First, the 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
DEDECMS system template is non-fixed, users can create a new column can choose their own column template, the official only provide the most basic default template, that is, the built-in system model of the various templates, DEDECMS support the custom channel model, after the user to customize the new channel model, you need to design a new set of templates according to the model.
First, the concept, design and use of templates, must understand the following several concepts:
1, plate (cover) Template:
Refers to the website homepage or the more important section cover use template, generally uses "Index_ recognizes id.htm" The name, moreover, the user individual definition individual page or the custom mark, also may choose whether supports the plate template mark, if supports, The system will use the plate template tag engine to parse and then output the content or generate a specific file.
2. List template:
A template that refers to the list of all articles in a section of a website, usually named "List_ recognition id.htm".
3. File Template:
A template that represents a document viewing page, typically named "Article_ recognition id.htm".
4. Other templates:
General system general includes templates include: Homepage template, search template, rss, JS compile function template, etc., in addition, users can also customize a template to create any file.
Second, naming, for the sake of standardization, weaving dream official recommended to use a unified way to name the template, as follows:
1. Template Save Location:
Template directory: {cmspath/templets/style name (default, the system is the underlying template, plus the template used by the plugin)/specific feature template file}
General template location: "/templets/default"
2. template file naming specification:
(1) index_ identification id.htm: Represents the plate (column cover) template;
(2) List_ recognition id.htm: Indicates the column list template;
(3) Article_ recognition id.htm: Indicates content viewing page (document template, including thematic view page);
(4) Search.htm: Search result list template;
(5) Index.htm: homepage template;
Annotations:
Your system's [identification ID] for each content channel is:
Example: list_image.htm is the default list template for a column of content type picture set.
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 rows returned to the document, if combined with COL, the result number is equal to row * COL;
[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;
