Use Smarty 3 in PHP: reserved variable in Smarty

There are some reserved variables in Smarty, which can be directly used without being assigned by a PHP script, that is, $ _ tpl-& gt; assign (& amp; #39; var & amp; #39;, & amp; #39; value & amp; #39. 1. variable {$ smarty. get. user} $ _...

 

In Smarty, there are some reserved variables that can be directly used without being assigned by a PHP script, that is, $ _ tpl-> assign ('var', 'value') is not used ') distribute.

1. variables used to access the page request in the template

 

{$ Smarty. get. user }== _ GET ['user']

{$ Smarty. post. user }== _ POST ['user']

{$ Smarty. cookie. username }== _ COOKIE ['username']

{$ Smarty. session. username }== _ SESSION ['username']

{$ Smarty. server. REMOTE_ADDR }== _ SERVER ["REMOTE_ADDR"]

{$ Smarty. env. PATH }== _ ENV ['path']

{$ Smarty. request. username }== _ REQUEST ['username']

 

2. access the constants and system constants defined in the PHP script in the template file.

 

{$ Smarty. const. _ FILE __} current PHP FILE

{$ Smarty. const. CONST_VAR} accesses the constant defined by define in the PHP script.

 

3. get the time of the current server in the template file

 

{$ Smarty. now | date_format: "% Y-% m-% d % H: % M: % S" }== date ('Y-m-d H: I: s ', time ())

 

4. access the configuration file in the template

You can use {$ smarty. config. configuration variable} to access the Template variables in the configuration file. In this way, there are two methods to access the variables in the configuration file in the Template: 1. {# configuration variable #}; 2. {$ smarty. config. configuration variable}. this is also true if there is a region.

 

 

5. obtain the data captured by the Smarty built-in function capture.

The capture function captures the data output from the template and stores the data in a variable instead of outputting the data to the page, any data between {capture name = "foo"} and {/capture} is stored in the variable $ foo, which is specified by the name attribute. Access the variable through $ smarty. capture. foo in the template. if the name attribute is not specified, the function uses "default" as the parameter by default.
