11. section and sectionelse section are loop structure statements used to traverse arrays.

Syntax:

{Section name = name loop = loop array (times) start = start (0) step = step (1) max = maximum number of cycles}
{Sectionelse}

{/Section}

Name: Required for section statement naming

Loop: required for Loop Array

Start: Start index default value: 0

Step: Step Size default value: 1

Max: Maximum number of cycles default value: total length

Differences between Foreach and section:

Foreach refers to directly traversing an array.

Section is a loop statement. Its number of loops is determined by the number of arrays.

Section is more selective in traversing arrays.

 

L section built-in Variables

 

{$ Smarty. section. name. index} cyclic index

{$ Smarty. section. name. index_prev} previous cyclic Index

{$ Smarty. section. name. index_next} next cycle index

{$ Smarty. section. name. iteration} the cyclic index starts from 1.

The values {$ smarty. section. name. first | last} are true for 1st and last execution.

Total number of {$ smarty. section. name. total} cycles

12. strip remove consecutive Spaces

Syntax:

{Strip}

......

{/Strip}

 

Ii. User-Defined Functions

1. Create template variables for assign

{Assign var = "var" value = "value "}

Var: Specifies the variable name.

Value: Specifies the variable Value.

2. counter counters

Syntax:

{Counter start = 0 skip = 2 print = false}

Start: Start value

Skip: the default step size is 1.

Print: whether to output this time

 

3. cycle Rotation

<Tr bgcolor = "{cycle values =" # eeeeee, # d0d0d0 "}">

Values: list of Values to rotate

 

4. debug open debugging window

5. eval calculates the variable value.

Syntax:

{Eval var = # ErrorState # assign = "state_error "}

Var: name of the variable to be calculated

Assign: saves the result, but does not output this time.

 

6. fetch reads and outputs the File Content

 

{Fetch file = "file" assign = "var "}

File: File Name

Assign: Save the result and do not output it this time.

7. Print an image on the html_image page.

{Html_image file = "pumpkin.jpg "}

File: Image address

 

8. html_table displays the array elements in the table (only applicable to simple arrays)

 

{Html_table loop = $ data cols = 4 table_attr = 'border = "0 "'}

Loop: Required for the array to be traversed

Cols: the number of cells displayed in each row is three by default.

Table_asd: table attributes

9. Print a set of check boxes in html_checkboxes

 

{Html_checkboxes values = $ cust_ids checked = $ customer_id output = $ cust_names separator = "<br/> "}

 

Values: array of Values

Checked: array of the value of the selected item

Output: Text Array

Separator: Separator separated between multiple options

Name: Name this set of check boxes. Note: [] is automatically added to smarty, indicating that it is an array.
