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

{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>
