OPTv2: Appending or Multiple values for an attribute

[duclet]

In constructing my menu, I want to be able to have code which would do something similar to the following:

Code:

<a href="...">
<opt:attribute name="class" value="last" opt:if="$menu.is_last" />
<opt:attribute name="class" value="active" opt:if="$menu.active" />
Link Text
</a>

Obviously that doesn't work because I can't redeclare the same attribute. I can't wrap the entire thing around an if block either since the parent won't be the anchor tag anymore. Is there any way to append the values?

Yes, of course. Take a look at this:

Code:

<a href="...">
<opt:attribute str:name="class">
    <opt:value test="$menu.is_last">last</opt:value>
    <opt:value test="$menu.is_active">active</opt:value>
</opt:attribute>
Link Text
</a>

Just note that there was a small bug in the implementation - if none of the conditions was true, the instruction still generated the empty tag: <a class=""> (where it should not generate any in this case). It is fixed in SVN right now and if you like, you can download the fixed code from there.

But would that append to the value? So if the last item in the menu is also the active item, it would become "last active"?

Then you can do:

Code:

<a href="...">
<opt:attribute str:name="class">
    <opt:value test="$menu.is_active and $menu.is_last">last active</opt:value>
    <opt:value test="$menu.is_last">last</opt:value>
    <opt:value test="$menu.is_active">active</opt:value>
</opt:attribute>
Link Text
</a>

The true appending will be possible in OPT 2.1 which will contain the swiss knife: opt:switch.

Yup, I am currently doing that. I was hoping there was a more efficient way. Well, can't wait until the 2.1 release. Thanks.
