Usage of built-in functions of smarty template engine

This article mainly introduces the usage of built-in functions of smarty template engine. It analyzes the foreach function and if... The usage of built-in functions such as else..., if...elseif...elseif...else... and other built-in functions have certain reference value. Friends in need can refer to it

The example in this article describes how to use smarty’s 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);

//Index array $res=array('Shanghai','Beijing','Shenzhen'); $smarty->assign("arr",$res); //Associative array $res2=array('city1'=>'Beijing','city2'=>'Guangzhou','city3'=>'Hunan'); $smarty->assign("arr2",$res2); //Index two-dimensional array $res3 = array( array('Xiaoxiao','Changshan','Wu Bei'), array('Shanshan','Changming') ); $smarty->assign("arr3",$res3); //Associated two-dimensional array $res4 = array( array('id'=>'001','name'=>'Zhang San','email'=>'zhangsan@1163.com'), array('url'=>'http://www.baidu.com','age'=>'28') ); $smarty->assign("arr4",$res4); //Associated two-dimensional array 2 $res5=array( 'emp1'=>array('id'=>'001','name'=>'Zhang San','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: ?

<{foreach from=$arr item=temp}> <{$temp}> <{/foreach}> Associative array: <{foreach from=$arr2 item=temp key=k}> <{$k}>=<{$temp}> <{/foreach}>

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

二维索引数组: <{foreach from=$arr3 item=temp key=k}> <{*这里的temp是一个数组*}> <{foreach from=$temp item=val}> <{$val}> <{/foreach}> <{/foreach}> 二维关联数组格式1： <{foreach from=$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}>=<{$val}> <{/foreach}> <{/foreach}> 二维关联数组格式2： <{foreach from=$arr5 item=temp key=k}> <{$k}>: <{foreach from=$temp item=val key=k2}> <{$k2}>=<{$val }> <{/foreach}> <{/foreach}>

Two-dimensional index array:
<{foreach from=$arr3 item=temp key=k}> <{*temp here is an array*}> <{foreach from=$temp item=val}> <{$val}> <{/foreach}> <{/foreach}>
Two-dimensional associative array format 1:
<{foreach from=$arr4 item=temp}> <{*The outer key is not needed, so no key is added*}> <{foreach from=$temp item=val key=k}> <{*The inner key is required, add key*}> <{$k}>=<{$val}> <{/foreach}> <{/foreach}>
Two-dimensional associative array format 2:
<{foreach from=$arr5 item=temp key=k}> <{$k}>: <{foreach from=$temp item=val key=k2}> <{$k2}>=<{$val }> <{/foreach}>
<{/foreach}>

<{if $age>10 }> Age greater than 10, age: <{$age}> <{else}> If you are less than 10 years old, your age is: <{$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') );
