All the accesses to Smarty are variable-based. The following describes how to use an instance.
Example: The main file introduces the template Initialization Configuration File (init. inc. php) and a class, and assigns values to the variables in the template.
First, set the init. inc. php file as the initialization configuration file of the Smarty template.
Init. inc. php
<? Php
Define ('root _ path', dirname (_ FILE _); // defines the website ROOT directory
Require ROOT_PATH. '/libs/Smarty. class. php'; // load the Smarty File
$ _ Tpl = new Smarty (); // instantiate an object
$ _ Tpl-> template_dir = ROOT_PATH. '/tpl/'; // reset the template directory to the tpl directory under the root directory.
$ _ Tpl-> compile_dir = ROOT_PATH. './com/'; // reset the compilation directory to the com directory under the root directory.
$ _ Tpl-> left_delimiter = '<{'; // reset the left delimiter to '<{'
$ _ Tpl-> right_delimiter = '}>'; // reset the left delimiter to '}>'
?>
Index. php of the main file
<? Php
Require 'init. inc. php'; // introduce the template Initialization File
Require 'persion. class. php'; // load the object file
Global $ _ tpl;
$ Title = 'this is a title! ';
$ Content = 'this is body content! ';
/*
* 1. Allocate template variables from PHP;
* Dynamic data (PHP variables generated from databases, files, and algorithms)
* Any type of data can be allocated from PHP, including the following:
* Scalar: string, int, double, boolean
* Combination: array and object
* NULL
* Index arrays are directly accessed through indexes.
* Join an array. Instead of using [join subscript], use the. submark method.
* Objects are directly accessed through->.
**/
$ _ Tpl-> assign ('title', $ title );
$ _ Tpl-> assign ('content', $ content); // variable assignment
$ _ Tpl-> assign ('ar1', array ('abc', 'def', 'ghi'); // assign values to the Index array
$ _ Tpl-> assign ('arr2 ', array ('abc', 'def', 'ghi'), array ('jkl', 'mno ', 'pqr '); // index the value of a two-dimensional array
$ _ Tpl-> assign ('arr3 ', array ('one' => '123', 'two' => '123 ', 'Three '=> '123'); // assign values to the correlated Array
$ _ Tpl-> assign ('arr4 ', array ('one' => '000000', 'two' => '000000 '), 'two' => array ('Three '=> '20140901', 'four' => '20160901'); // associate the values of two-dimensional arrays.
$ _ Tpl-> assign ('arr5 ', array ('one' => array ('000000', '000000'), array ('Three' => '000000 ', '20140901'); // assign values to the joined and indexed hybrid Arrays
$ _ Tpl-> assign ('object', new Persion ('xiaoyi', 10); // assign values to objects
// The value in Smarty can also be calculated (+-*/^ ......)
$ _ Tpl-> assign ('num1', 10 );
$ _ Tpl-> assign ('num2', 20 );
$ _ Tpl-> display ('index. tpl ');
