核心文件
include/dedetemplate.class.php
功能描述
用于非核心模块的动态页面或列表页的模板解析, 如:member/content_list.php ,通常是在 datalistcp.class.php 中使用,这个类在动态运行的情况下,由于本身是把模板编译成PHP的,因此性能上会优级于旧的解析类,这个方法将在未来版本中作为通用的方式。
使用方法
<button title="Copy Code" class="copy" style="touch-action: manipulation; border: 1px solid var(--vp-code-copy-code-border-color); padding: 0px; background-image: var(--vp-icon-copy); direction: ltr; position: absolute; top: 12px; right: 12px; z-index: 3; border-radius: 4px; width: 40px; height: 40px; opacity: 0; background-position: 50% center; background-size: 20px; background-repeat: no-repeat; transition: border-color 0.25s, background-color 0.25s, opacity 0.25s;"></button>
php$tpl = new DedeTemplate(
模板对象实例名称,通常是'tpl',
[模板存放目录(生成缓存时会存放在这个目录),
include语法默认引用目录]
);

通常情况下参数二和参数三是不必要的,如:
<button title="Copy Code" class="copy" style="touch-action: manipulation; border: 1px solid var(--vp-code-copy-code-border-color); padding: 0px; background-image: var(--vp-icon-copy); direction: ltr; position: absolute; top: 12px; right: 12px; z-index: 3; border-radius: 4px; width: 40px; height: 40px; opacity: 0; background-position: 50% center; background-size: 20px; background-repeat: no-repeat; transition: border-color 0.25s, background-color 0.25s, opacity 0.25s;"></button>
php$tpl = new DedeTemplate('tpl');

如果在类文件中调用,应该加上设置:
<button title="Copy Code" class="copy" style="touch-action: manipulation; border: 1px solid var(--vp-code-copy-code-border-color); padding: 0px; background-image: var(--vp-icon-copy); direction: ltr; position: absolute; top: 12px; right: 12px; z-index: 3; border-radius: 4px; width: 40px; height: 40px; opacity: 0; background-position: 50% center; background-size: 20px; background-repeat: no-repeat; transition: border-color 0.25s, background-color 0.25s, opacity 0.25s;"></button>
php$this->tpl->SetObject($this);
1
在一些块调用中默认将使用当前类的成员函数。
<button title="Copy Code" class="copy" style="touch-action: manipulation; border: 1px solid var(--vp-code-copy-code-border-color); padding: 0px; background-image: var(--vp-icon-copy); direction: ltr; position: absolute; top: 12px; right: 12px; z-index: 3; border-radius: 4px; width: 40px; height: 40px; opacity: 0; background-position: 50% center; background-size: 20px; background-repeat: no-repeat; transition: border-color 0.25s, background-color 0.25s, opacity 0.25s;"></button>
php$tpl->LoadTemplate(模板的物理路径);
1
如果模板中带有 {dede:config name='' value=''/}
可以在载入模板后,通过 $tpl->GetConfig($name)
获得这些变量的值。
显示页面或保存页面为文件
<button title="Copy Code" class="copy" style="touch-action: manipulation; border: 1px solid var(--vp-code-copy-code-border-color); padding: 0px; background-image: var(--vp-icon-copy); direction: ltr; position: absolute; top: 12px; right: 12px; z-index: 3; border-radius: 4px; width: 40px; height: 40px; opacity: 0; background-position: 50% center; background-size: 20px; background-repeat: no-repeat; transition: border-color 0.25s, background-color 0.25s, opacity 0.25s;"></button>
php$tpl->Display();

<button title="Copy Code" class="copy" style="touch-action: manipulation; border: 1px solid var(--vp-code-copy-code-border-color); padding: 0px; background-image: var(--vp-icon-copy); direction: ltr; position: absolute; top: 12px; right: 12px; z-index: 3; border-radius: 4px; width: 40px; height: 40px; opacity: 0; background-position: 50% center; background-size: 20px; background-repeat: no-repeat; transition: border-color 0.25s, background-color 0.25s, opacity 0.25s;"></button>

系统配置变量,等同于 <?php echo $cfg_name; ?>
考虑到大多数情况下都会在函数或类中调用模板,因此 $_vars
、$fields
数组必须声明为 global
数组,否则模板引擎无法获得它的值从而导致产生错误。
自由调用块标记

必要属性:
- bind - 数据源来源函数
- bindtype - 函数类型,默认是
class
可选为 sub
- rstype - 返回结果类型,默认是
array
,可选项为 string

自定义函数格式必须为 function(array $atts,object $refObj, array $fields);
在没有指定 bind
绑定的函数的情况下,默认指向 MakePublicTag($atts,$tpl->refObj,$fields)
统一管理。

直接用 {else}
表示,但不支持 {else if}
这样的语法 ,一般建议模板中不要使用太复杂的条件语法,如果确实有需要,可以直接使用 php 语法。
