Reserved variable usage analysis in PHP template engine smarty, template Smarty


This example describes the usage of reserved variables in the PHP template engine smarty. Share to everyone for your reference, as follows:

In Smarty, there are reserved variables that are not required to be allocated by the PHP script and can be used directly, i.e. without using $_tpl->assign (' var ', ' value ') to allocate.

1. Accessing the page request variables 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. Accessing the constants and system constants defined in the PHP script in the template file

{$smarty. const.__file__}  Currently executing PHP file {$smarty. Const.const_var}  //Access define defined constants in PHP scripts

3. Get the current server time in the template file

Copy the code as follows: {$smarty. Now|date_format: "%y-%m-%d%h:%m:%s"} = = date in php script (' y-m-d h:i:s ', Time ())

4. configuration file access in the template

You can access the template variables in the configuration file by {$smarty. config. Configuration variable}. In this case, there are two ways to access the variables in the configuration file in the template: one, {#配置变量 #}, two, {$smarty. config, config variable}, if there is a region.

5. Get data captured by Smarty built-in function capture

The function of the capture function is to capture data from the template output and store it in a variable instead of outputting it to the page, and any data between {capture Name= "foo"} and {/capture} will be stored in the variable $foo, which is specified by the Name property. The variable is accessed by the $smarty. Capture.foo in the template, and if the Name property is not specified, the function defaults to use "default" as the parameter.
