escape

escape is used to encode or escape a variable to for example html, url, single quotes, hex, hexentity, javascript and mail. By default its html.

Parameter Position	Type	Required	Possible Values	Default	Description
1	string	No	`html`, `htmlall`, `url`, `urlpathinfo`, `quotes`, `hex`, `hexentity`, `javascript`, `mail`	`html`	This is the escape format to use.
2	string	No	`ISO-8859-1`, `UTF-8`, and any character set supported by `htmlentities()`	`ISO-8859-1`	The character set encoding passed to htmlentities() et. al.

Example 5.10. escape


<?php

$smarty->assign('articleTitle',
                "'Stiff Opposition Expected to Casketless Funeral Plan'"
                );
$smarty->assign('EmailAddress','smarty@example.com');

?>

These are example escape template lines followed by the output


{$articleTitle}
'Stiff Opposition Expected to Casketless Funeral Plan'

{$articleTitle|escape}
&#039;Stiff Opposition Expected to Casketless Funeral Plan&#039;

{$articleTitle|escape:'html'}    {* escapes  & " ' < > *}
&#039;Stiff Opposition Expected to Casketless Funeral Plan&#039;

{$articleTitle|escape:'htmlall'} {* escapes ALL html entities *}
&#039;Stiff Opposition Expected to Casketless Funeral Plan&#039;

<a href="?title={$articleTitle|escape:'url'}">click here</a>
<a
href="?title=%27Stiff%20Opposition%20Expected%20to%20Casketless%20Funeral%20Plan%27">click here</a>

{$articleTitle|escape:'quotes'}
\'Stiff Opposition Expected to Casketless Funeral Plan\'

<a href="mailto:{$EmailAddress|escape:"hex"}">{$EmailAddress|escape:"hexentity"}</a>
{$EmailAddress|escape:'mail'}    {* this converts to email to text *}
<a href="mailto:%62%6f%..snip..%65%74">&#x62;&#x6f;&#x62..snip..&#x65;&#x74;</a>

{'mail@example.com'|escape:'mail'}
smarty [AT] example [DOT] com

Example 5.11. Other examples

PHP functions can be used as modifiers, $security permitting.


{* the "rewind" paramater registers the current location *}
<a href="{$SCRIPT_NAME}?page=foo&rewind={$smarty.server.REQUEST_URI|urlencode}">click here</a>

This snippet is useful for emails, but see also {mailto}


{* email address mangled *}
<a href="mailto:{$EmailAddress|escape:'hex'}">{$EmailAddress|escape:'mail'}</a>

See also escaping smarty parsing, {mailto} and the obfuscating email addresses page.
