Overview of parsing engine Template design specification Code reference Mark reference: arclist(artlist,likeart,hotart,imglist,imginfolist,coolart,specart) field channel mytag vote friendlink mynews loop channelartlist page list pagelist pagebreak fieldlist 1. Dreamweaver template parsing engine Overview Before understanding the template code of DedeCms, it is very meaningful to understand the knowledge of the DreamWeaver 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 1", "Parameter 2", "@me") '/} where @me is used to represent 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")' /} 2. DedeCms template production specifications The template of the DedeCms system is not fixed. Users can choose the column template when creating a new column. The official only provides The most basic default template is each template of the built-in system model. 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 website homepage or the cover of more important columns, generally using "index_identification ID.htm "Name. In addition, users can choose whether to support section template tags for individual pages or custom tags individually defined. 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: 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: Represents the content viewing page (document template, including topic viewing page); (4) search.htm: Search results list template; (5) index.htm: Home page template; Notes: The [identification IDs] of each content channel in your system are: Example: list_image.htm means yes, yes The default list template for columns whose content type is picture collection. 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 Scope of application: cover template, list template, document template (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, 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 archive templates. In the cover template, "," is allowed to represent multiple columns separately; [2] row='' means the number of rows in the returned document. If used in combination with col, the result number is equal to row * col; [3] col='' means how many columns to display (default is single column); [4] titlelen=' ' represents the length of the title; [5] infolen='' represents the length of the content introduction; [6] imgwidth='' represents the width of the thumbnail; [7] imgheight='' represents the height of the thumbnail; [8] type= '' indicates the file type, where the default value or type='all' is an ordinary document. § type='commend' indicates a recommended document, which is equivalent to § type='image', which indicates that a thumbnail image must be included. Document [9] orderby='' indicates the sorting method. The default value is senddate arranged by release time. § orderby='hot' or orderby='click' means sorting by the number of clicks § orderby='pubdate' sorting by publication time (that is, the time value that the front desk allows to change) § orderby='sortrank' sorting by the newness of the article Sorting level sorting (use this attribute if you want to use pinned articles) § orderby='id' Sort by article ID [10] keyword='' represents a list of documents containing specified keywords, multiple keywords use ", "Separate [11] channelid='number' indicates a specific channel type, built-in channels: topic (-1), article (1), gallery (2), Flash (4), software (3) [12 ] limit='start, end' indicates a limited record range. The row attribute must be equal to "end - start". MySQL's limit statement starts from 0. For example, "limit 0,5" means taking the first five records. Records, "limit 5,5" means starting from the fifth record, take down five records. (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 = titletypelink = typename imglink = image = Variable calling method: [field:varname / ] For example: {dede:arclist infolen='100'} [field:textlink /]
