I am writing a snippet for cleansing slugs from user input:

<?php
/**
*
* usage : [[createSlug? &string=`s/o/m/e/-/s/l/a/s/h/e/s`]]
*
*/
$res = $modx->newObject('modResource');
$res->set('alias', $res->cleanAlias($string));
$alias = $res->get('alias');
unset($res);
return $alias;

cleanAlias() doesn't strip the forward slashes.
I could use str_replace() but it would be cleaner to use the $options array.

However the following code

$string='s/o/m/e/-/s/l/a/s/h/e/s';
$options = array('/');
$res->cleanAlias($string, $options)

doesn't work for me.

Hi,

I think your options are a bit off

It should be an array like with system setting values

$option = array('friendly_alias_restrict_chars_pattern'=>'/[\/\0\x0B\t\n\r\f\a&=+%#<>"~`@\?\[\]\{\}\|\^\'\\\\]/'');

(i changed the pattern but don't know if it will work tongue

yes that works, thanks a lot!
(one too many apostrophes at the end though: removed below)

<?php
/**
*
* usage : [[createSlug? &string=`s/o/m/e/-/s/l/a/s/h/e/s`]]
*
*/
$options = array('friendly_alias_restrict_chars_pattern'=>'/[\/\0\x0B\t\n\r\f\a&=+%#<>"~`@\?\[\]\{\}\|\^\'\\\\]/');

$res = $modx->newObject('modResource');
$res->set('alias', $res->cleanAlias($string, $options));
$alias = $res->get('alias');
return $alias;
