注释和变量的使用smarty.html

<!DOCTYPE html>
<html lang="en"head>
    meta charset="UTF-8"title>Title</bodyh2>
        <!-- 模板注释被*星号包围，而两边的星号又被定界符包围 -->
        {*$username*}
        {$username}
    h3 变量 
        {$age}
    hr 索引数组 
        arr1:
        {$arr1[1]}
     关联数组 
        arr2:
        {$arr2['username']}
        {$arr2.username}
     对象 
        Object:
        {var_dump($obj->getTemplateDir())}
     变量的运算 
        {$var = 100}
        {$var}
        {$foo = $var + 200}
        {$foo}
    >
        {$foo}
     保留变量的使用 
        $_GET:
        {var_dump($smarty.get)}
    
        $_POST:
        {var_dump($smarty.post)}
    
        $_REQUEST:
        {var_dump($smarty.request)}
    
        COOKIE:
        {var_dump($smarty.cookies)}
    
        SESSION:
        {var_dump($smarty.session)}
    
        SERVER:
        {var_dump($smarty.server)}
    
        ENV:
        {var_dump($smarty.env)}
    
        {time()}
        {$smarty.now}
     加载配置文件后，配置文件中的变量需要用两个井号“#”包围或者是 smarty的保留变量$smarty.config.来调用 
        {config_load file='base.conf'}
        {#FONT_SIZE#}
        {$smarty.config.FONT_COLOR}

流程控制的使用loop.html

>流程控制>
     使用{if}处理分支结构 
    {$number = 200}
    {if $number === 100}
        gt
    {else if $number == 200}
        This number is 200
    {else}
        This number is not 100
    {/if}

    {$bool = false}
    {if not $bool}
        not
    {/if}

    {if $number is not even}
        odd
    {/if}

    {if $number is not odd}
        even
    {/if}

    {if $number mod 2 == 0}
        even
    {/if}

    {if $number is not odd by 3}
        odd
    {/if}

     使用{for}处理循环 
    {for $i = 5 to 4 step 2}
        {$i}
    {forelse}
        no loop
    {/for}

     使用{while}处理循环 
    {while $number > 195}
        {$number--}
    {/while}

     使用{foreach}遍历数组 
    {foreach $arr2 as $key => $val}
        {if $val@first}
            {*break*}
            {continue}
        {/if}
        {$key}:{$val}
        {$val@key}
        {$val@index}
        {$val@iteration}
        {$val@first}
        {$val@last}
        {$val@show}
        {$val@total}
    {foreachelse}
        data does not exist
    {/foreach}

     使用{section}遍历数组 
    {section name=key loop=$arr1}
        {$arr1[key]}
    {/section}

    {section name=key loop=$users2 step=-1 max=2}
        id: {$users[key].id}
        username: {$users[key].username}
        age: {$users[key].age}
        {$smarty.section.key.index}
        {$smarty.section.key.iteration}
        {$smarty.section.key.rownum}
        {$smarty.section.key.index_prev}
        {$smarty.section.key.index_next}
    {sectionelse}
        no loop
    {/section}

常用标签函数的使用single_tag_func.html

>常用标签函数的使用
    {assign var="name" value="Jason"}
    {assign "name" "Jason Lee"}
    {$name}

    {append var="arr1" value=4 index="3"}
    {var_dump($arr1)}

    {ldelim}$name{rdelim}

    {html_checkboxes name="hobby" values=$hobby_ids output=$hobby_output selected=$hobby_ids}
    {html_checkboxes name="hobby" options=$options selected=$hobby_ids}
    {html_image width="50" height="50" alt="Google" href="http://www.google.com" file="https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png"}
    {html_options name="hobby" values=$hobby_ids output=$hobby_output selected=2}
    {html_options name="hobby" options=$options selected=2}
    {html_radios name="hobby" options=$options selected=2}
    {html_select_date}
    {html_select_time}
    {html_table loop=$arr1 cols=2 rows=3}
    {mailto address="86267659@qq.com" subject="test" text="给我发邮件" cc="123123@qq.com"}
    {math equation="x + y" x = 100 y = 200}
