Using 'or' replicants

bturns

Hey There,

Does anyone have any good code for using "or" replicants in Templating?

in the TPL if there is the possiblity of being an "item1" and "item2" or an "item3" how do you sort through those possibilities in the .tpl. I suppose the code would look something like this. Has anyone done this before?

foreach my $element (iwpt_dcr_list('dcr.Elements')) {
if (iwpt_dcr_value('element.item1')) {

} elsif (iwpt_dcr_value('element.item2') {
}
....................
}

Thanks,

Bt.

I believe this should work:


<iw_iterate list='dcr.Elements.*' var='element'>
  <iw_ifcase name='element'>
    <iw_case type='Or Data Type 1'>
       some logic here
    </iw_case>
    <iw_case type='Or Data Type 2'>
      other logic here
    </iw_case>
  </iw_ifcase>
</iw_iterate>

This assumes that the user has a choice in the replicant of an 'Or Data Type 1' or an 'Or Data Type 2'

Note: this is from the docs, not from actual running code. So take it with a grain of salt.

Thanks. Here is what ended up working

<iw_iterate list='dcr.Body Element' var='element'>
<iw_iterate list='element.*' var='item'>
<iw_ifcase name='item'>
<iw_case type='Image'>
do stuff
</iw_case>
<iw_case type='Link'>
do stuff
</iw_case>
<iw_case type='Paragraph'>
do stuff
</iw_case>
</iw_ifcase>
</iw_iterate>
</iw_iterate>

I just ended up doing something like that also. Combined with processing of component templates, it ends up with three nested iw_iterates, all to process one replicant.

<iw_comment> three iw_iterates to process one replicant
1. iterates over the one item in the container. By doing this, we can
use root.blah references for the item passed from the master tpl
2. iterate over each ContentType element - this is what really iterates
over the replicant
3. iterate over the subelements in content type. This will only iterate
once, and is used to grab the different types for the or replicant.
