Basic rules

Let's start with the basic rules:

Rule 0 (Zeroth): Everybody is welcome to the Tiki developers community, if you need help ask if you want to try try, if you want us to review your work send it.

1. Tiki pages are always compunded by two files: a php file and a template. All the logic and PHP code goes in the PHP file and all the presentation, displaying and layout goes to the template.
2. All the database-access funcionality is abstracted into libraries in the lib directory, tikilib is the system library for tiki core modules.
3. PEAR is used in libraries and only in libraries to access the databases, direct DBMS functions such as MySQL API functions are not used.
4. All the strings are written to be easily translated using the tra function in PHP or the {/tr} blocks in templates.
5. All your HTML code must be XHTML 1.0 transitional compatible, use the W3C validator to check your module before releasing it.
6. Put style to your XHTML code using CSS stylesheets.
7. Everything must work with all the warnings and errors reported
8. Everything must work if register_globals is turned off
