1. Overview of the DedeCms template parsing engine Before understanding the template code of DedeCms, it is very meaningful to understand the knowledge of the DedeCms template engine. The Dreamweaver template engine is a template parser that uses XML namespaces. The biggest advantage of using the Dreamweaver parser to parse templates is that you can easily specify the attributes of the tag. It feels like using HTML, making the template code very intuitive. Flexible, the new version of the Dreamweaver template engine can not only parse the template but also analyze the wrong tags in the template.

1. The code styles of the Dreamweaver template engine have the following forms:
{dede: tag name attribute = 'value'/}
{dede: tag name attribute = 'value'} {/dede: tag name}
{dede: tag name attribute = 'value'} Custom style template (InnerText) {/dede: tag name}

Tips:
For {dede: Tag name attribute = 'value'} {/dede: tag name} In version 2.1, only "{/dede}" is needed to indicate the end, but in
V3, "{/ dede:mark name}", otherwise an error will be reported.

2. The DreamWeaver template engine has multiple built-in system tags, which can be used directly in any situation.

(1) global tag, which means to obtain an external variable. In addition to the database password, any configuration parameters of the system can be called. The form is:
{dede:global name='variable name'}{ /dede:global}
or
{dede:global name='variable name' /}

The variable name cannot be added with the $ symbol, such as the variable $cfg_cmspath, which should be written as {dede:global name ='cfg_cmspath' /}.

(2) foreach is used to output an array, in the form:
{dede:foreach array='array name'}[field:key/] [field:value/]{/dede:foreach }

(3) include introduces a file in the form:
{dede:include file='file name' /}
The search path for files is in the order: absolute path, include file folder, CMS installation directory, CMS main template directory

3. The Dreamweaver tag allows the use of functions in any tag to process the obtained value, in the form:
{dede: tag name attribute = 'value ' function='youfunction("Parameter 1", "Parameter 2", "@me")'/}
where @me is used to represent the value of the current tag, and other parameters are determined by your function. For example:
{dede:field name='pubdate' function='strftime("%Y-%m-%d %H:%M:%S","@me")' /}

2. DedeCms template production specifications

The templates of the DedeCms system are not fixed. Users can choose the column template when creating a new column. The official only provides the most basic default template, which is each of the built-in system models. Template, DedeCms supports custom channel models. After users customize a new channel model, they need to design a new template according to the model.
1. Concept, design and use of templates, you must understand the following concepts:
1. Section (cover) template:
Refers to the template used for the homepage of the website or the cover of the more important columns, generally using " index_identification ID.htm". In addition, a single page or custom tag defined by the user can also choose whether to support section template tags. If supported, the system will use the section template tag engine to parse before outputting the content or generating a specific file.
2. List template:
It refers to the template of the list of all articles in a certain column of the website, generally named with "list_identification ID.htm".
3. File template:
Represents the template of the document viewing page, generally named with "article_identification ID.htm".
4. Other templates:
The general system generally includes templates: home page template, search template, RSS, JS compilation function template, etc. In addition, users can also customize a template to create any file.
2. Naming. For the sake of standardization, DreamWeaver officially recommends using a unified way to name templates, as follows:
1. Template saving location:
Template directory: {cmspath/templets/style name (English) , the default is default, where system is the underlying template of the system, plus is the template used by the plug-in)/specific function template file｝
General template location: "/templets/default"
2. Template file naming convention:
(1) index_identification ID.htm: represents the section (column cover) template;
(2) list_identification ID.htm: represents the column list template;
(3) article_identification ID.htm : Indicates content viewing page (document template, including topic viewing page);
(4) search.htm: Search results list template;
(5) index.htm: Home page template;
Note:
The [identification IDs] of each content channel in your system are:
Example: list_image.htm means that it is the default list template for columns whose content type is picture collection.
