  • substitute for {section loop=..

    hi,
    you are saying here that the {section -construct should be avoided in the future. since i'm relativly new to ez-publish i'd like to get used to the the 'right' ways of template programming right from the beginning. but i cannot find a way to loop over results from a fetch differently than the old {section loop=... way.

    i tried it with {while and {for statments with no success..

    what is best practice for looping over results using the new control structures?
    • Re: substitute for {section loop=..

      Hi Patrick,

      You should try the {foreach} statement.
      It works nearly the same way as the section loop.

      If you want to add conditions, then add a {if} statement.
  • An example of using a foreach loop instead of the deprecated section?

    Hi. Could someone provide an example of how to use a foreach loop instead of the deprecated section loop. Let's say I have the following code and want to use a foreach loop instead of a section:
    <div class="listItem">
    {default node_name=$node.name node_url=$node.url_alias}
    {foreach (
    {section show=$node_url}<a href={$node_url|ezurl}>{/section}{$node_name|wash}{section show=$node_url}</a>{/section}{/default}
    </div>
    


    Thanks.
  • Refer to "logical operators"

    Documentation for each of the control statements should refer to this list of "logical operators" that can be used in <condition> clauses:
