The example of this article describes how to use the configuration file of PHP template engine Smarty in template variables. Share it with everyone for your reference, the details are as follows:

The role of the configuration file in the template is to define variables for the front-end design page, which mainly controls the appearance of the template and has nothing to do with the PHP program.

Usage steps:

1. Use $tpl->configs_dir="directory" //Specify the directory where the configuration file is stored;

2 . Use <{configs_load file="config file"}> in the template to load the f configuration file. If there is an area, you can use section="area" to specify the area.

The purpose of setting the area is : Call configuration file variables in different areas for different files.
In the configuration file, the region is specified through "[region name]". Other variables that do not specify the region are common variables, that is, every page can be used.

3. Create a configuration file in the specified directory.

The following is demonstrated through an example. The example idea: the main file index.php calls the template file index.tpl, and sets the configuration file variables in index.tpl (independent of the PHP program)

init.inc.php Smart template engine initialization file

<?php
  define(&#39;ROOT_PATH&#39;, dirname(__FILE__)); //网站根目录
  require ROOT_PATH.&#39;/libs/Smarty.class.php&#39;; //引入 Smart 模板引擎
  $_tpl = new Smarty(); //初始化一个对象
  $_tpl->template_dir = ROOT_PATH.&#39;/tpl/&#39;; //重新设置网站的模板目录
  $_tpl->compile_dir = ROOT_PATH.&#39;./com/&#39;; //重新设置网站的编译文件目录
  $_tpl->config_dir = ROOT_PATH.&#39;/configs/&#39;; //重新设置网站的配置文件目录
  $_tpl->left_delimiter = &#39;<{&#39;; //重新设置网站的左定界符
  $_tpl->right_delimiter = &#39;}>&#39;; //重新设置网站的右定界符
?>

Copy after login

index.php

<?php
  require &#39;init.inc.php&#39;; //引入模板初始化文件
  global $_tpl;
  $_tpl->display(&#39;index.tpl&#39;); //载入模板文件
?>

Copy after login

index.tpl There are two ways to use configuration variables:
1. <{#Configuration Variables#}>;
2. <{$smart .config.Configuration variables}>

<{config_load file="view.conf" section="one"}>
<!-- view.conf文件不能写完整路径，因为在初始化文件中已经指定,section="one" 代表加载[one]区域 -->
