Thinkphp commonly used built-in tags include the detailed

http://www.php.cn/php/php-tp-historyoutput.html "target=" _blank "> variable output is sufficient to use normal tags, but to complete other control, loop and judgment functions, It is necessary to use the tag library function of the template engine, and all the tags of the system's built-in tag library can be used directly without introducing the tag library.

There are two types of XML tags, including closed tags and open tags, when a label is defined to determine whether it is a closed or open label, not mixed use, for example:

Closing Tags:

<include file= "read"/>

Open Tags:

<GT name= "Name" value= "5" >value</gt>

The list of supported tags and attributes is as follows:

Label Signature	Role	Include property
Include	Include external template file (closed)	File
Import	Import resource file (closed including JS CSS load alias)	File,href,type,value,basepath
Volist	Loop array Data output	Name,id,offset,length,key,mod
Foreach	Array or object traversal output	Name,item,key
For	For loop data output	Name,from,to,before,step
Switch	Branch judgment output	Name
Case	Branch judgment output (must be used with switch)	Value,break
Default	Default output (closed must be used with switch)	No
Compare	Compare outputs (including EQ NEQ lt gt egt Elt Heq Nheq aliases)	Name,value,type
Range	Range judgment output (including in notin between Notbetween aliases)	Name,value,type
Present	Determining whether to assign a value	Name
Notpresent	Determine if a value has not been assigned	Name
Empty	Determine if the data is empty	Name
Notempty	Determine if the data is not empty	Name
Defined	Determine if a constant is defined	Name
notdefined	To determine if a constant is undefined	Name
Define	Constant definition (closed)	Name,value
Assign	Variable assignment (closed)	Name,value
If	Conditional Judgment Output	Condition
ElseIf	Conditional judgment output (closed must be used with if label)	Condition
Else	The condition does not set up the output (closed can be used for other labels)	No
Php	Using PHP code	No

1.include

You can use the include tag to include external template files, using the following methods:

Include tags (including external template files)
Closed	Closed label
Property	File (required): template file to include, support variable

Example:

1. Use the full file name to include

Format:

<include file= "full template file name"/>

For example:

<include file= "./tpl/default/public/header.html"/>

In this case, the template file name must contain a suffix. When using the full file name, it is important to note that the file contains a server-side inclusion, not a URL address, that is, the file parameter is the server-side path, if you use a relative path, it is based on the entry file location of the project.

2. Other action template files containing the current module

Format:

<include file= "Operation name"/>

For example, import the Read action template under the current module:

<include file= "read"/>

The action template does not need to have a suffix.

3. Action template with other modules

Format:

<include file= "module name: Operation name"/>

For example, the header action template that contains the public module:

<include file= "Public:header"/>

4. Module action template with other template themes

Format:

<include file= "theme name: module Name: Action name"/>

For example, the Read action template for the user module that contains the blue theme:

<include file= "Blue:User:read"/>

5. Use variables to control the template to be imported

Format:

<include file= "$ variable name"/>

For example

<include file= "$tplName"/>

assigning different values to $tplname can contain different template files, and the values of the variables are used the same as the previous usage.

Regardless of the way you use the external template, the include tag supports passing in parameters at the same time as the include file, for example, in the following example we passed the title and keywords variables when we included the header template:

<include file= "header" title= "thinkphp framework" keywords= "open source Web development framework"/>

You can use the var1 and VAR2 variables in the included Header.html file, method

Note: Because of the characteristics of template parsing, parsing starts from the portal template, and if the external template changes, the template engine does not recompile the template unless in debug mode or the cache has expired. If the included external template file is modified in deployment mode, the cache directory of the module needs to be emptied, otherwise it will not take effect.
