One: Define the use of functions and blocks in PHP files

mysmarty.php

<?php/** * * * All of the following use variables are based on the prefix and suffix set <!--{}--> * * 1. In smarty, use the function * * 2 in the form of custom tags (similar to HTML tags). Use
 Smarty Function * 2.1 Single line tag *//smarty2 in PHP * $tpl->register_function ("Hello", "say");
 *//smarty3 Way * $tpl->registerplugin ("function", "Hello", "say");
 * <!--{Hello size=5 color= "green" content= "22222" num=5}--> * 2.2 Block Mark * PHP *//smarty2 Way
 * $tpl->register_block ("World", "test");
 *//smarty3 Way * $tpl->registerplugin ("Block", "World", "test"); * <!--{World size=8 color= "Red" num=4}--> * world<!--{$title}--><br> * <!--{/
 world}--> * 3 Value * php * $tpl->assign ("title", $title);
 * $TPL->assign ("Color", "pink");
 * $tpl->assign ("content", "content"); * Template (if the associative array needs to use the 1 side of the inverted quotation mark to say) The associated variable contains to be parsed first * you can use $color and $content * <!--{Hello size=5 color= $color content= in the page $co Ntent "num=5}--> * <!--{Hello size=5 color= $color contenT= "' $arr. One '" num=5}--> * * * * * * * *///If the file fails to load require will stop parsing PHP and the include will continue to execute require ' init.smarty.php ';
	
	$title = "This is a text title";
	$tpl->assign ("title", $title);
	$TPL->assign ("Color", "pink");
	$tpl->assign ("content", "content");
	
	$tpl->assign ("arr", Array ("One" => "arr"));
Register a line function//smarty2 the way//$tpl->register_function ("Hello", "say");
	$tpl->register_block ("World", "test");
	Smarty3 Way $tpl->registerplugin ("function", "Hello", "say");
	
	Registration block $TPL->registerplugin ("Blocks", "World", "test");
		/** * Defines a function that parameters are placed in an array of label properties * @param pass parameters $args/function Say ($args) {$html = ""; For ($i =0 $i < $args [num]; $i + +) {$html. = ' <font size= ' > '. $args [' size ']. ' color= '. $args [' Color ']. > '. $args ["Content"]. "
		</font><br> ";
	return $html;
	/** * Definition block, parameters to place label properties * @param pass Parameters $args * @param pass content $content * @param reserved reference variable $a * @param reserved Reference variable $b * *
		function test ($args, $content,& $a,& $b) {$html = ""; for ($i =0; $i < $args ["num"]; $i + +) {$html. = ' <font size= ' > '. $args [' size ']. ' color= '. $args [' Color ']. ' " > '. $content. "
		</font><br> ";
	return $html; //template file name can be arbitrarily defined: For example: MYSMARTY.TPL only content is HTML can be $tpl->display ("mysmarty.html");?>

Mysmarty.html

<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://www.w3.org/TR/html4/loose.dtd" >
 

Two: Add a new file definition function and block in the Smarty Plugin folder plugins

mysmarty.php


<?php
/**
 * 
 * * All use variables below are based on the prefix and suffix <!--{}--> *
 functions
 Write functions using * * 
 plug-in form
 * 	In the Plugins folder, you define a representation function that starts with a function 	: function.hello.php's functions name Smarty_function_hello ($args, $smarty)
 * 	block at the beginning of blocks: block.world.php function name Smarty_block_world ($args, $content,& $smarty)
 * * 
 * 		
 *
	//If the file fails to load require will stop parsing PHP, and include will continue to execute
	require ' init.smarty.php ';
	$title = "This is a text title";
	
	$tpl->assign ("title", $title);
	$TPL->assign ("Color", "pink");
	$tpl->assign ("content", "content");
	$tpl->assign ("arr", Array ("One" => "arr"));
	
	
	
	Template file name can be arbitrarily defined: For example: MYSMARTY2.TPL only content is HTML can be
	$tpl->display ("mysmarty2.html");
>
 

Mysmarty.html


<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://www.w3.org/TR/html4/loose.dtd" >
 

Under plugins in the Smarty Plugins folder:

function.hello.php (note naming rules)


<?php

	/**
	 * Defines a function that parameters are placed in an array of label properties
	 * @param passing parameters $args
	/function Smarty_function_hello ($args, & $smarty) {
		$html = "";
		For ($i =0 $i < $args [num]; $i + +) {
			$html. = ' <font size= ' > '. $args [' size ']. ' color= '. $args [' Color ']. > '. $args ["Content"]. " </font><br> ";
		}
		return $html;
	>
 

block.world.php (note naming rules)


<?php

	/**
	 * definition block, parameter array label attribute
	 * @param passing Parameters $args
	 * @param passing content $content
	 * @param reserved reference variables $a c17/>* @param reserved Reference variable $b
	/function Smarty_block_world ($args, $content,& $smarty) {
		$html = "";
		For ($i =0 $i < $args [num]; $i + +) {
			$html. = ' <font size= ' > '. $args [' size ']. ' color= '. $args [' Color ']. > '. $content. " </font><br> ";
		}
		return $html;
