Here are some links I’ve come back to quite a few times while developing eZ Publish based sites. Some of the things they tackle are incredibly useful and are hard to track down.

PHP Scripting (for Cronjobs and Other Scripts)

• Running Command Line Scripts
• Fetching Class Type in PHP
• Fetching eZ publish content objects with PHP
• Running Cronjobs manually
• An Introduction to Developing Extensions

Templates

• Pagelayout Variables
• How to Create eZ Publish Forms

Debugging & Optimisation – a great set of articles which are a big help:

• Introduction and Benchmarking
• Identifying trouble spots by debugging
• Practical Cache and Template Solutions
