Changing getArrayResult() to getArray() fixes weird Symfony Doctrine gotcha

Aaron Belchamber — Thu, 18 Jun 2015 15:08:31 +0000

A strange Symfony Doctrine issue got me the other day. I guess it’s a lack of clear understanding of how Doctrine hydrates database query results when using getArrayResult() instead of getArray(). It seems that getArrayResult() returns just the first record from your query, no matter how many records the query actually returns but getArray() returns […]

Accessing Symfony global and server variables in Twig views through the “app” variable

Aaron Belchamber — Wed, 10 Jun 2015 11:31:55 +0000

In Symfony, you don’t always have to actually pass values from your controllers to your Twig views. Twig can actually pull global and server values directly through the super global “app” variable. Most frequently, you can access these corresponding objects like Kernel, Request, Security and Session variables like so: {{app.kernel.cachedir}} {{app.kernel.logdir}} {{app.kernel.rootdir}} {{app.request.basepath}} {{app.request.baseurl}} {{app.request.uri}} […]

How to show or access cookie values in Symfony Twig views

Aaron Belchamber — Thu, 02 Apr 2015 15:09:39 +0000

Strange how obscure it is to find a clear example of how to just access or show the value of a cookie in Twig, so here it is! {{ app.request.cookies.get('yourCookieHere') }} Twig is the templating engine that powers Symfony views. Symfony is the PHP framework from Sensio Labs. If you are a company that uses […]

PHP Symfony: Accessing repositories from inside a repository

Aaron Belchamber — Wed, 25 Mar 2015 15:33:59 +0000

Okay, so Sensio Lab’s Symfony is great, but those repositories are a bit limiting in their design scope. I mean, how often do you need to access data through custom database queries and other cross referencing between database tables and not only use one table? Of course, you’re going to have to combine database tables […]

Symfony MySQL Doctrine Mapping Field Type Definitions: TinyInt’s a Boolean, Any Kind of “Text” is Just “text” and Other “Gotchas”

Aaron Belchamber — Tue, 24 Mar 2015 14:23:06 +0000

A MySQL “tinyint” field, regardless of length, is mapped as a boolean in Symfony’s MySQL DBAL platform. Good to know, so when you start typing in those Doctrine ORM mapping files in annotation or my preferred way, YML files, you won’t get a fatal error because you didn’t define the field properly. Here’s a list […]
