Smarty Template engine built-in function usage, smarty template engine functions

In this paper, we describe the use of smarty built-in functions. Share to everyone for your reference. Specific as follows:

In-build (built-in), in the Smarty template, provides a lot of built-in function libraries, specific use can refer to Smarty Chinese manual CHM version.

1.foreach function

The operation array is as follows:

Indexed array $res =array (' Shanghai ', ' Beijing ', ' Shenzhen '), $smarty->assign ("arr", $res);//associative array $res 2=array (' city1 ' = ' Beijing ', ' city2 ' = > ' guangzhou ', ' city3 ' = ' Hunan ', $smarty->assign ("arr2", $res 2);//Index two-dimensional array $res 3 = Array (   ' Xiao ', ' Changshan ', ' Wu Bei '), Array (' Shan Shan ', ' keep your '); $smarty->assign ("Arr3", $res 3);//Associative two-dimensional array $res 4 = array (' id ' = ' = '   001 ', ' name ' = ' = ') Zhang San ', ' email ' = ' zhangsan@1163.com '),   array (' url ' = ' http://www.baidu.com ', ' age ' = ') '); $smarty Assign ("Arr4", $res 4);//Associative two-dimensional array 2 $res 5=array ('   emp1 ' =>array (' id ' = ' 001 ', ' name ' = = ' Zhang San ', ' email ' = = ') Zhangsan@1163.com '),   ' emp2 ' =>array (' url ' = ' http://www.baidu.com ', ' age ' = ' 28 ')); $smarty->assign ("Arr5", $res 5);

To iterate over an array:

Where from, item, key is a fixed notation, key can be added according to demand

One-dimensional arrays

Indexed arrays:

<{foreach from= $arr item=temp}>  <{$temp}> 
 
  
Associative arrays:
<{foreach from= $arr 2 item=temp key=k}>  <{$k}>=<{$temp}>
 
  

Note: From, item, key is fixed
Two-dimensional arrays

Two-dimensional indexed arrays:
<{foreach from= $arr 3 item=temp key=k}>  <{* Here temp is an array *}> <{foreach from=   $temp item=val}>     <{$val}>   
Two-dimensional associative array format 1:
<{foreach from= $arr 4 item=temp}>   <{* The outer key is not required, so do not add key*}> <{foreach   from= $temp item=val key=k} >    <{* inner layer key needs, add key*}>     <{$k}>=<{$val}>   
Two-dimensional associative array format 2:
<{foreach from= $arr 5 item=temp key=k}>  <{$k}>:   <{foreach from= $temp item=val key=k2}>    <{$k 2}>=<{$val}>  <{/foreach}>   
<{/foreach}>

2.if...else ...

<{if $age >10}>   age is greater than 10, age: <{$age}>   <{else}>   age less than 10, age: <{$age}> <{/ If}>

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

The known data sources are as follows:

$res 4 = array (' id ' = ' = '   001 ', ' age ' = ' 4 '), array (' id ' = ' = '   002 ', ' age ' = ' + '),   array (' ID ') = ' 003 ', ' age ' = ' + '),   array (' id ' = ' 004 ', ' age ' = ' 80 '));

The references in the template are as follows:

<{foreach from= $arr 4 item=temp}>  <{if $temp. Age < 5}>    <{$temp. Id}>, you are a child  <{ ElseIf $temp. Age >=5 and $temp. Age <= 18}>    <{$temp. Id}> you are young  <{elseif $temp. Age > $t Emp.age <= 50}>    <{$temp id}> you are an adult  <{else}>    <{$temp. id}>   <{/if}><{/foreach}
