Iv. custom functions for Smarty templates

Custom functions for Smarty templates (common in this article)

Divided into three categories:

1. Variable Adjuster

2. Functions

3. Block function

Usage of three kinds of plugins:

1, the use of variable mediators,

< {$var|myfun:arg1:arg2} >

2. Function usage (much like using HTML tags)

Such as

<colorsizenum= "7"}>

The functions defined in PHP are:

$smarty->registerplugin ("function", "Myfun","one"); function One ($args,$smarty) {}   //$args color= "Red" size= "7" num= "7" These parameters are combined with an associative array, and the second parameter is automatically received by the $smarty object, if not written

3, the use of block functions,

Such as

<colorsize= "7"}> content <{/myfun  }>

The functions defined in PHP are:

$smarty->registerplugin ("block", "Myfun","I")Function ($args ,$content,$smarty) {}   //$args An associative array that combines these parameters for color= "Red" size= "7", The second parameter is the "content" to be displayed, and the third parameter is the $smarty object

There are two ways of doing this:

1. Use the Registerplugin () method in the Smarty object to register functions in PHP as functions in Smarty.

2, is the development of the Smarty plug-in (to separate specific files to add plug-ins)

1) Location of the Declaration

Can be created in the original plugins directory in the Smarty class library, or you can use the directory $smarty->addpluginsdir (directory) you specified//smarty3

2) Name of the file

modifier, modifier. Modifier name. php

Functions, functions. Name of the function. php

Block function, block function name. php

3) Naming of functions

modifier, Smarty_modifier_ modifier name ()

function, Smarty_function_ function name ()

Block function, Smarty_block_ block function name ()

4) Rules for parameters

modifier, smarty_modifier_ modifier name ($var, $arg 1, $arg 2, $arg 3)

function, Smarty_function_ function name ($args, $smarty)

Block function, Smarty_block_ block function ($args, $content, $smarty, $repeat)

$repeat parameter prevents the block function from being called repeatedly, and the first call is true and later false

<{myfun color= "Red" size= "7"}> content <{/myfun}> First Myfun true, second <{/myfun}> false
