Smarty 变量调节器

变量调节器主要应用于变量，还有自定义函数和字符串。使用”|”符号和调节器名称应用调节器。参数由”:”符号分开。

Example1.  capitalize 首字大写

Variable_Modifiers.php

include ("../libs/Smarty.class.php");

$smarty = new Smarty();

$smarty->reInitSmarty("../demo/templates","../demo/templates_c","../demo/configs");

$string = "ni hao!";

$smarty->assign("cap",$string);

$smarty->display("variable_modifiers.tpl");

Variable_modifiers.tpl

Capitalize功能演示：<br>

原变量内容：<{$cap}><br>

应用后内容：<{$cap|capitalize}><br>

Example2.  Count_characters 字符计数

Variable_Modifiers.php

include ("../libs/Smarty.class.php");

$smarty = new Smarty();

$smarty->reInitSmarty("../demo/templates","../demo/templates_c","../demo/configs");

$string = "ni hao!";

$smarty->assign("cap",$string);

$smarty->display("variable_modifiers.tpl");

Variable_modifiers.tpl

count_characters功能演示:<br>

<{$cap}>的字符个数为（不计空格）：<{$cap|count_characters}><br>

<{$cap}>的字符个数为（计空格）：<{$cap|count_characters:true}><br>

Example3.  cat 字符串连接

Variable_Modifiers.php

include ("../libs/Smarty.class.php");

$smarty = new Smarty();

$smarty->reInitSmarty("../demo/templates","../demo/templates_c","../demo/configs");

$string = "ni hao!";

$smarty->assign("cap",$string);

$smarty->display("variable_modifiers.tpl");

Variable_modifiers.tpl

cat功能演示：<br>

给字符串<{$cap}>连接***之后：<{$cap|cat:"***"}><br>

Example4.  count_paragraphs 计算段数

Variable_Modifiers.php

include ("../libs/Smarty.class.php");

$smarty = new Smarty();

$smarty->reInitSmarty("../demo/templates","../demo/templates_c","../demo/configs");

$string = "ni hao!\nnihaoma?";

$smarty->assign("cap",$string);

$smarty->display("variable_modifiers.tpl");

Variable_modifiers.tpl

count_paragraphs功能演示:<br>

<{$cap}>的段落个数为：<{$cap|count_paragraphs}>

Example5.  count_sentences 计算句数

<{$cap}>的段落个数为：<{$cap|count_sentences}>

Example6.  count_words 计算词数

<{$cap}>的段落个数为：<{$cap|count_words}>

Example7.  date_format 日期格式*************

利用date_format格式化当前系统日期、时间：<br>

当前系统时间为：<{$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}>

Example8.  string_format 字符串格式化

<{*string_format格式参数:%d(十进制整数) %x(十六进制整数) %o(八进制整数) %u(无符号数显示)*}>

<{$num}>通过%md格式化:<{$num|string_format:"%10d"}><br>

<{$num}>通过%m.nf格式化一个实数：<{$num|string_format:"%.2f"}><br>

<{$num}>能过%e格式化一个实数：<{$num|string_format:"%.2e"}><br>

Example9.  escape 编码

<{$cap|escape:"htmlall"|nl2br}>
