 Posted: Sat Jun 05, 2004 1:48 pm Post subject: foreach and $default_modifiers |
 |
|
hi, list.
I'm seeing strange interaction between {foreach} and $default_modifiers.
in short: {foreach} applies $default_modifiers *twice*
I've google'd and read document, but cannot find anything.
so here goes my question.
first, my environment is:
smarty 2.6.2
apache 1.3.31
mod_php4 4.3.6
mod_ssl 2.8.18_3
Mozilla-1.6
now here's sample code.
[php:1:e3d763816d]<?php
define('SMARTY_DIR', '/dir/to/smarty/') ;
require_once( SMARTY_DIR.'Smarty.class.php' ) ;
$s = new Smarty() ;
$s->compile_dir = realpath(SMARTY_DIR.'../templates_c/');
$s->template_dir = realpath(SMARTY_DIR.'../templates/');
$s->default_modifiers = array('escape:"htmlall"');
$s->assign('ary', array('this should be seen as <html>'));
$s->display('test.tpl');
exit;
// NOTREACHED
?>[/php:1:e3d763816d]
and template
| Code: |
{* test template for foreach begin *}
{foreach from=$ary item='fe'}
{$fe}
{/foreach}
<br />
{section name='sct' loop=$ary}
{$ary[sct]}
{/section}
{* test template for foreach end *}
|
here's output from mozilla.
| Quote: |
this should be seen as &html&
this should be seen as <html>
|
as you can see, foreach's output looks like escaped *twice*.
BTW, section's output looks correct.
actually, I've checked compiled template and found that $default_modifier is applied to subject variable when count() is used to know how many times to loop, and applied again when variable is being output.
yes, I can use {section} instead of {foreach} to avoid this problem, but {foreach} is very convenient way to loop through array, and this behaviour looks incorrect to me.
can anyone confirm this ?
does anyone know how to workaround ?
sorry if this is known problem... and sorry for broken english.
thanks in advance.

oh, yes!!
that's really a solution.
thank you very much for pointing me out.
now I've changed template as following
| Code: |
{* test template for foreach begin *}
{foreach from=$ary|smarty:nodefaults item='fe'}
{$fe}
{/foreach}
<br />
{section name='sct' loop=$ary}
{$ary[sct]}
{/section}
{* test template for foreach end *}
|
I get correct output:
| Quote: |
this should be seen as <html>
this should be seen as <html>
|
# this is counter-intuitive, IMHO.
Is this a FAQ ?
thank you very much for very quick reply.
I didn't think I get a reply within an hour.
that's really geat !!

hi, list.
followup to myself, I think I've found simular interaction between {if} and $default_modifier, as in {foreach} and $default_modifier.
the code:
[php:1:58c76a9d8b]<?php
define('SMARTY_DIR', '/dir/to/smarty/') ;
require_once( SMARTY_DIR.'Smarty.class.php' ) ;
$s = new Smarty() ;
$s->compile_dir = realpath(SMARTY_DIR.'../templates_c/');
$s->template_dir = realpath(SMARTY_DIR.'../templates/');
$s->default_modifiers = array('escape:"htmlall"');
class foo {
var $m_var;
};
$foo = new foo();
$foo->m_var = 'this should be seen as <html>';
$s->assign('foo', $foo);
$s->display('test.tpl');
exit;
// NOTREACHED
?>[/php:1:58c76a9d8b]
with following template, I get blank page.
| Code: |
{if $foo}
{$foo->m_var}
{/if}
|
if I use following template(i.e. using smarty:nodefaults)
| Code: |
{if $foo|smarty:nodefaults}
{$foo->m_var}
{/if}
|
and I get correct output as follows:
| Quote: |
this should be seen as <html>
|
can anyone confirm this ?
and if this is the case, be careful if you're using object(not array) and $default_modifiers at the same time.
just FYI.
