Loop Output
Volist also has an alias iterate

Template Assignment:
$User = D (' User ')
$list = $User->findall ()
$this->assign (' list ', $list)

Template Definition:
<iterate name= "list" id= "vo" >
{$vo. name}
</iterate>

Note the meaning of the name and ID representation
//output List 5th to 15th record
<iterate name= "list" id= "vo" offset= "5" length= ' >
{$vo. name}
</iterate>

//output even record
<iterate name= "list" id= "vo" mod= "2" >
<eq name= "mod" value= "1" >
{$vo. name}
</eq>
</iterate>

//output Key
<iterate name= "list" id= "vo" key= "k" >
{$k}. {$vo. name}
</iterate>

//sub-loop Output
<volist name= "list" id= "vo" >
<iterate name= "vo[' sub ']" id= "sub" >
{$sub. name}
</iterate>
</volist>

Switch Label
<switch name= "name" >
<case value= "1" >value1</case>
<case value= "2" >value2</case>
<default/>default
</switch>
where the Name property can use functions and system variables , for example:
<switch name= "think.get.userid|abs" >
<case value= "1" >admin</case>
<default/>default
</switch>
You can also use variables for the Value property of the case, for Example:
<switch name= "userId" >
<case value= "$adminId" >admin</case>
<case value= "$memberId" >member</case>
<default/>default
</switch>

Compare Labels
<eq name= "name" value= "value" >value</eq>//name variable values equal to the output
<neq name= "name" value= "value" >value</neq>//name variable values are not equal to value output
<gt name= "name" value= "5" >value</gt>//the value of the name variable is greater than 5 for output
<egt name= "name" value= "5" >value</egt>//the value of the name variable is greater than or equal to 5 for output
<lt name= "name" value= "5" >value</lt>//the value of the name variable is less than 5 for output
<elt name= "name" value= "5" >value</elt>//the value of the name variable is less than or equal to 5 for output


//actually All of the above tags are aliases of compare tags
//where The value of the type attribute is the name of the judging tag listed above
<compare name= "name" value= "5" type= "eq" >value</compare>//the value of the name variable equals 5 on output

if label
<if condition= "$name eq 1" > value1
<elseif condition= "$name eq 2"/>value2
<else/> value3
</if>

C Operation
operation (dynamic) Configuration: mainly used in the action method
get:
C (' configuration Parameters ')
settings:
C (' config parameter ', new Value)

a Operation
to quickly create an action object:
$action = A (' User ');
is equivalent to
$action = new Useraction ();

D Operation
to quickly create a model data object:
$model = D (' User ');
is equivalent to
$model = new Usermodel ();

s Operation
Quick-action Caching Method
get:
S (' name ')
settings:
S (' name ', ' Value ');
delete:
S (' name ', NULL);

F Operation
How to save fast file data
use the same method as the S operation


L Operation
quickly manipulate language variables
get:
L (' language variable ');
settings:
L (' language variable ', ' value ');
such as: L (' user_info ', ' user information ');//set language variable with name User_info
Batch Assignment:
$arr [' language variable 1 '] = ' value 1 ';
$arr [' language variable 2 '] = ' Value 2 ';
L ($arr);
