Smarty function---plugin

1) Built-in functions sysplugins are not allowed to be modified

2) Custom functions plugins can be modified

1. capture captures a piece of content but does not output it

Syntax:

{capture name=‘var’}

Contents

{/capture}

Name: Save the content to the specified variable

{$smarty.capture.var}

In templates, if a large amount of content needs to be output repeatedly, you can consider using capture to capture.

2. config_load Load the configuration file

{config_load file="file" section="section"}

file: configuration file name

section: Which configuration section is referenced? Optional parameters

Quotation syntax:

{#var#}

{$smarty.config.var}

3. foreach, foreachelse are used to traverse arrays

Syntax:

{foreach from=array key=key name=name item=content}

{foreachelse} When the array to be traversed does not have any elements, execute the statement following foreachelse

{/foreach}

From: Array to be traversed

Item: traversed key value

Key: The traversed key name

Name: Name the foreach statement

Foreach built-in variables

$smarty.foreach.name.index: Index starts from 0

$smarty.foreach.name.iteration : Index starts from 1

$smarty.foreach.name.first: This value is true when the loop is executed for the first time

$smarty.foreach.name.last: This value is true when the loop is executed for the last time

$smarty.foreach.name.total: Total number of loops

4. include references another template file

{include file="file" assign="var" [var ...]}

File: Template file to be imported

Assign: Save the result, but do not output it this time

[var …]: Optional parameter, passed to the template file

5. include_php Contains a php file

{ include_php file="file" assign="var" once="true|false"}

File: php file to be imported

Assign: Save the output result, but do not output it this time

Once: Whether it only contains once true: yes false: no

This function is available in smarty2.6, but it will be removed in 3.0. If you still want to use this function, you can reference the SmartyBC.class.php class file

6. insert In the template, execute a php function

Syntax:

{ insert name="func" [var ...] }

Name: The name of the php function being called

[var ...]: Specify parameters when calling the function Optional parameters

Insert and include_php are the same. They are all functions in 2.6. In 3.0, this function is placed in the file SmartyBC.class.php.

Note: The name of the php function referenced by insert must be prefixed with insert_

7. if elseif else

{if}

{elseif}

{else}

{/if}

8. The escape character of { } in ldelim and rdelim templates

{ldelim}

{rdelim}
