标签的数学运算


require('../smarty3/smaty.class.php');
require('../mySmaty.class.php');

$smarty = new MySmarty();

$smarty->assign('age',88);
$smarty->display('jisuan.html');
复制代码

jisuan.html

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>

    <p>标签是可以参与运算的，但是不推荐</p>

    {$age + 10}
    {$age - 10}
    {$age * 10}
    {$age / 10}
    等...
</body>
</html>复制代码

标签的逻辑运算

logical-operation.html

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    {if $status === 1}
        <h2>处方有效</h2>
    {else}
        <h2>处方过期</h2>
    {/if}

    <p>从地址栏里传参</p>

    {if $smarty.get.sex === 0}
        you are a man
    {elseif $smarty.get.sex === 1}
        you are a women
    {else}
        人妖
    {/if}
</body>
</html>复制代码

标签的循环

for,while
foreach,section

section功能多，配置选项多，原理和foreach一样，我们在开发中，用foreach可以满足绝大部分循环情况

for循环


require('../smarty3/smaty.class.php');
require('../mySmaty.class.php');

$smarty = new MySmarty();

// for循环从1到10
$smarty->assign('start',1);
$smarty->assign('end',10);

$smarty->display('loop.html');
复制代码

loop.html

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>

    <pre>
        {literal}
            {for $i = $start to $end}
            {/for}
        {/literal}
        原理是$i的初始值为$start,$i不断增加，直到等于$end
    </pre>


    {for $i = $start to $end step 2}

            {$i}

    {/for}

    $i@total,总循环次数
    $i@iteration,当前循环是第几次
    $i@first,首次循环
    $i@last,最后一次循环

</body>
</html>复制代码

foreach循环

二位数组的循环，如：新闻列表，会员列表，商品列表


require('../smarty3/smaty.class.php');
require('../mySmaty.class.php');

$smarty = new MySmarty();

$goods = array('0'=>array('goods_id'=>'1','goods_name'=>'iPad air2','goods_price'=>'4673'),
    '2'=>array('goods_id'=>'2','goods_name'=>'iPhone5s','goods_price'=>'3300'));

$smarty->assign('goods',$goods);
$smarty->display('demo.html');
复制代码

demo.html

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
        {literal}

            foreach循环数组的典型写法:
            {foreach $source as $itemvar}
            {foreach $arrayvar as $keyvar=>$itemvar}

        {/literal}

    <table>
        <tr><td>序号</td><td>商品名</td><td>价格(元)</td></tr>

        {foreach $goods as $key=>$item}
        <tr><td>{$item.goods_id}</td><td>{$item.goods_name}</td><td>{$item.goods_price}</td></tr>
        </foreach>

    </table>
</body>
</html>复制代码
