Trying to come up with something for the xoopscode emails which comes up a little later in module.textsanitizer.php

$replacements[] = '<a href="mailto:\1">\1</a>';


replace with:

$replacements[] = "<script type="text/javascript">var em='\1';document.write('<a href="mailto:'+em+'">'+em+'</a>');</script>";



Look good?

I know this solution isn't ideal, but something is better than nothing. The '@', the '.' and the 'mailto:' get encoded. It should apply to all modules as well.

I'd appreciate comments on this - just learning PHP as I go. Ideally I'll only execute this if it's a mailto: link.

Edit the end of the &xoopsCodeDecode function in class/module.textsanitizer.php

$output = preg_replace($patterns, $replacements, $text);
        $output = str_replace('@', '&X64;', $output);
        $output = str_replace('.', '&X46;', $output);
        $output = str_replace('mailto:', '&X109;&X97;&X105;&X108;&X116;&X111;&X58;', $output);
        return $output;

        //return preg_replace($patterns, $replacements, $text);


In this example, you get the following for user@host.com:

<a href="&X109;&X97;&X105;&X108;&X116;&X111;&X58;user&X64;host&X46;com">user&X64 ;host&X46 ;com</a>


Replace &X with &# to get the right results.
