Math can be applied directly to variable values.

Example 3-7. math examples

{$foo+1}

{$foo*$bar}

{* some more complicated examples *}

{$foo->bar-$bar[1]*$baz->foo->bar()-3*7}

{if ($foo+$bar.test%$baz*134232+10+$b+10)}

{$foo|truncate:”`$fooTruncCount/$barTruncFactor-1`”}

{assign var=”foo” value=”`$foo+$bar`”}

See also the {math} function for complex equations and {eval}.

Smarty will recognize assigned variables embedded in “double quotes” so long as the variable name contains only numbers, letters, under_scores and brackets[]. See naming for more detail.

With any other characters, for example a .period or $object>reference, then the variable must be surrounded by `backticks`.

You cannot embed modifiers, they must always be [...] No related posts.

Most of the functions take attributes that specify or modify their behavior. Attributes to Smarty functions are much like HTML attributes. Static values don’t have to be enclosed in quotes, but it is recommended for literal strings. Variables may also be used, and should not be in quotes.

Some attributes require boolean values (TRUE or FALSE). [...] No related posts.

Every Smarty tag either prints a variable or invokes some sort of function. These are processed and displayed by enclosing the function and its attributes within delimiters like so: {funcname attr1=’val1′ attr2=’val2′}.

Example 3-3. function syntax

{config_load file=’colors.conf’}

{include file=’header.tpl’} {insert file=’banner_ads.tpl’ title=’Smarty is cool’}

{if $logged_in} Welcome, {$name}! {else} hi, {$name} {/if}

Template variables start with the $dollar sign. They can contain numbers, letters and underscores, much like a PHP variable. You can reference arrays by index numerically or non-numerically. Also reference object properties and methods.

Config file variables are an exception to the $dollar syntax and are instead referenced with surrounding #hashmarks#, or via the $smarty.config variable.

This is the full system path to the location of the Smarty core files. If not defined, Smarty will default this constant to the internals/ sub-directory below SMARTY_DIR. If defined, the path must end with a slash/. Use this constant when manually including any of the core.* files.

Template comments are surrounded by asterisks, and that is surrounded by the delimiter tags like so:

Smarty comments are NOT displayed in the final output of the template, unlike <!-- HTML comments -->. These are useful for making internal notes in the templates which no one will see

This is the simplest type. A boolean expresses a truth value. It can be either TRUE or FALSE.

Note: The boolean type was introduced in PHP 4.

Syntax

To specify a boolean literal, use the keywords TRUE or FALSE. Both are case-insensitive.

PHP supports the concept of variable functions. This means that if a variable name has parentheses appended to it, PHP will look for a function with the same name as whatever the variable evaluates to, and will attempt to execute it. Among other things, this can be used to implement callbacks, function tables, and [...] No related posts.

Values are returned by using the optional return statement. Any type may be returned, including arrays and objects. This causes the function to end its execution immediately and pass control back to the line from which it was called. See return() for more information.

Example #1 Use of return()

Information may be passed to functions via the argument list, which is a comma-delimited list of expressions.

PHP supports passing arguments by value (the default), passing by reference, and default argument values. Variable-length argument lists are also supported, see also the function references for func_num_args(), func_get_arg(), and func_get_args() for more information.

In many occasions, you may want to compare the same variable (or expression) with many different values, and execute a different piece of code depending on which value it equals to. This is exactly what the switch statement is for.
