XF 2.2 Use preg_replace on variable in template

[Arno Nühm]

I would like to strip all special characters from $__globals.thread.title variable.

$__globals.thread.title|replace("/[^0-9a-zA-Z \-\_]/", "")
doesn't work.

How can I do this?

I don't think regex is supported in the template filter function.

It likely needs to be a literal string, or an array.

This is a bit meh but it works.

<xf:set var="$specialChars" value="{{ ['ç', 'ş', 'ö'] }}" />

<xf:foreach loop="$specialChars" value="$char">
    <xf:set var="$thread.title" value="{{ $thread.title|replace($char, '') }}" />
</xf:foreach>

Obviously you need to define the array of special chars so it's not ideal.
