Smarty Template engine built-in function usage

This article mainly introduces the Smarty template engine built-in function usage, the example analysis of smarty in the foreach function, if...else ..., if...elseif...elseif...else ... such as the use of built-in functions, with a certain reference value, the need for friends can refer to the following

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:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21st 22 23

Indexed array $res =array (' Shanghai ', ' Beijing ', ' Shenzhen '); $smarty->assign ("arr", $res); Associative arrays $res 2=array (' city1 ' = ' Beijing ', ' city2 ' and ' Guangzhou ', ' City3 ' and ' Hunan '); $smarty->assign ("arr2", $res 2); Indexed two-dimensional arrays $res 3 = Array ( Array (' Xiao Hsiao ', ' Changshan ', ' Wu Bei '), Array (' Sunshine ', ' Keep your ') ); $smarty->assign ("Arr3", $res 3); Associative two-dimensional arrays $res 4 = Array ( Array (' id ' = ' 001 ', ' name ' = ' Zhang San ', ' email ' = ' zhangsan@1163.com '), Array (' url ' = = ' http://www.baidu.com ', ' age ' = ' 28 ') ); $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:

?

1 2 3 4 5 6 7 8 9

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

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

?

1 2 3 4 5 6 7 8 9 13 /p> + / / / / / + +

Two-dimensional indexed arrays: <{foreach from= $arr 3 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= $arr 4 item=temp}> <{* the outer key is not required, so do not add key*}> <{foreach from= $temp item=val key=k}> <{* the inner layer of the key needs, add key*}> <{$k}>=<{$val}> <{/foreach}> <{/foreach}> 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 ...

?

1 2 3 4 5

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

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

The known data sources are as follows:

?

1 2 3 4 5 6

$res 4 = Array ( Array (' id ' = ' 001 ', ' age ' = ' 4 '), Array (' id ' = ' 002 ', ' age ' = ' 16 '), Array (' id ' = ' 003 ', ' age ' = ' 20 '), Array (' id ' = ' 004 ', ' age ' = ' 80 ') );

The references in the template are as follows:

?

1 2 3 4 5 6 7 8 9 10 11

<{foreach from= $arr 4 item=temp}> <{if $temp. Age < 5}> <{$temp. Id}> you're a child. <{elseif $temp. Age >=5 and $temp. <= 18}> <{$temp. Id}> you're a young man. <{elseif $temp. Age > $temp. Age <= 50}> <{$temp. Id}> you're an adult. <{else}> <{$temp. Id}> <{/if}> <{/foreach}

I hope this article is helpful to everyone's PHP programming.
