Remove white space and parenthsis from global from entry variable

Question

I am using a phone number in a global variable called {{ global.phone }} with the format "(555) 555-5555". I'd like to use that same variable/string and remove spaces, dash, and parenthesis to use for the href tel link. I've tried a few different things from Twig and Craft documentation, but nothing is working. Here's what I have right now.

<p>Ph: <a href="tel:{{ global.phone|trim(' ') }}">{{ global.phone }}</a><br/>

Is this possible to do? If so any advise how to accomplish this?

Answer 1

I haven't tried this but I think that you can use the twig replace function. Something like:

{{ global.phone|replace({"(":"", ")":"", "-":"", " ":""}) }}

Update In your case, since the prefix (1-) is required, and "-" are allowable, the replace string for "(555) 555-5555" would be:

{{ global.phone|replace({"(" : "1-", ") " : "-"}) }}

Answer 2

For what it's worth, you can strip out all non-numerics with this something like this:

{{ globalPhoneNumber.phoneNumber|replace('/[^0-9]/', '') }}

Or, as part of a tel: anchor:

<a href="tel:{{ globalPhoneNumber.phoneNumber|replace('/[^0-9]/', '') }}">{{ globalPhoneNumber.phoneNumber }}</a>
