When I design a template that refers to some var

e.g.

If my PHP script doesn't set this var, an error is thrown by PHPTal.

I'd prefer if it just went on, rendering it with an empty value for that var.

Is that possible?

Anybody who can help me with this?

I don't know anything about PHPTal, but is it not possible to do something like the following to set a blank title variable?

yes, that is possible. But I don't want to assign values to all possible vars in the template. There are numerous places where you want to foresee that you can add data, but often you don't actually want to do it for this particular page...

Use tal:condition="exists:variablename" before using it.
