hi

why my output is not true ?

example :

index.tpl

Code:

{nocache}
{$array = ['key' => 'value',1,2,3]}
----------------------------------
{foreach $array as $key => $value}
{$key} => {$value}
$value@index : {$value@index}
$value@iteration : {$value@iteration}
$value@first : {if $value@first}true{else}null{/if}
$value@last : {if $value@last}true{else}null{/if}
$value@total : {$value@total}
++++++++++++++++++++
{/foreach}
----------------------------------
$value@show : {$value@show}
{/nocache}

output :

Code:

----------------------------------
key => value
$value@index : 0
$value@iteration : 1
$value@first : true$value@last : null$value@total : 4
++++++++++++++++++++
0 => 1
$value@index : 1
$value@iteration : 2
$value@first : null$value@last : null$value@total : 4
++++++++++++++++++++
1 => 2
$value@index : 2
$value@iteration : 3
$value@first : null$value@last : null$value@total : 4
++++++++++++++++++++
2 => 3
$value@index : 3
$value@iteration : 4
$value@first : null$value@last : true$value@total : 4
++++++++++++++++++++
----------------------------------
$value@show : 1

output must be like example below :

Code:

----------------------------------
key => value
$value@index : 0
$value@iteration : 1
$value@first : true
$value@last : null
$value@total : 4
++++++++++++++++++++
0 => 1
$value@index : 1
$value@iteration : 2
$value@first : null
$value@last : null
$value@total : 4
++++++++++++++++++++
1 => 2
$value@index : 2
$value@iteration : 3
$value@first : null
$value@last : null
$value@total : 4
++++++++++++++++++++
2 => 3
$value@index : 3
$value@iteration : 4
$value@first : null
$value@last : true
$value@total : 4
++++++++++++++++++++
----------------------------------
$value@show : 1

Because, as I've said already, Smarty EOL treatment is nontrivial. Some tags eat EOL's, some don't.

This is a known problem. Generated PHP code is enclosed in <?php ?> tags. PHP does eat the line break following the ?> tag.
This is not a problem if none output tags have their own line of template code like

Code:

{if $foo}
text
{/if}
text

If this is not the case as in your example the {/if} should be followed by a space to get the right display in the browser.

This will be removed in the upcoming version 3.2 where we will remove all <?php ?> transitions and echo plain template text.
