Php-Smarty-5 (22), phpsmarty-522. Php-Smarty-5 (22), phpsmarty-522 connected to the previous 11, section, sectionelsesection is a loop structure statement, mainly used to traverse the array syntax: {sectionname name loop php-Smarty-5 (22), phpsmarty-522

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

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 ="
"}

Values: array of Values

Checked: array of the values of the selected items

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.
