Symfony: image_tag() can you change the directory?

When u开发者_运维问答sing the image_tag() method like this:

<?php echo image_tag('whatever.png') ?>

Symfony outputs an image like this:

<img src="/images/whatever.png"/>

By default it uses images as the base images folder in your web directory. Can you change this default folder name in the Symfony config? Say I wanted to use img instead of images...

The config variable is named sf_web_images_dir_name. You can see that in the source here. It can be set via sfConfig::set or through app.yml.

All told, it seems like the easiest way to do this is adding:

<?php sfConfig::set('sf_web_images_dir_name', 'img'); ?>

to the end of app.yml, simply because that is where config stuff is expected, but there are a variety of different ways to accomplish this.

I'm not sure if there is a way to configure this globally in a YAML settings file, but this should be easy to do in apps/frontend/config/frontendConfiguration.class.php (or the equivalent for your application name), using sfConfig::set:

<?php

class frontendConfiguration extends sfApplicationConfiguration
{
  public function configure()
  {
     sfConfig::set('sf_web_images_dir_name', 'img');
  }
}
