Regular Expression in Formatter

[bpj]

There's instructions for PHP formatters here:

Creating Custom Formatters (PHP and client-side)

I have been trying to supplement the native formatters in Wappler and found that most things can be added by using custom formatters. What I found, though was the technique for this was hidden in answers to specific questions so thought a short tutorial may help some: Server-side (php) In dmxConnectLib/lib/formatters create a file, call it something like customformatters.php (do not alter the native files as it could be overwritten with updates) Add the relevant code: the function name shoul…

Probably something like this:

<?php namespace lib\core; 
function formatter_regexreplace($str, $pattern){ 
$retval = preg_replace($pattern, '', $str);
return $retval; 
} ?>

You would then use it in a data binding code view as:

somevalue.regexreplace('thepattern')

e.g.
somevalue.regexreplace('([0-9])')

to remove digits
