Question

如何在smarty中包含.php文件，从Smarty中的搜索输入处理$ _POST数据并在.tpl文件中显示结果？如何在smarty控制器或配置文件中正确定义search.php？我现在是聪明的引擎的初学者，并不知道有关这个引擎的许多事情和技巧 index.php smarty core

<?php
//ob_start('ob_gzhandler');
$t1 = microtime ( 1 );
session_start ();
header ( "Content-Type: text/html; charset=utf-8" );
require_once ("inc/initf.php");
//require_once("/verjani/public_html/inc/search.php");//how to include ?
$smarty = new Smarty ();
// $smarty->debugging = true;
// $smarty->error_reporting = E_ALL & ~E_NOTICE;
$smarty->cache_dir = THEM_PATH . "/cache";
$smarty->template_dir = THEM_PATH . "/template";
$smarty->compile_dir = THEM_PATH . "/template_c";
Helper::register($smarty);
$frontEnd = new frontEnd ();
$module = $frontEnd->getModule ();
$module->viewHeaders ();
if ($module->displayTpl !== false) {
    $smarty->assign ( 'COOKIE', $_COOKIE );
    $smarty->assign ( 'this', $module );
    $smarty->display ( $module->displayTpl, md5 ( $_SERVER ['REQUEST_URI'] ) );
}
$t = microtime();
echo '<!--'.$t.'-->';

来自http://www.smarty.net/docs/en/language.function.foreach.tpl#idp8696576的

search.php

<?php 
  include('Smarty.class.php'); 

  $smarty = new Smarty; 

  $dsn = 'mysql:host=localhost;dbname=test'; 
  $login = 'test'; 
  $passwd = 'test'; 

  // setting PDO to use buffered queries in mysql is 
  // important if you plan on using multiple result cursors 
  // in the template. 

  $db = new PDO($dsn, $login, $passwd, array( 
     PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true)); 

  $res = $db->prepare("select * from users"); 
  $res->execute(); 
  $res->setFetchMode(PDO::FETCH_LAZY); 

  // assign to smarty 
  $smarty->assign('res',$res); 

  $smarty->display('index.tpl');?>
?>

的 header.tpl.html 的

<form method="post" action="../search.php" class="searchform cf">
              <input type="text" placeholder="">
              <button type="submit">Search</button>
</form>

以下是一些指示：

您不必创建多个smarty实例，应该初始化smarty的唯一地方是index.php文件
不要从search.php文件中显示index.tpl文件，index.php文件应该包含自己的TPL文件。相反，让您的search.php文件访问数据库并将结果作为数组返回，并将其分配给一个smarty变量，您可以在搜索到TPL文件时使用该变量来显示结果。

我就是这样做的。

<强>的index.php

<?php
require('smarty-setup.php');

$smarty = new Smarty_Setup(); //must match class created in smarty setup file in order for it to work


require('search.php');

//uncomment these lines for debugging
// $smarty->debugging = true;
// $smarty->error_reporting = E_ALL & ~E_NOTICE;
$smarty->display('test.tpl');

<强>的smarty-setup.php

<?php

// load Smarty library
require('/smarty/Smarty.class.php');


// The setup.php file is a good place to load
// required application library files, and you
// can do that right here. An example:
// require('guestbook/guestbook.lib.php');

class Smarty_Setup extends Smarty {

   function __construct()

   {

        // Class Constructor.
        // These automatically get set with each new instance.
        parent::__construct();


        $this->setTemplateDir('/templates/');
        $this->setCompileDir('/smarty/templates_c/');
        $this->setConfigDir('/smarty/configs/');
        $this->setCacheDir('/smarty/cache/');
   }
}
?>

<强>的search.php

  <?php

  if($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['search'])))
  {

      $ResultsArray = array();
      //conduct your search using $_POST['search'] to get the search
      //query and put the results in the $ResultsArray above.

      $smarty->assign('searchResults', $ResultsArray);
      $smarty->assign('displayForm', 'false');
  } else {

      $smarty->assign('displayForm', 'true');
  }
  ?>

<强>在index.tpl

<!DOCTYPE html>
<html lang="en">
    <body>
        {include file='search.tpl'}
    </body>
</html>

<强> search.tpl

{if $displayForm eq true}
    <form method="post" action="{$smarty.server.SCRIPT_NAME}" class="searchform cf">
          <input type="text" name="search" placeholder="Search" />
          <button type="submit">Search</button>
    </form>

{else}

    <h1>Search Results</h1>
    <ul>
        {foreach from=$searchResults item=result}
            <li>{$result}</li>
        {/foreach}
    </ul>
{/if}

如果你需要它，还有更多信息：

Smarty if statements
Smarty foreach statements

另外，快速说明。您可以创建一个smarty-setup.php文件，您可以像我一样声明您的config，templates，templates_C和caches目录。有关详细信息，请参见此处（http://www.smarty.net/docs/en/installing.smarty.extended.tpl）。

重要提示 此搜索表单不以任何方式保密。它可以用来破解你的网站。为了防止此类攻击，请参阅以下文章：

Securing PHP forms
SQL injection（仅在查询数据库时才有必要）。
