Basic syntax:

{* Comment content *}

Example code:

2, Smarty the variables in 1) variables allocated from PHP (normal variables, arrays, objects )

Basic syntax:

$smarty->assign ();

Example code:

demo02.php

Demo02.html

Operating effect:

2 ) to read the variable from the configuration file

Basic syntax:

In the HTML static template page, you can invoke the following method:

{config_load file= ' config file name '}

{#配置文件中的标签名称 #}

Example code:

The effect is as follows:

3) Create in template file

Basic syntax:

Defined

{Assign var= ' name ' value= ' value '}

{$name = ' Zhangsan '}

Call

{$name}

Example code:

The effect is as follows:

3. reserved variables in the Smarty

$smarty. Get.page equivalent to $_get[' page ')

$smarty. Post.page equivalent to $_post[' page ')

$smarty. Cookies.username $_cookies[' username ']

$smarty. Server.server_name $SERVER [' server_name ']

$smarty. Env.path gets the path path to the environment variable in the system

$smarty. Session.id $_session[' id ']

$smarty. Request.username $_request[' username ']

{$smarty. Now}: Gets the current system time

{$smarty. Const}: Get Constants in PHP

{$smarty. Capture}: Get capture tag captured content

{$smarty. config}: Read configuration file information {$smarty. Config.title}

{$smarty. Section}: Get section loop information

{$smarty. Template}: Gets the static template name of the current call

{$smarty. Current_dir}: Gets the current path

{$smarty. Version}: Gets the version number of the current Smarty

{$smarty. Ldelim} = {Ldelim}: Gets the left delimiter in the current Smarty

{$smarty. Rdelim} = {Rdelim}: Gets the right delimiter in the current Smarty

Example code:

Demo03.html

Operating effect:

4. Variables Regulator ( variable formatting tool) 1) What is a variable adjuster

A: variable adjuster is mainly to format the variable

Basic syntax:

{variable | regulator: Parameter 1: Parameter 2: ...} 2 ) commonly used variable conditioners

{$var |capitalize}: Capitalize first letter

{$var |count_characters:true}: Calculates the length of a character, the second argument is true: Calculates a space

{$var |count_paragraphs}: Count the number of paragraphs

{$var |count_sentences}: Calculating the number of sentences

{$var |count_words}: Number of words calculated

{$var |cat:var2}: Connection string

{$var |date_format: "%y%m%d"}: Time formatting Y year m D Day h hour m minute s seconds

{$var |default: ' Value '}: Set default value

{$var |escape}: transcoding, mainly for HTML code

{$var |indent:10: "*"}: Character indent

{$var |lower}: Convert to lowercase

{$var |nl2br}: Convert \ n to BR label

{$var |regex_replace: "/[\t\n]/": ""}: Regular replacement

{$var |replace: "AA": "BB"}: Character substitution

{$var |spacify: "^^"}: intervening spaces (between characters and characters intervening spaces)

{$var |string_format: '%d '}: String formatting%s formatted as String%d to Integer

{$var |strip: "*"}: Remove extra spaces

{$var |strip_tags}: Removing HTML tags

{$var |truncate:30: "..."}: Intercept characters

{$var |upper}: Convert to Uppercase

{$var |wordwrap:30: "<br>"}: Line width constraint (only how many characters can be displayed per line)

Example code:

Example 1:

Example 2:

Example 3:

Example 4:

5. Variables Regulator Combination Application

{$var |capitalize|truncate:30: "..." |replace: "AA": "BB"}

A: Capitalize the first letter and intercept 30 characters and use ... and replace the AA in the string with BB 6, built-in function 1)capture

Basic syntax

{Capture name= ' var '}

Content

{/capture}

{$smarty. Capture.var}

Function: Captures a piece of content but does not output this time

Example code:

Operating effect:

2) Config_load

Basic syntax

{config_load file= ' profile name ' section= ' section '}

{#变量名称 #}

{$smarty. config. Variable name}

Example code:

Operating effect:

3) foreach

Basic syntax:

Foreach,foreachelse

{foreach from= array

key= Key

Name= Name

item= content}

{Foreachelse}

{/foreach}

Function: Implements the traversal output of an array (similar to foreach)

Parameter description:

From: Array to traverse

Item: The system automatically saves the traversed results to the item option each time it is traversed

Name: Name the Foreach Loop

Key: Keys for saving loops

Foreachelse: When the array to be traversed is empty, the system enters the current statement segment

Example 1: Traversing a one-dimensional array

Sample code

Effect:

Example 2: Two-dimensional array traversal

Example 3: Use of key value key

Example 4:foreachelse

Description: When the array is empty, the system automatically turns to the Foreachelse statement

Additional Properties in foreach

$smarty. Foreach.name.index @index Get the current loop index

$smarty. Foreach.name.iteration @iteration The first cycles (iterations)

$smarty. Foreach.name.first @first when the first loop, the condition is true

$smarty. Foreach.name.last @last when the last loop, the condition is true

$smarty. foreach.name.total @total total number of times to get loops

Example 5: Parameter name demo

The effect is as follows:

Example 6: Achieving an interlaced color effect

Example code:

Operating effect:

4) Include

Basic syntax

{include file= "to include the template file name" assign= "var" [var ...]}

Features: Include template files

Parameter description:

File: The name of the template files to include

Variable name = form of variable value

Schematic diagram:

For our project: because the head and tail of the project are mostly the same, so we can separate the whole project, we just need to do the middle part.

Example code:

Operating effect:

5) include_php

Basic syntax:

{include_php file= "php file path" Once=true}

Features: Introduction of external PHP files

Once: The specified number of citations is 1, boolean,true: The current file can only be introduced once, the default is True

Note: This label is deprecated in smarty3.0 and can be used if you want to use the Smarty2 portal file

6. Insert

Basic syntax

{Insert Name= ' function name ' variable = value of variable}

Function: allows us to introduce PHP functions directly on the Smarty template page

Example code:

demo10.php Code

demo10.html Code

Note: When using the Insert method, be aware that the function you create must precede the Insert_ prefix, and that the passed arguments are appended to the function's formal parameters as an array.

Job: Complete the paging program via Php+smarty
