smarty3中block的研究

zhgc

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：

1.     // 只在结束标签时输出
   
2.     if(!$repeat){
   
3.         if (isset($content)) {
   
4.             $lang = $params['lang'];
   
5.             // 翻译$content的内容
   
6.             return $translation;
   
7.         }
   
8.     }

$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

1.         function smarty_block_nagomenu($params, $content, &$smarty, &$repeat) {
   
2.                  // Smarty_Internal_Template
   
3.                 trigger_error(get_class($smarty), E_USER_NOTICE);
   
4.                  // MySmarty
   
5.                 trigger_error(get_class($smarty->smarty), E_USER_NOTICE);
   
6.         }

复制代码

2. 研究_tag_stack对象

加入以下代码

1.         function smarty_block_syant($params, $content, &$smarty, &$repeat) {
   
2.                 echo $content;
   
3.                 var_dump($smarty->smarty->_tag_stack);
   
4.         }

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：

1. function smarty_block_syant($params, $content, &$template, &$repeat) {
   
2.         foreach($template as $k=>$v){
   
3.                 if(is_object($v)){
   
4.                 echo $k." => ".get_class($v)."\r\n";}
   
5.                 else if(is_array($v)){
   
6.                         echo $k." => "." array  "."\r\n";
   
7.                 }else{
   
8.                         echo $k." = ".$v."\r\n";
   
9.                 }       
   
10.         }
    
11. }

$template->tpl_vars 和$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！

var_dump($smarty->_cache);
