assign() an array to Smarty

<?php
$data = array(1000,1001,1002);
$smarty->assign('custid',$data);
?>

The template that outputs the array

{* this example will print out all the values of the $custid array *}
{section name=customer loop=$custid}
{section customer $custid} {* short-hand *}
  id: {$custid[customer]}<br />
{/section}
<hr />
{*  print out all the values of the $custid array reversed *}
{section name=foo loop=$custid step=-1}
{section foo $custid step=-1} {* short-hand *}
  {$custid[foo]}<br />
{/section}

  

The above example will output:

id: 1000<br />
id: 1001<br />
id: 1002<br />
<hr />
id: 1002<br />
id: 1001<br />
id: 1000<br />

  

{section name=foo start=10 loop=20 step=2}
  {$smarty.section.foo.index}
{/section}
<hr />
{section name=bar loop=21 max=6 step=-2}
  {$smarty.section.bar.index}
{/section}

The above example will output:

  
10 12 14 16 18
<hr />
20 18 16 14 12 10

  

The name of the {section} can be anything you like, see PHP variables. It is used to reference the data within the {section}.

{section name=anything loop=$myArray}
  {$myArray[anything].foo}
  {$name[anything]}
  {$address[anything].bar}
{/section}

  

This is an example of printing an associative array of data with a {section}. Following is the php script to assign the $contacts array to Smarty.

  
<?php
$data = array(
          array('name' => 'John Smith', 'home' => '555-555-5555',
                'cell' => '666-555-5555', 'email' => 'john@myexample.com'),
          array('name' => 'Jack Jones', 'home' => '777-555-5555',
                'cell' => '888-555-5555', 'email' => 'jack@myexample.com'),
          array('name' => 'Jane Munson', 'home' => '000-555-5555',
                'cell' => '123456', 'email' => 'jane@myexample.com')
        );
$smarty->assign('contacts',$data);
?>

  

The template to output $contacts

{section name=customer loop=$contacts}
<p>
  name: {$contacts[customer].name}<br />
  home: {$contacts[customer].home}<br />
  cell: {$contacts[customer].cell}<br />
  e-mail: {$contacts[customer].email}
</p>
{/section}

  

The above example will output:

<p>
  name: John Smith<br />
  home: 555-555-5555<br />
  cell: 666-555-5555<br />
  e-mail: john@myexample.com
</p>
<p>
  name: Jack Jones<br />
  home phone: 777-555-5555<br />
  cell phone: 888-555-5555<br />
  e-mail: jack@myexample.com
</p>
<p>
  name: Jane Munson<br />
  home phone: 000-555-5555<br />
  cell phone: 123456<br />
  e-mail: jane@myexample.com
</p>

  

This example assumes that $custid, $name and $address are all arrays containing the same number of values. First the php script that assign's the arrays to Smarty.

<?php

$id = array(1001,1002,1003);
$smarty->assign('custid',$id);

$fullnames = array('John Smith','Jack Jones','Jane Munson');
$smarty->assign('name',$fullnames);

$addr = array('253 Abbey road', '417 Mulberry ln', '5605 apple st');
$smarty->assign('address',$addr);

?>

The loop variable only determines the number of times to loop. You can access ANY variable from the template within the {section}. This is useful for looping multiple arrays. You can pass an array which will determine the loop count by the array size, or you can pass an integer to specify the number of loops.

{section name=customer loop=$custid}
<p>
  id: {$custid[customer]}<br />
  name: {$name[customer]}<br />
  address: {$address[customer]}
</p>
{/section}

  

The above example will output:

<p>
  id: 1000<br />
  name: John Smith<br />
  address: 253 Abbey road
</p>
<p>
  id: 1001<br />
  name: Jack Jones<br />
  address: 417 Mulberry ln
</p>
<p>
  id: 1002<br />
  name: Jane Munson<br />
  address: 5605 apple st
</p>

  

{section}'s can be nested as deep as you like. With nested {section}'s, you can access complex data structures, such as multi-dimensional arrays. This is an example .php script thats assign's the arrays.

<?php

$id = array(1001,1002,1003);
$smarty->assign('custid',$id);

$fullnames = array('John Smith','Jack Jones','Jane Munson');
$smarty->assign('name',$fullnames);

$addr = array('253 N 45th', '417 Mulberry ln', '5605 apple st');
$smarty->assign('address',$addr);

$types = array(
           array( 'home phone', 'cell phone', 'e-mail'),
           array( 'home phone', 'web'),
           array( 'cell phone')
         );
$smarty->assign('contact_type', $types);

$info = array(
           array('555-555-5555', '666-555-5555', 'john@myexample.com'),
           array( '123-456-4', 'www.example.com'),
           array( '0457878')
        );
$smarty->assign('contact_info', $info);

?>
  

In this template, $contact_type[customer] is an array of contact types for the current customer.

{section name=customer loop=$custid}
<hr>
  id: {$custid[customer]}<br />
  name: {$name[customer]}<br />
  address: {$address[customer]}<br />
  {section name=contact loop=$contact_type[customer]}
    {$contact_type[customer][contact]}: {$contact_info[customer][contact]}<br />
  {/section}
{/section}

  

The above example will output:

<hr>
  id: 1000<br />
  name: John Smith<br />
  address: 253 N 45th<br />
    home phone: 555-555-5555<br />
    cell phone: 666-555-5555<br />
    e-mail: john@myexample.com<br />
<hr>
  id: 1001<br />
  name: Jack Jones<br />
  address: 417 Mulberry ln<br />
    home phone: 123-456-4<br />
    web: www.example.com<br />
<hr>
  id: 1002<br />
  name: Jane Munson<br />
  address: 5605 apple st<br />
    cell phone: 0457878<br />

  

Results of a database search (eg ADODB or PEAR) are assigned to Smarty

  
<?php
$sql = 'select id, name, home, cell, email from contacts '
      ."where name like '$foo%' ";
$smarty->assign('contacts', $db->getAll($sql));
?>

The template to output the database result in a HTML table

<table>
<tr><th>&nbsp;</th><th>Name></th><th>Home</th><th>Cell</th><th>Email</th></tr>
{section name=co loop=$contacts}
  <tr>
    <td><a href="view.php?id={$contacts[co].id}">view<a></td>
    <td>{$contacts[co].name}</td>
    <td>{$contacts[co].home}</td>
    <td>{$contacts[co].cell}</td>
    <td>{$contacts[co].email}</td>
  <tr>
{sectionelse}
  <tr><td colspan="5">No items found</td></tr>
{/section}
</table>
