How to create new tag
Ex.
I would like to create tag that automaticly includes js and css to
document files from predefined directory like:
<tal:js src="jquery.js">
<tal:css src="style.css">
How to extend tal tags?
TAL doesn't use tags :) Elements in tal namespace are not output.
You could create your own attribute, e.g.
<script xmlns:yournamespace="…" yournamespace:src="jquery.js"/>
The easier option is to use prefilter to change this attribute into
standard TAL attribute (e.g. a macro call or tal:content).
The hard way is to implement it the same way tal:content does it: by
creating your own namespace (PHPTAL_Dom_Defs->registerNamespace()) and
implementing your custom attribute by extending PHPTAL_Php_Attribute
class, that writes code in before/after methods. I don't recommend that,
because it's not documented and requires familiarity with PHPTAL's
internals.
And the easiest solution is to create TALES prefix:
<script tal:content="include:jquery.js" />
function phptal_tales_include($expr, $nothrow)
{
return
'file_get_contents("your_directory/".'.phptal_tale($expr,$nothrow).')';
}
