This is a complete list of all the functions you can use in Exponential templates. Some functions are native to the eZ template library (and can be used in other applications), while others are specific for eZ publish.

Exponential template library functions

section (delimiter, section-exclude, section-include, section-else)

Used for looping over arrays and numeric ranges, and conditional control of block and sequences.
Several input parameters and sub functions are available. Requires an end tag. More...

ldelim

Outputs the { sign (left curly bracket). Requires no end tag. More...

rdelim

Outputs the } sign (right curly bracket). Requires no end tag. More...

include

Includes another template file. Requires no end tag. More...

switch (case)

Allows conditional control of output. Requires an end tag. More...

sequence

Creates a sequence that can be iterated over, wrapping around to the beginning when the end is
reached. Requires no end tag. More...

let, default

Assigns one or more variables within its tags. Requires an end tag. "default" assigns the variables
unless they are already assigned, while "let" always assigns them. The assigned variables are freed
(released) at the end tag.
E.g.

{let var1=42 var2='forty-two'}

Variables: {$var1} ({$var2})

{/let}

This will output "Variables: 42 (forty-two)".

{let var1=42 var2='forty-two'}

{default var1=53}

Variables: {$var1} ({$var2})

{/default}

{/let}

This will output "Variables: 42 (forty-two)", because the first variable was set before the
default statement.

By passing name as a parameter all variables will be created in the new namespace:

{let name=NewNameSpace ...}

You can even use let to change the namespace by passing no assignments:

{let name=First}

 {let name=Second}

 {/let}

{/let}

set

Assigns a value to one or more variables. The value must have been created earlier using let
or default. Requires no end tag.
E.g.

{let var=4}

Before: {$var}

{set var=42}

After: {$var}

{/let}

This will output "Before: 4 After: 42".

set-block

Renders all it's children as text and sets it as a template variable. This is useful for allowing
one template to return multiple text portions, for instance an email template could set subject as a
block and return the rest as body. Requires an end tag.
The scope parameter can be global, root or relative:
global - Sets the variable in the defined subspace (if any) in the global namespace
root - Sets the variable in the defined subspace in the root namespace of the current file
(may be the same as global namespace in some cases)
relative - Sets the variable in the defined subspace from the current namespace.
E.g.

{set-block name=MyNameSpace scope=global variable=text}

{$item} - {$item2}

{/set-block}

This will render the output into the variable "text".

append-block

Similar to set-block but will create an array out of all appends instead. Requires an end tag.
E.g.

{append-block scope=global variable=extra_header_data}

 {* Add some code, for instance a java script *}

{/append-block}

Then, in a template, you could to this:

{section loop=$#extra_header_data show=is_set($#extra_header_data)}

{$:item}

{/section}

run-once

Assures that the content of the block is run only once in a page view, it uses the current filename
and placement to figure this out. This can be useful if you want a text to appear once or a calculation
to be run once for included templates or loops. Requires an end tag.

cache-block

Caches the content of the block. It takes one or both of these two input parameters:

• keys, which determines the cache key, and
• expiry, which sets the expiry time in seconds.

The cache key can be a simple value like a string or an integer, or an array of simple values. Requires an end tag.

E.g.

{cache-block keys=$node_id expiry=60}

{* Do something that needs caching *}

{/cache-block}

Exponential kernel functions

on as template variables.
E.g.

{attribute_view_gui attribute=$myAttribute}

parameter. Any other parameters are passed on as template variables.

content_view_gui

Show a content object. You must supply the content_object parameter. The view parameter, specifying
which view mode to use, is optional. Any other parameters are passed on as template variables.

content_version_view_gui

Show a content object version. You must supply the content_version parameter. The view parameter,
