Example Analysis _php instance of Smarty Cyclic embedding method

The example in this article describes the Smarty cyclic nesting method. Share to everyone for your reference, specific as follows:

test3.php:

<?php
require "main.php";
$forum = Array (
    array ("category_id" => 1, "Category_name" => "Bulletin Area",
      "topic" => Array (
        array ("topic _id "=> 1, topic_name" => "Station Bulletin"))
    ,
    Array ("category_id" => 2, "Category_name" => "literary Zone",
      "topic" => Array (
        "topic_id" => 2, "topic_name" => "Good Book Introduction"),
        Array ("TOPIC_ID" => 3, " topic_name "=>" Chiven))
    ,
    Array ("category_id" => 3, "Category_name" => "Computer Zone",
      "topic" => Array (
        array ("TOPIC_ID" => 4, "topic_name" => "Hardware Perimeter"),
        Array ("TOPIC_ID" => 5, "topic_name" = > "Software discussion")
      )
;
$TPL->assign ("forum", $forum);
$tpl->display ("test3.htm");
? >

The sample version is as follows:

Templates/test3.htm:

test2.php:

<?php require_once ('./include/db_fns.php '); Include_once ("./smarty/libs/smarty.class.php"); Contains the Smarty class file $smarty = new Smarty (); Establish Smarty instance Object $smarty $smarty->template_dir = "./templates/dedecms";//Set template directory $smarty->compile_dir = "templates /templates_c ";
Sets the compilation directory $smarty->assign ("Template_url", "./");
$smarty->assign ("$site _url", "http://www.jb51.net/");
$smarty->assign ("$site _name", "Article Management System"); $smarty->left_delimiter = "<{"; Set the left border character $smarty->right_delimiter = "}>";
Set the right border character $db _conn = Db_connect ();
$query = "Select Cat_id,cat_name from Categories order by cat_id DESC";
$result = mysql_query ($query);
$i = 5;
                while ($row = Mysql_fetch_array ($result)) && $i > 0) {$query 2= "select ID, Post_title, post_date From post WHERE post.post_category = $row [cat_id] and post_status <> ' Unpbu
        Lish ' ORDER by post_date DESC ';
        $result 2=mysql_query ($query 2); 
    $i = 5;    while ($row 2 = mysql_fetch_array ($result 2)) && $i > 0) {$row 2[post_date]=date (' m-d ', St
            Rtotime ($row 2[post_date])); $category = Array ("cat_id" => "$row [cat_id]", "Cat_name" => "$row [Cat_name]", "POST" =>array ("ID" => "$row
            2[id] "," Post_title "=>" $row 2[post_title] "," Post_category "=>" $row 2[post_category] ",
            "Post_date" => "$row 2[post_date]");
        $i--;
}} $smarty->assign ("forum", $category);

 $smarty->display ("test2.htm");?>

Test2.htm:

test4.php:

<?php
require "main.php";
$my _array = Array (
array ("value" => "0"), array
("value" => "1"), array
("Value" => "2"),
array ("Value" => "3"), Array ("value"
=> "4"),
Array ("Value" => "5"),
Array ("Value" => "6")
, Array ("Value" => "7"),
Array ("Value" => "8"),
Array ("Value" => "9"));
$tpl->assign ("My_array", $my _array);
$tpl->display (' test4.htm ');
? >

The template is written as follows:

Templates/test4.htm:

The point is $smarty. section.sec1.rownum this smarty variable, which gets the index value starting at 1 in the section loop, so when rownum can be removed by 2, it outputs </tr><tr> Make a Table change column (note!) Is </tr> in front <tr> in the back). So the number 2 is the number of pens we want to render in a column. You can change different ways of presenting.

operators have the following :

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

Example:

<!--{if $bigsize ge ' 650 '}-->
    "border=" 0 "width=" 650 "class=" Product_photo "/>
<!--{else}-->
     "border=" 0 "class=" Product_photo "/>
<!--{/if}-->

Formerly not commonly used smarty, these two days have a friend's website to change, conveniently use a bit, still quite interesting.

Notes on Capture:

The role of the capture function is to collect data from the template output into a variable, rather than outputting them to the page.

Any data between {capture Name= "foo"} and {/capture} is received in the variable specified by the function's Name property ($foo).

The information collected can be used in special variable $smarty.

For example, Capture.foo collects the above data. If the function does not have a name attribute, it will use "default".

Each {capture} must correspond to {/capture} and cannot be nested using the capture function.
