Break in Smarty's / Dwoo's foreach

问题

About break

foreach ( $data as $k => $v ) {
  if ( $k == 4 ) {
    break;
  }
}

every one knows.

Is there something similar in Smarty's or Dwoo's {foreach} function ?

回答1:

You should put your logic in php, not in template. However, you can write your own compiler plugin:

function smarty_compiler_break($contents, &$smarty){
   return 'break;';
}

and save it to compiler.break.php in your plugins directory.

Now in template you can use {break}.

@Antonio: typical PHP developer retort, indeed :) Using Smarty largely depends on app requirements and developer/designer preferences. Here are some typical use case examples, and how Smarty plays a role:

If you don't like it, don't use it. Shunning Smarty in general is just showing your ignorance for what it may offer for others.
