Smarty control statement

The following three methods are common: if-elseif-else, foreach, and section, which are used to control the content output structure. Therefore, in today's php Tutorial: this tutorial is partly from the Internet, partly from the manual and provides a smarty Chinese hand

1. conditional selection structure if-elseif-else

<{If expression}>... <{else}>... <{/if}>

Conditional modifier: eq, ne, neq, gt, lt, lte, le, gte, ge, is even, is odd, is not even, is not odd, not, mod, div by, even by, odd by, = ,! =,>, <, <=,> =.

 

Explanation:

Equal: equal, not equal: not equal to, greater than: greater than, less than: less than, less than or equal: less than or equal to, great than or equal: greater than or equal to, is even: is an even number, is odd: is an odd number, is not even: not an even number, is not odd: not an odd number, not: not, mod: Remainder, div by: is... Division

 

{if $name eq "admin"} ......{elseif $name eq "Wilma"}}......{else}......{/if} 

2. use foreach for loop traversal

<{Foreach expression}>... <{foreachelse}>... <{/foreach}>

Attribute Name	Type	Required	Default	Description
From	Array	Yes required	N/	Array of circular access
Item	String	Yes required	N/	Variable name of the current element
Key	String	No	N/	Variable name of the current key name
Name	String character	No	N/	Name of the foreach loop used to access the foreach attribute

$ Smarty-> assign ("contacts", array ("phone" => "1", "fax" => "2 ", "cell" => "3"), array ("phone" => "555-4444", "fax" => "555-3333 ", "php Tutorial" => "www.phpddt.com "))); *} {foreach name = outer item = contact from = $ contacts} {foreach key = key item = item from = $ contact} {$ key }:{$ item}
{/Foreach}

3. section for more complex loop traversal

<{Section loop = $ varName [, start = $ start, step = $ setp, max = $ max, $ show = true]}>

Name: section name. $ is not required;

$ Loop: the variable to be cyclic. To the extent, use assign to operate the variable.

$ Start: subscript of the start loop. The default value is 0;

$ Step: increment of the lower mark in each cycle;

$ Show: boolean type. Determines whether to display this block. The default value is true;

<{Section}> attributes;

Index: The subscript of the loop. The default value is 0;

Index_prev: the previous value of the current base object. the default value is-1;

Index_next: the next value of the current underlying object. the default value is 1;

First: whether it is the first next loop;

Last: whether it is the last loop;

Iteration: number of cycles;

Rownum: current row number, alias of iteration;

Loop: The Last loop number. Number of cycles of a Section;

Show: whether to display;

<{Section loop = $ News}>

News No.: <{$ News [loop]. newID}>

News content: <{$ News [loop]. newTitle}>

<{Sectionelse}>

I am sorry

<{/Section}>

For one-dimensional arrays:

{Section name = row loop = $ list}

{$ List. name}

{/Section}

For two-dimensional arrays:

{Section name = row loop = $ list}

{$ List [row]. name}

{/Section}

In addition, you can directly output a single output:

<{$ CommendList.0.infoType}>

<{$ CommendList.1.infoType}>

For 3D arrays:

<{Section name = cate loop = $ myarray}>

<{Section name = scate loop = $ myarray [cate]}>

Id ------> <{$ myarray [cate] [scate]. id}>

Title --------> <{$ myarray [cate] [scate]. title}>

Url ----------> <{$ myarray [cate] [scate]. url}>

<{/Section}>

<{/Section}>
