标题: smarty3中block的研究
本帖最后由 zhgc 于 2019-9-11 15:08 编辑

函数结构：
function smarty_block_translate($params, $content, &$smarty, &$repeat) //smarty2
function smarty_block_translate($params, $content, Smarty_Internal_Template $template, &$repeat) //smarty3
判断的官方方法：

// 只在结束标签时输出
if(!$repeat){
if (isset($content)) {
$lang = $params['lang'];
// 翻译$content的内容
return $translation;
}
}

复制代码

$repeat默认只有第一次为ture, $content默认第一次为null

1. 研究函数体内smarty的数据类型
加入以下代码，得到类名称

function smarty_block_nagomenu($params, $content, &$smarty, &$repeat) {
// Smarty_Internal_Template
trigger_error(get_class($smarty), E_USER_NOTICE);
// MySmarty
trigger_error(get_class($smarty->smarty), E_USER_NOTICE);
}

复制代码

2. 研究_tag_stack对象

加入以下代码

function smarty_block_syant($params, $content, &$smarty, &$repeat) {
echo $content;
var_dump($smarty->smarty->_tag_stack);
}

复制代码

模板内容：
{syant  aa=1 bb=2}
{wj mm=9}{/wj}
{/syant}
得到的结构：
一层：
array(1) {
  [0]=> array(2) {
[0]=> string(5) "syant"
[1]=>  array(2) { ["aa"]=> int(1)  ["bb"]=>  int(2) }
  }
}
二层：
array(2) {
  [0]=> array(2) {
[0]=> string(5) "syant"
[1]=> array(2) {  ["aa"]=> int(1)  ["bb"]=> int(2) }
  }
  [1]=> array(2) {
[0]=>  string(2) "wj"
[1]=>  array(1) { ["mm"]=> int(9) }
  }
}

结论：
1. count来判断层级

$l = count($template->smarty->_tag_stack);

2. 0为名称，1为参数数据

$template->smarty的属性如下：

$template的属性如下：

function smarty_block_syant($params, $content, &$template, &$repeat) {
foreach($template as $k=>$v){
if(is_object($v)){
echo $k." => ".get_class($v)."\r\n";}
else if(is_array($v)){
echo $k." => "." array "."\r\n";
}else{
echo $k." = ".$v."\r\n";
}
}
}

复制代码

_objType = 2
smarty => Smarty
source => Smarty_Template_Source
inheritance =
template_resource = t.tpl
mustCompile =
templateId = C:\Apache24\htdocs\rb\templates\#file:t.tpl###0
scope = 0
isRenderingCache =
startRenderCallbacks =>  array
endRenderCallbacks =>  array
cache_id =

compile_check = 1
cache_lifetime = 3600

_cache =>  array
template_class = Smarty_Internal_Template

$template->tpl_vars 和$template->smarty->tpl_vars两者分析!

$smarty->smarty->tpl_vars的内容：

array(2) {
  ["name"]=>
  object(Smarty_Variable)#4 (2) {
["value"]=>
string(9) "刘二狗"
["nocache"]=>
bool(false)
  }
  ["sex"]=>
  object(Smarty_Variable)#5 (2) {
["value"]=>
string(3) "man"
["nocache"]=>
bool(false)
  }
}

$smarty->tpl_vars的内容：

array(3) {
  ["SCRIPT_NAME"]=>
  object(Smarty_Variable)#3 (2) {
["value"]=>
string(9) "/rb/t.php"
["nocache"]=>
bool(false)
  }
  ["name"]=>
  object(Smarty_Variable)#4 (2) {
["value"]=>
string(9) "刘二狗"
["nocache"]=>
bool(false)
  }
  ["sex"]=>
  object(Smarty_Variable)#5 (2) {
["value"]=>
string(3) "man"
["nocache"]=>
bool(false)
  }
}

结论是两个的内容是不同的！

$template->_cache和$template->smarty->_cache两者分析!

var_dump($smarty->_cache);
array(0) {
}

var_dump($smarty->smarty->_cache);
array(3) {

  array(1) {
["file"]=>
object(Smarty_Internal_Resource_File)#8 (3) {
   ["uncompiled"]=>

  }

  }
  ["_tag_stack"]=>
  array(1) {
[0]=>
array(2) {
   [0]=>
   string(5) "syant"
   [1]=>
   array(2) {
      ["aa"]=>
      int(1)
      ["bb"]=>
      int(2)
