For better integration between 5.x (symfony based) kernel and legacy (4.x) kernel, injection is used to inject settings, session and current siteaccess from 5.x into legacy using an event: kernel.event_subscriber

Injected settings

Several settings are injected to avoid having to duplicate settings across new and old kernel, this is done in eZ\Bundle\EzPublishLegacyBundle\LegacyMapper\Configuration.
For mappings below, yml settings prefixed with ezpublish are system settings, while the rest are settings you can define per siteaccess.

For versions 5.1, 5.2 and 5.3

When viewing ini settings in the Administration Interface, settings for other siteaccess may be incorrectly displayed if the configuration has been modified in Symfony configuration.


Database settings

The settings for "Server", "Port", "User", "Password", "Database" and "DatabaseImplementation" are set based on the current settings in your yml files, either from the explicit settings defined below, or the "dsn"


ymlsite.ini [DatabaseSettings]


Storage settings

The settings for "VarDir" and "StorageDir" are set based on current settings in your yml files as shown below.


ymlsite.ini [FileSettings]


Image settings

Some of the settings for image sub system are set based on your yml files as shown below.



Image aliases : image_variations

Note : for image_variations the small value is referenced in ezoe configuration and this configuration needs to be changed if the small variation is removed.


Using ImageMagick filters

The following block shows a valid ImageMagick filter usage example for ezpublish.yml:

ImageMagick filters usage example

Since ImageMagick filter usage changed from eZ Publish 4.x versions you can find the list of filters existing by default to use eZ Publish 5.x:

ImageMagick filters list for yml
sharpen: "-sharpen 0.5"
geometry/scale: "-geometry {1}x{2}"
geometry/scalewidth: "-geometry {1}"
geometry/scaleheight: "-geometry x{1}"
geometry/scaledownonly: "-geometry {1}x{2}>"
geometry/scalewidthdownonly: "-geometry {1}>"
geometry/scaleheightdownonly: "-geometry x{1}>"
geometry/scaleexact: "-geometry {1}x{2}!"
geometry/scalepercent: "-geometry {1}x{2}"
geometry/crop: "-crop {1}x{2}+{3}+{4}"
filter/noise: "-noise {1}"
filter/swirl: "-swirl {1}"
colorspace/gray: "-colorspace GRAY"
colorspace/transparent: "-colorspace Transparent"
colorspace: "-colorspace {1}"
border: "-border {1}x{2}"
border/color: "-bordercolor rgb({1},{2},{3})"
border/width: "-borderwidth {1}"
flatten: "-flatten"

resize: "-resize {1}"

For more details on setting ImageMagick filters on image.ini please refer to the [imagemagick] / filters documentation.

Extending injected settings

It's possible to add your own kernel event subscriber and also inject your own settings by following how it is done in LegacyMapper\Configuration, and then at the end merge it with existing injected settings, like so:


Site settings

You can inject the site.ini SiteAccessSettings in your ezpublish.yml file.


Injected Behavior

In addition to injected settings, some injection of behavior is also performed.

eZFormToken (CSRF) integration

This feature is only available as of eZ Publish 5.1 (2013.01)

If your config.yml setting have framework.csrf_protection.enabled set to true, then both kernel.secret and framework.csrf_protection.field_name will be sent to ezxFormToken class so csrf protection in legacy uses the same token and form field name.

By making sure all your Symfony forms uses the provided csrf protection, forms with intention=legacy can be set up to send data to legacy kernel:

framework.csrf_protection.field_name shouldn't be changed as that would prevent eZFormToken from working with most AJAX custom code

ezpEvent (Cache clear) integration

A listener is set up for both content/cache and content/cache/all to make sure Symfony (Internal proxy or Varnish with custom vcl) HTTP cache is cleared when cache is cleared in eZ Publish admin interface.
