/** |

|
|
|
* Loops over an array and moves the scope into each value, allowing for shorter loop constructs. |
26
|
|
|
* Note that to access the array key within a loop block, you have to use the {$_key} variable, |
27
|
|
|
* you can not specify it yourself. |
28
|
|
|
* <pre> |
29
|
|
|
* * from : the array that you want to iterate over |
30
|
|
|
* * name : loop name to access it's iterator variables through {$.loop.name.var} see {@link |
31
|
|
|
* http://wiki.dwoo.org/index.php/IteratorVariables} for details |
32
|
|
|
* </pre> |
33
|
|
|
* Example : |
34
|
|
|
* instead of a foreach block such as : |
35
|
|
|
* <code> |
36
|
|
|
* {foreach $variable value} |
37
|
|
|
* {$value.foo} {$value.bar} |
38
|
|
|
* {/foreach} |
39
|
|
|
* </code> |
40
|
|
|
* you can do : |
41
|
|
|
* <code> |
42
|
|
|
* {loop $variable} |
43
|
|
|
* {$foo} {$bar} |
44
|
|
|
* {/loop} |
