1. Introduction to zhimeng template parsing Engine
Before learning about the template code of DedeCms, it is very meaningful to know about the zhimeng template engine. The zhimeng template engine is a template parser that uses XML Namespaces. The biggest advantage of using the zhimeng parser to parse templates is that you can easily define tag attributes, like using HTML, the template code is very intuitive and flexible. The new zhimeng template engine can not only parse templates, but also analyze error tags in templates.
1. The Code style of the zhimeng template engine is as follows:
{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}
Tip:
For a tag in the form of {dede: Tag Name attribute = 'value'} {/dede: Tag name}, in version 2.1, "{/dede}" is used to end the process,
"{/Dede: Tag name}" must be strictly used in V3; otherwise, an error will be reported.
2. The zhimeng template engine has multiple built-in system tags that can be directly used in any scenario.
(1) The global flag indicates obtaining an external variable. In addition to the Database Password, it can call any configuration parameters of the system in the form:
{Dede: global name = 'variable name'} {/dede: global}
Or
{Dede: global name = 'variable name '/}
The variable name cannot contain the $ symbol. For example, the variable $ inclu_cmspath 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 paths for files are in the absolute path, include folder, CMS installation directory, and CMS main template directory.
3. The woven dream mark allows the function to process the obtained value in any tag, in the form:
{Dede: Tag Name attribute = 'value' function = 'youfunction ("parameter 1", "parameter 2", "@ me ")'/}
@ Me indicates the value of the current tag. Other parameters are determined by your function. For example:
{Dede: field name = 'pubdate' function = 'strftime ("% Y-% m-% d % H: % M: % S", "@ me ") '/}
Ii. DedeCms template creation specifications
1. DedeCms's main template is placed in the "DedeCms installation directory/templets" directory. system is the underlying template, which can be changed in "Custom style template (InnerText, the default folder is the default template officially provided by DedeCms. Because the DedeCms minimum system contains four templates: Gallery, article, Flash, and download. With the templates for topics, searches, and home pages, there are a total of sixteen basic template files, you can change the template as needed.
2. DedeCms template tags are divided into cover template tags (channel cover, home page), list template tags, document template tags, and special purpose tags by function.
Iii. Reference
1. arclist flag
This tag is the most commonly used tag in DedeCms. Among them, hotart, coolart, likeart, artlist, imglist, imginfolist, and specart are all extended by the different attributes defined by this tag.
Purpose: obtain a list of specified documents.
Applicability: Cover templates, list templates, and document templates
(1) Basic Syntax:
{Dede: arclist
Typeid = ''row = ''col = ''titlelen =''
Infolen = ''imgwidth = ''imgheight = ''listtype = ''orderby = ''keyword = ''}
Custom style template (InnerText)
{/Dede: arclist}
This tag is equivalent to artlist, imglist, and imginfolist. It is exactly the same as artlist, and is different from imglist and imginfolist, which are only the default underlying templates.
(2) attribute reference:
[1] typeid = ''indicates the topic ID. You do not need to specify the topic ID in the list template or archive template. You can specify multiple columns separately in the cover template;
[2] row = ''indicates the number of returned documents;
[3] col = ''indicates the number of columns to be displayed (Single Column by default );
[4] titlelen = ''indicates the title length;
[5] infolen = ''indicates the content description length;
[6] imgwidth = ''indicates the width of the thumbnail;
[7] imgheight = ''indicates the height of the thumbnail;
[8] type = ''indicates the file type. The default value or type = 'all' indicates a common document.
§ Type = 'spec 'indicates the topic document, which is equivalent
{Dede: specart typeid = ''row ='' col = ''titlelen ='' infolen =''
Imgwidth = ''imgheight = ''listtype = ''keyword = ''} {/dede: specart}
§ Type = 'commend' indicates the recommendation document, which is equivalent
{Dede: coolart typeid = ''row ='' col = ''titlelen ='' infolen =''
Imgwidth = ''imgheight = ''listtype = ''keyword = ''} {/dede: coolart}
§ Type = 'image' indicates a document that must contain a thumbnail.
§ Type = 'number', specific channel type, 1 Article, 2 image sets, 3 software, 4 Flash, other numbers are the id of the User-Defined channel, that is, the value of dede_channeltype.ID.
[9] orderby = ''indicates the sorting method. The default value is senddate. Property with the same name: sort
§ Orderby = 'hot 'or orderby = 'click' indicates the order. This attribute is equivalent
{Dede: hotart typeid = ''row ='' col = ''titlelen ='' infolen =''
Imgwidth = ''imgheight = ''listtype = ''keyword = ''} {/dede: hotart}
§ Orderby = 'pubdate' is arranged by publishing time (that is, the time value that can be changed at the front end)
§ Orderby = 'sortrank' sort by the new sorting level of the article (use this attribute if you want to use the top article)
§ Orderby = 'id' sort by Article id
[10] keyword = ''indicates the list of documents containing the specified keyword. Separate multiple keywords.
(3) underlying template Variables
ID (same id), title, iscommend, color, typeid, ismake, description (same as info ),

Arcurl (same as filename), typeurl, stime (pubdate in the "0000-00-00" format ),
Textlink, typelink, imglink, image
Where:
Textlink = title
Typelink = typename
Imglink =
Image =
Variable call method: [field: varname/]

The position is a link in the form of "column 1> Column 2", and the title is the title in this form.
