourcecode and call the program again so that the SQL statement with errors is displayed. Or you can use the SQL logger, which must be switched on and off each time and logs all SQL statements, which leads to an enormous slowdown in program execution and decelerates your workflow.

Making friends' configs, DB credentials and paths with version control

Created 6 years ago by Alexander Palamarchuk, updated 6 years ago by ajsharma.
