Using the Smarty template, Smarty class files in the Libs directory, the Libs directory is copied to the current directory of the workspace, set up templates and Templates_c folders, can also be specified by the code, the system default directory is recommended.

Require_once (".. /smarty-3.1.15/libs/smarty.class.php ");

$smarty =new Smarty;

$smarty->left_delimiter= "<{"; Set smarty variable left tag, default = {

$smarty->right_delimiter= "}>"; Set smarty variable right tag, default to}

assigning variables

$smarty->assign ("title", "title");

Read the assigned content in the template <{title}>

An array in the program

$arr 5=array (

"Emp1" =>array ("id" = "001", "name" = "Xiaoming", "age" = "19"),

"EMP2" =>array ("id" = "002", "name" = "Daming", "Age" = "15")

);

$smarty->assign ("Arr5", $arr 5);

Array reads in templates

<{$arr 5.emp1.name}>

Objects in the program

Class dog{

var $name;

var $age;

var $color;

function __construct ($name, $age, $color) {

$this->name= $name;

$this->age= $age;

$this->color= $color;

}

}

$dog 1=new Dog ("Xiao Duo", "5", "Red");

$smarty->assign ("Dog1", $dog 1);

Object Reading in Templates

<{$dog 1->name}>

Configuration file config/my.conf

Title= "My first configuration file";

Bgcolor= "Pink";

Read the configuration file in the template

Two-dimensional subscript array in the program

$arr 3=array (

Array ("Hebei", "Jilin", "Zhongzhou"),

Array ("Fortuna", "sa-halogen", "Becqing")

);

The template iterates through the data in the two-dimensional array, where key is the subscript index, and the outer temp represents a one-dimensional array, and item represents the contents of the elements in the array

{foreach from= $arr 3 item=temp key=k}

{foreach from= $temp item=val}

{$val}

{/foreach}

{/foreach}

Smarty Direct Fetch value

<{$smarty. get.username}>//directly get the value of username from Get mode

<{$smarty. server.server_name}>//get the IP server name

Registering a custom function

function test ($args) {

$str = "";

for ($i =0; $i < $args [' time ']; $i + +) {

$str. = "<font size=". $args [' Size ']

."‘ Color= '. $args [' Color ']. "' > "

. $args [' content ']. "." </font> ";

}

return $str;

}

Registration function

$smarty->registerplugin ("function", "HSP", "test");

Calling a custom function in a template

{HSP time= "4" size= "5" content= "Custom Function call" Color= "Blue"}

Registering a custom block

function Test2 ($args, $con) {

$str = "";

for ($i =0; $i < $args [' time ']; $i + +) {

$str. = "<font size=". $args [' Size ']

."‘ Color= '. $args [' Color ']. "' > "

. $con. " "." </font> ";

}

return $str;

}

$smarty->registerplugin ("block", "Blk", "test2");

Calling blocks in a template

{BLK time= "4" size= "5" color= "Blue"}

Call test for Blocks

{/BLK}

Smarty Plugin, Smarty plugin in libs/plugins/directory

The format of the function plug-in is function.hlp.php, the block name block.blk.php, which is functions. php,block. Block name. php

The format of the program code in the file is

Smarty_function_hlp ($args,& $smarty) {} or block name Smarty_block_blk ($args, $con,& $smarty)

& $smarty is the necessary format, $con is the content of the closed tag in the template

Variable adjuster, connection string cat, first letter capital capitalize

{$varname | cat: "YEZ": "Second" | capitalize}//connect first Letter and capitalize

{$eshtml |escape}//HTML output in plain text

Regulator plug-in modifer.xxx.php, program function named Smarty_modifer_xxx ($string)

Verify that the mailbox format is a legitimate regulator

<?php

function Smarty_modifier_isemail ($STR) {

$pattern = "/^[a-za-z_][a-za-z0-9_-]*@[a-za-z0-9]+ (\.[ a-za-z0-9]+) +$/i ";

if (Preg_match ($pattern, $str) ==1) {

Return "is a valid format";

}else{

Return "Invalid mailbox format";

}

}

?>

Using in templates

<{$varname | isemail}>

Preg_match ($pattern, $str, $arrs);//The resulting result is a one-dimensional array

Preg_match_all ($pattern, $str, $arrs);//The result is a two-dimensional array

{include file= "BOTTOM.TPL" varname= "value passed"}

The value passed in {$varname} in Bottom.tpl

$smarty->caching=true;//Open Cache

$smarty->cache_lifetime=60;//Set cache time to 60 seconds

$smarty->debugging=true;//Open the Debug Console control window

Local code updates in real time

function Insert_mytime () {return date ("y-m-d h:i:s");}

Use {Insert Name=mytime} in the template

Set a numbered cache

$smarty->display ("Test.tpl", "11");//Set cache with number 11

$smarty->clearallcache ();//Delete all caches

$smarty->clearcache ("Test.tpl", "11");//delete the cache of the specified number
