Attribute Name	Type	Required	Default	Description
name	string	Yes	n/a	The name of the section
loop	[$variable_name]	Yes	n/a	The name of the variable to determine # of loop iterations
start	integer	No	0	The index position that the section will begin looping. If the value is negative, the start position is calculated from the end of the array. For example, if there are seven values in the loop array and start is -2, the start index is 5. Invalid values (values outside of the length of the loop array) are automatically truncated to the closest valid value.
step	integer	No	1	The step value that will be used to traverse the loop array. For example, step=2 will loop on index 0,2,4, etc. If step is negative, it will step through the array backwards.
max	integer	No	1	Sets the maximum number of times the section will loop.
show	boolean	No	true	determines whether or not to show this section

Template sections are used for looping over arrays of data. All section tags must be paired with /section tags. Required parameters are name and loop. The name of the section can be anything you like, made up of letters, numbers and underscores. Sections can be nested, and the nested section names must be unique from each other. The loop variable (usually an array of values) determines the number of times the section will loop. When printing a variable within a section, the section name must be given next to variable name within brackets []. sectionelse is executed when there are no values in the loop variable.

Example 7-15. section

{* this example will print out all the values of the $custid array *}
{section name=customer loop=$custid}
	id: {$custid[customer]}<br>
{/section}

OUTPUT:

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

Example 7-16. section loop variable

{* the loop variable only determines the number of times to loop.
   you can access any variable from the template within the section.
   This example assumes that $custid, $name and $address are all
   arrays containing the same number of values *}
{section name=customer loop=$custid}
	id: {$custid[customer]}<br>
	name: {$name[customer]}<br>
	address: {$address[customer]}<br>
	<p>
{/section}


OUTPUT:

id: 1000<br>
name: John Smith<br>
address: 253 N 45th<br>
<p>
id: 1001<br>
name: Jack Jones<br>
address: 417 Mulberry ln<br>
<p>
id: 1002<br>
name: Jane Munson<br>
address: 5605 apple st<br>
<p>

Example 7-17. section names

{* the name of the section can be anything you like,
   and it is used to reference the data within the section *}
{section name=mydata loop=$custid}
	id: {$custid[mydata]}<br>
	name: {$name[mydata]}<br>
	address: {$address[mydata]}<br>
	<p>
{/section}

Example 7-18. nested sections

{* sections can be nested as deep as you like. With nested sections,
   you can access complex data structures, such as multi-dimensional
   arrays. In this example, $contact_type[customer] is an array of
   contact types for the current customer. *}
{section name=customer loop=$custid}
	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}
	<p>
{/section}

Example 7-19. sections and associative arrays

{* This is an example of printing an associative array
   of data within a section *}
{section name=customer loop=$contacts}
	name: {$contacts[customer].name}<br>
	home: {$contacts[customer].home}<br>
	cell: {$contacts[customer].cell}<br>
	e-mail: {$contacts[customer].email}<p>
{/section}


OUTPUT:

name: John Smith<br>
home: 555-555-5555<br>
cell: 555-555-5555<br>
e-mail: john@mydomain.com<p>
name: Jack Jones<br>
home phone: 555-555-5555<br>

Example 7-20. sectionelse

{* sectionelse will execute if there are no $custid values *}
{section name=customer loop=$custid}
	id: {$custid[customer]}<br>
{sectionelse}
	there are no values in $custid.
{/section}

Sections also have their own variables that handle section properties. These are indicated like so: {$smarty.section.sectionname.varname}

NOTE: As of Smarty 1.5.0, the syntax for section property variables has been changed from {%sectionname.varname%} to {$smarty.section.sectionname.varname}. The old syntax is still supported, but you will only see reference to the new syntax in the manual examples.
