Usage of built-in functions of smarty template engine, smarty template engine functions

This article describes how to use smarty built-in functions. Share it with everyone for your reference. The details are as follows:

In-build (built-in), in the smarty template, many built-in function libraries are provided. For specific usage, please refer to the chm version of the smarty Chinese manual.

1.foreach function

The operand array is as follows:

//索引数组 
$res=array('上海','北京','深圳');
$smarty->assign("arr",$res);
//关联数组 
$res2=array('city1'=>'北京','city2'=>'广州','city3'=>'湖南');
$smarty->assign("arr2",$res2);
//索引二维数组 
$res3 = array( 
  array('潇晓','常山','吴蓓'),array('珊珊','常明') 
);
$smarty->assign("arr3",$res3);
//关联二维数组 
$res4 = array( 
  array('id'=>'001','name'=>'张三','email'=>'zhangsan@1163.com'), 
  array('url'=>'http://www.baidu.com','age'=>'28') 
);
$smarty->assign("arr4",$res4);
//关联二维数组2 
$res5=array( 
  'emp1'=>array('id'=>'001','name'=>'张三','email'=>'zhangsan@1163.com'), 
  'emp2'=>array('url'=>'http://www.baidu.com','age'=>'28') 
); 
$smarty->assign("arr5",$res5);

Traverse the array:

Among them, from, item, and key are fixed writing methods, and key can be added according to needs

One-dimensional array

Index array:

<br/> 
<{foreach from=$arr item=temp}>
  <{$temp}> <t/> 
<{/foreach}> 
<br/>关联数组:<br/> 
<{foreach from=$arr2 item=temp key=k}>
  <{$k}>=<{$temp}><t/>
<{/foreach}> 
<br/>

Note: from, item, key are fixed
Two-dimensional array

<br/>二维索引数组:<br/> 
<{foreach from=$arr3 item=temp key=k}>
  <{*这里的temp是一个数组*}> 
  <{foreach from=$temp item=val}> 
    <{$val}> 
  <{/foreach}> 
<{/foreach}> 
<br/>二维关联数组格式1：<br/> 
<{foreach from=$arr4 item=temp}> 
  <{*外层的键不需要，所以不添加key*}> 
  <{foreach from=$temp item=val key=k}>
    <{*内层的键需要，添加key*}> 
    <{$k}>=<{$val}> 
  <{/foreach}> 
<{/foreach}> 
<br/>二维关联数组格式2：<br/> 
<{foreach from=$arr5 item=temp key=k}>
  <{$k}>: 
  <{foreach from=$temp item=val key=k2}>
    <{$k2}>=<{$val }>
  <{/foreach}> 
  <br/> 
<{/foreach}>

2.if...else...

<{if $age>10 }> 
  年龄大于10，年龄为：<{$age}> 
  <{else}> 
  年龄小于10，年龄为：<{$age}> 
<{/if}>

3.if...elseif...elseif...else...

The known data sources are as follows:

$res4 = array( 
  array('id'=>'001','age'=>'4'), 
  array('id'=>'002','age'=>'16'), 
  array('id'=>'003','age'=>'20'), 
  array('id'=>'004','age'=>'80') 
);

The template is quoted as follows:

<{foreach from=$arr4 item=temp }>
  <{if $temp.age < 5}>
    <{$temp.id}>,你是小孩
  <{elseif $temp.age >=5 and $temp.age <= 18}>
    <{$temp.id}>,你是年轻人
  <{elseif $temp.age > 18 and $temp.age <= 50}>
    <{$temp.id}>,你是成年人
  <{else}>
    <{$temp.id}>,年龄<span style="font-family:Consolas;">比较大了</span>
  <{/if}>
<{/foreach}
