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 the form {dede: tag name attribute = 'value'} {/dede: tag name} In version 2.1, you only need to use "{/dede}" to indicate the end, but in
V3, you need to strictly use "{/dede:mark name}", otherwise an error will be reported.
2. The Dreamweaver template engine has multiple built-in system tags, and these system tags can be used directly in any situation.
(1) global tag means to obtain an external variable. In addition to the database password, it can call any configuration parameters of the system. 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 introduction A file in the form:
{dede:include file='file name' /}
The search path for the file is in the order: absolute path, include folder, CMS installation directory, CMS main template directory
3. Dreamweaver mark Allows the use of functions in any tag to process the obtained value, in the form:
{dede: tag name attribute = 'value' function = 'youfunction ("parameter one", "parameter two", "@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
1. The main template of DedeCms is placed in the "DedeCms installation directory/templets" directory, where system is the underlying template. Generally, it can be changed in "Custom Style Template (InnerText)". The default folder is the default template officially provided by DedeCms. Because the minimum system of DedeCms includes 4 large templates, including albums, articles, Flash, and downloads, plus topic, search, and homepage templates, there are a total of sixteen basic template files. You can change the templates you need according to your own situation.
2. The template tags of DedeCms are divided by function into: cover template tags (channel cover, home page), list template tags, document template tags and special purpose tags.
3. Main tag reference
1. arclist tag
This tag is the most commonly used tag in DedeCms. Among them, hotart, coolart, likeart, artlist, imglist, imginfolist, and specart are all extended by different attributes defined by this tag. of.
Function: Get a specified document list

{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, The imginfolist tag is completely identical to artlist, and is only different from imglist and imginfolist in the default underlying template.
(2) Attribute reference:
[1] typeid='' represents the column ID, which generally does not need to be specified in list templates and file templates. In the cover template, "," is allowed to separately represent multiple columns;
[2] row='' means the number of documents returned;
[3] col='' means how many columns to display (default is single column);
[4] titlelen='' means the title length;
[5] infolen='' means Content introduction length;
[6] imgwidth='' indicates thumbnail width;
[7] imgheight='' indicates thumbnail height;
[8] type='' indicates file type, where the default value or type='all ' is an ordinary document
§ When type='spec', it means a special document, which is equivalent to
{dede:specart typeid='' row='' col='' titlelen='' infolen=''
imgwidth='' imgheight='' listtype='' keyword=''}{/dede:specart}
§ type='commend' indicates recommended documents, which is equivalent to
{dede:coolart typeid='' row='' col=' ' titlelen='' infolen=''
imgwidth='' imgheight='' listtype='' keyword=''}{/dede:coolart}
§ When type='image', it means that the document must contain thumbnail images
§ type='number', specific channel type, 1 article, 2 photo album, 3 software, 4 Flash, other numbers are user-defined channel id, which is the value of dede_channeltype.ID.
[9] orderby='' indicates the sorting method. The default value is senddate arranged by release time. Attributes with the same name: sort
§ orderby='hot' or orderby='click' means sorting in order. Using this attribute is equivalent to
{dede:hotart typeid='' row='' col='' titlelen='' infolen =''
imgwidth='' imgheight='' listtype='' keyword=''}{/dede:hotart}
§ orderby='pubdate' arranged by publication time (that is, the time value allowed to be changed by the front desk)
§ orderby='sortrank' Sort by the new sorting level of the article (use this attribute if you want to use pinned articles)
§ orderby='id' Sort by article ID
[10] keyword='' indicates documents containing the specified keyword List, multiple keywords are separated by ",".
(3) Bottom template variables
ID (same as id), title, iscommend, color, typeid, ismake, description (same as info),
pubdate, senddate, arcrank, click, litpic (same as picname), typedir, typename,
arcurl (same as filename), typeurl, stime (pubdate's "0000-00-00" format),
textlink, typelink, imglink, image
where:
textlink = title
typelink = typename
imglink =
image =
variable call Method: [field:varname /]
For example:
{dede:arclist infolen='100'}
[field:textlink /]
[field:info /]
{/dede:arclist}
2. Field mark
this Tags are used to obtain field values ​​of specific columns or files and commonly used environment variable values ​​
Applicable scope: cover templates, list templates, document templates

{dede:field name=''/}
(2 ) The value of the name attribute:
Section template: phpurl, indexurl, indexname, templeturl, memberurl, powerby, webname, specurl
List template: position, title, phpurl, templeturl, memberurl, powerby, indexurl, indexname, specurl, column table dede_arctype All fields
where position is a link in the form of "Column One > Column Two", title is a title in this form
Document template: position,phpurl,templeturl,memberurl,powerby,indexurl,indexname,specurl,id( Same as ID, aid), all fields of archive dede_archives table and additional tables.
