I'm creating a form elements template file in PHPTAL. I would like to be able to OPTIONALLY pass in an id attribute for a field...
So far the code looks like this:
<xml>
<tal:block metal:define-macro="text">
<label tal:condition="php: !isset(hideLabel) || isset(hideLabel) && !hideLabel">${field/label}</label>
<input name="${name}" type="text" value="${field/value}" />
<p tal:condition="exists:field/error">${field/error}</p>
</tal:block>
</xml>
This works as advertised. What I'd like to add is something, like
<input name="${name}" tal:attributes="id exists: id $id | $name" value="${field/value}" />
to allow me to optionally pass in an id from the METAL call...
Should I be doing it differently? I've tried using PHP: isset(id) ? $id : NULL
and variations thereof, but just end up with an id="0"
in the resultant HTML.
Any ideas?
