[1]smarty的保留变量问题

来源: 互联网发布时间: 2013-11-30

以下是访问页面请求变量诸如get,post,cookies,server,enviroment和session变量的例子. 例如{$smarty.server.SERVER_NAME}取得服务器变量，{$smarty.env.PATH}取得系统环境变量path, {$smarty.request.username}取得get/post/cookies/server/env的复合变量。
　　{$smarty.now}变量用于访问当前时间戳.
　　可以用 date_format调节器格式化输出. 例如{$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}
　　{$smarty.const}
　　你可以直接访问PHP常量. 例如{$smarty.const._MY_CONST_VAL}
　　{$smarty.capture}
　　可以通过 {capture}..{/capture}结构截取的输出可以使用{$smarty} 变量访问.
　　{$smarty.config}
　　{$smarty}变量可以访问已经加载的config变量.
　　例如 {$smarty.config.foo}就可以表示 {#foo#}.
　　{$smarty.section}, {$smarty.foreach}
　　{$smarty} 变量可以访问'section'和'foreach'循环的属性.
　　{$smarty.template}
　　显示当前被处理的模板的名字.
　　{$smarty.version}
　　显示smarty模板的版本
　　{$smarty.ldelim}
　　显示左分隔符
　　{$smarty.rdelim}
　　显示右分隔符

这里声明一点，上例中不小心把数据库表中lastupd字段错打成lastudp，本例子予以更正。

除上诉字段数据库与上例一致。

工程仍沿用上例，如下图：

代码依次为：

database.php：与上例一致。

companies_controller.php：

<?php

class CompaniesController extends AppController

{

var $name = 'Companies';

function index()

{

$this->set('companies', $this->Company->findAll());

}

function view($id = null)

{

$this->Company->id = $id;

$this->set('company', $this->Company->read());

}

function add()

{

if (!emptyempty($this->data))

{

if ($this->Company->save($this->data))

{

$this->flash('Your post has been saved.','/companies');

}

function edit($id = null)

{

if (emptyempty($this->data))

{

$this->Company->id = $id;

$this->data = $this->Company->read();

}

else

{

if ($this->Company->save($this->data['Company']))

{

$this->flash('Your post has been updated.','/companies');

}

function delete($id)

{

$this->Company->del($id);

$this->flash('The post with id: '.$id.' has been deleted.', '/companies');

}

company.php：

<?php

class Company extends AppModel

{

var $name = 'Company';

var $validate = array(

'company' => VALID_NOT_EMPTY,

'price' => VALID_NOT_EMPTY,

'change' => VALID_NOT_EMPTY,

'lastupd' => VALID_NOT_EMPTY

);

}

index.thtml：

<h1>Test companies</h1>

<table>

<tr>

<th>company</th>

<th>price</th>

<th>change</th>

<th>last update</th>

</tr>

<?php foreach ($companies as $company): ?>

<tr>

<td>

<?php echo $html->link($company['Company']['company'], "/companies/view/".$company['Company']['id']); ?>

<?php echo $html->link('Delete', "/companies/delete/{$company['Company']['id']}", null, 'Are you sure?')?>

</td>

</tr>

<?php endforeach; ?>

</table>

<p>

<?php echo $html->link('add', "/companies/add"); ?>

</p>

view.thtml：

<h1>Company: <?php echo $company['Company']['company']?></h1>

<p>Price: <?php echo $company['Company']['price']?></p>

<p>Change: <?php echo $company['Company']['change']?></p>

<p>LastUpdate: <?php echo $company['Company']['lastupd']?></p>

<br/>

<p>

<?php echo $html->link('edit', "/companies/edit/".$company['Company']['id']); ?>

</p>

add.thtml：

<h1>Add Company</h1>

<p>

Company:

<?php echo $html->input('Company/company', array('size' => '40'))?>

<?php echo $html->tagErrorMsg('Company/company', 'Company is required.') ?>

</p>

<p>

Price:

<?php echo $html->input('Company/price', array('size' => '40'))?>

<?php echo $html->tagErrorMsg('Company/company', 'Price is required.') ?>

</p>

<p>

Change:

<?php echo $html->input('Company/change', array('size' => '40'))?>

<?php echo $html->tagErrorMsg('Company/change', 'Change is required.') ?>

</p>

<p>

Last Update:

<?php echo $html->input('Company/lastupd', array('size' => '40'))?>

<?php echo $html->tagErrorMsg('Company/lastupd', 'Last Update is required.') ?>

</p>

<p>

<?php echo $html->submit('Save') ?> <?php echo $html->link('return', "/companies/index"); ?>

</p>

</form>

edit.thtml：

<h1>Edit Company</h1>

<?php echo $html->hidden('Company/id'); ?>

<p>

Company:

<?php echo $html->input('Company/company', array('size' => '40'))?>

<?php echo $html->tagErrorMsg('Company/company', 'Company is required.') ?>

</p>

<p>

Price:

<?php echo $html->input('Company/price', array('size' => '40'))?>

<?php echo $html->tagErrorMsg('Company/company', 'Price is required.') ?>

</p>

<p>

Change:

<?php echo $html->input('Company/change', array('size' => '40'))?>

<?php echo $html->tagErrorMsg('Company/change', 'Change is required.') ?>

</p>

<p>

Last Update:

<?php echo $html->input('Company/lastupd', array('size' => '40'))?>

<?php echo $html->tagErrorMsg('Company/lastupd', 'Last Update is required.') ?>

</p>

<p>

<?php echo $html->submit('Save') ?> <?php echo $html->link('return', "/companies/index"); ?>

</p>

</form>

如此访问http://localhost/cakephp/companies即可测试代码。

首先建立数据库cake_ext，并执行如下sql文：

CREATE TABLE `companies` (

`id` int(11) NOT NULL auto_increment,

`company` varchar(50) NOT NULL,

`price` decimal(8,2) NOT NULL,

`change` decimal(8,2) NOT NULL,

`lastudp` date NOT NULL,

PRIMARY KEY (`id`)

) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;

-- ----------------------------

-- Records

-- ----------------------------

INSERT INTO `companies` VALUES ('1', '3m Co', '71.72', '0.02', '2008-10-21');

INSERT INTO `companies` VALUES ('2', 'Alcoa Inc', '29.01', '0.42', '2008-10-20');

INSERT INTO `companies` VALUES ('3', 'AT&T Inc.', '31.61', '-0.48', '2008-10-21');

INSERT INTO `companies` VALUES ('4', 'Boeing Co.', '75.43', '0.53', '2008-10-13');

INSERT INTO `companies` VALUES ('5', 'United Technologies Corporation', '63.26', '0.55', '2008-10-09');

INSERT INTO `companies` VALUES ('6', 'Intel Corporation', '19.88', '0.31', '2008-10-15');

INSERT INTO `companies` VALUES ('7', 'Exxon Mobil Corp', '68.10', '-0.43', '2008-10-17');

如下图所示建立工程：

数据库配置文件如下：

class DATABASE_CONFIG

{

var $default = array('driver' => 'mysql',

'connect' => 'mysql_connect',

'host' => 'localhost',

'login' => 'root',

'password' => 'root',

'database' => 'cake_ext',

'prefix' => '');

var $test = array('driver' => 'mysql',

'connect' => 'mysql_connect',

'host' => 'localhost',

'login' => 'root',

'password' => 'root',

'database' => 'cake_ext',

'prefix' => '');

}

companies_controller.php：

<?php

class CompaniesController extends AppController

{

var $name = 'Companies';

function index()

{

$this->set('companies', $this->Company->findAll());

}

function view($id = null)

{

$this->Company->id = $id;

$this->set('company', $this->Company->read());

}

company.php：

<?php

class Company extends AppModel

{

var $name = 'Company';

}

index.thtml：

<h1>Test companies</h1>

<table>

<tr>

<th>company</th>

<th>price</th>

<th>change</th>

<th>last update</th>

</tr>

<?php foreach ($companies as $company): ?>

<tr>

<td>

<?php echo $html->link($company['Company']['company'], "/companies/view/".$company['Company']['id']); ?>

</td>

</tr>

<?php endforeach; ?>

</table>

view.thtml：

<h1>Company: <?php echo $company['Company']['company']?></h1>

<p>Price: <?php echo $company['Company']['price']?></p>

<p>Change: <?php echo $company['Company']['change']?></p>

<p>LastUpdate: <?php echo $company['Company']['lastudp']?></p>

访问http://localhost/cakephp/companies即可运行测试程序。
