I. Weaving dream template parsing engine overview
Before you know the template code for DEDECMS, it makes sense to know the knowledge of the dream templating engine. Weaving dream template engine is a template parser using XML namespace form, the biggest advantage of using the Dream Parser parsing template is that it can easily make the attributes of the tag, it feels like HTML, so that the template code is very intuitive and flexible, The new version of the Weaving Dream template engine not only enables the parsing of templates but also analyzes the errors in the template.
1, Weaving Dream template Engine Code style has 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} This form of markup, in version 2.1, indicates that the end requires only "{/dede}", but
V3 need to strictly use "{/dede: Tag name}", otherwise it will be an error.
2, weaving Dream template engine built-in multiple system tags, these system markings can be used in any situation directly.
(1) Global tag, which means to get an external variable, in addition to the database password, can invoke any configuration parameters of the system, in the form of:
{dede:global name= ' variable name '} {/dede:global}
Or
{dede:global name= ' variable name '/}
Where variable names cannot be added to the $ symbol, such as variables $cfg _cmspath, should be written as {Dede:global name= ' Cfg_cmspath '/}.
(2) foreach is used to output an array in the form of:
{dede:foreach array= ' array name '} [field:key/] [field:value/] {/dede:foreach}
(3) include introduces a file in the form of:
{dede:include file= ' file name '/}
The search path to the file is in order: Absolute path, include folder, CMS installation directory, CMS master template directory
3. The dream tag allows a function to be used in any tag to process the resulting 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, other parameters are determined by your function for existence, for example:
{Dede:field name= ' pubdate ' function= ' strftime ("%y-%m-%d%h:%m:%s", "@me") '/}
Second, Dedecms template production specifications
1, Dedecms's main template is placed in the "Dedecms installation directory/templets" directory, where system is the underlying template, can generally be changed in the "Custom style template (InnerText)", default The folder is the default template that Dedecms officially provides. Because the Dedecms smallest system contains atlas, articles, Flash, download 4 large templates, plus the theme, search and home page templates, there are 16 basic template files, you can change the template as you want.
2. Dedecms template tags are categorized by function: Cover page template tags (channel cover, home page), list template tags, document template tags, and special purpose tags.
Third, the main marker reference
1. Arclist Mark
This tag is the most commonly used marker for dedecms, where Hotart, Coolart, Likeart, Artlist, Imglist, Imginfolist, and Specart are all extended by the different attributes defined by the tag.
Function: Gets a list of specified documents
Scope of application: Cover page template, list template, document template
(1) Basic syntax:
{Dede:arclist
Typeid= ' row= ' col= ' titlelen= '
infolen= ' imgwidth= ' imgheight= ' listtype= ' orderby= ' keyword= '}
Custom style templates (InnerText)
{/dede:arclist}
This tag is equivalent to the artlist, imglist, imginfolist tags, which are exactly the same as artlist, unlike Imglist and Imginfolist, which are only the default underlying templates.
(2) attribute reference:
[1] typeid= "indicates the column ID, in the list template and profile template generally do not need to specify, in the cover template allows", "separate representation of multiple columns;
[2] row= "indicates the number of documents returned;
[3] col= ' indicates how many columns are displayed (default is single column);
[4] titlelen= ' indicates the title length;
[5] infolen= "indicates the length of the content introduction;
[6] imgwidth= "indicates the width of the thumbnail image;
[7] imgheight= "indicates the height of the thumbnail image;
[8] type= "indicates the file type, where the default value or type= ' all ' is a normal document
§type= ' Spec ', which represents a feature document, is equivalent to
{dede:specart typeid= ' row= ' col= ' titlelen= ' infolen= '
Imgwidth= ' imgheight= ' listtype= ' keyword= '}{/dede:specart}
§type= ' commend ' indicates the recommended document, equivalent to
{dede:coolart typeid= ' row= ' col= ' titlelen= ' infolen= '
Imgwidth= ' imgheight= ' listtype= ' keyword= '}{/dede:coolart}
§type= ' Image ' indicates a document that must contain a thumbnail image
§type= ' numbers ', specific channel types, 1 articles, 2 picture sets, 3 software, 4 Flash, other numbers is the ID of the user-defined channel, which is the value of dede_channeltype.id.
[9] orderby= ' indicates the Sort method, the default value is senddate by release time. Property with the same name: sort
§orderby= ' hot ' or orderby= ' click ' means in order, using this property is equivalent to
{dede:hotart typeid= ' row= ' col= ' titlelen= ' infolen= '
Imgwidth= ' imgheight= ' listtype= ' keyword= '}{/dede:hotart}
§orderby= ' pubdate ' by publication time (that is, the time value that the foreground allows to change)
§orderby= ' Sortrank ' is sorted by the new sort level of the article (use this property if you want to use a pinned article)
§orderby= ' id ' sorted by article ID
[keyword=] Indicates a list of documents containing the specified keywords, with multiple keywords separated by ",".
(3) Underlying template variable

Textlink,typelink,imglink,image
which
Textlink = Title
Typelink = TypeName
Imglink =
