Much of the Smarty 2 syntax is supported -by a wrapper but deprecated. See the README that comes with Smarty 3 for more -information. - -The {$array|@mod} syntax has always been a bit confusing, where an "@" is required -to apply a modifier to an array instead of the individual elements. Normally you -always want the modifier to apply to the variable regardless of its type. In Smarty 3, -{$array|mod} and {$array|@mod} behave identical. It is safe to drop the "@" and the -modifier will still apply to the array. If you really want the modifier to apply to -each array element, you must loop the array in-template, or use a custom modifier that -supports array iteration. Most smarty functions already escape values where necessary -such as {html_options} - -== PHP Version == -Smarty 3 is PHP 5 only. It will not work with PHP 4. - -== {php} Tag == -The {php} tag is disabled by default. The use of {php} tags is -deprecated. It can be enabled with $smarty->allow_php_tag=true. - -But if you scatter PHP code which belongs together into several -{php} tags it may not work any longer. - -== Delimiters and whitespace == -Delimiters surrounded by whitespace are no longer treated as Smarty tags. -Therefore, { foo } will not compile as a tag, you must use {foo}. This change -Makes Javascript/CSS easier to work with, eliminating the need for {literal}. -This can be disabled by setting $smarty->auto_literal = false; - -== Unquoted Strings == -Smarty 2 was a bit more forgiving (and ambiguous) when it comes to unquoted strings -in parameters. Smarty3 is more restrictive. You can still pass strings without quotes -so long as they contain no special characters. (anything outside of A-Za-z0-9_) - -For example filename strings must be quoted -<source lang="smarty"> -{include file='path/foo.tpl'} -</source> - -== Extending the Smarty class == -Smarty 3 makes use of the __construct method for initialization. If you are extending -the Smarty class, its constructor is not called implicitly if the your child class defines -its own constructor. In order to run Smarty's constructor, a call to parent::__construct() -within your child constructor is required. - -<source lang="php"> -class MySmarty extends Smarty { - function __construct() { - parent::__construct(); - - // your initialization code goes here - - } -} -</source> - -== Autoloader == -Smarty 3 does register its own autoloader with spl_autoload_register. If your code has -an existing __autoload function then this function must be explicitly registered on -the __autoload stack. See http://us3.php.net/manual/en/function.spl-autoload-register.php -for further details. - -== Plugin Filenames == -Smarty 3 optionally supports the PHP spl_autoloader. The autoloader requires filenames -to be lower case. Because of this, Smarty plugin file names must also be lowercase. -In Smarty 2, mixed case file names did work. - -== Scope of Special Smarty Variables == -In Smarty 2 the special Smarty variables $smarty.section... and $smarty.foreach... -had global scope. If you had loops with the same name in subtemplates you could accidentally -overwrite values of parent template. - -In Smarty 3 these special Smarty variable have only local scope in the template which -is defining the loop. If you need their value in a subtemplate you have to pass them -as parameter. -<source lang="smarty"> -{include file='path/foo.tpl' index=$smarty.section.foo.index} -</source> - -== SMARTY_RESOURCE_CHAR_SET == -Smarty 3 sets the constant SMARTY_RESOURCE_CHAR_SET to utf-8 as default template charset. -This is now used also on modifiers like escape as default charset. If your templates use -other charsets make sure that you define the constant accordingly. Otherwise you may not -get any output. - -== newline at {if} tags == -A \n was added to the compiled code of the {if},{else},{elseif},{/if} tags to get output of newlines as expected by the template source. -If one of the {if} tags is at the line end you will now get a newline in the HTML output. - -== trigger_error() == -The API function trigger_error() has been removed because it did just map to PHP trigger_error. -However it's still included in the Smarty2 API wrapper. - -== Smarty constants == -The constants -SMARTY_PHP_PASSTHRU -SMARTY_PHP_QUOTE -SMARTY_PHP_REMOVE -SMARTY_PHP_ALLOW -have been replaced with class constants -Smarty::PHP_PASSTHRU -Smarty::PHP_QUOTE -Smarty::PHP_REMOVE -Smarty::PHP_ALLOW - |
