在了解DedeCms的模板代码之前,了解一下织梦模板引擎的知识是非常有意义的。织梦模板引擎是一种使用XML名字空间形式的模板解析器,使用织梦解析器解析模板的最大好处是可以轻松的制定标记的属性,感觉上就像在用HTML一样,使模板代码十分直观灵活,新版的织梦模板引擎不单能实现模板的解析还能分析模板里错误的标记。
1、织梦模板引擎的代码样式有如下几种形式:
{dede:标记名称 属性='值'/}
{dede:标记名称 属性='值'}{/dede:标记名称}
{dede:标记名称 属性='值'}自定义样式模板(InnerText){/dede:标记名称}
提示:
如果使用带底层模板的标记,必须严格用{dede:标记名称 属性='值'}{/dede:标记名称} 这种格式,否则会报错。
2、织梦模板引擎内置有多个系统标记,这些系统标记在任何场合都是能直接使用的。
(1) global 标记,表示获取一个外部变量,除了数据库密码之外,能调用系统的任何配置参数,形式为:
{dede:global name='变量名称'}{/dede:global}
或
{dede:global name='变量名称'/}
其中变量名称不能加 $ 符号,如变量 $cfg_cmspath ,应该写成 {dede:global name='cfg_cmspath'/} 。
(2) foreach 用来输出一个数组,形式为:
{dede:foreach array='数组名称'}[field:key/] [field:value/]{/dede:foreach}
(3) include 引入一个文件,形式为:
{dede:include file='文件名称' ismake='是否为dede板块模板(yes/no)'/}
对文件的搜索路径为顺序为:绝对路径、include文件夹,CMS安装目录,CMS主模板目录
3、织梦标记允许在任何标记中使用函数对得到的值进行处理,形式为:
{dede:标记名称 属性='值' function='youfunction("参数一","参数二","@me")'/}
其中 @me 用于表示当前标记的值,其它参数由你的函数决定是否存在,例如:
{dede:field name='pubdate' function='strftime("%Y-%m-%d %H:%M:%S","@me")'/}
4、织梦标记允许有限的编程扩展。
格式为:
{dede:tagname runphp='yes'} $aaa = @me; @me = "123456"; {/dede:tagname}
@me 表示这个标记本身的值,因此标记内编程是不能使用echo之类的语句的,只能把所有返回值传递给@me。
此外由于程序代码占用了底层模板InnerText的内容,因此需编程的标记只能使用默认的InnerText。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
