Symfony: Forcing redirects in controller and specifying redirect type

Aaron Belchamber — Tue, 22 Sep 2015 15:11:23 +0000

I recently ran into an issue where I found I was creating a new user profile system for different systems and then it occurred to my: DRY. DON’T REPEAT YOURSELF. Yet, in the bustle of activity I realized there was too much in common with these user profiles to rewrite the code. So why not […]

Here’s how you can check if a session in Symfony was started: if ($this->get('session')->isStarted()){ // Session has been started, so do stuff here } Not a big fan of session variables, but used for non-sensitive session data, I think sessions are still useful.

In normal SQL queries, you can use “WHERE IN” like this: “WHERE id IN (1,5,10)” as in: If the list 1,5,10 “contains” the value represented by the value in the “id” field.
