Embedding Anti-spam email link obfuscator

[Hans]

I really don't know if it helps, but it will prevent some spambots at least I hope.
I want to embed this code into a contact page. I pasted it in a wysiwyg page and it works fine, but when I go and edit the page again, the code disappears.
So I think it has to be placed in a code page, and of course I tried that by echo ' <code> ';
But that doesn't work.
I hope there is a solution for it.
Here's the code:

Code:

<script type="text/javascript" language="javascript">
<!--
{ coded = "5OSQjFZ95t@HuZ9M.Oh"
  key = "48TalNouG9wWzKbmRrxiksZh1QCfnUPvBeFXjI56M37y2DSOpJcVtALgEH0Ydq"
  shift=coded.length
  link=""
  for (i=0; i<coded.length; i++) {
    if (key.indexOf(coded.charAt(i))==-1) {
      ltr = coded.charAt(i)
      link += (ltr)
    }
    else {     
      ltr = (key.indexOf(coded.charAt(i))-shift+key.length) % key.length
      link += (key.charAt(ltr))
    }
  }
document.write("<a href='mailto:"+link+"'>stuur me dan een mailtje.</a>")
}
//-->
</script><noscript>Sorry, you need Javascript on to email me.</noscript></p>

.
Oh b.t.w. it's from here:

The issue lies within the wysiwyg editors, which do sanitise the code. What possible solutions do you have ...

1) put code into a codepage and echo every single line (have fun dowing that)
2) put the code into a HTML page and use include in a codepage/section to load the page (not shure if this will work though).
3) use cURL to inculde the HTML page if include is not active on your host.
4) last but not least just put the code into your template ... (do-oh)

Hope one of them works for you.

cheers

Another possible solution would be to modify the form module code so that the email address is within the code of the module and is not listed on the contact page.

I haven't done this but have thought about modifying the form module so that on the contact page I could allow the user to select who to send the email to (i.e. sales, marketing, accounting, webmaster) and then the module would use a table to associate the proper email address for each of these possible addressees to send the email. This prevents the email address from appearing in the contact page and also gives the user more control over where the email is sent to. Has anyone done this?

Hello Hans,

code does not work on WYSIWYG pages. So add a code page as additional section and place the code their. As you need ot output the whole Javascript within PHP, try the following code:

Code:

$js_text = <<< EOS
<script type="text/javascript" language="javascript">
<!--
{ coded = "5OSQjFZ95t@HuZ9M.Oh"
  key = "48TalNouG9wWzKbmRrxiksZh1QCfnUPvBeFXjI56M37y2DSOpJcVtALgEH0Ydq"
  shift=coded.length
  link=""
  for (i=0; i<coded.length; i++) {
    if (key.indexOf(coded.charAt(i))==-1) {
      ltr = coded.charAt(i)
      link += (ltr)
    }
    else {     
      ltr = (key.indexOf(coded.charAt(i))-shift+key.length) % key.length
      link += (key.charAt(ltr))
    }
  }
document.write("<a href='mailto:"+link+"'>stuur me dan een mailtje.</a>")
}
//-->
</script><noscript>Sorry, you need Javascript on to email me.</noscript></p>
EOS;

echo $js_text;

Regards Christian

[Edit]

Code:

$js_text = <<< EOS ... EOS;

is a so called heredoc syntax and can be used to output long strings

Thanks Klaus,  and Christian!
I tried the solutions offered by Klaus, but either they didn't work or it was not possible to implement them.
The solution offerd by Christian worked.
@ marathoner: modifying the form module is way byond my skills, as you'll understand from my posting, but I hope this is a way to hide an emailaddress in the form.
Thanks again
Hans
