如何智者可變輸出存儲到PHP變量，完成MySQL查詢

Question

我想運行智者模板文件MySQL查詢.......

文件擴展名是

每一件事運行的.html罰款只是我想運行一個查詢是不完整的，沒有smarty變量

例如 $ q1 = mysql_query（「select * from class_users where class = {$ v.user_id}」）;不工作

我想將{$ v.user_id}存儲到php變量中，例如$ var =「{$ v.user_id}」;

<?php 
$connect = mysql_connect("localhost","***","****") or die('error connecting: ' . mysql_error()); 
mysql_select_db("****") or die('error selecting db: ' . mysql_error()); //select database 
?> 

<div class="classified{if $v.highlited && $ads_settings.enable_highlited} highlited{/if} {if $v.featured && $ads_settings.enable_featured} featured{/if}" {if $v.highlited && $ads_settings.enable_highlited}style='background: {$ads_settings.highlited_color};'{/if}> 

{if $v.featured && $ads_settings.enable_featured}<div class="featured-icon"></div>{/if}

Answer 1

您可以在Smarty模板使用{php}標籤embed PHP code。請注意，這是棄用功能，雖然（請參閱鏈接），並可能從未來的版本中刪除。它也破壞了Smarty作爲旨在將演示文稿與應用程序邏輯分離的模板語言的實際目的。

話雖這麼說，如果你仍然想做到這一點，下面可能工作（未經測試，雖然）：

{php} 
$v = $this->getVariable('v'); 
print_r($v['user_id']); 
{/php} 

Answer 2

$ V可能是從渲染模板 使用數據庫的PHP代碼中設置在PHP文件中查詢不在模板文件 中，它們到底是模板文件！
