Vii. Integration Smarty to the MVC one , built-in functions 1,if...elseif...else...if

Basic syntax

{if}

{ElseIf}

{Else}

{/if}

Function: Implement if selection structure

Example code:

Run Result: Write code 2, Ldelim, Rdelim

{Ldelim}

{Rdelim}

Function: Output Smarty label left and right delimiter

Example code:

Operating effect:

3, literal

Basic syntax:

{literal}

Content (CSS code or JS code)

{/literal}

Function: The data in the literal label area will be treated as text, at which point the template ignores all character information inside it. This feature is used to display CSS or JavaScript scripts that may contain character information, such as curly braces. When this information is in the {literal}{/literal} tab, the template engine will not parse them and display them directly.

Example code:

The effect is as follows:

4. PHP

Basic syntax

{PHP}

PHP code

{/php}

Features: allows us to use PHP code in the Smarty template engine (but not recommended)

In Smarty3.0 the syntax has been abolished, if you want to use it, please use the SMARTYBC portal

Example:

Effect: 2015-02-11 00:00:00 5, section

Basic syntax:

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

{/section}

Function: Implement an array (index starting at 0 and continuous) traversal

Parameter description:

Loop: the array to traverse

Name: The traversal index is placed in name each time it is traversed

Start: Index to start by default

Step: Steps or Pace, default is 1

Max: Maximum number of cycles

Example code:

Example 1: Traversing a one-dimensional array

Operation Result:

Section vs. foreach:

foreach can traverse an array, and after each traversal, the traversed content is saved in the item option, which is a true traversal of the arrays. Similar to the Foreach Loop in PHP

The section can also implement an array traversal, but each time the loop is used, the system simply determines the number of elements in the array and determines the number of loops, and puts the circular index into the name option, which is not a true traversal of the array, but is similar to a for loop in PHP code.

Example 2:section parameter use

The effect is as follows:

Example 3:section traversing a two-dimensional array

Operation Result:

Section attached properties

{$smarty. Section.name.index}: Circular index, default starting from 0

{$smarty. Section.name.index_prev}: Last index of the current index

{$smarty. Section.name.index_next}: Next index for the current index

{$smarty. section.name.iteration}: First loop (iteration)

{$smarty. Section.name.first}: The condition is true when the first loop

{$smarty. Section.name.last}: The condition is true when the last loop

{$smarty. section.name.total}: Total number of loops

Example code:

Operating effect:

6, Strip

{Strip}

Formatting code

{/strip}

Function: Remove the leading and trailing spaces and line breaks of elements

Example code:

Operating effect:

right mouse button to view source code:

Basic syntax

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

Function: Counter

Parameter description:

Start: Default start number, default is 1

Skip: Step or pace

Print: Whether the output is currently

Sample code

Operating effect:

2. Cycle

Function: Realize wheel display operation

Basic syntax:

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

Example code:

Operating effect:

3. Debug

Example code:

Operating effect:

5, Html_image

Basic syntax

{html_image file= "pumpkin.jpg"}

Example code:

6 , Html_table

Basic syntax:

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

Function: Convert the array (simple) into a table

Parameter description:

Loop: the array to traverse

COLS: How many columns are displayed

Table_attr: Table Properties, multiple properties are separated by spaces, or you can use style

Example code:

Operating effect:

7 , html_checkboxes check box

Basic syntax:

{html_checkboxes name= ' cust ' values= $cust _ids checked= $customer _id output= $cust _names separator= "<br/>"}
