{NOSPAM_EMAIL} Replacement Tag

marcus@localhorst · Post by **marcus@localhorst** » Wed 26. Jan 2005, 10:53

Holla,

I've wrote this tag to encode e-mail links to prevent for spam.

{NOSPAM_EMAIL:mail@adress.tld} will produce

<a href="mailto:%6D%61%69%6C%40%61%64%72%65%73%73%2E%74%6C%64">mail<span>@</span>adress<span>.</span>tld</a>

you can replace @ and . with any combination you want to confuse the robots.

UPDATE
it's better now

You can use now:
{NOSPAM_EMAIL:mail@adress.tld:linktext} this will produce

Code: Select all

<a href="mailto:%6D%61%69%6C%40%61%64%72%65%73%73%2E%74%6C%64">linktext</a>

just paste the code into a file inside the frontend_render folder and use the tag in your contentparts.

greetings marcus

Code: Select all

description:  1.{NOSPAM_EMAIL:mail@adress.tld} 
                this tag will encode your emailadress to hexcode 
                the output looks like this: 
                <a href="mailto:%6D%61%69%6C%40%61%64%72%65%73%73%2E%74%6C%64">mail<span>@</span>adress<span>.</span>tld</a>
							2.{NOSPAM_EMAIL:mail@adress.tld:Linktext}
							  the output looks like this: 
                <a href="mailto:%6D%61%69%6C%40%61%64%72%65%73%73%2E%74%6C%64">linktext/a>
								
notice:         these two vars replace @ and . with the chars you prefer like this: mail (at) adress (dot) tdl 
                $ats = "(at)"; 
                $dots = "(dot)"; 
                          
                look at this too:

Hi Marcus,

finally a replacement tag that does not affect the core code. Great!

@ Pappnase: Hi Oliver, new stuff for your Add On section in the docu site !

Yep very nice.... Maybe it can inspire other ppl to make replacement tags... this one could be a kind of "template"

Hi frold,

here we are again to discuss a general description for "how to create an extension or add on for phpwcms"...

i made this with basic php knowlege and the {TOPLEVEL} Tag as help.
Some things are unclear for me and i would like to know something more. for example about the frontend_init folder (i think it is for querys and the frontend_render folder is for display data)
well, a tutorial would be great

hi marcus!

Thank you for your Replacement Tag! This is a very good one!

I'd love to have such people like you with us at the dev-corner.

If you are interested in developing future phpwcms add-ons, please write me a PN or email or read my threat at:
Phpwcms-Discussion => Volunteers needed

well I found this on the docu pages...

$phpwcms["allow_ext_init"] = 0;

This function allows you to load your own PHP scripts before phpWCMS is loaded. Your files are stored in the following directory.
/phpwcms_template/inc_script/frontend_init
Default = 0 Forbidden / 1 = Allowed.

$phpwcms["allow_ext_render"] = 0;

If you use existing functions from the INIT folder for rendering the page.
These files can be rendered from the directory
/phpwcms_template/inc_script/frontend_render
Default = 0 Forbidden / 1 = Allowed.

Pappnase does not equal Oliver!

----------------------

Does this work in any way with the mail form content part??

@ marcus@localhorst:

Thank you for the good work!

Is it possible to enhance the Replacement Tag to show a alternative text instead of the email adress, for example

Code: Select all

<a href="mailto:eamil@adress.com>alternative text</a>

So the replacemant tag needs a further parameter "alttext" for example like:

{NOSPAM_EMAIL:mail@adress.tld:alttext}

Best regards
novallis

marcus@localhorst · Post by **marcus@localhorst** » Tue 1. Feb 2005, 17:01

mmm...
should be possible
{NOSPAM_EMAIL:name@domain.tld:alternative Text}
try this:

Code: Select all

function no_spam($mail='',$alt='') { 
// 1. just added a 2. parameter to the function ($alt)
      $str = "";          
      $a = unpack("C*", $mail); 
      foreach ($a as $b) 
         $str .= sprintf("%%%X", $b); 
             $str = "<a href=\"mailto:" . $str . "\">" . $alt . "</a>"; 
      return $str; 
   } 

if( ! ( strpos($content["all"],'{NOSPAM_EMAIL')===false ) ) { 
  $content["all"] = preg_replace('/\{NOSPAM_EMAIL:(.*?):(.*?)\}/e','no_spam("$1","$2");',$content["all"]);
//2. add a 2. regExpr to catch tha alternativ text ->NOSPAM_EMAIL:(.*?):(.*?)
//3. add the 2. parameter to the function "no_spam("$1","$2");" ($2 holds the catched alternative text
}

this is a quick and dirty hack but it works like you want.
(but only in this way not in both ways)

best
m.
