thinkphp template range Judging output in label and range label Usage _php Tutorial

1.in Label
The in tag of the thinkphp is used for a template variable within a range, using the following format:

 
  
   
  The content to output
 
  

When used, set variables and assign values to the template in a module operation (such as Index/display):

$groupId = 1; $this->assign ("GroupId", $groupId);

Template/tpl/default/index/display.html, use the in tag usage as follows:

 
  
   
  Manage groups
 
  

To run the example, you can output:

Manage groups

The PHP code for this example is equivalent to:

<?phpif (($groupId), explode (', ', ' In_array ')) {  echo ' management group ';}? >

Note: The value of a variable can also be a string or an array, and the value of the property can use a variable.

2.notin Label

There is also a notin tag corresponding to the in tag, that is, the judgment is not within a certain range:
Usage such as:

 
  
   
  Non-Administrative Groups
 
  

The combination of the two tag examples above is equivalent to:

 
  
   
  Manage group
  
    non-admin groups
 
  

3.range Label

thinkphp in and Notin tags can also be replaced with a range tag, such as:

 
  
   
  Manage groups
 
  

The above example is equivalent to the in tag, which is equivalent to the Notin label when the value of the Type property is Notin.
