Blocks settings : Items proposal (custom fetch)
Override : block.ini.append.php FULL exemples : ezflow/classes/fetches/…

Blocks settings : custom attributes
Override : block.ini.append.php Browse and add one unique node (for instance a parent node id) Integer String Collected values are available inside your templates !

Blocks settings : views list
Override : block.ini.append.php Advice : Factorize your block list « how to select items, and input values » (1 block if similar), « how to display the selection ? » (X views) For instance : Display an image selection with X views (diaporama, list, carousel, sliders…)

Blocks settings : block templates
Override : block.ini.append.php override.ini.append.php

Common issues : view cache expiry (from reverse related items)
Not possible (by default), only a TTL (expiration time) Solution : http://issues.ez.no/IssueView.php?Id=17324&activeItem=1 kernel hack : kernel/classes/ezcontentcachemanager.php [ViewCacheSettings] SmartCacheClear=enabled ClearRelationTypes[] ClearRelationTypes[]=common ClearRelationTypes[]=reverse_common ClearRelationTypes[]=reverse_embedded ClearRelationTypes[]=reverse_attribute ClearRelationTypes[]=attribute ClearRelationTypes[]=reverse_ezflow

Common issues : limit the block list for each classes / zones
Not possible (by default), same block list for all classes / zones Solution : http://projects.ez.no/ca_ezflow_enhanced Owner : Matthieu Sévère [myblock] … AvailableForClasses[] AvailableForClasses[]=global_layout AvailableForClasses[]=frontpage AvailableForZones[] AvailableForZones[]=frontpage|main AvailableForZones[]=frontpage|right AvailableForZones[]=global_layout|left

Common issues : add new custom attributes datatypes
Not possible (by default), only « integer », « string », « browse » override : /design/standard/templates/block/edit/edit.tpl Exemple with a « selectbox »: http://projects.ez.no/ca_ezflow_enhanced Owner : Matthieu Sévère

Common issues : cache-block optimisation / article right column & default right column
ARTICLE_FULL.TPL Article_full.tpl : Store your article right column with ezpagedata With ezpagedata , get back your right column inside your pagelayout.tpl Fetch the default right column , and display it if the article right column is empty Set a cache-block around ezpagedata ezpagedata

So… what’s the main benefits to use eZ Flow ?
Less classes, more blocks… easier to deployed & maintain (manage settings files & template only)
Build your block collection, and share it for all your projects
You could ( but please don’t ! ) build a website with an unique « article » content class, and… Blocks
